Question

我为models.py之一更改了through-model添加models。我UserProfileLanguage这是UserProfile，Language和Level之间的关系。每个UserProfile可以在不同Languages（技能）上有多个Levels。

现在我查看了Django-admin，看看我是否可以将Languages添加到Levels UserProfile，但我无法在那里看到它。

你知道问题出在哪里吗？

我已在languages模型中评论了属性UserProfile，因此您可以看到它。

这是我的models.py：

from __future__ import unicode_literals
# from django.contrib.auth.base_user import AbstractBaseUser
from django.contrib.auth.models import User
from django.db import models

    # I CANT SEE THIS ATTRIBUTE <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<
    languages = models.ManyToManyField(Language, through='UserProfileLanguage')

    rating = models.IntegerField(default=0)

    def __unicode__(self):

    def __str__(self):
        return '{} {}'.format(self.user.first_name, self.user.last_name)

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

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

class Job(models.Model):

    translator = models.ForeignKey(User, related_name='jobs',null=True)

    file = models.FileField(null=True,blank=True)
    language_tuple = models.ForeignKey(LanguageTuple,related_name='jobs')
    specialist = models.BooleanField(blank=True)

    # AUTOMATICKY GENEROVANE
    created = models.DateTimeField(auto_now_add=True)
    modified = models.DateTimeField(auto_now=True)

    is_active = models.BooleanField(default=False)

    is_done = models.BooleanField(default=False)

    @property
    def has_translator(self):
        return self.translator_id is not None


    def __str__(self):
        return '{}: {}'.format(self.customer,self.language_tuple)

在Django-admin中看不到模型属性
