django=2.2.3 mariadb
从具有“inspectdb”的现有数据库导入模型并更改字段属性后,会发生此错误。
class Post(models.Model):
post_id = models.AutoField(primary_key=True)
post_name = models.CharField(max_length=255, blank=True, null=True)
email = models.CharField(max_length=255, blank=True, null=True)
class Rank(models.Model):
rank_id = models.AutoField(primary_key=True)
rank_type = models.IntegerField(blank=True, null=True)
created_at = models.DateTimeField()
# post_id = models.IntegerField(blank=True, null=True)
post_id = models.ForeignKey(Post, on_delete=models.SET_NULL, blank=True, null=True)
原来是#post_id,但是我去掉了“managed = False”,改成了ForeignKey,然后“迁移”了。据我所知,如果“Post”模型中的“post_id”是“primary_key True”,它会将“id”值替换为“post_id”。但是“Django”不断调用“post_id_id”。没有命令可以在别处引用 post_id_id。如果您有解决方案或我缺少的东西,请给我一些建议。
