Fernando Javier León's questions

I want to input strings to an array in C, the code I have is this:

int main()
{
    
    int sizeA;
    printf("Tamanio de arreglo\n");
    
    scanf("%i", &sizeA);
    
    char names[sizeA];
    
    
    for(int i = 0; i < sizeA; i++){
        printf("Nombre %c\n", i+1 );
        scanf("%c", &names[i]);
    }
    

    
    printf("valores arreglo\n");
    
    for(int i = 0; i < sizeA; i++){
        printf("%c", names[i]);
    }



    return 0;
    
}

First of all I ask the size of the array, in case of entering 5as the length of the array, when I enter the value of the strings at the time of requesting the Nombrename, I get the name request twice, which in the end allows me to enter 2the string only times and not the 5ones you enter as length. How can I enter the 5 values? Thanks in advance. When I do it with integers it lets me enter the 5 values ​​correctly and with strings it doesn't.

I am using django rest framework to generate a file, I have this function in my views.py:

def InformacionBibTex(request, bloque, idUsuario):
   print('BLOQUE', bloque)

   #...
   return response
   

I use this function to use it in my urls.py:

urlpatterns = [
  path('informacion_bibtex/<slug:bloque>/<int:idUsuario>', views.InformacionBibTex),
]

slug:bloqueIn this url I pass a and a as parameters int:idUsuarioto be able to use them in my function.

I pass the parameters from my frontend service in Angular through a request Get:

generaInformacionBibTex(bloque, id_user){
    const httpOptions = {
      responseType: 'blob' as 'json',
    };
    return this.http.get(this.url + 'informacion_bibtex/' + bloque + '/' + id_user, httpOptions);
  }

The URL that I send to my server is this:

http://localhost:8000/api/informacion_bibtex/ARTÍCULOS/127

The problem I have is that when making the request to the server it gives me the following error

"GET /api/informacion_bibtex/ART%C3%8DCULOS/127 HTTP/1.1" 404 11500

This due to the tilde that it has ARTÍCULOS, the server puts various characters such as percentages and numbers.

The same thing happens with spaces:

"GET /api/informacion_bibtex/GRADO%20ACAD%C3%89MICO/127 HTTP/1.1" 404 11520

In this case what I send is:

http://localhost:8000/api/informacion_bibtex/GRADO ACADÉMICO/127

How can I make the server accept the request Getthat I make from my frontend with parameters that contain accents and spaces. I hope you can help me. Thank you!

I am comparing two arrays, which are as follows configuraionesPersonalizadas:

configuraionesPersonalizadas = [
    {
      id: 4163,
      bloque: 'GradoAcademico',
      atributo: 'id_docente',
      orden: 1,
      visible_cv_personalizado: true,
      mapeo: 'id_docente',
      id_user: 127,
    },
    {
      id: 4164,
      bloque: 'GradoAcademico',
      atributo: 'id',
      orden: 1,
      visible_cv_personalizado: true,
      mapeo: 'id',
      id_user: 127,
    },
    {
      id: 4165,
      bloque: 'GradoAcademico',
      atributo: 'fecha_emision',
      orden: 1,
      visible_cv_personalizado: true,
      mapeo: 'fecha_emision',
      id_user: 127,
    },
  ];

And configuraciones:

  configuraciones = [
    {
      id: 179,
      bloque: 'GradoAcademico',
      atributo: 'id',
      mapeo: 'Id Grado Académico',
      usuario: 1,
    },
    {
      id: 180,
      bloque: 'GradoAcademico',
      atributo: 'id_docente',
      mapeo: 'id Docente',
      usuario: 1,
    },
    {
      id: 181,
      bloque: 'GradoAcademico',
      atributo: 'fecha_emision',
      mapeo: 'Fecha Emisión',
      usuario: 1,
    },
    {
      id: 182,
      bloque: 'GradoAcademico',
      atributo: 'lugar_emision',
      mapeo: 'Lugar Emisión',
      usuario: 1,
    },
  ];

