我怎么能看到当前的urlpatterns“反向”正在寻找?
我在一个视图中调用了逆向，我认为这个论证应该成立，但实际上并不成立。有什么办法能让我知道为什么我的图案没有?
当前回答
我正在使用下面的命令:
（Python3 + Django 1.10）
from django.core.management import BaseCommand
from django.conf.urls import RegexURLPattern, RegexURLResolver
from django.core import urlresolvers
class Command(BaseCommand):
def add_arguments(self, parser):
pass
def handle(self, *args, **kwargs):
urls = urlresolvers.get_resolver()
all_urls = list()
def func_for_sorting(i):
if i.name is None:
i.name = ''
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)
用法:
./manage.py showurls
样例输出:

有一个activestate的配方
import urls
def show_urls(urllist, depth=0):
for entry in urllist:
print(" " * depth, entry.regex.pattern)
if hasattr(entry, 'url_patterns'):
show_urls(entry.url_patterns, depth + 1)
show_urls(urls.url_patterns)
如果你想要一个项目中所有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，在settings.py文件中的INSTALLED_APPS中添加django_extensions，如下所示:
INSTALLED_APPS = (
...
'django_extensions',
...
)
urls . py的例子:
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，在终端上运行任意命令
python manage.py show_urls
or
./manage.py show_urls
基于config urls.py的输出示例:
/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。
你可以创建一个动态导入来收集项目中每个应用程序的所有URL模式，简单的方法如下:
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()
我最近使用类似的方法创建了一个模板标记来显示活动导航链接。
如果你正在使用DRF，你可以通过从router.get_urls()(在你的Django应用的urls.py文件中)打印特定路由器的urlpatterns来打印所有的URL模式。
打开你的apps urls.py，并在文件底部添加打印语句，这样整个文件看起来就像这样:
import pprint
from django.urls import include, path
from rest_framework import routers
from . import views
router = routers.DefaultRouter()
router.register(r"users", views.UserViewSet, basename="User")
router.register(r"auth", views.AuthenticationView, basename="Auth")
router.register(r"dummy", views.DummyViewSet, basename="Dummy")
router.register("surveys", views.SurveyViewSet, basename="survey")
urlpatterns = [
path("", include(router.urls)),
]
pprint.pprint(router.get_urls())
然后，这些图案会像这样打印出来:
[<URLPattern '^users/$' [name='User-list']>,
<URLPattern '^users\.(?P<format>[a-z0-9]+)/?$' [name='User-list']>,
<URLPattern '^users/admins/$' [name='User-admins']>,
<URLPattern '^users/admins\.(?P<format>[a-z0-9]+)/?$' [name='User-admins']>,
<URLPattern '^users/current/$' [name='User-current']>,
<URLPattern '^users/current\.(?P<format>[a-z0-9]+)/?$' [name='User-current']>,
<URLPattern '^users/(?P<pk>[^/.]+)/$' [name='User-detail']>,
<URLPattern '^users/(?P<pk>[^/.]+)\.(?P<format>[a-z0-9]+)/?$' [name='User-detail']>,
<URLPattern '^auth/login/$' [name='Auth-login']>,
...
]
def get_resolved_urls(url_patterns):
url_patterns_resolved = []
for entry in url_patterns:
if hasattr(entry, 'url_patterns'):
url_patterns_resolved += get_resolved_urls(
entry.url_patterns)
else:
url_patterns_resolved.append(entry)
return url_patterns_resolved
在python中manage.py shell
import urls
get_resolved_urls(urls.urlpatterns)
