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">

    <title></title>

<body>
    <h1>恭喜{{username}},登陆成功~</h1>
</form>
</body>
</html>

  <style type="text/css">

    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)
