Django models 中,建立 模型: (這一步很重要!?。。?
– 建立好后,記得用 makemigrations 和 migrate 同步一下!!
from django.db import models class Permission(models.Model): class Meta: #權(quán)限信息,這里定義的權(quán)限的名字,后面是描述信息,描述信息是在django admin中顯示權(quán)限用的 permissions = ( ('views_slg_users_tem', '查看玩家管理'), ('views_slg_alliance_tem', '查看聯(lián)盟管理'), ('views_slg_mail_notice_tem', '查看公告郵件'), ('views_slg_order_tem', '查看訂單系統(tǒng)'), ('views_slg_reward_tem', '查看禮包獎勵'), ('views_slg_service_reply_tem', '查看客服反饋'), ('views_slg_user_log_tem', '查看玩家日志'), ('views_slg_server_tem', '查看服務(wù)器管理'), ('views_slg_manager_tem', '查看管理員管理'), )
建立好后,數(shù)據(jù)庫表(auth_permission)類似于這樣: (id 那一列,很重要??!我們后面添加權(quán)限要用到的!?。?/p>
后端python–views視圖:
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) # 修改權(quán)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] != '': # 不為空時 for index, value in enumerate(permissions): permissions[index] = permissionsList[int(value)] # 將 數(shù)字 替換為 上面數(shù)組中的 字符串 print(permissions) else: permissions = [] changeResult = db_change_permission(username, permissions) return HttpResponse(changeResult)
后端python–models視圖:
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 # 修改權(quán)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 取出來 pers.append(db_per) #print(pers) # 形如: [147, 150, 152] 數(shù)字為 auth_permission 中的 id user.user_permissions = pers # 這里,只能 加 id,加 codename 是不行的?。?! else: user.user_permissions.clear() User.objects.get(username=username) # 刷新 緩存 #print(user.get_all_permissions()) except Exception: return -1 else: return 1 # 修改成功
錯誤頁面相關(guān): (它是類似于:403, 404 等頁面的匯總,也需要設(shè)置相關(guān)路由)
permissionDenied.html:
<!DOCTYPE html> <html lang="en"> {% load staticfiles %} <head> <meta charset="UTF-8"> <title>403</title> </head> <body> <h2>403</h2> <h3>You don't have enought permissions to this action!</h3> </body> </html>
view視圖:
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頁面 @login_required(login_url='slg:login') @require_http_methods(["GET", "POST"]) def get_permissionDenied(request): return render(request, 'slg/permissionDenied.html')
url路由:
'''總路由,路由分發(fā)地''' from django.conf.urls import url, include urlpatterns = [ url(r'^', include('slg.urls.slg.error')), # 錯誤頁面 相關(guān)路由 ]
'''子路由,這里進入具體的html頁面''' from django.conf.urls import url from slg.views.slg import error urlpatterns = [ url(r'^permissionDenied$', error.get_permissionDenied, name='get_permissionDenied'), # 403頁面 ]
正常頁面的 權(quán)限設(shè)置:
base.html:(模板頁面,所有頁面都繼承于此)
{% if 'slg.views_slg_users_tem' in perms %} {# 判斷 是否 有訪問權(quán)限,沒有的話,就不顯示該菜單 #} <li role="presentation" class="main-menu" id="top_one"> <a href="{% url 'slg:get_slg_users_tem' %}" rel="external nofollow" ><span class="glyphicon glyphicon-fire"></span>玩家管理</a> </li> {% endif %}
其他 veiws視圖 中的設(shè)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 渲染頁面 (其他的POST請求中,最好也加入 @permission_required 用來限制訪問) @login_required(login_url='slg:login') @require_http_methods(["GET"]) @permission_required('slg.views_slg_users_tem', login_url='slg:get_permissionDenied') #權(quán)限裝飾器 def get_users_tem(request): perms = User.get_all_permissions(request.user) #獲取 訪問請求 用戶的 所有權(quán)限 context = {"perms": perms} return render(request, 'slg/slg_users_tem.html', context=context)
