How can I see the current urlpatterns that "reverse" is looking in?
I'm calling reverse in a view with an argument that I think should work, but doesn't. Any way I can check what's there and why my pattern isn't?

回答1:
./manage.py show_urlsManage should include this by feature by default.
edit After reading a comment I realized that this feature is provided by django-extensions (http://pypi.python.org/pypi/django-extensions/0.7.1)

Try this:
from django.core.urlresolvers import get_resolver get_resolver(None).reverse_dict.keys()回答3:
There is a recipe on activestate
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)回答4:
I am using the next command:
(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)Usage:
./manage.py showurlsSample output:

There's a plugin I use: https://github.com/django-extensions/django-extensions, it has a show_urls command that could help.
回答6:
Django 1.11, Python 2.7.6
cd to_your_django_project
python manage.py shell
Then paste following code.
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)Sample output:

I have extended Seti's command to show namespace, all url parts, auto-adjust column widths, sorted by (namespace,name): https://gist.github.com/andreif/263a3fa6e7c425297ffee09c25f66b20

OrderedDictin older versions.
Update: A new version with OrderedDict now lives in django-?s package: https://github.com/5monkeys/django-bananas/blob/master/bananas/management/commands/show_urls.py
回答9:
Simply type in a url you know does not exist and the server will return an error message with a list of url patterns.
For example, if you're running a site at http://localhost:8000/something
Type in
http://localhost:8000/something/blahNonsense, and your server will return the url search list and display it in the browser
