Django的form（和model）验证器

from django.core import validators
from django import forms
from django.core.exceptions import ValidationError
import datetime

def validate_recharge(value):
    min_value = 5000
    if value < min_value:
        raise ValidationError(‘油卡充值金额必须大于%s‘ % min_value)
    now = datetime.datetime.now()
    if now.hour > 22 or now.hour < 2:
        raise ValidationError(‘中石化系统正在结算，暂时无法充值‘)
        
class Test_Form(forms.Form):
    recharge = forms.FloatField(validators=[validate_recharge])  # 通过字段的validators参数传递给字段FloatField的构造函数
    
    
from django.db import models

class MyModel(models.Model):
    recharge = models.IntegerField(validators=[validate_recharge])
