Question

我正在使用react，redux和django-rest-framework设置Django应用程序。在Django中添加“客户”模型后，访问管理界面时出现ValueError。

即使通过删除以下行从管理界面中删除了所有模型之后，错误仍然会返回： admin.site.register(model)。

即使我刷新数据库，错误仍然不断返回。

我使用带有knox令牌的django用户模型登录django应用程序。

这是Pipenv中的本地Django安装。

我的预期结果是没有错误地访问Django Admin界面。我希望我已提供解决此问题所需的所有信息。

编辑： urls.py

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('', include('frontend.urls')),
    path('', include('leads.urls')),
    path('', include('accounts.urls')),
    path('', include('customer.urls')),
]

Answer 1

经过数小时的阅读和故障排除，我发现了错误。错误不在管理员，模型或api中。它在我的帐户应用程序的urls.py中。

这是我使用的代码：

path('api/auth/user/{id}', GetUserAPI.as_view()),

代替

path('api/auth/user/<id>', GetUserAPI.as_view()),

感谢您帮助解决给定的错误！

即使在刷新后，在/ admin /的Django ValueError
