Diego's questions

I want to be able to search a field for an artist/band from the lastfm api using flask and request. And I have problems in the syntax and/or logic but I don't know how to correct them.

from flask import Flask
from flask import render_template
from flask import request
import requests
import json

app = Flask(__name__)
app.debug = True

@app.route('/')
@app.route('/vista', methods=['GET', 'POST'])
def homepage():
  params = {
    'api_key': '5c1016ab26ab5b2f6ad21c3d873785bc',
    'format' : 'json',
    'artist': request.args.get('artista')
  }
  r = requests.get(
      'http://ws.audioscrobbler.com/2.0/?method=artist.gettopalbums',
      params=params)

  return render_template('vista.html',
               albums=r.json()['topalbums']['album'])


if __name__ == "__main__":
    app.run (host = '127.0.0.1', port = 5000, threaded=True)





   <form action="/buscador.py">
      Artista: <input type="search" name="artista"><br>
      <input type="submit" value="buscar">
    </form>

I am testing the rest api of these two entities in a postman that gives me 404, eclipse compiles the project well, so I guess it is something wrong in the logic of my service or controller, I do not know which of the I am wrong or if in both classes.

Below I leave the tables an institution has many institutes

@Entity(name="Instituto")
@Table(name="instituto")
public class InstitutoEntity {

    @Id
    @GeneratedValue (strategy = GenerationType.IDENTITY)
    @Column (name = "ID", nullable = false, updatable = false)
    private int id;

    @ManyToOne
    @JoinColumn(name = "ID_INSTITUCION", nullable = false)
    private InstitucionEntity institucion;

    @Column (name = "NOMBRE", length = 30, nullable = false)
    private String nombre;

    @Column (name = "COLOR_HEXA", length = 30, nullable = false)
    private String color_hexa;


    public InstitutoEntity() {
        super();
        // TODO Auto-generated constructor stub
    }


    public InstitutoEntity(int id, InstitucionEntity institucion, String nombre, String color_hexa) {
        this.id = id;
        this.institucion = institucion;
        this.nombre = nombre;
        this.color_hexa = color_hexa;
    }


    public int getId() {
        return id;
    }


    public void setId(int id) {
        this.id = id;
    }


    public InstitucionEntity getInstitucion() {
        return institucion;
    }


    public void setInstitucion(InstitucionEntity institucion) {
        this.institucion = institucion;
    }


    public String getNombre() {
        return nombre;
    }


    public void setNombre(String nombre) {
        this.nombre = nombre;
    }


    public String getColor_hexa() {
        return color_hexa;
    }


    public void setColor_hexa(String color_hexa) {
        this.color_hexa = color_hexa;
    }


    @Override
    public String toString() {
        return "InstitutoEntity {"+ 
                "id=" + id + ","
                + " institucion=" + institucion + ", "

I have the following files in my spring boot project. And I would like to use the tables and be able to consume that data with my restful api. I have the create-drop but that creates and deletes every time I run the application and the tables are empty because I don't insert anything during the create-drop. But I already have data in the tables and I can't get it, the get with postman brings me a 200 but it's empty. My mistake is in the logic of the properties.

In my example I want to access all the albums that coldplay has. this is the json. I understand that with the requests library I transform it into a dictionary but I cannot access the albums but it returns the value of each position in the topalbums element https://jsoneditoronline.org/?id=c8de55785bbb400cb34c62d519e2962d

import requests
import json

r = requests.get('http://ws.audioscrobbler.com/2.0/?method=artist.gettopalbums&artist=coldplay&api_key=a31007b9178e35854f9fa22039cb7362&format=json')
musica_dict = json.loads(r.text)

print type(musica_dict)

for item in musica_dict:
    for album in item:
        print album

hello when I import this library in android studio import com.google.gson.Gson; It tells me that cannot resolve symbol gson I looked for it with the sdk manage in the google part and I can't find it, what could it be? I leave the build.gradle, I don't know if it has to do with the sdk.

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

    applicationId "aplicacionesmoviles.tp"

my question is how to know the location of a website, if it is hosted in Europe or America for example? Or is there a website where I can see where certain pages are hosted? It is because I have a PRTG sensor that analyzes the ping (in ms) of a website and I wanted to compare them with each other. Sorry I didn't know what tag to use and it's not about specific code either.

I have a question why this method is never executed? There is no syntax error and it is correctly invoked but I can't understand why it never uses it. the "public void signIn" method

Hello, I have this problem in all my projects in android studio and I tried with "clear project" and with Tools" -> "Android" -> "Sync Project with Gradle Files". And the problem continues, what other solution could you suggest me for favour.

android.gradle(module)

android {
compileSdkVersion 21
buildToolsVersion '21.1.2'

defaultConfig {
    applicationId "com.example.diego.tpfinal"
    minSdkVersion 9
    targetSdkVersion 23
    versionCode 1
    versionName "1.0"

android.gradle(project)

dependencies {
    classpath 'com.android.tools.build:gradle:2.1.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the [![Consola de android studio][1]][1]individual module build.gradle files
}

Updated---- build.gradle(module)

Solution: I fixed my problem with the following video and with Elena's comments previously. https://www.youtube.com/watch?v=pw4jKsOU7go

I wanted to know how to send mails with javascript and that inside the mail I have a subject and a body to be able to write.

