Wie kann ich die aktuellen URL-Muster sehen, in denen "reverse" angezeigt wird?

Ich rufe Reverse in einer Ansicht mit einem Argument auf, von dem ich denke, dass es funktionieren sollte, aber nicht. Wie kann ich überprüfen, was da ist und warum mein Muster nicht?

Wenn Sie eine Liste aller URLs in Ihrem Projekt wünschen, müssen Sie zuerst Django-Erweiterungen installieren und diese wie folgt zu Ihren Einstellungen hinzufügen:

INSTALLED_APPS = (
...
'django_extensions',
...
)

Führen Sie dann diesen Befehl in Ihrem Terminal aus

./manage.py show_urls

Weitere Informationen finden Sie in der Dokumentation.

Versuche dies:

from django.urls import get_resolver
get_resolver().reverse_dict.keys()

Oder wenn Sie noch auf Django 1 sind. *:

from django.core.urlresolvers import get_resolver
get_resolver(None).reverse_dict.keys()

Django> = 2.0 Lösung

Ich habe die anderen Antworten in diesem Beitrag getestet und sie funktionierten entweder nicht mit Django 2.X, unvollständig oder zu komplex. Deshalb hier meine Meinung dazu:

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))

Dieser Code druckt alle URLs, im Gegensatz zu einigen anderen Lösungen wird der vollständige Pfad und nicht nur der letzte Knoten gedruckt. z.B:

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 Shell

Fügen Sie dann den folgenden Code ein.

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)

Beispielausgabe:

^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/^(.+)/$
...

Es gibt ein Rezept für 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)

Ich benutze den nächsten Befehl:

(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)

Verwendung:

./manage.py showurls

Ich verwende ein Plugin: https://github.com/django-extensions/django-extensions . Es enthält einen Befehl show_urls, der helfen könnte.

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

In der Python-Shell "manage.py"

import urls
get_resolved_urls(urls.urlpatterns)

In Django 3.0 ist es so einfach wie:

from django.urls import get_resolver
print(get_resolver().url_patterns)

Drucke: [<URLPattern '' [name='home']>, <URLPattern '/testing' [name='another_url']>]

Ich habe den Befehl von Seti erweitert , um den Namespace, alle URL-Teile und die Spaltenbreiten automatisch anzupassen, sortiert nach (Namespace, Name): https://gist.github.com/andreif/263a3fa6e7c425297ffee09c25f66b20

import sys
from django.core.management import BaseCommand
from django.conf.urls import RegexURLPattern, RegexURLResolver
from django.core import urlresolvers


def collect_urls(urls=None, namespace=None, prefix=None):
    if urls is None:
        urls = urlresolvers.get_resolver()
    _collected = []
    prefix = prefix or []
    for x in urls.url_patterns:
        if isinstance(x, RegexURLResolver):
            _collected += collect_urls(x, namespace=x.namespace or namespace,
                                       prefix=prefix + [x.regex.pattern])
        elif isinstance(x, RegexURLPattern):
            _collected.append({'namespace': namespace or '',
                               'name': x.name or '',
                               'pattern': prefix + [x.regex.pattern],
                               'lookup_str': x.lookup_str,
                               'default_args': dict(x.default_args)})
        else:
            raise NotImplementedError(repr(x))
    return _collected


def show_urls():
    all_urls = collect_urls()
    all_urls.sort(key=lambda x: (x['namespace'], x['name']))

    max_lengths = {}
    for u in all_urls:
        for k in ['pattern', 'default_args']:
            u[k] = str(u[k])
        for k, v in list(u.items())[:-1]:
            # Skip app_list due to length (contains all app names)
            if (u['namespace'], u['name'], k) == \
                    ('admin', 'app_list', 'pattern'):
                continue
            max_lengths[k] = max(len(v), max_lengths.get(k, 0))

    for u in all_urls:
        sys.stdout.write(' | '.join(
            ('{:%d}' % max_lengths.get(k, len(v))).format(v)
            for k, v in u.items()) + '\n')


class Command(BaseCommand):
    def handle(self, *args, **kwargs):
        show_urls()

Hinweis: Die Spaltenreihenfolge wird in Python 3.6 beibehalten und muss OrderedDictin älteren Versionen verwendet werden.

Update: Eine neue Version mit OrderedDict befindet sich jetzt im Paket von django: https://github.com/5monkeys/django-bananas/blob/master/bananas/management/commands/show_urls.py

Geben Sie einfach eine URL ein, von der Sie wissen, dass sie nicht vorhanden ist, und der Server gibt eine Fehlermeldung mit einer Liste von URL-Mustern zurück.

Zum Beispiel, wenn Sie eine Site unter http: // localhost: 8000 / Something ausführen

Eintippen

http: // localhost: 8000 / Something / blahNonsense , und Ihr Server gibt die URL-Suchliste zurück und zeigt sie im Browser an

Minimalistische Lösung für Django 2.0

Wenn Sie beispielsweise nach einer URL suchen, die in der ersten App von installierten_Apps enthalten ist, können Sie folgendermaßen darauf zugreifen:

from django.urls import get_resolver
from pprint import pprint

pprint(
    get_resolver().url_patterns[0].url_patterns
)

Django 1.8, Python 2.7+ Führen Sie diese Befehle einfach in Ihrer Shell aus. Python verwalten.py Shell und führen Sie den folgenden Code.

from django.conf.urls import RegexURLPattern, RegexURLResolver
from django.core import urlresolvers
urls = urlresolvers.get_resolver(None)

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)

Sie können einen dynamischen Import erstellen, um alle URL-Muster aus jeder Anwendung in Ihrem Projekt mit einer einfachen Methode wie der folgenden zu erfassen:

def get_url_patterns():
    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()

Ich habe kürzlich so etwas verwendet, um ein Vorlagen-Tag zu erstellen, auf dem aktive Navigationslinks angezeigt werden.

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

Hier your_main_appist der App-Name, unter dem sich Ihre Datei settings.py befindet
