03、 forms组件 - 爱码网

1、校验字段功能

1、reg页面准备

models

from django.db import models

class UserInfo(models.Model):
    useranme = models.CharField(max_length=32)
    password = models.CharField(max_length=32)
    email = models.EmailField()
    telephone = models.CharField(max_length=32)

生成数据表

C:\PycharmProjects\formsdemo>python manage.py makemigrations
C:\PycharmProjects\formsdemo>python manage.py migrate

主url

from django.contrib import admin
from django.urls import path, re_path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    re_path(r'^', include(('app01.urls', 'app01')))
]

url

from django.urls import path, re_path, include
from app01 import views

urlpatterns = [
    re_path(r'reg/$', views.reg, name='reg'),
]

模板层

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
<form action="" method="post">
    {% csrf_token %}
    <p>用户名 <input type="text" name="user"></p>
    <p>密码   <input type="password" name="pwd"></p>
    <p>确认密码 <input type="password" name="_pwd"></p>
    <p>邮箱   <input type="text" name="email"></p>
    <p>手机号 <input type="text" name="tel"></p>
    <input type="submit" value="注册">
</form>

</body>
</html>

view

from django.shortcuts import render, HttpResponse


def reg(request):
    if request.method == 'POST':
        print(request.POST)
        return HttpResponse('注册成功')

    return render(request, 'reg.html')

03、 forms组件

<QueryDict: {'csrfmiddlewaretoken': ['5EwZsUEKRVj836bplmS03PVruttZhG'], 'user': ['alex'], 'pwd': ['123'], '_pwd': ['123'], 'email': ['123@qq.com'], 'tel': ['1234566778']}>

2、定义规则

03、 forms组件

from django import forms   # 导入forms组件


# 定义校验规则
class UserForm(forms.Form):
    name = forms.CharField(min_length=4, max_length=10)
    email = forms.EmailField()
