Bagaimana saya bisa melihat pola url saat ini yang melihat "terbalik"?

Saya menelepon terbalik dalam pandangan dengan argumen yang menurut saya harus berhasil, tetapi tidak. Dengan cara apa pun saya dapat memeriksa apa yang ada di sana dan mengapa pola saya tidak?

Jika Anda menginginkan daftar semua url dalam proyek Anda, pertama-tama Anda perlu menginstal django-extensions , tambahkan ke pengaturan Anda seperti ini:

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

Dan kemudian, jalankan perintah ini di terminal Anda

./manage.py show_urls

Untuk informasi lebih lanjut, Anda dapat memeriksa dokumentasi.

Coba ini:

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

Atau jika Anda masih di Django 1. *:

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

Django> = 2.0 solusi

Saya menguji jawaban lain dalam posting ini dan mereka tidak bekerja dengan Django 2.X, tidak lengkap atau terlalu rumit. Karena itu, inilah pendapat saya tentang ini:

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))

Kode ini mencetak semua URL, tidak seperti beberapa solusi lain, kode ini akan mencetak jalur lengkap dan tidak hanya node terakhir. misalnya:

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_proyek_django_anda

python manage.py shell

Kemudian tempel kode berikut.

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)

Output sampel:

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

Ada resep di 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)

Saya menggunakan perintah selanjutnya:

(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)

Pemakaian:

./manage.py showurls

Ada plugin yang saya gunakan: https://github.com/django-extensions/django-extensions , ia memiliki perintah show_urls yang dapat membantu.

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

Dalam python manage.py shell

import urls
get_resolved_urls(urls.urlpatterns)

Di Django 3.0, semudah:

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

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

Saya telah memperpanjang perintah Seti untuk menampilkan namespace, semua bagian url, lebar kolom penyesuaian otomatis, diurutkan berdasarkan (namespace, nama): 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()

Catatan: urutan kolom disimpan di Python 3.6 dan harus digunakan OrderedDictdi versi yang lebih lama.

Pembaruan: Versi baru dengan OrderedDict sekarang ada di paket django-🍌s: https://github.com/5monkeys/django-bananas/blob/master/bananas/management/commands/show_urls.py

Cukup ketik url yang Anda tahu tidak ada dan server akan mengembalikan pesan kesalahan dengan daftar pola url.

Misalnya, jika Anda menjalankan situs di http: // localhost: 8000 / sesuatu

Ketik

http: // localhost: 8000 / sesuatu / blahNonsense , dan server Anda akan mengembalikan daftar pencarian url dan menampilkannya di browser

Solusi minimalis untuk django 2.0

Misalnya, jika Anda mencari url yang ada di aplikasi pertama dari instal_apps, Anda dapat mengaksesnya seperti itu:

from django.urls import get_resolver
from pprint import pprint

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

Django 1.8, Python 2.7+ Jalankan saja perintah ini di Shell Anda. Python manage.py shell dan jalankan kode berikut.

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)

Anda dapat membuat impor dinamis untuk mengumpulkan semua Pola URL dari setiap aplikasi dalam proyek Anda dengan metode sederhana seperti:

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()

Saya baru-baru ini menggunakan sesuatu seperti ini untuk membuat tag template untuk menampilkan link navigasi yang aktif.

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

Berikut your_main_appadalah nama aplikasi tempat file settings.py Anda ditempatkan
