Question

我是一个完整的django新手，我正在制作我的第一个应用程序而且我被困在管理员中。出于某种原因，我的模型/应用程序未显示在管理面板中。

在管理面板中，我收到以下错误

您无权修改任何内容。

我以超级用户身份登录。我证实了这一点。

    # Uncomment the next line to enable the admin:
    url(r'^admin/', include(admin.site.urls)),
)

Answer 1

在urls.py文件中取消注释这两行：

from django.contrib import admin
admin.autodiscover()

Answer 2

取消注释urls.py中的两行，这两行代表取消注释以启用admin ... autodiscover() is required。

# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
