Rafael Monroy Rodriguez's questions

Hello, I am trying to use useNavigationto move between screens but I get an error in the DetailScreen, I was looking for information about it and I think it is because in version 6 of react they made a change in the use of navigation.

import { useNavigation } from '@react-navigation/core' import React from 'react' import { Button, Text, View } from 'react-native'

export const HomeScreen = () => {
    const navigation = useNavigation();
    return (
        <View>
            <Text>Home Screen</Text>

            <Button
                title="ir detalle"
                onPress={()=>navigation.navigate('DetailScreen')}
            />
        </View>
    )
}

Can someone help me by providing information about that, I was looking in the official documentation but I didn't find something clear. Thank you

I am doing an if in which I type 2 alphabets separated by commas and join them, for this I am doing the following:

if op1 == str(2):
         c1 = set(input('Ingrese el alfabeto 1 separado por comas: '))
         c2 = set(input('Ingrese el alfabeto 2 separado por comas: '))
         print(f'A U B: {c1 | c2}')

It unites them without problem but when printing the response by entering values ​​for c1 = 'a,b,c' y c2 = 'd,e,f'I get the following:

A U B: {'e', 'f', ',', 'b', 'c', 'd', 'a'}

Why does it show me messy and because in a position I get ','that I could be failing? Thank you

Hello, I just installed react nativeand I had no problem until the step of putting the following comando:

npx react-native run android

When putting the command I get the following error

Any solution? Thanks.

I am trying to make a program which tells me the words of a text that contains 4 sentences but it should only count the word 1 time per sentence, what happens to me is that when counting them it counts the word only once. How could I solve this?

I attach the text of which I have to do that validation.

Podador que podas la parra, que parra podas?
Podas mi parra o tu parra podas?
Ni podo tu parra, ni mi parra podo,
que podo la parra de mi tio Bartolo que apodase tolo. 

In my case it counts me 1 times "parra" which should be 4 times. (those that are repeated in the same sentence are not counted)

Thanks.

Attached code.

def lim(x):
x=x.lower()
x=x.rstrip('?')
x=x.rstrip('.')
x=x.rstrip(',')
x=x.rstrip(':')
x=x.rstrip(';')
return x

a=open('discurso.txt','r')
palabras={}
for i in a:
  p=i.split()
  print(p)
  for j in p:
    for k in p:
        j=lim(j)
        if len(j)>4 and j!=k:
            if j not in palabras:
                palabras[j]=1
print(palabras)

I am making a formula excelto subtract some cells depending on a logical value

=SI(Y(G11=DATOS!D2; B11="N2");C6-C11;0)

With this formula the value that I put in quantity is subtracted from the canvas number giving me the result, but this formula only works for that row, I am seeing how I can accommodate the formula so that it works for the rest of the rows and not only in row 11, I mean that if I put other data in row 12 and put a new amount, that amount is also subtracted with the canvas number and gives me the result in cell C7.

In the formula I am being very specific with the fields, for example saying B11="N2"but I also need that B12="N2"and so on with the cells down so that this formula works for the rest of the rows.

I am doing a query eloquentto fetch the data that is on one date or another, I am doing it as follows:

$eneP= tbl_calibracion::where('cal_usu_id',$onlyId)
    ->whereDate('cal_proximaCalibracion','=','2019-01-01 00:00:00')
    ->orWhere('cal_proximaCalibracion','=','2020-01-01 00:00:00')
    ->count();

The problem is that it brings me 34 records when it should bring 4, I made the query in mysqland it worked for me like this:

SELECT count(cal_id)as id FROM `tbl_calibracion` WHERE cal_usu_id='7' and (cal_proximaCalibracion='2019-01-01 00:00:00' or cal_proximaCalibracion='2020-01-01 00:00:00')

In MySQLI got 34 records if I didn't put the parentheses but errorhow can I solve that with eloquent?