I have the following function:

 funcion() {
    this.configuraciones.forEach((atributo) => {
      let atribtutoOriginal = this.configuraionesPersonalizadas.find(
        (b) => b.atributo === atributo.atributo && b.bloque === atributo.bloque
      );

      if (
        atribtutoOriginal.bloque == atributo.bloque &&
        atribtutoOriginal.mapeo == atributo.mapeo
      )
        return;
      // console.log('sevaeditar', atributo, atribtutoOriginal);
      const objetoEditar = {
        id: atribtutoOriginal.id,
        bloque: atribtutoOriginal.bloque,
        atributo: atribtutoOriginal.atributo,
        orden: atribtutoOriginal.orden,
        visible_cv_personalizado: atribtutoOriginal.visible_cv_personalizado,
        mapeo: atributo.mapeo,
        id_user: Number(atribtutoOriginal.id_user),
      };

      console.log('objetoEditarconfiguraionesPersonalizadas', objetoEditar);
    });
  }

This function gets me when the mapeoarray field configuraionesPersonalizadasdoes not match the mapeoarray field, configuracionesin case it does not match, I create an object objetoEditarwith the value of mapeoso cofiguracionesthat I can edit it.

It works fine for me, the problem I have is that it only works when the length of the arrays configuraionesPersonalizadasand configuracionesare equal. In case it configuraionesPersonalizadashas less length it configurcionesthrows me the following error.

Error: Cannot read properties of undefined (reading 'mapeo')

How can I optimize or make it work for me without the need for the length of the arrays to be the same? Thanks in advance.

This is what I have so far: stackblitz

I have an interceptor which clones it requestand modifies it by headerssending it to Authorizationa tokenthat I retrieve from localstorage when I make a request to my api:

 intercept(request: HttpRequest<unknown>, next: HttpHandler): Observable<HttpEvent<unknown>> {
    
    const token:  string = localStorage.getItem('token');
    let req = request;
    if(token){
      req = request.clone( {
        setHeaders: {
          Authorization: `Token ${token}`
        }
      });
    } else{
      console.log("NOEXISTETOKEN")
    }
    
    return next.handle(req);
  }

It works fine for me, the problem I have is that I have a service which consumes another service that has nothing to do with my api:

public getJSON(): Observable<any> {
    return this.http.get(this.URL_ESQUEMA);
}

To consume this service I don't need to send it a tokenbut when making the request the interceptor sends it tokenand when it doesn't need tokenand send one it returns an error401 (Unauthorized)

How can I do so that in a request to a specific URL headersthe interceptors are not modified in order to access it without problems.

I have an arregloobject with nested arrays:

categorias =
  [
    {
      0: 'agosto', 'Manuel': [
        {
          id: 12,
          categoria: 'sociedad',
        },
        {
          id: 13,
          categoria: 'sociedad',
        },
      ],
    },
    {
      1: 'septiembre', 'Carlos': [
        {
          id: 14,
          categoria: 'deportes',
        }
      ],
    },
  ]

I need to display the following:

agosto, Manuel
12 - sociedad
13 - sociedad

septiembre, Carlos
14 - deportes 

I need to display the two keys I have on each object. I was trying to access the data, but I can't.

<div *ngFor ="let item of categorias | keyvalue"  >
  {{item.key}}  {{item.value}}
  <p *ngFor="let value of categorias[item.key]">
    {{ value }}
  </p>
</div>

I only get this output:

0 [object Object]
1 [object Object] 

How can I do to display the data I need and also if a button is pressed get the value of each key, for example if I need to send agostoy septiembreor Manuely Carlosas a parameter in a function:

funcion(key1, key2) {
  console.log(Key1, Key2)
}

That in case of selecting the first object the values ​​would be:

agosto, Manuel

I hope you can help me, thanks in advance.

