向同一个模型的外键反向关联名称产生了冲突 一个模型中有两个外键指向同一张表时,创建迁移模型时报错:" HINT: Add or change a related_name argument to the definition for 'AnswersModel.author' or 'AnswersModel.relay_to'."解决方案 class AnswersModel(models.Model): author = models.ForeignKey(FrontUserMod
先用文档中的样例: Models定义: class Album(models.Model): album_name = models.CharField(max_length=100) artist = models.CharField(max_length=100) class Track(models.Model): album = models.ForeignKey(Album, related_name='tracks', on_delete=models.CASCADE) order
class AnswersModel(models.Model): author = models.ForeignKey(FrontUserModel,null=True,related_name='answers_user') -- relay_to = models.ForeignKey(FrontUserModel,null=True,related_name='relay_to_user')当模型执行迁移时会报:HINT: Add or change a related_name arg
