'function' object has no attribute 'as_view'

Question

I am trying to use class based views, and get a strange error. The way I’m using the view seems to be the normal way:

ingredients/models.py:

from django.db import models
from django.utils import timezone


class Ingredient(models.Model):
    name        = models.CharField(max_length=255)
    description = models.TextField()

    def get_prices():
        purchases   = self.purchase_set.all()
        prices      = [purchase.price for purchase in purchases]

ingredients/views.py:

from django.shortcuts           import render, render_to_response, redirect
from django.http                import HttpResponse, HttpResponseRedirect
from django.views.generic.edit  import CreateView
from .models                    import Ingredient, Purchase

def IngredientCreateView(CreateView):
    model = Ingredient
    fields = ['all']

ingredients/urls.py:

from django.conf.urls import patterns, include, url

from ingredients.views import IngredientCreateView

urlpatterns = patterns('',            
    url(r'^new_ingredient$',          IngredientCreateView.as_view(),             name='new-ingredient'),
)

I get

AttributeError at /ingredients/new_ingredient
'function' object has no attribute 'as_view'

I am on django 1.8.5. Why won’t this view work? Thank you

Answer 1

IngredientCreateView should be a class.
So your views.py replace:

def IngredientCreateView(CreateView):

with:

class IngredientCreateView(CreateView):

Answer 2

IngredientCreateView is a function, not a class.

The following line

def IngredientCreateView(CreateView):

should be replace with

class IngredientCreateView(CreateView):

Answer 3

In my case, the problem was that I tried to use a @decorator on the class-based view as if it was a function-based view, instead of @decorating the class correctly.

EDIT: From the linked page, here is a way to apply @login_required to a class-based view:

from django.contrib.auth.decorators import login_required
from django.utils.decorators import method_decorator

@method_decorator(login_required, name='dispatch')
class ProtectedView(TemplateView):

Answer 4

In addition to what is already said here, Check the file name and class name if it is same then you might have to import the class properly.

File name /api/A.py

class A:
//some methods

In your main class

//App main class
from api.A import A

I faced the same problem but this solution worked for me..

in views.py file in viewclass you can use viewsets instead of CreateView

            from rest_framework import viewsets
            class YourClassView(viewsets.ModelViewSet):

in urls.py file you can use this routing pattern

          from django.conf.urls import url
          from rest_framework import routers

          router = routers.DefaultRouter()
          router.register('books',YourClassView)

          urlpatterns = [
               path('', include(router.urls)),
               path('admin/', admin.site.urls)
            ]