I am using the library lodashin Angularto group this data:

data = 
[
   {
     hash: "13m49k9pg70b",
     fecha_registro: "2021-10-26T20:28:25.350000Z",
     id: 7791,
     nombre: "aprueba"
   },
   {
     hash: "13m49k9pg70b",
     fecha_registro: "2021-10-26T20:28:25.350000Z",
     id: 7792,
     nombre: "aprueba"
   },
   {
     hash: "1sd345612se",
     fecha_registro: "2021-11-08T21:22:25.350000Z",
     id: 7793,
     nombre: "btest"
   },
    {
     hash: "1sd345612se",
     fecha_registro: "2021-11-08T21:22:25.350000Z",
     id: 7794,
     nombre: "btest"
   },
    {
     hash: "asd1w345611s",
     fecha_registro: "2021-08-11T10:22:21.350000Z",
     id: 7794,
     nombre: "cvtest"
   },  

]

What I do is group the data by the properties nombre, hash, fecha_registroto do this in a function I do this:

this.confPersoDocenteClas = _.groupBy(data, (item) => {
    return [ item['nombre'], item['hash'], item['fecha_registro']];
});

console.log("DATA AGRUPADA", this.confPersoDocenteClas)

Which returns me correctly grouped data

aprueba,13m49k9pg70b,2021-10-26T20:28:25.350000Z: [{...}, {...}]
btest, 1sd345612se, 2021-11-08T21:22:25.350000Z: [{...}, {...}]
cvtest, asd1w345611s, 2021-11-08T10:12:21.350000Z: [{...}, {...}]

The "problem" I have is that it returns the data in alphabetical order of the key nombre, and what I need is that it returns me ordered by fecha_registro, from the most recent to the oldest, in this way:

btest, 1sd345612se, 2021-11-08T21:22:25.350000Z: [{...}, {...}]
cvtest, asd1w345611s, 2021-11-08T10:12:21.350000Z: [{...}, {...}]
aprueba,13m49k9pg70b,2021-10-26T20:28:25.350000Z: [{...}, {...}]

To try this I have added a line to the function indicated above in this way:

let datos  = _.orderBy(data, ['fecha_registro'], ['desc']); //linea agregada
this.confPersoDocenteClas = _.groupBy(datos, (item) => {
    return [ item['nombre'], item['hash'], item['fecha_registro']];
});

This sorts them but doing the grouping again sorts them back in alphabetical order, in this case by key nombre. How can I make it return ordered by fecha_registro? I hope you can help me, thanks in advance.

I have to generate a file .bibI do it in django rest framework, for it in different files like csv I have used the following.

response = HttpResponse(content_type='text/csv') 
response['Content-Disposition'] = 'attachment; filename="file.csv"'  

The issue is that I've been looking for how to make a response for downloading a file .bibbut I can't find what goes in content_typeit. I hope someone can help me. Thanks in advance.

I would like to know if there is any way that in my application when pressing the back button of a browser instead of being sent to the previous page, I was sent to a route that I have established.

//suponiendo que hay alguna forma de poner una ruta al botón de retroceder del navegador.
btnRetroceder(){
   this.router.navigate(['/dashboard']);
}

Do something "similar" to that, I'm curious if there is a way to do something like that. Or as another option you can't go back, or disable the browser's back button. Thanks in advance.

I have a table in which I show data that I get from my api. In my component .tsI do this to be able to access the data from my service, for this I do this.

 getBloques() {
    this.configuracioncvService.getBloques()
      .subscribe(res => {
        let bloquesOrdenados = _.orderBy(res,['ordenCompleto'], ['asc'])
        this.configuracioncvService.bloques = bloquesOrdenados;
        console.log('BLOQUESRESTAPI', bloquesOrdenados)
      })
  }

In my service I have this:

getBloques() {
    return this.http.get<Bloque[]>(this.URL_BLOQUES);
}

And in my htmlto show this data I do this:

 <table class="table" id="tabla">
      <thead>
           <tr class="d-flex">
                <th class="col-3">Bloque</th>
                <th class="col-3">Orden</th>
                <th class="col-3">Guardar</th>
                <th class="col-3">Ingresar a Bloque</th>
            </tr>
       </thead>
       <tbody>
            <tr class="d-flex" *ngFor="let bloque of configuracioncvService.bloques">
                 <td class="col-md-3">{{bloque.nombre}}</td>
                 <td class="col-md-3">
                      <mat-form-field>
                           <input type="number" matInput placeholder="Orden" [value]="bloque.ordenCompleto" [(ngModel)]="bloque.ordenCompleto">                                             
                      </mat-form-field>
                 </td>
                 <td class="col-md-3">
                      <button class="btn btn-secundary" (click)="editBloque(bloque)">
                           <i class="material-icons">save</i>
                      </button>
                 </td>
                 <td class="col-md-3">
                      <button mat-raised-button color="primary" [routerLink]="['/bloque-completo/', bloque.nombre]">
                           <i class="material-icons">east</i>
                      </button>
                 </td>
            </tr>
       </tbody>
 </table>

