python - 从views.py导入不适用于应用程序

Question

我正在使用 django，我正在尝试让一个简单的应用程序发挥作用。

该应用程序应该提供一个简单的“Hello world” View ，但是 my_app/urls.py无法从 my_app/views.py 导入方法.

我的应用名为SocialUrl

这里是my-project/urls.py 。

from django.conf.urls import patterns, include, url
# from SocialUrl.views import test

from django.contrib import admin
admin.autodiscover()

    urlpatterns = patterns('',
    url(r'^admin/', include(admin.site.urls)),
    url(r'^/su/', include('SocialUrl.urls')),
    # url(r'^$', test),
)

这里是my-app/urls.py

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

urlpatterns = patterns('',
    # ex: /polls/
    url(r'^test$', views.test()),
)

这里是my-app/views.py

from django.shortcuts import render
from django.template import RequestContext

def test(request):
    return render(request, 'test.html', RequestContext(request, {}))

注意:- my-project/urls.py 中的测试线工作正常。

我的文件夹结构如下所示:

my-project
|- my-project
|- my-app

我已将其添加到my-project/settings.py中

TEMPLATE_DIRS = (
    os.path.join(os.path.dirname(__file__), 'templates').replace('\\', '/'),
    os.path.join(BASE_DIR, 'SocialUrl', 'templates').replace('\\', '/'),
)

我收到以下错误:

    Exception Type: NameError at /
    Exception Value: name 'test' is not defined

我尝试过 from . import views 的各种组合线路 my-app/urls.py 例如。 from views import test

编辑:

仍然无法正常工作my-app/urls.py

from django.conf.urls import patterns, url
from views import test

urlpatterns = patterns('',
    # ex: /polls/
    url(r'^$', test),
)

Answer 1

问题是你的应用程序中确实有这一行urls.py:

url(r'^$', test)

该错误表明 test 未定义。只需定义(导入)它即可:

from views import test
