Django - 在/ blog的importError。 （没有名为urls的模块）

Question

在学习Django教程（本书是使用Django的Python Web开发）时，我一直遇到导入错误。

我在这里和Google一起寻找解决方案，但我找不到一个有效的解决方案。

我的错误是ImportError at /blog. No module named urls.

我正在使用 django 1.5.1 。

我的文件是结构 -

 - mysite
     manage.py
     - blog
        __init__.py
        models.py
        tests.py
        urls.py
        views.py
        - templates
            archive.html
     - mysite
        __init__.py
        settings.py
        urls.py
        wsgi.py

mysite的/博客/ urls.py

from django.conf.urls.defaults import patterns, include, url
from mysite.blog.views import archive

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

mysite的/博客/ view.py

from django.template import loader, Context
from django.http import HttpResponse
from mysite.blog.models import BlogPost

def archive(requset):
    posts = BlogPost.objects.all()
    t = loader.get_template("archive.html")
    c = context({ 'posts': posts })
    return HttpResponse(t.render(c))

mysite的/ mysite的/ urls.py

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

admin.autodiscover()

urlpatterns = patterns('',
       url(r'^admin/', include(admin.site.urls)),
       url(r'^blog/', include('mysite.blog.urls')),
      # url(r'^admin/doc/', include('django.contrib.admindocs.urls')),

)

setting.py

TEMPLATE_LOADERS = (
    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',
#     'django.template.loaders.eggs.Loader',
)
INSTALLED_APPS = (
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.sites',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    # Uncomment the next line to enable the admin:
    'django.contrib.admin',
    # Uncomment the next line to enable admin documentation:
    'django.contrib.admindocs',
    'blog',
)

Answer 1

我认为你必须改变这一行：

url(r'^blog/', include('mysite.blog.urls')),

到此：

url(r'^blog/', include('blog.urls')),

希望它有所帮助！

Answer 2

我的解决方案在这里：

mysite的/博客/ urls.py

from mysite.blog.views import archive 

到

from blog.views import archive

mysite的/博客/ view.py

from mysite.blog.models import BlogPost 

到

from blog.models import BlogPost

mysite的/ mysite的/ urls.py

url(r'^blog/', include('mysite.blog.urls')), 

到

url(r'^blog/', include('blog.urls')),

我建议你在settings.py中设置DEBUG为true。当有错误时，它可以告诉你应用程序停止的地方。在这种情况下，你只需要跳到这个地方。调试会更好。

Answer 3

将此文件更改为mysite / blog / urls.py     来自django.conf.urls.defaults导入模式，include，url
至 来自django.conf.urls导入模式，include，url

Answer 4

我遇到了同样的问题，但我做的却与@Haimei做的相反

mysite的/博客/ urls.py     来自blog.views import archive将其更改为

from mysite.blog.views import archive

它有效。

还要确保删除.defaults     来自django.conf.urls.defaults导入模式，include，url
