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>
                <th>公司</th>

                {% if "customer_edit"|has_permission:request%}
                 <th>编辑</th>
                {% endif %}
                {% if "customer_del"|has_permission:request %}
                 <th>删除</th>
                {% endif %}
            </tr>
            </thead>
            <tbody>
            {% for row in data_list %}
                <tr>
                    <td>{{ row.id }}</td>
                    <td>{{ row.name }}</td>
                    <td>{{ row.age }}</td>
                    <td>{{ row.email }}</td>
                    <td>{{ row.company }}</td>

                        {% if "customer_edit"|has_permission:request  %}
                               <td>
                                <a style="color: #333333;" href="/customer/edit/{{ row.id }}/">
                                    <i class="fa fa-edit" aria-hidden="true"></i>
                                </a>
                                </td>
                        {% endif %}

                        {% if "customer_del"|has_permission:request  %}
                               <td>
                                <a style="color: #d9534f;" href="/customer/del/{{ row.id }}/">
                                    <i class="fa fa-trash-o"></i>
                                </a>
                               </td>
                        {% endif %}


                </tr>
            {% endfor %}
            </tbody>
        </table>
    </div>
{% endblock %}

4.引用的web

from django.utils.safestring import mark_safe
from django.template import Library
import re
register =Library()


@register.inclusion_tag("rbac/menu.html")
def get_menu_styles(request):
    permission_menu_dict = request.session.get("permission_menu_dict")
    print("permission_menu_dict",permission_menu_dict)

    for val in permission_menu_dict.values():
        for item in val["children"]:
            val["class"]="hide"

            ret=re.search("^{}$".format(item["url"]),request.path)
            if ret:
                val["class"] = ""

    return {"permission_menu_dict":permission_menu_dict}






@register.filter
def has_permission(btn_url,request):
    permission_names = request.session.get("permission_names")

    return btn_url in permission_names
