django resolve不解决

Question

我尝试了太多的东西，阅读了这些文档和其他相关的问题，以至于我对此变得疯狂和盲目，因为似乎很清楚错误在哪里，但我找不到它。

我的项目名称：“观察站”。

我的应用程序名：“tdcp”

我的dir结构是这样的

observatorio/
   settings.py
   urls.py
   manage.py
   ...
   tdcp/
       static/
       templates/
       __init__.py
       urls.py
       views.py
       models.py

一些我的settings.py：

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',
    'core',
    'tdcp',
    'south',
    'django.contrib.humanize',
)
ROOT_URLCONF = 'urls'
# ROOT_URLCONF = 'tdcp.urls'

我想把我的应用程序tdcp\urls.py包含在urls.py项目中，以便在将来创建更多的应用程序，并且从一开始就有一个更可伸缩的代码。所以：

我的项目urls.py：

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


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

urlpatterns = patterns('',
    url('', include('tdcp.urls', namespace='tdcp')),

    # 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)),
)

我的tdcp.urls.py：

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

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

urlpatterns = patterns('tdcp.views',
    url(r'^$', 'index', name='index'),
    url(r'^prueba$', 'prueba', name='prueba'),
    url(r'^all_urls_view', 'all_urls_view', name='all_urls_view'),
    url(r'^(?P<year>\d+)/(?P<metric>\w+)$', 'country_metric_view', name='country_metric_view'),
    url(r'^(?P<year>\d+)/(?P<province_code>\d+)/(?P<type>\w+)/(?P<metric>\w+)$', 'one_province_metric_view', name='one_province_metric_view'),
    url(r'^(?P<year>\d+)/(?P<ine_code>\w+)/(?P<metric>\w+)$', 'one_aapp_metric_view', name='one_aapp_metric_view'),
    url(r'^api/autocomplete_publicadministrations/$', 'autocomplete_publicadministrations', name='autocomplete_publicadministrations'),
    url(r'^api/autocomplete_indicators/', 'autocomplete_indicators', name='autocomplete_indicators'),
    url(r'^api/autocomplete_provinces/', 'autocomplete_provinces', name='autocomplete_provinces'),
    url(r'^navigation_form/', 'navigation_form', name='navigation_form'),

)

我认为这个设置是可以的，我可以访问我的任何页面，并且没有问题，除非我试图解析模板标签中的url。当我调用包含应用程序的urls.py时，错误必须出现在项目urls.py中，因为我发现，如果在我的settings.py中，它是这样设置的：

ROOT_URLCONF = 'tdcp.urls'

就像这样！！，它呈现页面并解析我模板中的任何url标记，如果我设置为：

# ROOT_URLCONF = 'urls'

因此，使用包含调用，它将停止解析urls。

我找到了这个ulrs解析器的shell测试，我试着找出了在反向()中使用的ulrs字典。当然，在这两种情况下都会发生这样的情况：

与ROOT_URLCONF = 'tdcp.urls‘

>>> from django.core import urlresolvers
>>> from tdcp import views
>>> print urlresolvers.get_resolver(None).reverse_dict
<MultiValueDict: {'index': [([(u'', [])], '$', {})], 'autocomplete_publicadministrations': [([(u'api/autocomplete_publicadministrations/', [])], 'api/autocomplete_publicadministrations/$', {})], 'autocomplete_provinces': [([(u'api/autocomplete_provinces/', [])], 'api/autocomplete_provinces/', {})], 'prueba': [([(u'prueba', [])], 'prueba$', {})], <function country_metric_view at 0x02004670>: [([(u'%(year)s/%(metric)s', [u'year', u'metric'])], '(?P<year>\\d+)/(?P<metric>\\w+)$', {})], 'one_province_metric_view': [([(u'%(year)s/%(province_code)s/%(type)s/%(metric)s', [u'year', u'province_code', u'type', u'metric'])], '(?P<year>\\d+)/(?P<province_code>\\d+)/(?P<type>\\w+)/(?P<metric>\\w+)$', {})], <function one_province_metric_view at 0x020046B0>: [([(u'%(year)s/%(province_code)s/%(type)s/%(metric)s', [u'year', u'province_code', u'type', u'metric'])], '(?P<year>\\d+)/(?P<province_code>\\d+)/(?P<type>\\w+)/(?P<metric>\\w+)$', {})], 'one_aapp_metric_view': [([(u'%(year)s/%(ine_code)s/%(metric)s', [u'year', u'ine_code', u'metric'])], '(?P<year>\\d+)/(?P<ine_code>\\w+)/(?P<metric>\\w+)$', {})], <function one_aapp_metric_view at 0x020046F0>: [([(u'%(year)s/%(ine_code)s/%(metric)s', [u'year', u'ine_code', u'metric'])], '(?P<year>\\d+)/(?P<ine_code>\\w+)/(?P<metric>\\w+)$', {})], 'navigation_form': [([(u'navigation_form/', [])], 'navigation_form/', {})], <function index at 0x02004630>: [([(u'', [])], '$', {})], <function all_urls_view at 0x01A917B0>: [([(u'all_urls_view', [])], 'all_urls_view', {})], <function autocomplete_provinces at 0x02004530>: [([(u'api/autocomplete_provinces/', [])], 'api/autocomplete_provinces/', {})], <function prueba at 0x020045F0>: [([(u'prueba', [])], 'prueba$', {})], 'autocomplete_indicators': [([(u'api/autocomplete_indicators/', [])], 'api/autocomplete_indicators/', {})], <function autocomplete_indicators at 0x02004570>: [([(u'api/autocomplete_indicators/', [])], 'api/autocomplete_indicators/', {})], <function navigation_form at 0x020045B0>: [([(u'navigation_form/', [])], 'navigation_form/', {})], 'country_metric_view': [([(u'%(year)s/%(metric)s', [u'year', u'metric'])], '(?P<year>\\d+)/(?P<metric>\\w+)$', {})], 'all_urls_view': [([(u'all_urls_view', [])], 'all_urls_view', {})], <function autocomplete_publicadministrations at 0x01FFC5F0>: [([(u'api/autocomplete_publicadministrations/', [])], 'api/autocomplete_publicadministrations/$', {})]}>
>>> print urlresolvers.get_resolver(None).reverse_dict.items()[0][0]
index

使用ROOT_URLCONF =‘url’

>>> from django.core import urlresolvers
>>> from tdcp import views
>>> print urlresolvers.get_resolver(None).reverse_dict <MultiValueDict: {}>
>>> print urlresolvers.get_resolver(None).reverse_dict.items()[0][0] Traceback (most recent call last):   File "<console>", line 1, in <module> IndexError: list index out of range

我做错什么了？？

再测试一次

I updated the project urls.py like this:
from django.conf.urls import patterns, include, url


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

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

    # project urls
    url(r'^hola', 'hola', name='hola'),

    # include app urls
    url(r'^/', include('tdcp.urls', namespace='tdcp')),
    )

所以现在，当我在shell中打印url解析字典时，它只会找到唯一挂起urls.py项目的静态url，没有一个包含的urls.py，无论是admin/还是我的应用程序tdcp/。

>>> from django.core import urlresolvers
>>> from tdcp import views
>>> print urlresolvers.get_resolver(None).reverse_dict
<MultiValueDict: {'hola': [([(u'hola', [])], 'hola', {}), ([(u'hola', [])], 'hola', {})]}>

Answer 1

我自己也是Django的新手，所以我不能百分之百地肯定这一点，但我认为部分问题可能在于您在项目urls.py中声明包含的正则表达式的方式。

而不是

url('', include('tdcp.urls', namespace='tdcp'))

试一试

url(r'^/', include('tdcp.urls', namespace='tdcp'))。

以下是Django文档中的相关片段：

请注意，本例中的正则表达式没有$(字符串结束匹配字符)，但包含一个尾随斜杠。每当Django遇到include()时，它会将URL的任何部分剪掉，并将剩余的字符串发送到包含的URLconf进行进一步处理。

由于您在空regex中传递，所以整个URL匹配，因此没有什么可以传递给包含的URLConf。我不知道它将如何与反向解析器，但它可能是打破了这一点，也。(我快速浏览了Django代码，看看它是否是特殊情况下的空字符串，但没有看到--可能我错过了它。)