I show the data in the table, and in that table I have an input so that the value of the column can be edited orden, my method to edit is this

editBloque(bloque: Bloque){
    this.configuracioncvService.putBloque(bloque).subscribe(res =>{
          console.log('editado', res)
      });
 }

Everything works correctly for me, the "problem" I have is that in my html for each object I have a button, so every time I change a data, I have to click on the button so that this data is edited, as in this image it is as I currently have.

My question is how can I make a single button that edits all the objects without having to save them one by one, as I have it now. What I am looking to get is something like this.

Excuse me for the images, it is so that I can better understand what I am trying to do. I hope you can help me or give me a guide on how to get what I want. Thanks in advance.

EDITED: For now I've been trying this on stackblitz https://stackblitz.com/edit/angular-formgroup-ngxxam?file=app%2Fapp.component.ts But I don't know how to loop through the value of formthe in the method onMy()and do the editing .

I have a list like this:

bloqueOrdenApi = [{'Articulos': 0}, {'Libros': 0}, {'Proyectos': 5}, {'GradoAcademico': 7}, {'Capacitacion': 8}]

I am trying to remove the dictionaries whose value is 0, in this case Articles and Books, I am doing this:

for b in bloqueOrdenApi:
  for k, v in b.items():
    if v == 0:
      del bloqueOrdenApi[v]
print(bloqueOrdenApi)

But I get as output this:

bloqueOrdenApi = [{'Libros': 0}, {'Proyectos': 5}, {'GradoAcademico': 7}, {'Capacitacion': 8}]

Only the Articles element is deleted and Books are not. How can I remove all dictionaries that have a value of 0? I hope you can help me. Thanks in advance.

I am generating a word file with pypandoc, I save it in a variable called output and then I make a response where I send that variable so that the document is downloaded

logo = str(settings.BASE_DIR) + '/cv_api/templates/logoutpl.png'
context = {'listaFinal': listaFinal, 'docente': docente, 'logo': logo}

html_string = render_to_string('documento.html', context)

output = pypandoc.convert(source= html_string, format='html', to='docx', 
outputfile=str(Path.home() / "documento") + 'cv.docx', extra_args='--css=/templates/pdf_gen.css')
    
response = HttpResponse( output, content_type='application/msword')
response['Content-Disposition'] = 'attachment; filename="cv.docx"'

return response

Here I do the response response = HttpResponse( output, content_type='application/msword'), but the document is saved in the place where it is indicated in the outputfile outputfile=str(Path.home() / "documento") + 'cv.docx'In this directory I download the document with the data, but in the response I download an empty word document, how can I do so that in the response I downloaded the document that is generated in the output variable. I hope you can help me. Thanks in advance

I have a data like this in which I have a dictionary with lists that have dictionaries:

bloqueAtributos = {
   "Articulos":[
      {
         "id":3042,
         "titulo":"Propuesta de Investigación Socioeducativa de la UTPL",
         "keywords":"",
         "link_articulo":""
      },
      {
         "id":3043,
         "titulo":"Prueba",
         "keywords":"pruebas",
         "link_articulo":""
      },
      {
         "id":3044,
         "titulo":"Prueba",
         "keywords":"pruebas",
         "link_articulo":""
      }
   ],
   "Libros":[
      
   ],
   "Proyectos":[
      {
         "codigo_proyecto":""
      },
      {
         "codigo_proyecto":""
      }
   ],
   "GradoAcademico":[
      
   ],
   "Capacitacion":[
      {},
      {} 
   ]
}

And I'm trying to delete empty lists and lists with empty dictionaries, for which I do this:

bloquesInfoRestante = {k:v for k,v in bloqueAtributos.items() if v !=[] and v !=[{}]}
print(bloquesInfoRestante)

With that I can eliminate the lists that are empty. But not the lists that are found with more than one empty dictionary.

