我有一個公式化與mutiples模型和標記錯誤的時刻看守信息多模型IntegrityError

我離開他們，標誌着我的錯誤，當我嘗試看守信息

後來我離開他們我的模型

class Cliente(models.Model): 
    nombre = models.CharField(max_length=50) 
    apellido_Materno = models.CharField(max_length=50) 
    apellido_Paterno = models.CharField(max_length=50) 
    puesto = models.CharField(max_length=50) 
    telefono = models.IntegerField(max_length=10, unique=True, validators=[RegexValidator(regex='^\d{10}$', message='Debe de se de 10 digitos', code='Invalid number')]) 
    mail = models.EmailField(max_length=75) 
    created = models.DateTimeField(auto_now_add=True) 

    def __unicode__(self): 
     return u'%s' % self.nombre 

class Empresa(models.Model): 
    nombreEmpresa = models.CharField(max_length=100) 
    calle = models.CharField(max_length=100) 
    numero_Exterior = models.IntegerField() 
    numero_Interior = models.IntegerField(null=True) 
    Colonia = models.ForeignKey(Colonia) 
    delegacion = models.ForeignKey(Delegacion) 
    rutas = models.ManyToManyField(Ruta) 
    cliente = models.ForeignKey(Cliente) 
    categoria = models.ForeignKey(Categoria) 
    subcategoria1 = models.ForeignKey(Subcategoria1) 
    subcategoria2 = models.ForeignKey(Subcategoria2) 
    subcategoria3 = models.ForeignKey(Subcategoria3) 
    position = GeopositionField() 
    created = models.DateTimeField(auto_now_add=True)

我views.py

def register_cliente(request): 
    if request.method == "POST": 
     form_a = CreateCliente(request.POST, prefix="cli") 
     form_b = CreateEmpresa(request.POST, prefix="emp") 
     if form_a and form_b.is_valid(): 
      cliente = form_a.save(commit = False) 
      cliente.empresa = form_b.save() 
      return HttpResponse('registro Realisado') 
     else: 
      form_a = CreateCliente(prefix="cli") 
      form_b = CreateEmpresa(prefix="emp") 
     context = {} 
     context.update(csrf(request)) 
     context['form_a'] = form_a 
     context['form_b'] = form_b 
     #Pass the context to a template 
     return render_to_response('registercliente.html', context) 
    else: 
     form_a = CreateCliente(prefix="cli") 
     form_b = CreateEmpresa(prefix="emp") 
     return render(request, 'registercliente.html', {'form_a': form_a,'form_b': form_b})

我forms.py

class CreateCliente(ModelForm): 

    class Meta: 
     model = Cliente 
     fields = ('nombre','apellido_Paterno','apellido_Materno','puesto','telefono','mail') 

class CreateEmpresa(ModelForm): 

    class Meta: 
     model = Empresa 
     fields = ('nombreEmpresa','calle','numero_Exterior','numero_Interior','Colonia','delegacion')

我的HTML

{% extends 'base.html' %} 
{% block content %} 
<form action="." method="POST"> 
    {% csrf_token %} 
    {{ form_a.as_p }} 
    {{ form_b.as_p }} 
<input type="submit" value="Guardar"> 
</form> 
{% endblock %}

回溯，請。 – skzryzg

更改您要保存表單的方式，如下

if form_a and form_b.is_valid(): 

     cliente = form_a.save() 
     empresa = form_b.save(commit=False) 
     empresa.cliente = cliente 
     empresa.save() 
     return HttpResponse('registro Realisado')

empresa.cliente不能爲空，所以當你正在做form_b.save()該字段爲空，因此你得到錯誤。
