4 首页获取当前登录用户

1. 
   

2. 方式一：
   前端request.user.is_authenticated()判断当前用户是否登录 
   
   

3. <form  class="form-signin" role="form" method='post'>
   

4.         <h3 class="form-signin-heading">Welcome!>

5.           {% if request.user.is_authenticated %}
   

6.             hihi: {{ request.user }} </br>
   

7.           <a href="{%   url 'log_out' %}">登出</a>
   

8.           {% endif %}

9. 
   

10.       </form>

方式二 将request.user.is_authenticated判断写入views视图再传入html中

1. @login_required
   

2. def index(request):
   

3.     if request.user.is_authenticated(): # 判断用户是否已登录
   

4.         user = request.user;
   

5.         return render_to_response('index.html', locals())
   

6. 
   

7. 
   

8. 
   

9.  <form  class="form-signin" role="form" method='post'>
   

10.         <h3 class="form-signin-heading">Welcome!>
    

11.              欢迎登录！{{ user }}

12.           <a href="{%   url 'log_out' %}">登出</a>
    

13.           
    

14. 
    

15.       </form>
