我有一个名为 Message 的模型，它有一个名为 in_response_to 的字段。我使用此字段通过将原始消息的主键存储在每个相关消息中来识别哪些消息彼此相关，并列出所有消息
如果我收到您的新消息并且我想回复。我会在我的文本框下创建一个 hidden_field 并存储新的消息主 ID，并通过将主键存储在 in_response_to 中来使用它来创建消息，这样我就知道该消息与该消息相关并且该方法会重复，因此每条相关消息都会有原始主键。
所以它就像
(1) = message primary key
(s) = store message primary key inside in_response_to
John(1) send mail to Peter(s)
Peter(1) send mail to John(s)
John(1) send mail to Peter(s)
现在的问题是，如果我给你发消息。in_response_to 是空白的，因为它是一条新消息。如果您回复了该消息，您会将我的主键存储在 in_response_to 但当我再次尝试回复时。我最终将它发送给自己。我不知道为什么。有人可以帮帮我吗 。我在兜圈子
问题就在这里
if messages.in_response_to:
if messages.user != request.user:
primary = messages.in_response_to
Message.objects.create(user=request.user,recipient=messages.user,body=body,in_response_to=primary)
return HttpResponseRedirect(reverse('world:message'))
if messages.user == request.user:
Message.objects.create(user=request.user,recipient=messages.recipient.user,body=body,in_response_to=primary)
Message.objects.create(user=request.user,recipient=messages.user,body=body,in_response_to=messages)
return HttpResponseRedirect(reverse('world:message'))
