Tag: keyword

Soy muy nuevo en desarrollo y mas aún en Django.
He creado una tabla persona, (matricula, nombre e email) y una tabla peticionario (jefe, peticionario, resp_servicio y resp_aplicacion cada uno de estos es una persona a través de clave foranea).Como los dos últimos son opcionales (el rs y ra) quiero trabajar con FormSet.
El caso es que al cargar este formset de la clase persona me da el siguiente error “Persona() got an unexpected keyword argument ‘auto_id'”.
He buscado pero no encuentro una solución que entienda (repito, estoy muy perdido), el código es el siguiente:
models.py:`

from django.db import models
from recogidaDatos import choices


class Persona(models.Model):
    matricula = models.CharField(max_length=7, verbose_name='Matrícula', unique=True)
    nombre = models.CharField(max_length=100, verbose_name='Nombre')
    email = models.EmailField(max_length=150,verbose_name='Email')    

    class Meta:
        verbose_name = 'persona'
        verbose_name_plural = 'personas'
        ordering = ('nombre')

    def __str__(self):
        return self.nombre

class Solicitantes(models.Model):
    jefe = models.ForeignKey(Persona, related_name='jefe', verbose_name="Jefe", on_delete=models.PROTECT)
    peticionario = models.ForeignKey(Persona, related_name='peticionario', verbose_name="Jefe", on_delete=models.PROTECT)
    ra = models.ForeignKey(Persona, related_name='ra', on_delete=models.PROTECT, null=True, blank=True, verbose_name="Responsable aplicación")
    rs = models.ForeignKey(Persona, related_name='rs', on_delete=models.PROTECT, null=True, blank=True, verbose_name="Responsable Servicio")

    class Meta:
        verbose_name = 'Solicitantes'
        verbose_name_plural = 'Solicitantes'
        ordering = ('jefe')

    def __str__(self):
        return self.jefe + self.peticionario + self.ra + self.rs`

forms.py:

    from django import forms
from .choices import *
from .models import *


class FormPersona(forms.ModelForm):

    class Meta:
        model = Persona
        exclude = ()

views.py:

from django.shortcuts import render
from django.forms import formset_factory
from .models import *
from .forms import *

# Create your views here.

def recogidaDatos(request):

    PersonasFormset = formset_factory(Persona, extra=4 ,max_num=4)
    personas = PersonasFormset()



    if request.method =='POST':
        personas = PersonasFormset(data=request.POST)
        if  personas.is_valid():   
            pass         
    return render(request,'recogidaDatos/formulario2.html',{'personas':personas})

template.py:

<form action="" method="POST">
  {% csrf_token %}

    {{personas.management_form}}
    <table>
        {% for persona in personas.forms %}
            {{ persona }}
        {% endfor %}
    </table>


    <input name="" id="" class="btn btn-primary" type="submit" value="Enviar">
  </form>