Hello, I am trying to delete all the data from a table mysqlwith a button from my project laravel, I am doing it in the following way but it does not work for me, it comes out pagina expirada, the code of my controller is the following.

public function borrarDatos(){
      $marca=tbl_marca::all();
      $marca->delete();
      return back()->with('success', 'Datos Borrados Satisfactoriamente.'); 
    }

In my view I have the following

    <form action="{{ route('borrar') }}" class="form-horizontal" method="post" enctype="multipart/form-data">
      <button class="btn btn-danger" type="submit">Eliminar Datos</button>
   </form>

And my route is the following

Route::post('EliminarDatos', 'TestController@borrarDatos')->name('borrar');

How could I solve it? Thank you.

I find myself making a registration form but I encounter a problem, what happens is that when I start the form it shows me the fields "CECO", "ADDRESS", "LEADER". Which shouldn't be that way, what I'm looking for is that when I start it only shows me "user" and "password" and if I select a role, then it shows me the other fields. Another problem that I find is in the button since having a label <a>only takes me the button if I select it in "return", if I select in the area of ​​the button (not in the text) it does not take it. Any help is very welcome. Thank you

I attach the code of the form along with the script used:

      function comprobar(){
      var etiqueta = document.getElementById('datos');
      var source = document.getElementById('rol');

        if(source.selectedIndex >=1)
        {
          etiqueta.style.display = 'block';

        }
        else
        {
          etiqueta.style.display = 'none';
                    $('#datos').removeAttr('style');
                      $('#datos').hide();
        }
      }

Hi , I'm trying to count the rows of a table htmland show them with a labelbut I can't find how to do it, I found a way to do it with javaScriptbut the function calls it by means of a onclicklike this:

    <html>
    	<head>
    		<title>Ejercicio</title>
    	</head>
    	<script type="text/javascript" src="../js/jquery-1.10.2.js"></script>
    	<script>
    		function contarFilas() {
    			var $num = document.getElementById('tblUsuario').getElementsByTagName('tr').length - 1;
    			alert($num);
    		}
    	</script>
    	<body>
    		<table border="1" id="tblUsuario">
    			<tr>
    				<th>Nombre</th>
    				<th>Apellido</th>
    			</tr>
    			<tr>
    				<td>Hinata</td>
    				<td>Hyuga</td>
    			</tr>
    			<tr>
    				<td>Yuno</td>
    				<td>Gasai</td>
    			</tr>
    			<tr>
    				<td>Asuna</td>
    				<td>Yuuki</td>
    			</tr>
    		</table>
    		<input type="submit" value="Enviar" onclick="contarFilas()"/>
    	</body>
    </html>

But as I say, I'm not looking for the number of rows to come out like this, what I'm looking for is for it to come out in a label above the table. How could I do it?

Thanks.

Hello , I am trying to enter some data through a file excelbut I need it to be imported from a specific sheet, I was consulting the documentation of laravel excel 3.1but I do not understand very well how to do it, I have the following:

controller import:

class Import implements WithMultipleSheets 
{
    public function sheets(): array
    {
        return [
            'importar' => new InstrumentosImport(),
            'importar' => new CalibracionImport(),
        ];
    }
}

InstrumentsImport (driver)

class InstrumentosImport implements ToModel,WithHeadingRow
{


    public function model(array $row)
    {
        $tipo = tbl_tipo_instrumento::firstOrCreate([
            'tipo_nombre' => $row['tipoinstrumento']
        ]);
        //dd($row);
        //dd($row['tipo']); //ver si el dato llega
        //Si no encuentra el dato en la tabla lo crea

        /*$tipo = tbl_tipo_instrumento::firstOrCreate(
            ['tipo_nombre' => $row['tipoinstrumento']],//busca
            ['tipo_nombre'=>$row['tipoinstrumento']] //crea
        );*/

        $marca = tbl_marca::firstOrCreate(
            ['mar_nombre' => $row['marca']],
            ['mar_nombre'=>$row['marca']]
        );

