  • django 不能直接把列表给模板 TypeError: context must be a dict rather than tuple.

     将list 传递到前台模板:
     
     举例:
    
    views.py
    
    return render(request,'index.html',list)
    
    def viewtbs(req):
       conn= MySQLdb.connect(
            host='127.0.0.1',
            port = 3306,
            user='root',
            passwd='1234567',
            db ='DEVOPS',
            charset="UTF8"
            )
       cursor = conn.cursor()
       a = cursor.execute("select sn,ip,info,env,script from publish_info;" )
       info = cursor.fetchall()
       print info
       print type(info)
       return render(req,'viewtbs.html',info)
       
    TypeError at /polls/test002/
    
    context must be a dict rather than tuple.
    
    <type 'tuple'>
