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),

]
