我有一个公式与mutiples模型，并标记错误到当前保护信息

当我试图保护信息时，我留下了标记我的错误

后来我给他们留下了我的模特

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)

my 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})

my 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 %}

Answer 1

更改保存表单的方式，如下所示

    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不应为null，因此当您执行form_b.save()时，该字段为空，因此您收到错误。
