¿Cómo puedo ver los patrones de url actuales en los que se está viendo "reverse"?

Estoy llamando al revés en una vista con un argumento que creo que debería funcionar, pero no funciona. ¿De alguna manera puedo verificar qué hay allí y por qué mi patrón no lo está?

Si desea una lista de todas las URL en su proyecto, primero necesita instalar django-extensions , agréguelo a su configuración de esta manera:

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

Y luego, ejecuta este comando en tu terminal

./manage.py show_urls

Para más información puede consultar la documentación.

Prueba esto:

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

O si todavía estás en Django 1. *:

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

Django> = solución 2.0

Probé las otras respuestas en esta publicación y no funcionaban con Django 2.X, incompletas o demasiado complejas. Por lo tanto, aquí está mi opinión sobre esto:

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))

Este código imprime todas las URL, a diferencia de otras soluciones, imprimirá la ruta completa y no solo el último nodo. p.ej:

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

Luego pegue el siguiente código.

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)

Hay una receta en estado activo

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)

Estoy usando el siguiente comando:

(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)

Uso:

./manage.py showurls

Hay un complemento que uso: https://github.com/django-extensions/django-extensions , tiene un comando show_urls que podría ayudar.

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

En python manage.py shell

import urls
get_resolved_urls(urls.urlpatterns)

En Django 3.0, es tan fácil como:

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

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

He extendido el comando de Seti para mostrar el espacio de nombres, todas las partes de url, ajustar automáticamente los anchos de columna, ordenados por (espacio de nombres, nombre): 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()

Nota: el orden de las columnas se mantiene en Python 3.6 y sería necesario usarlo OrderedDicten versiones anteriores.

Actualización: una nueva versión con OrderedDict ahora vive en el paquete django-🍌s: https://github.com/5monkeys/django-bananas/blob/master/bananas/management/commands/show_urls.py

Simplemente escriba una url que sabe que no existe y el servidor devolverá un mensaje de error con una lista de patrones de url.

Por ejemplo, si está ejecutando un sitio en http: // localhost: 8000 / something

Escribir

http: // localhost: 8000 / something / blahNonsense , y su servidor devolverá la lista de búsqueda de URL y la mostrará en el navegador

Solución minimalista para django 2.0

Por ejemplo, si está buscando una URL que esté en la primera aplicación de instalted_apps, puede acceder de esta manera:

from django.urls import get_resolver
from pprint import pprint

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

Django 1.8, Python 2.7+ Simplemente ejecute estos comandos en su Shell. Python manage.py shell y ejecuta el siguiente código.

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)

Puede crear una importación dinámica para reunir todos los patrones de URL de cada aplicación en su proyecto con un método simple como este:

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()

Recientemente utilicé algo como esto para crear una etiqueta de plantilla para mostrar enlaces de navegación activos.

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

Aquí your_main_appestá el nombre de la aplicación donde se ubica su archivo settings.py
