Django, AttributeError: 'module' object has no attribute
Question: Excuse me for my english. I start Django Project (I'm beginner on Django &
Python) with Django Rest Framework.

My project :

    
    
    # tree -I 'env'

My project (Hugs) urls.py

    
    
    from django.conf.urls import url, include
    from django.contrib import admin
    
    urlpatterns = [
        url(r'^admin/', admin.site.urls),
        url(r'^', include('api.urls')),
    ]
    

My app (api) urls.py :

    
    
    from django.conf.urls import url
    from . import views
    
    urlpatterns = ['',
        url(r'^snippets/$', views.snippet_list),
        url(r'^snippets/(?P<pk>[0-9]+)/$', views.snippet_detail),
    ]
    

My app views (api/views.py) :

    
    
    from django.shortcuts import render
    
    # Create your views here.
    
    from django.http import HttpResponse
    from django.views.decorators.csrf import csrf_exempt
    from rest_framework.renderers import JSONRenderer
    from rest_framework.parsers import JSONParser
    from api.models import Snippet
    from api.serializers import SnippetSerializer
    
    class JSONResponse(HttpResponse):
        """
        An HttpResponse that renders its content into JSON. 
        """
        def __init__(self, data, **kwargs):
            content = JSONRenderer().render(data)
            kwargs['content_type'] = 'application/json'
            super(JSONResponse, self).__init__(content, **kwargs)
    
        @csrf_exempt
        def snippet_list(request):
            ....
            ....
    

Error :

    
    
    AttributeError: 'module' object has no attribute 'snippet_list'

Thanking you in advance ! :)

Good day !


Answer: `snippet_list` should not be defined inside JSONResponse: unindent it.

Note that Django has provided a JSONResponse class since 1.8, there is no need
to define your own.
