如何使用弹出式模态引导程序从链接运行函数

Question

我有一个django项目，其中包含一个弹出模式，该模式中的模式将选项卡链接为这些选项卡之一，用户单击它必须执行功能并从数据库中检索数据。

问题是，一旦用户单击选项卡，功能就不会初始化，也不会初始化。

urls.py

path("events/<int:id>/", getEvents, name = "getEvents"),

views.py

def getEvents(request,id):
    q1 = cursor.execute('SELECT Person_.ID FROM Person_ WHERE Person_.ID = {0}'.format(id))
    print('q1==>',q1)
    qresult = q1.fetchone()
    print("qresult==>",qresult)
    print("query is not empty!")
    eventQ = cursor.execute('SELECT Person_.ID, Person_.Full_Name, Events.ID, Events.Event_Title, Events.Event_Details, Links.document_id from Person_, Events, Links where  ( Person_.ID = {0}) and (Person_.ID = Links.A_Person or Person_.ID = Links.B_Person) and (Events.ID = Links.A_Event or Events.ID = Links.B_Event) ORDER BY Events.ID DESC '.format(id))

    resultEvents = eventQ.fetchall()
    return render(request,'pictureCard.html',{
                            "resultEvents":resultEvents,
                            "qresult":qresult,

                            })

Answer 1

可能django不知道{object_list％中的obj的％}。因为您要发送2个变量，分别是resultEvents和qresult，但是您的html文件正在查找“ object_list”字典或列表。这可能是问题所在。

希望这会有所帮助，
