报错解决：user.Case: (models.E020) The 'Case.check()' class method is currently overridden by

Django在启动时报错，如下：

user.Case: (models.E020) The 'Case.check()' class method is currently overridden by <django.db.models.query_utils.DeferredAttribute object at 0x0000020331E0AE20>.

意思是说：在user.Case.check()在执行的过程中被【django.db.models.query_utils.DeferredAttribute】覆盖了

27                                       default=2)  # 记录上一次的状态 每次执行后需要更新下这个表的这个字段

 通过尝试注释15行后，是不报错的，但是这样也不行，还有使用这个参数，尝试了check末尾+s，结果正常了