        $id = Auth::id(); //trae el id del usuario logeado

        return new tbl_instrumentos([
            'ins_codigo'   => $row['codigo'],
            'ins_observacionInicial'   => $row['observacioninicial'],
            'ins_proximaCalibracion'=>$row['proximacalibracion'],
            'ins_fechaUltimaCalibracion'=>$row['ultimacalibracion'],
            'ins_claseOexactitud'    => $row['claseoexactitud'],
            'ins_nSerie' => $row['nserie'],
            'ins_divOescala'=>$row['divoescala'],
            'ins_consecutivoInterno' => $row['consecutivointerno'],
            'ins_observaciones' =>$row['observaciones'],
            'ins_observacionFinal' => $row['observacionfinal'],
            'ins_magnitud' => $row['magnitud'],
            'ins_modelo' => $row['modelo'],
            'ins_codActividad' => $row['codigoactividad'],
            'ins_area' => 'null',
            'ins_usu_id' =>  $id,
            'ins_tipo_id' => $tipo->tipo_id,
            'ins_mar_id' => $marca->mar_id,
        ]);
    }
    public function headingRow(): int
    {
        return 5;
    }

It is not very clear to me if the sheets function should be put in the part of my import instruments or where I leave it is fine, or if I have to make a change in this line that I have in the main controller Excel::import(new InstrumentosImport,$request->import_file);

Hello , I am inserting data through a file exceland I am implementing the method firstOrCreatefor one of my tables, the problem is that it does not insert the data.

 public function model(array $row)
{



    //TABLA INSTRUMENTOS
    $tipo = tbl_tipo_instrumento::firstOrCreate([
        'tipo_nombre' => $row[14]
    ]);
    $marca = tbl_marca::firstOrCreate([
        'mar_nombre' => $row[15]
    ]);
    $id = Auth::id(); //trae el id del usuario logeado


    return new tbl_instrumentos([
        'ins_codigo'   => $row[0],
        'ins_observacionInicial'   => $row[4],
        'ins_claseOexactitud'    => $row[6],
        'ins_nSerie' => $row[1],
        'ins_divOescala'=>$row[5],
        'ins_claseOexactitud' =>$row[6] ,
        'ins_consecutivoInterno' => $row[7],
        'ins_observaciones' =>$row[8],
        'ins_observacionFinal' => $row[9],
        'ins_magnitud' => $row[10],
        'ins_modelo' => $row[11],
        'ins_codActividad' => $row[12],
        'ins_area' => 'null',
        'ins_usu_id' =>  $id,
        'ins_tipo_id' => $tipo->tipo_id,
        'ins_mar_id' => $marca->mar_id,
    ]);


}

That is the code that I am using and my model is the following:

class tbl_marca extends Model
{
use Authenticatable;

public $timestamps = false;
public $table="tbl_marca";
protected $primaryKey = 'mar_id';
protected $fillable = [ 'mar_nombre'];

}

If I enter the data manually in phpmyadminthe search without problems, $row[15] y $row[14]the names of each one are there. What could be the fault? I'm usinglaravel 6

Thank you

I am loading data from a file excelto myself base de datosbut in one foraneaI need to call the iduser who is logged in to be able to register it, I am doing it in the following way:

Controller code (import)

public function model(array $row)
{
    $id=Auth::tbl_usuario()->usu_id;

    $tipo=DB::table('tbl_tipo_instrumento')->select('tipo_id')->where ('tipo_nombre','=',$row[14])->get();
    $marca=DB::table('tbl_marca')->select('mar_id')->where('mar_nombre','=',$row[15])->get();
    $usu = DB::table('tbl_usuario')->select('usu_id')->where('usuario','=',$row[13])->get();

    return new tbl_instrumentos([
        'ins_codigo'   => $row[0],
        'ins_observacionInicial'   => $row[4],
        'ins_claseOexactitud'    => $row[6],
        'ins_nSerie' => $row[1],
        'ins_divOescala'=>$row[5],
        'ins_claseOexactitud' =>$row[6] ,
        'ins_consecutivoInterno' => $row[7],
        'ins_observaciones' =>$row[8],
        'ins_observacionFinal' => $row[9],
        'ins_magnitud' => $row[10],
        'ins_modelo' => $row[11],
        'ins_codActividad' => $row[12],
        'ins_area' => 'null',
        'ins_usu_id' =>  $id,
        'ins_tipo_id' => $tipo,
        'ins_mar_id' => $marca,
    ]);

But when uploading the file excelI get the following error:

Method Illuminate\Auth\SessionGuard::tbl_usuario does not exist.