With what I have now it returns me this:

bloquesInfoRestante = {
   "Articulos":[
      {
         "id":3042,
         "titulo":"Propuesta de Investigación Socioeducativa de la UTPL",
         "keywords":"",
         "link_articulo":""
      },
      {
         "id":3043,
         "titulo":"Prueba",
         "keywords":"pruebas",
         "link_articulo":""
      },
      {
         "id":3044,
         "titulo":"Prueba",
         "keywords":"pruebas",
         "link_articulo":""
      }
   ],
   "Proyectos":[
      {
         "codigo_proyecto":""
      },
      {
         "codigo_proyecto":""
      }
   ],
   "Capacitacion":[
      {},
      {}
   ]
}

As you can see, it only eliminates the empty lists, but not the lists with empty dictionaries. My question is how can I remove the lists with empty dictionaries as well. I hope you can help me. Thanks in advance

I have this data called RemainingBlocks and RemainingInfoBlocks :

bloquesRestantes = ['Articulos', 'Proyectos']
bloquesInfoRestante = {
   "Articulos":[
      {
         "pais":"Peru",
         "indice":"Artículos Publicados de Divulgación Local",
         "fecha_publicacion":"2005-02-04",
         "mapeo":[
            "Pais",
            "Indice",
            "Fecha Publicacion"
         ]
      },
      {
         "pais":"Turquia",
         "indice":"Artículos",
         "fecha_publicacion":"1995-02-04",
         "mapeo":[
            "Pais",
            "Indice",
            "Fecha Publicacion"
         ]
      }
   ],
   "Proyectos":[
      {
         "fecha_inicio":"2005-02-01",
         "codigo_proyecto":"",
         "descripcion":"Asadsadsadsadsa sadsadsadsa",
         "mapeo":[
            "Fecha Inicio",
            "Codigo Proyecto",
            "Descripcion",  
         ]
      },
      {
         "fecha_inicio":"2008-08-08",
         "codigo_proyecto":"008",
         "descripcion":"Descripcion test",
         "mapeo":[
            "Fecha Inicio",
            "Codigo Proyecto",
            "Descripcion",  
         ]
      }
   ]
}

I use that information and through the zip() function I map the information with the data element mapeoin bloquesInfoRestantethe following way:

listaData = dict()
for i in bloquesRestantes:
  for bloqueInformacion in bloquesInfoRestante[i]:
    resultados = dict(zip(bloqueInformacion['mapeo'], bloqueInformacion.values()))
    listaData[i] = [{k:v for k,v in resultados.items()}]
print(listaData)

So far so good, now in the line where it is listaData[i]what I try is that for each dictionary key bloquesInfoRestantethat are 'Articles', 'Projects' . to be able to obtain the information of the list of each one.

But the way I'm doing it, I'm only getting the last element of each key in bloquesInfoRestantethe following way:

listaData = {
   "Articulos":[
      {
         "Pais":"Turquia",
         "Indice":"Artículos",
         "Fecha Publicacion":"1995-02-04"
      }
   ],
   "Proyectos":[
      {
         "Fecha Inicio":"2008-08-08",
         "Codigo Proyecto":"008",
         "Descripcion":"Descripcion test",
      }
   ],
}

When my intention is to get the data like this:

listaData = {
   "Articulos":[
      {
         "Pais":"Peru",
         "Indice":"Artículos Publicados de Divulgación Local",
         "Fecha Publicacion":"2005-02-04"
      },
      {
         "Pais":"Turquia",
         "Indice":"Artículos",
         "Fecha Publicacion":"1995-02-04"
      }

   ],
   "Proyectos":[
      {
         "Fecha Inicio":"2005-02-01",
         "Codigo Proyecto":"",
         "Descripcion":"Asadsadsadsadsa sadsadsadsa",
      }, 
      {
         "Fecha Inicio":"2008-08-08",
         "Codigo Proyecto":"008",
         "Descripcion":"Descripcion test",
      }
   ],
}

My question is how can I get the information in this way. I hope you can help me and thanks in advance.

