}Django models 中，建立 模型： （这一步很重要！！！）
– 建立好后，记得用 makemigrations 和 migrate 同步一下！！
from django.db import models
class Permission(models.Model):
class Meta:
#权限信息，这里定义的权限的名字，后面是描述信息，描述信息是在django admin中显示权限用的
permissions = (
('views_slg_users_tem', '查看玩家管理'),
('views_slg_alliance_tem', '查看联盟管理'),
('views_slg_mail_notice_tem', '查看公告邮件'),
('views_slg_order_tem', '查看订单系统'),
('views_slg_reward_tem', '查看礼包奖励'),
('views_slg_service_reply_tem', '查看客服反馈'),
('views_slg_user_log_tem', '查看玩家日志'),
('views_slg_server_tem', '查看服务器管理'),
('views_slg_manager_tem', '查看管理员管理'),
)
建立好后，数据库表(auth_permission)类似于这样： （id 那一列，很重要！！我们后面添加权限要用到的！！）
后端python–views视图：
from django.contrib.auth.decorators import login_required, permission_required
from django.contrib.auth.models import User
from django.views.decorators.http import require_http_methods
from django.http import HttpResponse
from django.shortcuts import render
from slg.models.slg.slg_manager_tem import db_change_permission)
# 修改权限
@login_required(login_url='slg:login')
@require_http_methods(["POST"])
@permission_required('slg.views_slg_manager_tem', login_url='slg:get_permissionDenied')
def change_permission(request):
permissionsList = [
'views_slg_users_tem',
'views_slg_mail_notice_tem',
'views_slg_order_tem',
'views_slg_reward_tem',
'views_slg_service_reply_tem',
'views_slg_user_log_tem',
'views_slg_server_tem',
'views_slg_manager_tem'
]
username = request.POST['username']
permissions = request.POST['permissions'].split(', ')
if permissions[0] != '': # 不为空时
for index, value in enumerate(permissions):
permissions[index] = permissionsList[int(value)] # 将 数字 替换为 上面数组中的 字符串
print(permissions)
else:
permissions = []
changeResult = db_change_permission(username, permissions)
return HttpResponse(changeResult)后端python–models视图：
from django.contrib.auth.models import User
from django.contrib.auth import authenticate
from django.db.utils import IntegrityError
from . import db_models as db
# 修改权限
def db_change_permission(username, permissions):
try:
user = User.objects.get(username=username)
if permissions:
pers = []
for per in permissions:
db_per = db.AuthPermission.objects.filter(codename=per).values('id')[0]['id'] # 只把 id 取出来
pers.append(db_per)
#print(pers) # 形如： [147, 150, 152] 数字为 auth_permission 中的 id
user.user_permissions = pers # 这里，只能 加 id，加 codename 是不行的！！！
else:
user.user_permissions.clear()
User.objects.get(username=username) # 刷新 缓存
#print(user.get_all_permissions())
except Exception:
return -1
else:
return 1 # 修改成功
错误页面相关： （它是类似于：403， 404 等页面的汇总，也需要设置相关路由）
permissionDenied.html：
<!DOCTYPE html>
<html lang="en">
{% load staticfiles %}
<head>
<meta charset="UTF-8">
<title>403</title>
</head>
<body>
<h1>403</h1>
<h2>You don't have enought permissions to this action!</h2>
</body>
</html>view视图：
from django.contrib.auth.decorators import login_required
from django.views.decorators.http import require_http_methods
from django.shortcuts import render
# GET 渲染 403页面
@login_required(login_url='slg:login')
@require_http_methods(["GET", "POST"])
def get_permissionDenied(request):
return render(request, 'slg/permissionDenied.html')url路由：
'''总路由，路由分发地'''
from django.conf.urls import url, include
urlpatterns = [
url(r'^', include('slg.urls.slg.error')), # 错误页面 相关路由
]
'''子路由，这里进入具体的html页面'''
from django.conf.urls import url
from slg.views.slg import error
urlpatterns = [
url(r'^permissionDenied$', error.get_permissionDenied, name='get_permissionDenied'), # 403页面
]
正常页面的 权限设置：
base.html：（模板页面，所有页面都继承于此）
{% if 'slg.views_slg_users_tem' in perms %} {# 判断 是否 有访问权限，没有的话，就不显示该菜单 #}
<li role="presentation" class="main-menu" id="top_one">
<a href="{% url 'slg:get_slg_users_tem' %}" rel="external nofollow" style="margin-left: 5px;"><span class="glyphicon glyphicon-fire"></span>玩家管理</a>
</li>
{% endif %}
其他 veiws视图 中的设置：
from django.contrib.auth.decorators import login_required, permission_required
from django.contrib.auth.models import User
from django.views.decorators.http import require_http_methods
from django.shortcuts import render
# GET 渲染页面 （其他的POST请求中，最好也加入 @permission_required 用来限制访问）
@login_required(login_url='slg:login')
@require_http_methods(["GET"])
@permission_required('slg.views_slg_users_tem', login_url='slg:get_permissionDenied') #权限装饰器
def get_users_tem(request):
perms = User.get_all_permissions(request.user) #获取 访问请求 用户的 所有权限
context = {"perms": perms}
return render(request, 'slg/slg_users_tem.html', context=context)
