django cms apphook 错误

Question

我正在学习 django-cms。我尝试制作非常成功的自定义插件，但是当我尝试将我的自定义插件挂钩到 apphook 时，它给了我一个错误，说，

没有名为 urls 的模块 .

我按照 django cms 站点文档中给出的教程，创建了 cms_app.py 文件。目前，我的应用程序目录包含为 django cms 制作自定义插件所需的所有文件，以及 cms_app.py 的附加文件。

url 设置有问题还是我需要在我的应用目录中创建一个新的 urls.py 文件？

我的 cms_app.py 和教程中给出的完全一样。

我使用命令创建了一个名为 myproject 的项目 -

python django-admin.py 启动项目 我的项目

参考 cms 的教程后，我创建了一个名为 first 的插件，使用基本命令

python manage.py 先启动app

现在插件运行良好，在尝试使用 apphook 之前的目录结构是，

first/
    __init__.py
    cms_plugins.py
    models.py
    tests.py
    views.py

现在尝试在 apphook 中挂钩应用后，目录结构为：

first/
    __init__.py
    cms_app.py
    cms_plugins.py
    models.py
    tests.py
    views.py

我的cms_app.py如下：

from cms.app_base import CMSApp
from cms.apphook_pool import apphook_pool
from django.utils.translation import ugettext_lazy as _

class FirstApp(CMSApp):
    name = _("First App") # give your app a name, this is required
    urls = ["first.urls"] # link your app to url configuration(s)

apphook_pool.register(FirstApp) # register your app

我的项目文件夹中有一个urls.py文件，内容如下：

from django.conf.urls.defaults import *
from django.contrib import admin
from django.conf import settings


# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'myproject.views.home', name='home'),
    # url(r'^myproject/', include('myproject.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
        url(r'^admin/', include(admin.site.urls)),
    url(r'^', include('cms.urls')),

)

if settings.DEBUG:
    urlpatterns = patterns('',
        (r'^' + settings.MEDIA_URL.lstrip('/'), include('appmedia.urls')),
    ) + urlpatterns

我已经按照教程中的说明重新启动了服务器，但没有成功。 关于我的简单应用有什么问题的任何想法？！

编辑 - 1 我的意见文件如下：

from django.http import HttpResponse

def index(request):
    “””Generate the context for the main summary page”””
    return render_to_response(‘first/first.html’)

编辑 - 2 我已将第一个应用程序文件夹中的 urls.py 更改为：

from django.conf.urls.defaults import *
from django.contrib import admin
from django.conf import settings


# Uncomment the next two lines to enable the admin:
# from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
    # Examples:
    # url(r'^$', 'myproject.views.home', name='home'),
    # url(r'^myproject/', include('myproject.foo.urls')),

    # Uncomment the admin/doc line below to enable admin documentation:
    # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

    # Uncomment the next line to enable the admin:
        #url(r'^admin/', include(admin.site.urls)),
    url(r'^first/$', include('first.views.index')),

)

if settings.DEBUG:
    urlpatterns = patterns('',
        (r'^' + settings.MEDIA_URL.lstrip('/'), include('appmedia.urls')),
    ) + urlpatterns

但现在我收到此错误：

我已经编辑了网址和视图，但现在我收到了这个错误。

Answer 1

您没有包含“第一个”应用的 URL 的 first.urls 模块。在您的文件 first/models.py 旁边，创建一个文件 first/urls.py，其中包含“第一个”应用的 URL 模式。

对于您在问题中给出的观点，urls.py 应该如下所示：

from django.conf.urls.defaults import *
from first.views import index

urlpatterns = patterns('',
    url(r'^$', index),
)

另请注意，在您的观点中，您使用了非标准引号字符，它应该如下所示：

from django.http import HttpResponse

def index(request):
    """Generate the context for the main summary page"""
    return render_to_response("first/first.html")
