我创建了一个自定义用户，如何将它们添加到组中？

Question

我在我的项目中途创建了一个自定义用户，称为 OUser，在一个名为 accounts 的应用程序中。我在默认 AuthUserGroups 中定义了一些现有组。如何将 OUser 添加到组？当我尝试时，我得到一个错误，Invalid column name 'ouser_id'。我需要做什么才能允许将 OUser 添加到我的预定义组中？我是否必须创建自定义组模型来放置我的 OUser？无论如何我可以告诉 Auth_User_groups 它应该寻找 OUsers 吗？

accounts.admin

class OUserAdmin(BaseUserAdmin):
    # The forms to add and change user instances
    form = UserAdminChangeForm
    add_form = UserAdminCreationForm

    # The fields to be used in displaying the User model.
    # These override the definitions on the base UserAdmin
    # that reference specific fields on auth.User.
    fieldsets = (
        ('Personal info', {'fields': ('first_name', 'last_name', 'email',)}),
        ('Permissions', {'fields': ('is_superuser', 'is_active', 'is_staff',)}),
    )
    # add_fieldsets is not a standard ModelAdmin attribute. UserAdmin
    # overrides get_fieldsets to use this attribute when creating a user.
    add_fieldsets = (
        (None, {
            'classes': ('wide',),
            'fields': ('username',)}
        ),
    )
    search_fields = ('username',)
    ordering = ('username',)
    filter_horizontal = ()
    list_filter = ('is_superuser',)



admin.site.register(OUser, OUserAdmin)
'''



There are also other dependencies on things, such as Auth_Group_permission, but I assume that it will be a similar fix to switching Auth_Group to using OUser. 

How would I make groups contain references to Ouser. I have tried just swapping the Foreign key of the user_id in AuthUserGroups to contain a reference to OUser, but that didn't work. Maybe I missed something?

Thanks for the help!

Answer 1

AuthUserGroups 是一个表，其中包含User 和Group 之间的ManyToMany 关系。它对这些模型有外键约束。您不能拥有与 OUsers 和 User 都具有外键关系的字段

您需要创建一个不同的ManyToMany 关系表单OUsers 到Group，它通过一个单独的表。

这是一个将其添加到 OUser 模型的示例

from django.contrib.auth.models import Group

class OUsers(models.Model):
    ...
    groups = models.ManyToManyField(Group)
