最近完成這樣的一個需求，比如說一個網頁有幾個按鈕（添加，編輯，刪除，查看），張三用戶可以訪問這幾個按鈕，李四只能查看（沒有其它權限），怎么辦？我相信對於初學者來說，完成這樣的需求，確實有點難度，作者也是折騰了2天，才懂的一點皮毛，在這里非常感謝我的同事雪姐，耐心的給我講解。言歸正傳，把這個流程跟大家分享一下.(高手勿噴)
首先設計表結構
創建一個用戶表，並且做了一對一關聯django user表
1.自定義用戶表
from __future__ import unicode_literals
from django.db import models
from django.contrib.auth.models import User
# Create your models here.
#自定義用戶表
class Userinfo(models.Model):
user = models.OneToOneField(User) #關聯django user表
username = models.CharField(max_length=100)
password = models.CharField(max_length=100)
def __unicode__(self):
return self.username
2.自定義權限表
class quanxian(models.Model):
shuoming=models.CharField(max_length=100)
def __unicode__(self):
return self.shuoming
class Meta:
permissions = (
('edit', u'編輯權限'),
('add', u'添加權限'),
('DEL',u'刪除權限'),
('list',u'查看權限'),
)
3.views.py定義一個login視圖方法
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注冊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.初始化數據表，創建后台admin管理員
python manage.py makemigrations
python manage.py migrate
創建后台admin管理員
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.登錄admin后台,創建用戶
點擊張三用戶，賦予張三用戶增加，編輯，刪除權限
李四用戶不給任何權限
8.前端頁面
vim 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>登錄</title>
</head>
<body>
<h1>登錄頁面：</h1>
<form method = 'post' enctype="multipart/form-data">
{{uf.as_p}}
<input type="submit" value = "ok" />
</form>
</body>
</html>
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>index</title>
</head>
<body>
{% if is_add %}
<button>編輯</button>
<button>添加</button>
<button>刪除</button>
{% else %}
<button>查看</button>
{% endif %}
<div>歡迎{{ username }} 登錄</div>
</body>
</html>
9.測試
首先用zhangsan用戶登錄
lisi用戶登錄后
大功告成
