The view chilegaleria.views.AgregarTienda_View didn't return an HttpResponse object. It returned None instead

Question

I'm getting this error while using django 1.10.6:

ValueError at /AgregarTienda The view chilegaleria.views.AgregarTienda_View didn't return an HttpResponse object. It returned None instead.

This is my view

from django.shortcuts import render
from django.http import HttpResponse
from chilegaleria.forms import AgregarTiendaForm
# Create your views here.
def index(request):
    return render(request, 'chilegaleria/index.html')
def AgregarTienda_View(request):
    if request.method == 'POST':
        form = AgregarTiendaForm(request.POST)
    if form.is_valid():
            form.save()
            return redirect('chilegaleria:index')
    else:
            form = AgregarTiendaForm
            return render(request, 'chilegaleria/AgregarTienda.html', {'form':form})

Also when I add class Meta: model = DatosTienda to my forms.py file I get this error:

This is my forms.py file:

from django import forms
from chilegaleria.models import models
from django.forms import ModelForm
class AgregarTiendaForm(forms.ModelForm):


    class Meta:
        model = DatosTienda
        fields = [
        'nombre',
        'estado',
        'ciudad',
        'comuna',
        'direccion',
        ]
        labels = {
        'nombre': 'Nombre de la Tienda',
        'estado': 'Region',
        'ciudad': 'Ciudad',
        'comuna': 'Comuna',
        'direccion': 'Direccion',
        }
        widgets = {
        'nombre': forms.TextInput(attrs={'class':'form-control'}),
        'estado': forms.TextInput(attrs={'class':'form-control'}),
        'ciudad': forms.TextInput(attrs={'class':'form-control'}),
        'comuna': forms.TextInput(attrs={'class':'form-control'}),
        'direccion': forms.TextInput(attrs={'class':'form-control'}),
        }

File "C:\chilegalerias\chilegaleria\forms.py", line 8, in Meta Model = DatosTienda NameError: name 'DatosTienda' is not defined

Your log stack says that you must import the model DatosTienda in the file chilegaleria\forms.py

Also check your view, because if you get a GET request, your form is not being defined, so you will get a referenced before assignment an error.

The view chilegaleria.views.AgregarTienda_View didn't return an HttpResponse object. It returned None instead
