如何从弹出模式引导程序中的链接运行函数

Question

我有一个包含弹出模式的django项目。模式具有选项卡作为链接。当用户单击其中一个选项卡时，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，就没有任何反应，并且函数没有初始化。

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 {% for obj in object_list %}。因为您正在发送 2 个变量，它们是 resultEvents 和 qresult，但您的 html 文件正在寻找"object_list"字典或列表。这可能是问题所在。

希望这有帮助，
