django - 导入错误:没有模块命名视图

view

我一直绞尽脑汁,无法弄清楚为什么在导入'views'时会出现导入错误.当我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/$', "views.learn", name='learn'),
    url(r'^(?P\d+)/$', "views.detail", name='detail'),

)

我在moments_app文件夹中显然有一个名为views的模块.此外,moments_app在我的道路上.有没有人对可能导致这种情况的原因有任何想法？

两年更新:

在Django 1.8及更高版本patterns中,不推荐使用字符串视图和函数,从而使语法更简单,更可靠:

from django.conf.urls import url

from . import views

urlpatterns = [
    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'),
]

请注意,没有带有可调用语法的"相对"或"绝对"视图名称 - 如果导入views模块,则会获得其定义.我会避免导入单个视图函数,因为另一个导入很可能会定义一个碰撞名称.如果您不担心冲突并且不介意将您的应用名称放在文件中,则可以略微缩短网址:

from moments_app.views import index, choose_dataset, get_moments, learn, detail

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

您使用相对模块名称为路由名称添加前缀.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'),
)

或者更好的是,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'),
)

虽然也允许两者的组合:

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'),
)
