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

class Case(BaseModel):
    '''用例表'''
    title = models.CharField(verbose_name='用例标题', max_length=100)
    project = models.ForeignKey(Project, on_delete=models.DO_NOTHING, db_constraint=False, verbose_name='归属项目')
    interface = models.ForeignKey(Interfaces, on_delete=models.DO_NOTHING, db_constraint=False, verbose_name='接口')
    user = models.ForeignKey(User, on_delete=models.DO_NOTHING, db_constraint=False, verbose_name='创建用户')
    method_choice = (
        (1, 'POST'),
        (2, 'GET'),
        (3, 'DELETE'),
        (4, 'PUT'),
    )
    method = models.SmallIntegerField(choices=method_choice, verbose_name='请求方式')
    cache_field = models.CharField(verbose_name='缓存字段', max_length=128, null=True, blank=True)
    checks = models.CharField(verbose_name='校验点', max_length=512)
    params = models.CharField(verbose_name='请求参数', max_length=2048, null=True, blank=True)
    headers = models.CharField(verbose_name='请求头信息', max_length=2048, null=True, blank=True)
    is_json = models.BooleanField(verbose_name='参数是否是json', default=False)
    json = models.CharField(verbose_name='json类型参数', max_length=2048, null=True, blank=True)
    status_choice = (
        (1, '通过'),
        (2, '未运行'),
        (3, '运行中'),
        (999, '失败')
    )
    status = models.SmallIntegerField(choices=status_choice, verbose_name='用例状态',
                                      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
    report_batch = models.CharField(verbose_name='最后一次执行的批次号', null=True, max_length=512, blank=True)

 

 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
