我有一个带有导航栏的Django网站，我需要在其中显示用户以及该用户所属的组，以使此信息在所有页面上可见。

直到现在，我都可以将这些数据项发送到特定页面，但不能发送到页眉。

views.py

def home(request):

 #print(User.groups.get())
 print(request.session.keys())
 if request.session.has_key('theUser'):
  authed=request.session['theUser']
  if request.session.has_key('group'):
   sections=request.session['group']
   return render(request,'./mainpage.html',{'sections':sections,'authed':authed})
  else:
   authed=None
 else:
  authed=None

 return render(request,'./Login.html',{'authed':authed})

我要发送 {'sections'：sections，'authed'：authed} 的位置到 mainpage.html

mainpage.html

<div id='left-column-Input' class="formInput" include="select()">
        {{user.get_username}}|{{sections}}

我需要将数据发送到标头或基本文件。

base.html

<!DOCTYPE html>
{% load static %}

<html>

    <head>
        <script type="text/javascript" src="{% static '/js/jquery-3.1.1.min.js' %}"></script>

            {% endif %} </th>
