HTML看我

from django.shortcuts import render,HttpResponse,redirect
from django import forms
from django.forms import fields
# Create your views here.
class F1Form(forms.Form):
    user = fields.CharField(max_length=18,
                            min_length=6,
                            required=True,
                            error_messages={
                                'required':'用户名不能为空',
                            })
    pwd = fields.CharField(min_length=32, required=True)
    age = fields.IntegerField(
        required=True,
        error_messages={
            'invalid':'必须为数字格式',
            'required':'年龄不能为空'
        }
    )
    email = fields.EmailField(
        required=True,
        error_messages={
            'invalid':'必须为邮件格式，带@的那种',
            'required': '邮箱不能为空'
        }
    )




def f1(request):
    if request.method =='GET':
        obj = F1Form()
        return render(request,'f1.html',{'obj':obj})
    else:
        # u = request.POST.get('user') #不能为空，长度6-18
        # p = request.POST.get('pwd')  #不能为空
        # e = request.POST.get('email') #邮箱格式
        # a = request.POST.get('age') #不能为空，必须为数字类型
        #
        # #1.检查是否为空
        # #2.检查格式是否正确
        # print(u,p,e,a)
        obj = F1Form(request.POST)
        #是否验证成功
        if obj.is_valid():
            #已经验证过的数据
            print('验证成功',obj.cleaned_data)
            return redirect('http://www.baidu.com')
        else:
            print('验证失败',obj.errors)
        return render(request,'f1.html',{'obj':obj})

Views看我

"""day58 URL Configuration

The `urlpatterns` list routes URLs to views. For more information please see:
    https://docs.djangoproject.com/en/2.0/topics/http/urls/
Examples:
Function views
    1. Add an import:  from my_app import views
    2. Add a URL to urlpatterns:  path('', views.home, name='home')
Class-based views
    1. Add an import:  from other_app.views import Home
    2. Add a URL to urlpatterns:  path('', Home.as_view(), name='home')
Including another URLconf
    1. Import the include() function: from django.urls import include, path
    2. Add a URL to urlpatterns:  path('blog/', include('blog.urls'))
"""
from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from app01 import views
from app02 import views as v2
urlpatterns = [
    path('admin/', admin.site.urls),
    url(r'^index.html$',views.index),
    url(r'^index1.html$', views.index1),
    url(r'^f1.html$', v2.f1),
]
