权限注入：
from rbac import models def initial_session(request,user_obj): permission_obj = models.Permission.objects.filter(role__user=user_obj).distinct() # print(permission_obj) permission_list = [] permission_menu_list = [] for item in permission_obj: permission_list.append(item.url) if item.is_menu: permission_menu_list.append({‘title‘:item.title,‘url‘:item.url,‘icon‘:item.icon}) # permission_list = [i.url for i in permission_obj] request.session[‘permission_list‘] = permission_list request.session[‘permission_menu_list‘] = permission_menu_list
方式一：直接循环标签生成html标签
{% for foo in request.session.permission_menu_list %}
<div>
<i class="fa {{ foo.icon }}"></i>
<a href="{{ foo.url }}">{{ foo.title }}</a>
</div>
{% endfor %}
方式二：通过自定义的标签， 生成html标签返回给页面
在主页面中引入
{% load rbac %}
{% menu request %}
templatetags-->rbca.py
from django import template register = template.Library() import re @register.inclusion_tag(‘rbac/menu.html‘) def menu(request): menu_list = request.session.get(‘permission_menu_list‘) for item in menu_list: url = item[‘url‘] if re.match(‘{}‘.format(url),request.path_info): item[‘active‘] = ‘active‘ break return {‘menu_list‘:menu_list}
templates-->rbca-->menu.html
<div class="static-menu"> {% for item in menu_list %} {% if item.active %} #判断当前标签是否是选中标签，添加active属性 <a href="{{ item.url }}" class="{{ item.class }} active"> <span class="icon-wrap"><i class="fa {{ item.icon }}"></i></span> {{ item.title }}</a> {% else %} <a href="{{ item.url }}" class="{{ item.class }} "> <span class="icon-wrap"><i class="fa {{ item.icon }}"></i></span> {{ item.title }}</a> {% endif %} {% endfor %} </div>
