示例：
# -----
from django.core.exceptions import ValidationError
def validate_even(value):
if value % 2 != 0:
raise ValidationError('%s is not an even number' % value)
# ----
from django.db import models
class MyModel(models.Model):
even_field = models.IntegerField(validators=[validate_even])
# -----
from django import forms
class MyForm(forms.Form):
even_field = forms.IntegerField(validators=[validate_even])
自定义异常返回
raise serializers.ValidationError(detail={"code": "403", "message": "权限不足"})
