我有一个型号名称Fightmma和一个名为Fightmmacard的模型。 Commentform适用于Fightcard，但不适用于Fightmma。
每张战斗卡都是由战斗组成的。当我评论任何战斗时，卡片上的最后一次战斗都会得到评论。
我的Commentform查找内容类型和ID。我无法正确地将正确的战斗ID传递给Commentform。在我的视图中，它通过战斗循环，但id仅存储为最后一次战斗。
我的python并不是那么棒，但我已经尝试了12个小时
所有帮助表示赞赏。
使用Django1.11

答案 0 :(得分：0)
将此添加到views.py
fightform = []
for fight in fightcard
initial_data = {
"content_type": fight.get_content_type,
"object_id": fight.id
}
Form[fight] = CommentForm(request.POST or None, initial=initial_data,)
if form.is_valid(): ### same as before
fightform.append(Form[fight])
fightset = instance.fightmma_set.all()
fightset_and_fightform = zip(fightset, fightform)
context{
"fightset_and_fightform":fightset_and_fightform, ### added to context
}
然后按照answer我可以通过模板传递它。
