Django：将字段添加到 CreateVView.form_valid 中的 ModelForm

我有用户在我的网站中创建列表，我使用通用 CreateView 来允许他们创建列表。列表的字段之一是所有者（创建列表的人）。

要求用户选择所有者是没有意义的，因为创建它的用户已经是所有者。

因此，我向 CreateView 传递一个“form_class”而不是“model”参数，其中 form_class 不包括所有者字段。

为了保存表单，我需要将所有者添加到其中。

我对 CreateView 进行了子类化并添加了 form_valid 方法，但我在执行此操作时遇到了问题。

到目前为止，我明白

class MyCreateView(CreateView)
    form_class = ListForm

def form_valid(self, form):
    form.??? = self.request.user -->> expression of the left side
    return super(MyCreateView, self).form_valid(form)

它应该是简单的事情。在此帖子中，他们建议使用 self. object.owner，但 self.object 是 None 类型。

我应该如何处理这个问题？谢谢

原文

I have users creating lists in my site and I'm using the generic CreateView to allow them create them. One of the fields of a list is the owner (who creates it).

It does not make sense to ask users to select the owner, since the user that is creating it is already the owner.

So, I'm passing to the CreateView a "form_class" instead of a "model" parameter where the form_class excludes the owner field.

In order to save the form, I need to add the owner to it.

I subclassed CreateView and added a form_valid method, but I'm having problems doing this.

So far, I got

class MyCreateView(CreateView)
    form_class = ListForm

def form_valid(self, form):
    form.??? = self.request.user -->> expression of the left side
    return super(MyCreateView, self).form_valid(form)

It should be something simple. In this thread, they say to use self.object.owner, but self.object is a None type.

How should I handle this?
Thanks
