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

Question

在学习 Django 教程（本书是 Python Web Development with Django）时，我遇到了一个导入错误。

我已经在此处和 Google 上寻找解决方案，但找不到可行的解决方案。

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/blog/urls.py

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

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

mysite/blog/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/mysite/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')),

到这里：

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

希望对你有帮助！

Answer 2

更改此文件 mysite/blog/urls.py 从 django.conf.urls.defaults 导入模式，包括，url
到 from django.conf.urls 导入模式，包含，url

Answer 3

我也遇到了同样的问题，但我的做法与@Haimei 的做法相反

mysite/blog/urls.py from blog.views import archive 将其更改为

from mysite.blog.views import archive

它奏效了。

还要确保 .defaults 已从 from django.conf.urls.defaults 导入模式，包含，url

Answer 4

我的解决方案在这里：

mysite/blog/urls.py

from mysite.blog.views import archive 

到

from blog.views import archive

mysite/blog/view.py

from mysite.blog.models import BlogPost 

到

from blog.models import BlogPost

mysite/mysite/urls.py

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

到

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

这里我建议你在 settings.py 中将 DEBUG 设置为 true。当出现错误时，它可以告诉您应用程序停止的位置。在这种情况下，你只需要跳到这个地方。最好调试一下。
