django 权限设置-登录配置权限

1.首先需要一个判断用户是否拥有这个权限的name来区分在主页上是否显示标签

在permission中加入

name=models.CharField(max_length=32, verbose_name='url别名',default="")

2.在rabc.py 中加入一个空列表,用来存放关联的permission__name 来区分

左后注入session中

request.session["permission_names"] = permission_names

3.

在标签处写入判断

 {% extends 'web/layout.html' %}

 {% block content %}

     <div class="luffy-container">
         <div class="btn-group" style="margin: 5px 0">
             {% load web %}
             {% if "customer_add"|has_permission:request %}
                  <a class="btn btn-default" href="/customer/add/">
                     <i class="fa fa-plus-square" aria-hidden="true"></i> 添加客户
                  </a>
             {% endif %}

         </div>
         <table class="table table-bordered table-hover">
             <thead>
             <tr>
                 <th>ID</th>
                 <th>客户姓名</th>
                 <th>年龄</th>
                 <th>邮箱</th>

                 {% if "customer_edit"|has_permission:request%}
                  <th>编辑</th>
                 {% endif %}

                  <th>删除</th>
                 {% endif %}
             </tr>
             </thead>
             <tbody>
             {% for row in data_list %}
                 <tr>
                     <td>{{ row.id }}</td>
                     <td>{{ row.name }}</td>