I have two types of datas like the following:

data1 ={
     'ArticulosAutores': [], 
     'LibrosAutores': [], 
     'Articulos': [
          {
           'abstract': 'El artículo hace una reseña', 
           'keywords': '', 
           'indice': 'Artículos Publicados de Divulgación Local', 
           'fecha_publicacion': '2005-02-04', 
           'mapeo': [ 
                'Abstract', 
                'Keywords', 
                'Indice', 
                'Fecha Publicacion'
            ]
           }
      ], 
      'Libros': [], 
      'Proyectos': [
           {'fecha_inicio': '2005-02-01', 
           'codigo_proyecto': '', 
           'descripcion': 'Asadsadsadsadsa sadsadsadsa', 
           'mapeo': [
                'Fecha Inicio', 
                'codigo_proyecto', 
                'descripcion',  
            ]
           }
       ]
 }

data2 = [
       'ArticulosAutores', 
       'LibrosAutores', 
       'Articulos', 
       'Libros', 
       'Proyectos',  
       ]

My question is, how can I eliminate from data2the lists that are empty in data1for example ArticulosAutores LibrosAutoresand Librosare empty in data1then based on that in data2obtaining a result like the following:

data2 = ['Articulos', 'Proyectos']

I hope you can help me. Thanks in advance.

I have a dictionary like this which has nested lists:

data =
{
    "id": 212,
    "primer_apellido": "Apellido1",
    "segundo_apellido": "Apellido2",
    "primer_nombre": "Nombre1",
    "segundo_nombre": "Nombre2",
    "genero": "masculino",
    "lugar_de_nacimiento": "Lugar Nacimiento",
    "facultad": "",
    "departamento": "",
    "categoria": "P2",
    "apellido": "Apellido1 Apellido2",
    "nombre": "Nmbre1 Nombre2",
    "related": {
        "articulos": [
            {
                "id": 2557
            },
            {
                "id": 2256
            },
            {
                "id": 2312
            }
        ],
        "libros": [
            {
                "id": 535
            },
            {
                "id": 537
            },
            {
                "id": 538
            }
        ],
        "proyectos": [],
        "grado-academico": [],
        "capacitacion": []
    }
}

Enter the element relatedand take out articulosas follows:

listaidArticulos = []
for i in data['related']['articulos']:
  listaidArticulos.append(i)

print('lista-->>>>>>>>>',listaidArticulos)

Which returns me:

lista-->>>>>>>>> [{'id': 2557}, {'id': 2256}, {'id': 2312}]

My question is, how can I access articles, books, projects, academic degree, training and obtain the values ​​dynamically, that is, I do not have to put for i in data['related']['articulos']:or for i in data['related']['libros']indicate which one I want to access. I hope you can help me. Thanks in advance.

I have a data in which I have a dictionary with nested lists, my data is as follows:

data = {
   'Articulos': [
     {
      'id': 1, 
      'titulo': 'Titulo 1', 
      'keywords': 'keywords1', 
      'descripcion': 'asdsadsadsasdadsa', 
      'nombre_proyecto': 'Diferentes dentro del del Conocimiento Tradicional del Pueblo Saraguro', 
      'link_articulo': 'https://linkarticulo1', 
      'mapeo': 
           [
            'Id', 
            'Titulo', 
            'Keywords', 
            'Descripcion', 
            'Nombre Proyecto', 
            'Link Articulo'
           ]
      }, 
      {
       'id': 3, 
       'titulo': 'Titulo 2', 
       'keywords': 'keywords2', 
       'descripcion': 'El cancerpor esta enfermeda', 
       'nombre_proyecto': 'PROSPECCION DE', 
       'link_articulo': 'https://linkarticulo2', 
       'mapeo': 
            [
               'Id', 
               'Titulo', 
               'Keywords', 
               'Descripcion', 
               'Nombre Proyecto', 
               'Link Articulo'
             ]
      }
    ] 
   'Proyectos': [
      {
       'codigo_proyecto': 'Proy_001', 
       'mapeo': 
            [
             'Codigo Proyecto'
            ]
       }, 
       {
        'codigo_proyecto': 'PROY_CBCM_0011', 
        'mapeo': 
             [
              'Codigo Proyecto'
             ]
       }
    ]
}

