django-导入错误：没有名为视图的模块

David J. 发表于 Dev

戴维·J。

我一直在绞尽脑汁，无法弄清楚为什么导入“视图”时应该出现导入错误。访问索引页面时收到以下消息：

"
Request Method: GET
Request URL:    http://127.0.0.1:8000/moments/
Django Version: 1.6.1
Exception Type: ImportError
Exception Value:    
No module named views
Exception Location: C:\Python27\lib\site-packages\django\utils\importlib.py in import_module, line 40
"

这是我的urls.py

from django.conf.urls import patterns, url

from moments_app import views

urlpatterns = patterns('',
    url(r'^$', "views.index", name='index'),
    url(r'^$', "views.choose_dataset", name='choose'),
    url(r'^get_moments/', "views.get_moments", name='get_moments'),
    url(r'^learn/$', "views.learn", name='learn'),
    url(r'^(?P<moment_id>\d+)/$', "views.detail", name='detail'),

)

我的moments_app文件夹中显然有一个名为views的模块。另外，moments_app在我的路上。是否有人对造成这种情况有任何想法？

您为路由名称添加了相对的模块名称。使用绝对名称：

urlpatterns = patterns('',
    url(r'^$', "moments_app.views.index", name='index'),
    url(r'^$', "moments_app.views.choose_dataset", name='choose'),
    url(r'^get_moments/', "moments_app.views.get_moments", name='get_moments'),
    url(r'^learn/$', "moments_app.views.learn", name='learn'),
    url(r'^(?P<moment_id>\d+)/$', "moments_app.views.detail", name='detail'),
)

或更妙的是，使用第一个参数指定完整的模块路径：

urlpatterns = patterns('moments_app.views',
    url(r'^$', "index", name='index'),
    url(r'^$', "choose_dataset", name='choose'),
    url(r'^get_moments/', "get_moments", name='get_moments'),
    url(r'^learn/$', "views.learn", name='learn'),
    url(r'^(?P<moment_id>\d+)/$', "detail", name='detail'),
)

尽管也可以将两者结合使用：

urlpatterns = patterns('moments_app',
    url(r'^$', "views.index", name='index'),
    url(r'^$', "views.choose_dataset", name='choose'),
    url(r'^get_moments/', "views.get_moments", name='get_moments'),
    url(r'^learn/$', "views.learn", name='learn'),
    url(r'^(?P<moment_id>\d+)/$', "views.detail", name='detail'),
)
