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
试试这个:
from django.urls import get_resolver
get_resolver().reverse_dict.keys()
或者如果你还在Django 1上。*:
from django.core.urlresolvers import get_resolver
get_resolver(None).reverse_dict.keys()

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。
只要输入一个你知道不存在的url，服务器就会返回一个错误消息，其中包含一个url模式列表。
例如，如果你在http://localhost:8000/something上运行一个网站
输入
http://localhost:8000/something/blahNonsense，您的服务器将返回url搜索列表并在浏览器中显示它
from django.urls.resolvers import RegexPattern,RoutePattern
from your_main_app import urls
def get_urls():
url_list = []
for url in urls.urlpatterns:
url_list.append(url.pattern._regex) if isinstance(url.pattern, RegexPattern) else url_list.append(url.pattern._route)
return url_list
这里your_main_app是放置settings.py文件的应用程序名称
Django 1.11, Python 2.7.6
cd to_your_django_project Python manage.py shell
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)
样例输出:
^django-admin/^$
^django-admin/^login/$
^django-admin/^logout/$
^django-admin/^password_change/$
^django-admin/^password_change/done/$
^django-admin/^jsi18n/$
^django-admin/^r/(?P<content_type_id>\d+)/(?P<object_id>.+)/$
^django-admin/^wagtailimages/image/^$
^django-admin/^wagtailimages/image/^add/$
^django-admin/^wagtailimages/image/^(.+)/history/$
^django-admin/^wagtailimages/image/^(.+)/delete/$
^django-admin/^wagtailimages/image/^(.+)/change/$
^django-admin/^wagtailimages/image/^(.+)/$
...
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
