Django ModelForm

一、ModelForm示例

Model

from django.db import models
from django.core.validators import *

# Create your models here.
class UserInfo(models.Model):
    uname = models.CharField(
        max_length=20,
        verbose_name='姓名',
        error_messages={
            'c1': '优先错信息1',
            'c2': '优先错信息2',
        },
        validators=[
            RegexValidator(regex='root_\d+', message='错误了', code='c1'),
            RegexValidator(regex='root_112233\d+', message='又错误了', code='c2'), ])
    upwd = models.CharField(max_length=40,verbose_name='密码')
    uemail = models.EmailField(verbose_name='邮箱')
    ushou = models.CharField(max_length=20, default='',verbose_name='收件人')
    uaddress = models.CharField(max_length=100, default='',verbose_name='地址')
    uyoubian = models.CharField(max_length=6, default='',verbose_name='邮编')
    uphone = models.CharField(max_length=11, default='',verbose_name='电话')

    def __str__(self):
        return self.uname

    class Meta:
        db_table = 'userinfo'

ModelForm

#forms.py
from django import forms
from .models import *
class UserInfoForm(forms.ModelForm):
    class Meta:
        model = UserInfo
        #fields = '__all__'
        fields = ['uname','upwd','uemail']
        labels = {                          # label 名称
            'uname': '用户名',
        }
        help_texts = {                     # 帮助信息
            'uname': '...'
        }
        widgets = {
            'uname': forms.TextInput()
        }
        error_messages = {                       # 自定义错误
            '__all__':{

            },
            'email': {
                'required': '邮箱不能为空',
                'invalid': '邮箱格式错误..',
            }
        }
        field_classes = {                         #字段类型，可以强制修改成其他类型
            # 'email': Ffields.URLField
        }
