Django-/ blog中的importError。 （没有名为url的模块）

Question

While studying Django tutorial (the book is Python Web Development with Django), I've been getting an import error.

I've looked for a solution on here and with Google, but I couldn't find one that worked.

My error is ImportError at /blog. No module named urls. ImportError at /blog. No module named urls.

I'm using django 1.5.1 .

My files are structure -

 - 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

    'django.template.loaders.filesystem.Loader',
    'django.template.loaders.app_directories.Loader',

Answer 1

I think you have to change this line:

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

to this:

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

Hope it helps!

Answer 2

My solution is here:

mysite/blog/urls.py

from mysite.blog.views import archive 

to

from blog.views import archive

mysite/blog/view.py

from mysite.blog.models import BlogPost 

to

from blog.models import BlogPost

mysite/mysite/urls.py

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

to

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

Here I suggest you to set DEBUG true in settings.py . when there is mistake, it can tell you the place where the application stop. In this case, you just need to jump to this place. It would be better to debug.

Answer 3

change this file mysite/blog/urls.py from django.conf.urls.defaults import patterns, include, url
to from django.conf.urls import patterns, include, url

Answer 4

I have been having the same problem but I did just the opposite of what @Haimei did

mysite/blog/urls.py from blog.views import archive changed it to

from mysite.blog.views import archive

and it worked.

also make sure that .defaults is removed from from django.conf.urls.defaults import patterns, include, url
