submit a task after webpage report an error no “batch_pattern”

[tonyjia87]

修改tars/api/seriailzers/deployment.py 的validate_batch_pattern。
估计开源版本抹去了验证，但是代码维护出现问题

建议

    def validate_batch_pattern(self, pattern_str):
        return  pattern_str

        # validator = self.Meta.model.deployment.related.model._meta\
        #     .batch_factory.validate_batch_pattern
        # try:
        #     return validator(pattern_str)
        # except Exception as e:
        #     raise ValidationError(e)
