Layui后台布局：

一、后台布局之顶边栏

<div class="layui-header">
        <div class="layui-logo">layui 后台布局</div>
        <!-- 头部区域（可配合layui已有的水平导航） -->
        <ul class="layui-nav layui-layout-left">
            <li class="layui-nav-item"><a href="">控制台</a></li>
            <li class="layui-nav-item"><a href="">商品管理</a></li>
            <li class="layui-nav-item"><a href="">用户</a></li>
            <li class="layui-nav-item">
                <a href="javascript:;">其它系统</a>
                <dl class="layui-nav-child">
                    <dd><a href="">邮件管理</a></dd>
                    <dd><a href="">消息管理</a></dd>
                    <dd><a href="">授权管理</a></dd>
                </dl>
            </li>
        </ul>
        <ul class="layui-nav layui-layout-right">
            <li class="layui-nav-item">
                <a href="javascript:;">
                    <img src="http://t.cn/RCzsdCq" class="layui-nav-img">
                    {{request.user.username}}
                </a>
                <dl class="layui-nav-child">
                    <dd><a href="">基本资料</a></dd>
                    <dd><a href="">安全设置</a></dd>
                </dl>
            </li>
            <li class="layui-nav-item"><a href="">退了</a></li>
        </ul>
    </div>

代码中橙色背景的一行为Django中传入的当前登录用户的用户名。

最终效果如下：

二、后台布局之侧边栏

侧边栏由于需要动态加载节点和子节点，所以需要先在Django中建立节点和子节点的model，model代码如下：

# 节点类
class NavigationProfile(models.Model):
    name=models.CharField(max_length=20,verbose_name='节点名称')
    url=models.CharField(max_length=50,verbose_name='链接地址')
    iconCls=models.CharField(max_length=50,verbose_name='图标icon')
 
    class Meta:
        verbose_name='节点名称'
        verbose_name_plural=verbose_name
 
    def __str__(self):
        return self.name
 
# 子节点类
class NavigationSubProfile(models.Model):
    name=models.CharField(max_length=20,verbose_name='子节点名称')
    url=models.CharField(max_length=50,verbose_name='链接地址')
    iconCls=models.CharField(max_length=50,verbose_name='图标icon')
    parent=models.ForeignKey(NavigationProfile,on_delete=models.CASCADE,verbose_name='父节点')
 
    class Meta:
        verbose_name='子节点名称'
        verbose_name_plural=verbose_name
 
    def __str__(self):
        return self.name

在Django views中代码如下：

def open_index(request):
    if request.user.is_authenticated == False:
        return HttpResponseRedirect('/account/login/')
    else:
        navigation = NavigationProfile.objects.all()
        dict = []
 
        for nav in navigation:
            dic = {}
            id = nav.id
            dic['id'] = nav.id
            dic['text'] = nav.name
            dic['url'] = nav.url
            dic['iconCls'] = nav.iconCls
            dic['nid'] = 0
            sub_navigation = NavigationSubProfile.objects.filter(parent_id=id)
 
            sub_dict = []
            for sub_nav in sub_navigation:
                sub_dic = {}
                sub_dic['id'] = sub_nav.id
                sub_dic['text'] = sub_nav.name
                sub_dic['url'] = sub_nav.url
                sub_dic['iconCls'] = sub_nav.iconCls
                sub_dic['nid'] = sub_nav.parent_id
                sub_dict.append(sub_dic)
 
            dic["children"] = sub_dict
            dict.append(dic)30         return render(request,'index.html',{'dict':dict})

Django urls代码如下：

urlpatterns = [
    path('get-navigationProfile/',views.get_navigationProfile,name='get_navigationProfile'),
]

Html侧边栏代码如下：

<div class="layui-side layui-bg-black">
        <div class="layui-side-scroll">
            <!-- 左侧导航区域（可配合layui已有的垂直导航） -->
            <ul class="layui-nav layui-nav-tree" lay-filter="test">
 
                {% for dic in dict %}
                    <li class="layui-nav-item">
                        <a class="" href="javascript:;">{{ dic.text }}</a>
                        <dl class="layui-nav-child">
                            {% for child in dic.children %}
                                <dd><a href="javascript:;" data-id="{{ child.id }}"
                                       data-url="{{ child.url }}">{{ child.text }}</a></dd>
                            {% endfor %}
 
                        </dl>
                    </li>
                {% endfor %}
 
            </ul>
        </div>
    </div>
