最近完成這樣的一個需求，比如說一個網(wǎng)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(quán)限），怎么辦？我相信對于初學者來說，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(shè)計表結(jié)構(gòu)
創(chuàng)建一個用戶表，并且做了一對一關(guān)聯(lián)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(guān)聯(lián)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(quán)限表
重慶分公司
重慶分公司
class quanxian(models.Model):
shuoming=models.CharField(max_length=100)
def __unicode__(self):
return self.shuoming
class Meta:
permissions = (
('edit', u'編輯權(quán)限'),
('add', u'添加權(quán)限'),
('DEL',u'刪除權(quán)限'),
('list',u'查看權(quán)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(shù)據(jù)表，創(chuàng)建后臺admin管理員
python manage.py makemigrations
python manage.py migrate
創(chuàng)建后臺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后臺,創(chuàng)建用戶
http://127.0.0.1:8000/admin/
8.前端頁面
vim login.html
