django - 发布数据后，是否可以通过基于类的 View 在 django 中创建 session ？

Question

class CreateCompanyView(CreateView):
    model = Company
    template_name = 'create/company_create.html'
    form_class = CompanyForm
    success_url = '/'

    def post(self, request, *args, **kwargs):
        form = self.form_class(request.POST)
        if form.is_valid():
            instance = form.save(commit=False)
            #section where the session is supposed to be created
            request.session['company'] =instance.pk
            instance.save()
        return redirect("/")

如果有人基于使用基于类的 View 有更简单的方法或其他替代方法，我将不胜感激

处理表单的基于类的 View 有一个方法 form_valid这是在表单有效的情况下运行的。由于您想为特定情况编写一些额外的代码，您应该覆盖该方法而不是 post :

class CreateCompanyView(CreateView):
    model = Company
    template_name = 'create/company_create.html'
    form_class = CompanyForm
    success_url = '/'
    
    def form_valid(self, form):
        response = super().form_valid(form)
        self.request.session['company'] = self.object.pk # `form_valid` saves the object to the variable `self.object`
        return response