My question is how to add inputs to the function, I know it would be something like this:

 $('#input1').val()

To the Jquery function that is the following

$('#element').click(function(){
    $(location).attr('href', 'mailto:?subject='
                         + encodeURIComponent("This is my subject")
                         + "&body=" 
                         + encodeURIComponent("This is my body")
    );
});

I have a form that when submitted calls a function, but doesn't call the valida_envia().

I have the scripts in different files, I call the function valida_envia()that is located in a file.js

This is my code (also available on JSFiddle )

function valida_envia() {

  //Definimos los caracteres permitidos en una dirección de correo electrónico
  var regexp = /^[0-9a-zA-Z._.-]+\@[0-9a-zA-Z._.-]+\.[0-9a-zA-Z]+$/;

  //Validamos un campo o área de texto, por ejemplo el campo nombre
  if (document.form.nombre.value.length == 0) {
    alert("Tiene que escribir su nombre");
    document.form.nombre.focus();
    return 0;
  }

  if ((regexp.test(document.form.email.value) == 0) || (document.form.email.value.length = 0)) {
    alert("Introduzca una dirección de email válida");
    document.form.email.focus();
    return 0;
  } else {
    var c_email = true;
  }

  document.form.submit();
}

<form name="Formulario" action="[email protected]" method="post" onsubmit="return valida_envia()">
  name:
  <br>
  <input type="text" id="nombre" name="nombre">
  <br> email:
  <br>
  <input type="text" id="email" name="email">

  <input type="submit" value="Enviar">

</form>

I do not find the error here because it does not send it to the email that is declared in action

function validar() {

  if (valor = document.getElementById("name").value;

    if (valor == null || valor.length == 0 || /^\s+$/.test(valor)) {
      return false;
    }) {

    alert('Error Debe ingresar texto y no espacios en blanco');
    return false;
  } else if (valor = document.getElementById("mail").value;
    if (!(/\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)/.test(valor))) {
      return false;
    }) {

    alert('[ERROR] El campo solicita un mail valido');
    return false;
  }
}

My problem is that it only shows me the first object of the json array but all of them appear in the browser console.

How could I show all those elements that the for returns in text?

<div id="success">
<div id="artistName"></div>

</div>
<script>
  $.ajax({ 
      type : 'POST', 
      url : 'http://ws.audioscrobbler.com/2.0/', 
      data :'method=artist.gettopalbums&'+'artist=cooldplay&'+api_key=57ee3318536b23ee81d6b27e36997cde&' + 'format=json',
      dataType : 'jsonp', 
      success : function(data) {
          for( var i=0 in data.topalbums.album) {
              $('#success #artistName').html(data.topalbums.album[i].name);
          } 
      }
    });
</script>

My method to access a json url is as follows and it works, but now I want to go through the json with a for and its ´.length´ but I couldn't.

The json from which I want to get the url is the following

http://www.jsoneditoronline.org/?id=74fa8799c027f3af0b2faf44ac1c9e47

<scriptsrc="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js</scr>
<div id="success">
<div id="artisturl"></div>
</div>

$.ajax({
   type : 'GET',
   url : 'https://api.spotify.com/v1/search',
   data : {'q':'coldplay',
   'type':'artist'
   },
   dataType : 'json',
   success : function(data) {
      $('#success #artisturl').html(data.artists.items[0].uri) ;
   },
}) ;

I wanted to know how to execute this method of the Lastfm api, it is simple, but I cannot execute it correctly. I know I'm accessing the label wrong

my attempt to use the method:

$.ajax({
        type : 'POST',
        url : 'http://ws.audioscrobbler.com/2.0/',
        data : 'method=artist.gettopalbums&' +
               'artist=cooldplay&' +
               'api_key=57ee3318536b23ee81d6b27e36997cde&' +
               'format=json',
        dataType : 'jsonp',
        success : function(data) {
            $('#success #artistName').html(data.topalbums.artist.name);
           
        },
        error : function(code, message){
            $('#error').html('Error Code: ' + code + ', Error Message: ' + message);            
        }
    });

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="success">
    <div id="artistName"></div>
    <div id="artistImage"></div>
    <div id="artistBio"></div>
</div>
<div id="error"></div>

What would be the correct way to execute the .getTopAlbums method?

Hi, I'm learning how JSON works with javascript consuming data from a weather api, but when I run it it shows me a blank browser. I took this example from here, I wanted to know what I'm doing wrong that I can't run the example, thanks. http://www.weblantropia.com/2015/05/19/weather-script-really-simple-with-php-or-javascript-and-json-update/
