Django：django.urls.exceptions.NoReverseMatch：找不到“view_name”的反向。 “view_name”不是有效的视图函数或模式名称

Question

我正在尝试对我的视图进行测试，但出现此错误：

Django: django.urls.exceptions.NoReverseMatch: Reverse for 'create' not found. 'create' is not a valid view function or pattern name.

这是我的测试：

from django.urls import reverse
from django.test import TestCase
from rest_framework import status
from rest_framework.test import APIClient
from users.models import User

class UsersTests(TestCase):
    def setUp(self):
        self.client = APIClient()
        self.user = User.objects.create(chat_id=123456789, language='en')

    def test_create_valid_user(self):
        response = self.client.post(
            reverse('users:create'),
            data = {
            'chat_id': 1234,
            'language': 'en'
            },
            format='json'
        )
        self.assertEqual(response.status_code, status.HTTP_201_CREATED)
        self.assertEqual(User.objects.count(), 2)

用户/urls.py:

from django.urls import path
from . import views

app_name = 'users'

urlpatterns = [
    path('get-all/', views.get_all),
    path('create/', views.create),
    path('get-by-chat-id/<int:chat_id>/', views.get_by_chat_id),
    path('update/<int:chat_id>/', views.update)
]

app/urls.py（主 urls.py）：

from django.urls import path, include

urlpatterns = [
    path('users/', include('users.urls', namespace='users')),
]

$ python manage.py show_urls

的输出：

/users/create/  users.views.create      
/users/get-all/ users.views.get_all     
/users/get-by-chat-id/<int:chat_id>/    users.views.get_by_chat_id      
/users/update/<int:chat_id>/    users.views.update 

我相信

reverse('users:create')

引发了错误，我尝试了很多东西但无法修复它。
请告诉我如何解决它。

你应该给路径命名：

app_name = 'users'

urlpatterns = [
    # ...
    path('create/', views.create, name='create'),
    # ...
]
