Django模型的clean方法多重错误 [英] Django model's clean method multiple error

问题描述

我一直在玩我的测试项目

I have been playing around with my test project

我的模型中有这种干净的方法

I have this clean method in my model

class SomeModel(models.Model):
    f1 = models.IntegerField()
    f2 = models.IntegerField()

    def clean(self):
        if self.f1 > self.f2:
            raise ValidationError({'f1': ['Should be greater than f1',]})
        if self.f2 == 100:
            raise ValidationError({'f2': ['That's too much',]})

我真的不知道如何引发这两个错误并将其显示在管理页面中，因为即使两个 if 为 True ，也只有第一个如果显示错误(很明显)，如何显示两个错误?

I don't really know how to raise both errors and show it in the admin page because even if the two if is True, only the first if error is shown(obviously) how do I show both errors?

推荐答案

您可以构建错误的 dict 并在完成时引发ValidationError(如有必要):

You could build a dict of errors and raise a ValidationError when you are done (if necessary):

class SomeModel(models.Model):
    f1 = models.IntegerField()
    f2 = models.IntegerField()

    def clean(self):
        error_dict = {}
        if self.f1 > self.f2:
             error_dict['f1'] = ValidationError("Should be greater than f1")  # this should probably belong to f2 as well
        if self.f2 == 100:
             error_dict['f2'] = ValidationError("That's too much")
        if error_dict:
             raise ValidationError(error_dict)
