Question

我对Django-Admin有点问题。所以我有一个模型UserProfile，它扩展了一个regulear User。还有其他模型：Language，Level和UserProfileLanguage这是一个直通模型。

class UserProfileLanguage(models.Model):
    userprofile = models.ForeignKey(UserProfile)
    language = models.ForeignKey(Language)
    level = models.ForeignKey(Level)

    class Meta:
        unique_together = (('userprofile', 'language'),)

问题是我无法在languages的{{1}}标签中看到属性User：

Django-Admin

所以我决定将其明确地放在class UserProfile(... ... languages = models.ManyToManyField(Language, through='UserProfileLanguage')标签中，以便User：

admin.py

CMD说：

from django.contrib import admin
from models import *
from django.contrib.auth.admin import UserAdmin as BaseUserAdmin
admin.site.register(AdminContact)

class UserProfileInline(admin.StackedInline):
    model = UserProfile
    can_delete = False
    verbose_name_plural = 'User_Profile'

# this does not work
class UserProfileLanguageLevelInline(admin.StackedInline):
    model = UserProfileLanguage

class UserAdmin(BaseUserAdmin):
    inlines = (UserProfileInline,UserProfileLanguageLevelInline, )


admin.site.unregister(User)
admin.site.register(User,UserAdmin)
admin.site.register(LanguageTuple)
admin.site.register(Language)
admin.site.register(Job)
admin.site.register(UserProfileLanguage)

问题在于ERRORS: <class 'SolutionsForLanguagesApp.admin.UserProfileLanguageLevelInline'>: (admin. E202) 'SolutionsForLanguagesApp.UserProfileLanguage' has no ForeignKey to 'auth. User'.与UserProfileLanguage和UserProfile与UserProfile相关联。你知道该怎么办吗？

'Model'没有'auth的ForeignKey。用户'