Additionally codigo, I attach my model:

class tbl_usuario extends Model implements AuthenticatableContract
 {
use Authenticatable;

public $timestamps = false;
public $table="tbl_usuario";

 }

How can I solve this problem, thanks.

Hello , I am trying to load myself base de datosthrough laravel excel 3.1information that comes from a file excelwhich I load through an inputattachment my tables of thebase de datos

Attached codigowhy I am doing the insert to me base de datoswith the file Excel:

Controller code (import)

namespace App\Imports;

use App\tbl_instrumentos;
use Maatwebsite\Excel\Concerns\ToModel;

class InstrumentosImport implements ToModel
 {

  public function model(array $row)
   {
     return new tbl_instrumentos([
     'ins_codigo'   => $row[0],
     'ins_observacionInicial'   => $row[1],
     'ins_claseOexactitud'    => $row[2],
  ]);
 }
}

Additionally I add the one códigoof my main controller:

class TestController extends Controller
{

 public function importExportView()
  {
  $data=DB::table('tbl_instrumentos')->orderBy('ins_id','DESC')
        ->get();
  return view('importar',compact('data'));
  }

  public function exportExcel($type) 
  {
   return Excel::download(new InstrumentosExport, 'instrumentos.'.$type);
  }

  public function importExcel(Request $request) 
  {
    $this->validate($request, [
    'select_file'  => 'required|mimes:xls,xlsx'
  ]);
  Excel::import(new InstrumentosImport,$request->import_file);

  return back()->with('success', 'Datos Excel Importados 
    Satisfactoriamente.');
  }

The import_fileone I have in my controller (import) comes from my view through a inputwhich is the following:

 <input type="file" name="import_file" />

In that example that I have, I am only collecting 3 data from myself excelbut I want to add more data, therefore, as you can see in base de datosan instrument, it has several calibrations, so when I enter all that data (I plan to enter the data of the instrument and the calibration at once) how do you determine by foraneawhich instrument is calibrated, and also the brand and type of instrument that will also be inserted at once, or enter brand and type first and then the other?

How could I structure that part, Thank you.

Hello , I am trying to open a modal through a selectand I have the following codehtml

<select id = "numbers" onchange = "myFunction()">
 <option value = "1">1</option>
 <option value = "2">2</option>
 <option value = "3">Click me !</option>
</select>

<div class="container">
 <h2>Basic Modal Example</h2>
 <!-- Trigger the modal with a button -->
 <!-- Modal -->
 <div class="modal fade" id="myModal" role="dialog">
   <div class="modal-dialog">
   <!-- Modal content-->
    <div class="modal-content">
     <div class="modal-header">
      <button type="button" class="close" data-dismiss="modal">&times; 
      </button>
      <h4 class="modal-title">Modal Header</h4>
    </div>
    <div class="modal-body">
      <p>Some text in the modal.</p>
    </div>
    <div class="modal-footer">
      <button type="button" class="btn btn-default" data- 
     dismiss="modal">Close</button>
    </div>
  </div>

</div>

And the function javascriptthat I am using is the following:

function myFunction() {
var option_value = document.getElementById("numbers").value;
if (option_value == "3") {
    alert("Hai !");
 }
}

The problem is that when choosing option 3 it shows me a alert, what I am looking for is to show a modal made with boostrap, I tried to put a instead of alerta $('#myModal').modal('show');but when choosing nothing came out, how else could I do it?

Thanks.

Hello , I am trying to bring the last data of my table but when I return I see that it brings it as an array type and it does not enter the validation, how could I solve this?

I attach the code:

$credentials=tbl_usuario::select('rol')->orderBy('usu_id')->take(1)->get();

    //$credentials=DB::select('select rol from tbl_usuario order by usu_id desc limit 1')->get();

    if ($credentials =='Lab Catálisis' or $credentials =='Lab Suelos' or $credentials =='Lab Biotecnología' or $credentials =='Lab Análisis petrofísicos') {
        $lab = new tbl_lab();
        $lab->lab_ceco = $request->ceco;
        $lab->lab_direccion = $request->direccion;
        $lab->lab_lider = $request->lider;
        $lab->lab_usu_id = tbl_usuario::max('usu_id');
        $lab->save();
        return view('login');
    }
    return $credentials;

This is what the $credentials variable returns:

[{"rol":"Lab Cat\u00e1lisis"}]

I need to get the rows/fields from a file that I upload excelto my Laravel project, I made the code to load my database directly with laravel excel 3.1, but what I need is to get the data and then enter it myself through a insertin the part of the values. In addition, excelthere are several data (several rows). So how could that be made insert?

