If you see valid patterns in the file then the issue is probably caused by a circular import.
Исходный код файла AI_Chatbot_Server.urls ':
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
# chatbot app url list
path('ai_chat_bot/', include("apps.chatbot.urls")),
path('ai_chat_bot/users/', include("apps.users.urls")),
path('ai_chat_bot/weather/', include("apps.weather.urls")),
]
Update-1:
URL модуля пользователя:
from django.urls import path
from .controller import login_controller
urlpatterns = [
path('login', login_controller.LoginController.login, name='login'),
]
URL модуля Chatbot:
from django.urls import path
from .controller import chatbot_main_controller
urlpatterns = [
path('get_question/', chatbot_main_controller.ChatBotMainController.get_question, name="get_question"),
]
Погодный модуль usrls:
from django.urls import path
from ..weather.controller import weather_info_controller
urlpatterns = [
path('get_weather_info/', weather_info_controller.WeatherInfoController.get_weather_info, name="get_weather_info"),
]
Update-2:
У меня есть общая папка со структурой пользователей, чатбот и модуль погоды:
