Django def form_valid 有两种形式答案

【问题描述】：

我想在同一个视图中使用两种形式。这是一个受限渠道。第一种形式是聊天，第二种形式启动对话（布尔字段，默认值 = false）。所有表单共享相同的成功 url。

你有什么想法吗？我从 Django 开始 :) 感谢您的帮助

这是我的看法：

@method_decorator(login_required(login_url='/cooker/login'),name="dispatch")
class CheckoutDetail(generic.DetailView, FormMixin):
    model = Sugargroup
    context_object_name = 'sugargroup'
    template_name = 'checkout_detail.html'
    form_class = CreateSugarChatForm
    validation_form_class = LaunchSugargroupForm # that is what I would like to add (models: boolean field with false default = user activate channel in changing it by true thanks to the forms
    
    def get_context_data(self, **kwargs):
        context = super(CheckoutDetail, self).get_context_data(**kwargs)
        context['form'] = self.get_form()
        return context

    def form_valid(self, form):
        if form.is_valid():
            form.instance.sugargroup = self.object
            form.instance.user = self.request.user
            form.save()
            return super(CheckoutDetail, self).form_valid(form)
        else:
            return super(CheckoutDetail, self).form_invalid(form)
     
    ### I don't know how I can implement this into: def form_valid
    def form_valid(self, validation_form):
        validation_form.instance.user = self.request.user
        validation_form.save()
        return super(CheckoutDetail, self).form_valid(validation_form)
   ######        

    def post(self,*args,**kwargs):
        self.object = self.get_object()
        form = self.get_form()
        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_valid(form)

    def get_success_url(self):
        return reverse('checkout:checkout_detail',kwargs={"slug":self.object.slug})
    ...

【解决方案1】：

您可以通过添加一个名称来标识提交的表单的提交按钮。

所以你的标记看起来像;


<form action="" method="post">
    {{ form_1 }}
    <input type="submit" name="form_1" value="Submit" />
</form>

<form action="" method="post">
    {{ form_2 }}
    <input type="submit" name="form_2" value="Submit" />
</form>

然后就可以判断post方法中提交了哪个表单；


    def post(self, *args, **kwargs):
        
        if 'form_1' in request.POST:
            process_form_1()
        elif 'form_2' in request.POST:
            process_form_2()
