运行时属性错误 Django Rest API

Question

I have created a simple project called djangowallet and inside that project, I have created an app called wallet with a model wallet and just one field called raddress .

I have created the serializer, views and URLs and when I runserver it gives the following error.

PS C:\Users\Ahmed\djangowallet> python manage.py runserver
Watching for file changes with StatReloader
Performing system checks...

Exception in thread django-main-thread:

    if e.tag == XINCLUDE_INCLUDE:

This is my URL file in the project directory.

from xml.etree.ElementInclude import include
from django.contrib import admin
from django.urls import path

urlpatterns = [
    path('admin/', admin.site.urls),
    path('wallet/', include('wallet.urls'))
]

This is the URL file in the wallet app

from django.urls import include, path
from rest_framework import routers
from . import views

router = routers.DefaultRouter()
router.register(r'wallet', views.WalletViewSet)

# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
    path('', include(router.urls)),
]

Seems you are looking to useinclude ..[Django-doc] so just change:

from xml.etree.ElementInclude import include

to:

from django.urls import include
