如何查看“反向”正在查看的当前 urlpatterns？
我在一个视图中调用 reverse ，我认为它应该有效，但没有。任何方式我都可以检查那里有什么以及为什么我的模式不是？

如果你想要项目中所有 url 的列表，首先你需要安装 django-extensions
您可以使用命令简单地安装。
pip install django-extensions
有关包 goto django-extensions 的更多信息
之后，像这样django_extensions在INSTALLED_APPS您的settings.py文件中添加：
INSTALLED_APPS = (
...
'django_extensions',
...
)
urls.py 示例：
from django.urls import path, include
from . import views
from . import health_views
urlpatterns = [
path('get_url_info', views.get_url_func),
path('health', health_views.service_health_check),
path('service-session/status', views.service_session_status)
]
然后，在终端中运行任何命令
python manage.py show_urls
或者
./manage.py show_urls
基于配置 urls.py 的示例输出示例：
/get_url_info django_app.views.get_url_func
/health django_app.health_views.service_health_check
/service-session/status django_app.views.service_session_status
有关更多信息，您可以查看文档。

尝试这个：
from django.urls import get_resolver
get_resolver().reverse_dict.keys()
或者，如果您仍在使用 Django 1.*：
from django.core.urlresolvers import get_resolver
get_resolver(None).reverse_dict.keys()

Django >= 2.0 解决方案
我测试了这篇文章中的其他答案，它们要么不能使用 Django 2.X，要么不完整，要么太复杂。因此，这是我对此的看法：
from django.conf import settings
from django.urls import URLPattern, URLResolver
urlconf = __import__(settings.ROOT_URLCONF, {}, {}, [''])
def list_urls(lis, acc=None):
if acc is None:
acc = []
if not lis:
return
l = lis[0]
if isinstance(l, URLPattern):
yield acc + [str(l.pattern)]
elif isinstance(l, URLResolver):
yield from list_urls(l.url_patterns, acc + [str(l.pattern)])
yield from list_urls(lis[1:], acc)
for p in list_urls(urlconf.urlpatterns):
print(''.join(p))
此代码打印所有 URL，与其他一些解决方案不同，它将打印完整路径，而不仅仅是最后一个节点。例如：
admin/
admin/login/
admin/logout/
admin/password_change/
admin/password_change/done/
admin/jsi18n/
admin/r/<int:content_type_id>/<path:object_id>/
admin/auth/group/
admin/auth/group/add/
admin/auth/group/autocomplete/
admin/auth/group/<path:object_id>/history/
admin/auth/group/<path:object_id>/delete/
admin/auth/group/<path:object_id>/change/
admin/auth/group/<path:object_id>/
admin/auth/user/<id>/password/
admin/auth/user/
... etc, etc

Django 1.11，Python 2.7.6
cd to_your_django_project
python manage.py 外壳
然后粘贴以下代码。
from django.conf.urls import RegexURLPattern, RegexURLResolver
from django.core import urlresolvers
urls = urlresolvers.get_resolver()
def if_none(value):
if value:
return value
return ''
def print_urls(urls, parent_pattern=None):
for url in urls.url_patterns:
if isinstance(url, RegexURLResolver):
print_urls(url, if_none(parent_pattern) + url.regex.pattern)
elif isinstance(url, RegexURLPattern):
print(if_none(parent_pattern) + url.regex.pattern)
print_urls(urls)

在 Django 3.0 中，这很简单：
from django.urls import get_resolver
print(get_resolver().url_patterns)
印刷：
[<URLPattern '' [name='home']>, <URLPattern '/testing' [name='another_url']>]

from django.conf.urls import RegexURLPattern, RegexURLResolver
from django.core import urlresolvers
class Command(BaseCommand):

all_urls = list()

return i.name
def show_urls(urls):
for url in urls.url_patterns:
if isinstance(url, RegexURLResolver):
show_urls(url)
elif isinstance(url, RegexURLPattern):
all_urls.append(url)
show_urls(urls)
all_urls.sort(key=func_for_sorting, reverse=False)
print('-' * 100)
for url in all_urls:
print('| {0.regex.pattern:20} | {0.name:20} | {0.lookup_str:20} | {0.default_args} |'.format(url))
print('-' * 100)

这是一个快速而肮脏的技巧，无需修改任何设置即可获得所需的信息。
$ pip install django-extensions
$ python manage.py shell -c 'from django.core.management import call_command; from django_extensions.management.commands.show_urls import Command; call_command(Command())'
这是对@robert 的回答的小猪支持。虽然正确，但我不想django-extensions依赖它，即使它只是一秒钟。

只需输入您知道不存在的 url，服务器将返回带有 url 模式列表的错误消息。
例如，如果您在http://localhost:8000/something上运行一个站点
输入
http://localhost:8000/something/blahNonsense，你的服务器会返回url搜索列表并显示在浏览器中

您可以使用如下简单的方法创建动态导入以从项目中的每个应用程序中收集所有 URL 模式：
def get_url_patterns():
import importlib
from django.apps import apps
list_of_all_url_patterns = list()
for name, app in apps.app_configs.items():
# you have a directory structure where you should be able to build the correct path
# my example shows that apps.[app_name].urls is where to look
mod_to_import = f'apps.{name}.urls'
try:
urls = getattr(importlib.import_module(mod_to_import), "urlpatterns")
list_of_all_url_patterns.extend(urls)
except ImportError as ex:
# is an app without urls
pass
return list_of_all_url_patterns
list_of_all_url_patterns = get_url_patterns()
我最近使用这样的东西来创建一个模板标签来显示活动的导航链接。
