python - 用于创建 AbstractUser 扩展模型的 Django 管理表单

Question

我有一个扩展/继承 AbstractUser 的客户用户模型。我还希望管理员中的用户创建表单匹配，但出于某种原因我只能让它显示用户名和密码字段。没有其他的。

我发现特别有趣的是，我对 admin.py 中的这 3 个字段所做的更改反射(reflect)在创建表单中，但其他字段从未显示。因此，例如，我可以更改密码 1 的帮助文本或标签，并在表单中呈现它，但其他字段不会。

此外，如果我设置扩展 UserAdmin 并注册它(如下面的代码所示)，我将获得通用用户的 3 字段创建 View ，但如果我扩展 ModelAdmin，我将获得所有字段，但无法使用密码更新表单。它 404s。

还值得注意的是，指向对象列表的链接是“User”，而不是我的模型所调用的“CommonUser”，但这可能是某处的类元。

Extending new user form, in the admin Django Using Django auth UserAdmin for a custom user model https://docs.djangoproject.com/en/1.6/topics/auth/customizing/#a-full-example

Answer 1

django.contrib.auth.admin 中的 UserAdmin 还设置了“add_fieldsets”属性，该属性设置要在添加用户 View 中显示的字段。由于 UserAdmin 设置了该字段，您需要覆盖它以设置您自己的字段。

这是一个例子:

class CustomUserAdmin(UserAdmin):
# ...code here...

    fieldsets = (
        (None, {'fields': ('email',)}),
        (_('Personal info'), {'fields': ('first_name', 'last_name')}),
        (_('Permissions'), {'fields': ('is_active', 'is_staff', 'is_superuser',
                                       'groups', 'user_permissions')}),
        (_('Important dates'), {'fields': ('last_login', 'date_joined')}),
    )
    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('email', 'first_name', 'last_name', 'password1',
                       'password2')}
         ),
    )

希望这对您有所帮助!
