django 快速实现登陆，接着注册的项目写（五）

1.改项目的urls.py

from django.conf.urls import url,include

from django.contrib import admin

admin.autodiscover()

urlpatterns = [

    url(r'^admin/', admin.site.urls),

	url(r'^account/', include('account.urls')),

]

　改应用的urls.py

from django.conf.urls import url

from account import views

urlpatterns=[

    #url(r'^$',views.register,name='register'),

	url(r'^register/$',views.register,name='register'),

	url(r'^login/$',views.login,name='login'),

                     ]

　　修改view.py

from __future__ import unicode_literals

from django.shortcuts import render,render_to_response

from django.template import loader,Context

from django.http import HttpResponse

from django import forms

from account.models import User

# Create your views here.

#定义表单模型 —— 在页面上显示的输入框

class UserForm(forms.Form):

    username=forms.CharField(label='用户名：',max_length=100)

    password=forms.CharField(label='密码：',widget=forms.PasswordInput())

    email=forms.EmailField(label='电子邮件：')

class User2Form(forms.Form):

	username=forms.CharField(label='用户名：',max_length=100)

	password=forms.CharField(label='密码：',widget=forms.PasswordInput())

#注册

def register(request):

    if request.method=='POST':

        uf=UserForm(request.POST)

        if uf.is_valid():

            #获取表单信息

            username=uf.cleaned_data['username']

            password=uf.cleaned_data['password']

            email=uf.cleaned_data['email']

            #将表单数据写入数据库

            user=User()

            user.username=username

            user.password=password

            user.email=email

            user.save()

            #返回注册成功页面

            return render_to_response('success.html',{'username':username})

    else:

        uf=UserForm()

    return render_to_response('register.html',{'uf':uf})

#登陆

def login(request):

	if request.method=='POST':

		uf =User2Form(request.POST)

		if uf.is_valid():

			#获取表单用户密码

			username=uf.cleaned_data['username']

			password=uf.cleaned_data['password']

			#获取的表单数据与数据库做比较

			user=User.objects.filter(username__exact=username,password__exact=password)

			if user:

				return render_to_response('success_login.html',{'username':username})

			else:

				return render_to_response('login.html',{'uf':uf})

	else:

		uf=User2Form()

	return render_to_response('login.html',{'uf':uf})

　　增加模板：
success_login.html

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<head>

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

    <title></title>

</head>

<body>

    <h1>恭喜{{username}},登陆成功~</h1>

</form>

</body>

</html>

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">

<head>

    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />

    <title>用户登陆</title>

</head>

  <style type="text/css">

    body{color:#efd;background:#453;padding:0 5em;margin:0}

    h1{padding:2em 1em;background:#675}

    h2{color:#bf8;border-top:1px dotted #fff;margin-top:2em}

    p{margin:1em 0}

  </style>

<body>

<h1>登陆：</h1>

<form method = 'post' enctype="multipart/form-data">

{{uf.as_p}}

<input type="submit" value = "ok" />

</form>

</body>

</html>

model使用之前的，没有变化

# -*- coding: utf-8 -*-

from __future__ import unicode_literals

from django.db import models

from django.contrib import admin

# Create your models here.

class User(models.Model):

    username=models.CharField(max_length=50)

    password=models.CharField(max_length=50)

    email=models.EmailField()

class UserAdmin(admin.ModelAdmin):

	list_display=('username','email')

admin.site.register(User,UserAdmin)