I add the code of my controller (import):

 use Maatwebsite\Excel\Concerns\ToModel;

class InstrumentosImport implements ToModel
 {

public function model(array $row)
{
    return new tbl_instrumentos([
        'ins_codigo'   => $row[0],
        'ins_observacionInicial'   => $row[1],
        'ins_claseOexactitud'    => $row[2],
    ]);
 }
}

Additionally I add the code of my main controller:

class TestController extends Controller
{

public function importExportView()
{
   $data=DB::table('tbl_instrumentos')->orderBy('ins_id','DESC')
            ->get();
    return view('importar',compact('data'));
}

/**
* @return \Illuminate\Support\Collection
*/
public function exportExcel($type) 
{
    return Excel::download(new InstrumentosExport, 'instrumentos.'.$type);
}

/**
* @return \Illuminate\Support\Collection
*/
public function importExcel(Request $request) 
{
   $this->validate($request, [
  'select_file'  => 'required|mimes:xls,xlsx'
 ]);
    Excel::import(new InstrumentosImport,$request->import_file);

     return back()->with('success', 'Datos Excel Importados Satisfactoriamente.');
}

The import_file that I have in my controller (import) comes from my view through an input which is the following:

    <input type="file" name="import_file" />

Hello, I am trying to enter a data to a field of my database in Laravel, the problem is that I get Array to string conversion , the code is as follows:

$credentials='Lab Catálisis';
    if ($credentials =='Lab Catálisis') {
        $lab = new tbl_lab();
        $lab->lab_ceco = $request->ceco;
        $lab->lab_direccion = $request->direccion;
        $lab->lab_lider = $request->lider;
        $lab->lab_usu_id = DB::select("SELECT max(usu_id) FROM tbl_usuario");
        $lab->save();
        return view('login');
    }

The DB brings me the data as an array, how could I convert that array that the query brings me to an integer to be able to enter it into my field.

Thanks.

Hello, I am trying to enter data into two different tables through Laravel, the data comes from a view, the problem is that I get the following error

The GET method is not supported for this route. Supported methods: POST.

Apparently according to what I have asked it is due to the request but I am not sure, the first part that enters the data to the users table works correctly, apparently the problem comes in the if. Attached is the code of my controller:

public function RegistroCliente(Request $request)
{
    $validacion = Validator::make($request->all(),
    [

        'usuario' => 'required|max:50',
        'password' => 'required|min:6',
        'rol'=>'required',
        'cedula' => 'max:12',
        'celular'=> 'max:10',
        'ceco'=> '',
        'direccion' =>'',
        'lider' =>'',
        'lab_usu_id'=>''
    ]);

    if($validacion->fails())
    {
        return redirect('/registrar')
            ->withInput()
            ->withErrors($validacion);
    }

    $user=new tbl_usuario();
    $user->usuario=$request->usuario;
    $user->password=bcrypt($request->password);
    $user->rol=$request->rol;
    $user->cedula=$request->cedula;
    $user->celular=$request->celular;
    $user->save();



    //$credentials =DB::select("SELECT max(rol) FROM tbl_usuario");
    $credentials='Lab Catálisis';
    if ($credentials=='Lab Catálisis') {
        $lab=new tbl_lab();
        $lab->ceco=$request->ceco;
        $lab->direccion=$request->direccion;
        $lab->lider=$request->lider;
        $lab->lab_usu_id=DB::select("SELECT max(usu_id) FROM tbl_usuario");
        $lab->save();
        return view('login');
    }

}

The view where I send the data is the following:

