如何在 django 中建立投票问题数据库？

Question

我想跟踪用户投票的问题和答案（上下），所以我就是这样做的，它不起作用

这是我的问题课

class Question(models.Model):
    question = models.CharField(max_length = 200)
    questionbody = models.TextField()
    questioncontent = models.TextField()
    author = models.ForeignKey(User)
    tags = models.ManyToManyField(Tag)
    timestamp = models.DateTimeField('question post date')
    upvote = models.IntegerField(default = 0)
    downvote = models.IntegerField(default = 0)
    view = models.IntegerField(default = 0)

这是我的用户档案类（扩展用户）

class UserProfile(models.Model):
    user = models.OneToOneField(User)
    tags = models.ManyToManyField(Tag) 
    # favorite_question = models.ManyToManyField(Question)
    # upvote_question = models.ManyToManyField(Question)
    # downvote_question = models.ManyToManyField(Question)
    # upvote_answer = models.ManyToManyField(Answer)
    # downvote_answer = models.ManyToManyField(Answer)
    integration = models.IntegerField(default = 0)
    level = models.CharField(max_length = 100)

如果取消注释该行 运行 synvdb 命令会报错

 access for m2m field 'favorite-question' clashes with related m2m field 'question-userprofile_set',add a related_name argument to thr definition for 'favorite-question'

其余 4 行显示相同的错误。我真的是 django 新手，请帮助

关于错误，如果要跨模型使用相同类型的关系，则必须定义相关名称：

例如：

favorite_question = models.ManyToManyField(Question, related_name='favourite_question')
