Python 如何在关系模型中插入与第一个模型（父模型）数据库实体相关的记录

在这里，我有两个独立的模型“用户”模型和“事件”模型。事件模型与用户模式相关。现在我想做的是，当一个用户填写事件表单并提交时，那么应该只针对该用户创建事件记录

views.py

class EventCreationForm(View):
    template_eventcreationform = 'eventcreationform.html'
    form_class = EventForm

    def get(self, request):
        form = self.form_class(None)
        return render(request, self.template_eventcreationform, {'form': form})

    def post(self, request):
        # data is here
        form = self.form_class(request.POST)
        if form.is_valid():
            event = form.save(commit=False)
            user = User.objects.get(
                #######################################################
                #####            currently logged user            #####
                ###   what should i put here to get current user?   ###
                #######################################################
            )
            form.user = user.email
            event_name = form.cleaned_data.get('event_name')
            event_date_time = form.cleaned_data.get('event_date_time')
            event_address = form.cleaned_data.get('address')
            event.save()
            message = 'Event added'
            return render(request, 'base.html', {'message': message})
        else:
            message = 'Invalid form data, try again'
            form = self.form_class(None)
            return render(request, self.template_eventcreationform, {'message': message, 'form': form})

首先，您可能希望使用，以便只有登录的用户才能访问该视图

from django.contrib.auth.mixins import LoginRequiredMixin

class EventCreationForm(LoginRequiredMixin, View):

您可以使用

self.request.user

访问登录的用户

    if form.is_valid():
        event = form.save(commit=False)
        event.user = self.request.user
        event.save()
        message = 'Event added'
        return redirect('/success-url/')

请注意，最好在保存事件后重定向，以防止重复提交表单

请注意，您正在复制或的许多功能。如果您使用这些，就不必编写那么多代码

class EventCreationForm(LoginRequiredMixin, CreateView):
    template_name = 'eventcreationform.html'
    form_class = EventForm
    success_url = '/success-url/'  # form_valid() will redirect here

    def form_valid(self, form):
        form.instance.user = self.request.user
        return super(EventCreationForm, self).form_valid(form)

我对jango是新来的，所以如果我先弄清楚基本知识，然后再使用速记会更好。
