【中文标题】Django 在导入 urls.py 时出现语法错误【英文标题】:Django giving syntax error when importing urls.py 【发布时间】:2013-10-28 12:35:59 【问题描述】:我的 testProject/urls.py 是这个
from django.conf.urls import patterns, include, url
from testapp import urls
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'testproject.views.home', name='home'),
# url(r'^testproject/', include('testproject.foo.urls')),
# Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
url(r'^admin/', include(admin.site.urls)),
url(r'^', include(urls)),
)
而我的 testApp/urls.py 就是这个
from django.conf.urls import patterns, include, url
from testapp.forms import UsersForm
from templates import login.html
urlpatterns = patterns('',
url(r'^$', 'django.contrib.auth.views.login', 'template_name': 'testproject/templates/login.html', 'authentication_form':UsersForm),
)
现在,当我运行服务器时
python manage.py runserver
它给了我一个
SyntaxError at /
说错了
invalid syntax (urls.py, line 3)
Request Method: GET
Request URL: http://127.0.0.1:8000/
Django Version: 1.5.2
Exception Type: SyntaxError
Exception Value:
invalid syntax (urls.py, line 3)
Exception Location: /home/ayman/Documents/djcode/testproject/testproject/urls.py in <module>, line 2
回溯是
Traceback:
File "/usr/local/lib/python2.7/dist-packages/django/core/handlers/base.py" in get_response
103. resolver_match = resolver.resolve(request.path_info)

319. for pattern in self.url_patterns:

347. patterns = getattr(self.urlconf_module, "urlpatterns", self.urlconf_module)

35. __import__(name)

2. from testapp import urls
Exception Type: SyntaxError at /
Exception Value: invalid syntax (urls.py, line 3)
知道为什么会引发语法错误吗?它很重,因为有些地方说错误在第 3 行,而其他地方说错误在第 2 行。请注意,几分钟前这还在工作,直到我决定更改并使用 Django 的通用登录视图。我将表单作为 authentication_form 传递时出错,我修复了该错误,但在修复该错误之后,引发了此语法错误。
之前关于将Form作为authentication_form传递的问题可以看这里作为参考
Django generic login view return 'str object not callable' error
把它包起来会有帮助。
【问题讨论】:
【参考方案1】:testapp.urls 有错误
from django.conf.urls import patterns, include, url
from testapp.forms import UsersForm
from templates import login.html
urlpatterns = patterns('',
url(r'^$', 'django.contrib.auth.views.login', 'template_name': 'testproject/templates/login.html', 'authentication_form':UsersForm),
)
from templates import login.html
不是你应该导入的东西,因为它不是 python 源代码。您只需删除此行即可。因为视图只需要一个字符串作为 template_name 的参数,不需要 Python 对象。
【讨论】:
【参考方案2】:请在 testProject/urls.py 中尝试以下操作:
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'^', include('testapp.urls')),
)
另一种方法:
from django.conf.urls import patterns, include, url
from testapp.urls import urlpatterns as testapp_urls
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
url(r'^admin/', include(admin.site.urls)),
url(r'^', include(testapp_urls)),
)
另请阅读文档的以下部分,关于 include
:https://docs.djangoproject.com/en/dev/topics/http/urls/#including-other-urlconfs
【讨论】:
奇怪,它现在给我一个 NameError 说“名称'testapp'未定义”在“url(r'^',include('testapp.urls'))”行.. 我试着让它 testproject.testapp.urls 然后它给出了一个名称错误,说“名称'testproject'没有定义”。我的项目称为 testproject,应用程序称为 testapp。我应该有一个 import 语句导入 testproject 吗? 您是否在 settings.py 的 INSTALLED_APPS 中包含了 testapp? 是的,在我的 settings.py 中,我的 INSTALLED_APPS 下确实有 testapp。 奇怪,它应该是这样工作的。您似乎忘记了“testapp.urls”中的引号。无论如何,我在答案中添加了另一种方法 - 请尝试。 hm 很奇怪,我尝试了新方法,现在它在“from testapp.urls import urlpatterns as testapp_urls”这一行给了我一个语法错误以上是关于Django 在导入 urls.py 时出现语法错误的主要内容,如果未能解决你的问题,请参考以下文章
使用 Django,有没有更好的方法在 urls.py 中动态导入视图?
