python - Django，属性错误: 'module' object has no attribute

Question

请原谅我的英语。我使用 Django Rest Framework 启动 Django 项目(我是 Django 和 Python 的初学者)。

我的项目:

# tree -I 'env'

我的项目(拥抱)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')),
]

我的应用程序(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),
]

我的应用程序 View (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):
        ....
        ....

错误:

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

调用堆栈:

提前感谢您! :)

美好的一天!

snippet_list 不应在 JSONResponse 中定义:取消缩进。

请注意，Django 从 1.8 开始就提供了 JSONResponse 类，无需定义自己的类。
