从views.py导入无法从应用程序工作

Question

I'm working with django and I'm trying to get a simple app functional.

The app is supposed to deliver a simple 'Hello world'-view but my_app/urls.py fails to import methods from my_app/views.py .

My app is named SocialUrl

Here is 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),
)

Here is my-app/urls.py

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

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

Here is my-app/views.py

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

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

Note:- that the testlines in my-project/urls.py works correctly.

My folder structure looks like this:

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

I've added this in my-project/settings.py

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

I get the following error:

    Environment:

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

I have tried various combinations of the from . import views from . import views line in my-app/urls.py eg. from views import test

Edit:

still disfunctional my-app/urls.py

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

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

Answer 1

The problem is that you really have this line in your app urls.py :

url(r'^$', test)

The error says that test is not defined. Just define (import) it:

from views import test

Answer 2

I think this may cause the error:

url(r'^/su/', include('SocialUrl.urls')),

remove the leading slash and you will only have:

url(r'^su/', include('SocialUrl.urls')),

Let me know if this worked for you

Answer 3

I'm not sure if this is the issue - but generally I follow this pattern for my app level url files.

Main project urls.py file

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

urlpatterns = patterns('apps.main.views',
    url(r'', include('apps.main.urls')),
)

App level urls.py file

from django.conf.urls import patterns, url

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

Note that you should use urlpatterns += or urlpatterns = depending on whether it is defined earlier.
