最近完成这样的一个需求，比如说一个网页有几个按钮（添加，编辑，删除，查看），张三用户可以访问这几个按钮，李四只能查看（没有其它权限），怎么办？我相信对于初学者来说，完成这样的需求，确实有点难度，作者也是折腾了2天，才懂的一点皮毛，在这里非常感谢我的同事雪姐，耐心的给我讲解。言归正传，把这个流程跟大家分享一下.(高手勿喷)

首先设计表结构
创建一个用户表，并且做了一对一关联django user表
1.自定义用户表
from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
#自定义用户表
class Userinfo(models.Model):
user = models.OneToOneField(User) #关联django user表
username = models.CharField(max_length=100)
password = models.CharField(max_length=100)
def __unicode__(self):
return self.username
2.自定义权限表
class quanxian(models.Model):
shuoming=models.CharField(max_length=100)
def __unicode__(self):
return self.shuoming
class Meta:
permissions = (
('edit', u'编辑权限'),
('add', u'添加权限'),
('DEL',u'删除权限'),
('list',u'查看权限'),
)3.views.py定义一个login视图方法
from test01.models import Userinfo
from django import forms
from django.contrib import auth
from django.contrib.auth.models import User
from django.contrib.auth import authenticate
from django.template import RequestContext
# Create your views here.
class UserForm(forms.Form):
username = forms.CharField(label="user",max_length=100)
password = forms.CharField(label="passwd",widget=forms.PasswordInput())
def index(request):
return render_to_response('index.html')
def login(request):
if request.method == 'POST':
uf = UserForm(request.POST)
if uf.is_valid():
username = uf.cleaned_data['username']
password = uf.cleaned_data['password']
print username,password,"[*******]"
user1 = authenticate(username=username, password=password)
is_add = True if user1.has_perm('test01.add') else False
print 'user1--->',user1,user1.has_perm('test01.add'), is_add
if user1:
return render_to_response('index.html',locals(), context_instance=RequestContext(request))
else:
return HttpResponseRedirect('/login/')
else:
uf = UserForm()
return render_to_response('login.html',{'uf':uf})4.在admin.py注册models.py里的表
from django.contrib import admin
from test01 import models
admin.site.register(models.quanxian)
admin.site.register(models.Userinfo)
5.urls.py
from django.conf.urls import url
from django.contrib import admin
from test01 import views
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^index/$',views.index),
url(r'^$', views.login, name='login'),
]
6.初始化数据表，创建后台admin管理员
python manage.py makemigrations
python manage.py migrate
创建后台admin管理员
bogon:model_test will.xin$ python manage.py createsuperuser
Username (leave blank to use 'will.xin'): admin
Email address:
Password:
Password (again):
Superuser created successfully.
7.登录admin后台,创建用户
http://127.0.0.1:8000/admin/
8.前端页面
vim login.html
登录
登录页面：
`uf`.`as_p`
