如何在django中構建一個voto問題數據庫？

Question

我想跟蹤哪些問題，並回答用戶投票（上下），所以這是我做到了，它不工作

這是我的問題類

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) 

這是我USERPROFILE類（擴展用戶）

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) 

如果取消對該行 運行synvdb命令，它會顯示錯誤

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' 

和其餘4行顯示相同的錯誤。我真的很新的Django，請幫助

關於錯誤，你必須定義相關的名字，如果你想使用相同類型的模型之間的關係：

例如：

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