The problem I'm having is that I can't pass the values ​​found in mapeoto the values ​​found on mapeo. I need the values ​​found in mapeoto become the keys of the values ​​found for example in Articulosand get something like this:

Id: 1
Titulo: Titulo 1
Keywords: keywords1 
Descripcion: asdsadsadsasdadsa 
Nombre Proyecto: Diferentes dentro del del Conocimiento Tradicional del Pueblo Saraguro 
Link Articulo: https://linkarticulo1

Id: 3
Titulo: Titulo 2
Keywords: keywords2
Descripcion: El cancerpor esta enfermeda
Nombre Proyecto: PROSPECCION DE
Link Articulo: https://linkarticulo2

Same with Proyectosto get the following:

Codigo Proyecto: Proy_001
Codigo Proyecto: PROY_CBCM_0011

I really don't know how to do it. I hope you have understood me and you can help me solve this. Thanks in advance.

I have a view in django rest framework that allows me to generate a pdf, I want to get the data from models, I have this function in views.py:

def generaPdf(request):
    
    stu = models.ConfiguracionCv_Personalizado.objects.filter(id_user=4)
    serializer = ConfiguracionCv_PersonalizadoSerializer(stu, many=True)
    print(serializer.data)
    json_data = JSONRenderer().render(serializer.data)

    
    # PDF = generapdf.PDF
    pdf = PDF()
    pdf.alias_nb_pages()
    pdf.add_page()
    pdf.set_font('Times', '', 11)
    for k, v in json_data.items():
        pdf.cell(0, 10, f"{k}: {v}", 0, 1)
    pdf = pdf.output(dest='S').encode('latin-1')
    response = HttpResponse(pdf, content_type='application/pdf')
    response['Content-Disposition'] = 'attachment; filename="mypdf.pdf"'
    return(response)

In serializers.pyI have this:

class ConfiguracionCv_PersonalizadoSerializer(serializers.ModelSerializer):
    class Meta:
        model = ConfiguracionCv_Personalizado
        fields = ('__all__')

I am trying to convert models.ConfiguracionCv_Personalizado.objectsto json to loop through it in the for and add the information to the pdf, but I am getting this error 'bytes' object has no attribute 'items'. How can I convert models.ConfiguracionCv_Personalizado.objectsit to json and be able to go through it in the for. I hope you can help me. Thanks in advance.

I am using reportlab to generate pdf. I have this function in django rest framework, in which I have a dictionary called data, I am doing a for to go through that data and show its key and value in the pdf, for this I do this:

@api_view()
def hello_world(request):
  
   todos =
[
   {
      primer_apellido : Castro,
      segundo_apellido : Mendieta,
      primer_nombre : José,
      segundo_nombre : Raúl,
      genero : masculino,
      lugar_de_nacimiento : Cuenca - Azuay,
      fecha_de_nacimiento : 1967-10-20,
      provincia : Loja,
      canton : Cuenca,
      ciudad : Loja,
      parroquia : El Vecino,
      direccion : Turunuma Alto. Urb. Elite. Casa A1.,
      telefono_institucion : 13213213,
      email_principal : [email protected]
   }
]
 
    buffer = io.BytesIO()

    # Create the PDF object, using the buffer as its "file."
    p = canvas.Canvas(buffer)

    # # Draw things on the PDF. Here's where the PDF generation happens.
    # # See the ReportLab documentation for the full list of functionality.

    from reportlab.lib import colors 
    from reportlab.lib.units import inch 
    y = x = 0
    dy = inch*3/4.0
    dx = inch*5.5/5
    w = h = dy/2
    rdx = (dx-w)/2    
    rdy = h/5.0
    texty = h+2*rdy    
    for todo in todos:
        p.drawString(x+dx/2, y+texty, todo, todos[todo])        
        x = x+dx    
        y = y + dy
        x = 0
    
