博客主页面之导航栏

前端代码

前端代码使用的是bootstrap框架.
技术点:
判断用户是否登录,登录和没有登录展示给用户的用户的页面是不一样的,这里用到了模板语言的if判断.

 {% if request.user.username %}

如果request的user的username不是空的话就展示注销等
否则展示登录或者注册,具体仔细看下面的代码

<nav class="navbar navbar-inverse">
    <div class="container-fluid">
        <!-- Brand and toggle get grouped for better mobile display -->
        <div class="navbar-header">
            <button type="button" class="navbar-toggle collapsed" data-toggle="collapse"
                    data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
                <span class="sr-only">Toggle navigation</span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
                <span class="icon-bar"></span>
            </button>
            <a class="navbar-brand" href="#">SpecYueBlog</a>
        </div>

        <!-- Collect the nav links, forms, and other content for toggling -->
        <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
            <ul class="nav navbar-nav ">
                <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>
                <li><a href="#">Link</a></li>
            </ul>
            <form class="navbar-form navbar-left">
                <div class="form-group">
                    <input type="text" class="form-control" placeholder="Search">
                </div>
                <button type="submit" class="btn btn-default">Submit</button>
            </form>
            <ul class="nav navbar-nav navbar-right">
                {% if request.user.username %}
                    <li><a href="#">{{ request.user.username }}</a></li>
                    <li class="dropdown">
                        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true"
                           aria-expanded="false">个人中心 <span class="caret"></span></a>
                        <ul class="dropdown-menu">
                            <li><a href="#">Action</a></li>
                            <li><a href="#">Another action</a></li>
                            <li><a href="#">Something else here</a></li>
                            <li role="separator" class="divider"></li>
                            <li><a href="/logout/">注销</a></li>
                        </ul>
                    </li>
                {% else %}
                    <li><a href="/login/">登录</a></li>
                    <li><a href="/reg/">注册</a></li>

                {% endif %}


            </ul>
        </div><!-- /.navbar-collapse -->
    </div><!-- /.container-fluid -->
</nav>

后端

后端没什么好配合的，只要写一个视图接受request，再把request用render函数传递到前端就好
