给django

1. 在表格的下方添加一个链接【显示/隐藏列】

【显示/隐藏列】

2. 用javascript写一段函数

3. 后端写一个接view.py

def showhidecolumns(request):

    initial_list = ['host_name', 'service_tag','motable__hosttype_list__name','motable','receive_date','user_list__dept_list__bl_list__bl_name','user_list__dept_list__dept_name','user_list', 'pcstatustable', 
                                                            'site_list','asset_code','ownername','user_list__work_category__name']
    if request.method == 'GET':
            includes_list=request.session.get('includes_list',[])
            if len(includes_list) > 0:
                initial_list = includes_list
            columns_list = request.session.get('columns_list_session')
            #print(columns_list)

            obj = showhidecolumnsform(request,initial={'sh':initial_list})

            return render(request, 'showhidecolumns.html' ,{'obj':obj})
    else:
        obj = request.POST.getlist('sh')
        request.session['includes_list']=obj
        #print('obj',obj)
        excludes = request.session.get('columns_list_session')
        excludes_dict = dict(excludes)
        for i in obj:
            #print(str(i))
            del excludes_dict[i]
        #print(tuple(excludes_dict.keys()))
        request.session['excludes_list'] = tuple(excludes_dict.keys())
        return HttpResponse('

 设置成功!')