<form class="register-form" method="POST" action="{{ route('registro') }}" >
      {{ csrf_field() }}
      <div class="form-group">
        <label>Usuario</label>
        <input type="text" class="form-control" name="usuario" placeholder="Ingrese el usuario">
      </div>
      <div class="form-group">
        <label>Contraseña</label>
        <input type="password" name="password" class="form-control" placeholder="Ingrese la contraseña">
      </div>
      <div class="form-group">
        <label for="exampleFormControlSelect1" onclick="comprobar()">Seleccione el Rol
        <select class="form-control" id="rol" name="rol" required>
          <option value="1" >----</option>
          <option value="2">Lab Metrología</option>
          <option value="3">Lab Suelos</option>
          <option value="4">Lab Biotecnología</option>
          <option value="5">Lab Análisis petrofísicos</option>
          <option >Lab Catálisis</option>
        </select>
      </label>


      <p id="datos" style="visibility: hidden;">
        <label>

          <label>CECO</label>
          <input type="text" class="form-control" name="ceco" placeholder="Ingrese el codigo ceco">

          <label>Direccion</label>
          <input type="text" class="form-control" name="direccion" placeholder="Ingrese la dirección">

          <label>Lider</label>
          <input type="text" class="form-control" name="lider" placeholder="Ingrese el nombre del lider">

        </label>
      </p>
      </div>
      <div class="form-check">
        <button type="submit" class="btn btn-register float-right">Registrar</button>
      </div>
    </form>

And the path is as follows:

Route::post('/registrar','registroController@RegistroCliente')->name('registro');

Thanks.

Hello, I find myself making a record in Laravel but when I click on a button to open the record view, I get the following error:

The GET method is not supported for this route. Supported methods: POST.

The view code is as follows:

            <form class="register-form" action="{{ url('/registrar') }}" method="POST">
          {{ csrf_field() }}
          <div class="form-group">
            <label for="exampleInputUsername" class="text-uppercase">Usuario</label>
            <input type="text" class="form-control" name="usuario" placeholder="Ingrese el usuario">
          <div class="form-group">
            <label for="exampleInputPassword1" class="text-uppercase">Contraseña</label>
            <input type="password" name="password" class="form-control" placeholder="Ingrese la contraseña">
          </div>
    <div class="form-check">
    <button type="submit" class="btn btn-register float-right">Registrar</button>
  </div>

</form>

I have the route in the web.php like this

Route::post('/registrar','registroController@RegistroCliente')->name('registro');

And the code in my controller is as follows:

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use Illuminate\Support\Facades\Auth;
use App\tbl_usuario;

class loginController extends Controller
{
    public function RegistroCliente(Request $request)
    {
        $validacion = Validator::make($request->all(),
        [
            'usuario' => 'required|max:50',
            'password' => 'required|min:6'
        ]);

        if($validacion->fails())
        {
            return redirect('/#register')
                ->withInput()
                ->withErrors($validacion);
        }

        $user=new tbl_usuario();
        $user->usuario=$request->usuario;
        $user->password=$request->password;
    }

}

I find myself doing a login from scratch in Laravel, but when I enter it does not give me an error or anything like that, it redirects me to the same login, the code of the form in my view is as follows:

<form method="POST" action="{{ url('/verificar') }}">
              {{ csrf_field() }}
              <div class="form-group">
                 <label>Usuario</label>
                 <input name="usuario" type="text" class="form-control" placeholder="Ingrese su Usuario">
              </div>
              <div class="form-group">
                 <label>Contraseña</label>
                 <input type="password" name="password"class="form-control" placeholder="Ingrese su Contraseña">
              </div>
              <button type="submit" class="btn btn-black">Ingresar</button>
             <button type="submit" class="btn btn-secondary" ><a style="color:#ffffff;"href="{{ route('registro') }}">Registrar</a></button>
           </form>

The route with the post method is:

Route::post('/verificar','loginController@login');

and in my controller I have a function which add the following code:

public function login()
{
    $credenciales=$this->Validate(request(),
        [
            'usuario'=>'required|unique:tbl_usuario',
            'password'=>'required|min:6'
        ]);
    if (Auth::attempt($credenciales))
    {
        return view('welcome');
    }else{
        return back()
            ->withErrors(['usuario'=>trans('auth.failed')])
            ->withInput(request(['usuario']));
    }
}
