Django，AttributeError：'模塊'對象沒有屬性

Question

對不起，我的英語。我用Django Rest Framework啓動Django Project（我是Django & Python的初學者）。

我的項目：

我的項目（擁抱）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')), 
] 

我的應用程序（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), 
] 

我的應用程序的意見（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): 
     .... 
     .... 

錯誤：

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

調用堆棧：

# ./manage.py runserver

請多關照！ :)

美好的一天！

Answer 1

snippet_list不應該在JSONResponse裏面定義：unindent它。

請注意，自1.8以來，Django提供了一個JSONResponse類，不需要定義自己的。
