我正在构建一个Django消息传递应用程序，其中每个聊天室都有自己的模板，模型和视图。我正在努力寻找一种方法，让用户使用用户输入来创建私人聊天室。我希望用户以模板形式指定详细信息，当他们单击提交时，将生成文件以创建聊天室。还是有更好的方法来做到这一点？任何建议将不胜感激。
哦，我将Django 2.1.2与Python 3.6.5结合使用。谢谢
编辑：我在下面添加一些代码
models.py：
class Chat(models.Model):
created = models.DateTimeField(auto_now_add=True)
#timeNow = models.DateTimeField()
user = models.ForeignKey(User, on_delete=models.CASCADE)
message = models.TextField()
file_upload = models.FileField()
class Meta:
verbose_name_plural = "general Chat"
def __unicode__(self):
return self.message
views.py：
def GeneralChat(request):
c = Chat.objects.all()
documents = Document.objects.all() #file upload
return render(request, "channels/generalChat.html", {'generalChat': 'active', 'chat': c, 'documents': documents})
def Post(request):
if request.method == "POST":
msg = request.POST.get('msgbox', None)
time = datetime.now()
c = Chat(user=request.user, message=msg, created=time)
c = Chat(user=request.user, message=msg)
if msg != '':
c.save()
return JsonResponse({ 'msg': msg, 'user': c.user.username})
else:
return HttpResponse('Request must be POST.')
def Uploads(request):
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return redirect('/generalChat')
else:
form = DocumentForm()
return render(request, 'channels/uploads.html', {
'form': form