    # Close the PDF object cleanly, and we're done.
    p.showPage()
    p.save()

    # FileResponse sets the Content-Disposition header so that browsers
    # present the option to save the file.
    buffer.seek(0)

    return FileResponse(buffer, as_attachment=True, filename='hello.pdf')

I use the drawStringreportlab function, but it only lets me do this p.drawString(x+dx/2, y+texty, todo)so I can display only the key and not the key and value. How can I make the key and the value be displayed or if there is any other reportlab function to be able to do it. I hope you can help me. Thanks in advance

Hello I have two objects in python, the first one:

 completos = [
        {
        "id": 83,
        "bloque": "Proyectos",
        "atributo": "fecha_cierre",
        "orden": 1,
        "visible_cv_resumido": true,
        "visible_cv_completo": true,
        "mapeo": "fecha_cierre",
        "administrador": 1
    },
    {
        "id": 84,
        "bloque": "Proyectos",
        "atributo": "id",
        "orden": 1,
        "visible_cv_resumido": true,
        "visible_cv_completo": false,
        "mapeo": "id",
        "administrador": 1
    },
    {
        "id": 85,
        "bloque": "Proyectos",
        "atributo": "fecha_inicio",
        "orden": 1,
        "visible_cv_resumido": true,
        "visible_cv_completo": true,
        "mapeo": "fecha_inicio",
        "administrador": 1
    },
]

And another fix like this:

data = [
 {
            "id": 1,
            "fecha_inicio": "2005-02-01",
            "fecha_cierre": "2012-01-01",
            "codigo_proyecto": "",
            "nombre_proyecto": "Diferentes dentro del del Conocimiento Tradicional del Pueblo Saraguro",
            "descripcion": "",
            "tipo_proyecto": 65,
        },
        {
            "id": 3,
            "fecha_inicio": "2008-01-01",
            "fecha_cierre": "2012-06-30",
            "codigo_proyecto": "PROY_CBCM_0011",
            "nombre_proyecto": "PROSPECCION DE PRINCIPIOS ACTIVOS ANTICANCEROSOS DE LA FLORA DEL SUR DEL ECUADOR.",
            "descripcion": "El cancer constituye una de las principales causas de muerte, se estima que para el 2020 cerca de 13 millones de personas falleceran por esta enfermedad. Por tanto, el cancer constituye un problema de salud mundial y ocupa un lugar de importancia en lo",
            "tipo_proyecto": 65,
        }
]

How can I do that based on the field visible_cv_completoof the complete array, if that field is true I can obtain the information for example "atributo": "fecha_cierre"from the data array and obtain "fecha_cierre": "2012-01-01" or "atributo": "fecha_inicio"and from the data array obtain "fecha_inicio": "2005-02-01"In the first array called complete I have in the field atributowhat I want to obtain from the array data. I do not know how to do it. I hope you can help me. Thanks in advance.

I have data with this structure:

data = {
   test: [
     {
       nombre_cv: "test",
       bloque: "Articulos",
       atributo: "titulo",
       visible_cv_personalizado: true
     }
   ],
   convocatoria: [
     {
       nombre_cv: "test",
       bloque: "Articulos",
       atributo: "id",
       visible_cv_personalizado: true
     },
     {
       nombre_cv: "test",
       bloque: "Articulos", 
       atributo: "titulo", 
       visible_cv_personalizado: true
     }
   ]
 }

I want the test and the call to be displayed with their properties, for this I use ngFor in the following way:

 <div class="card" *ngFor="let item of data | keyvalue">
      Key: <b>{{item.key}},</b> value: <b> {{item.value}} |</b>
 </div>

But at the time of displaying on the screen it returns me this:

Key: call, value: [object Object] | Key: test, value: [object Object],[object Object]

As you can see, it returns the key, but the properties come out with:

[objectObject],[objectObject].

How can I make it show me all the test and call properties? I thank you in advance, I hope you can help me.
