form_valid django-extra-views 中的方法。在现实形式（S）_有效

Question

我正在尝试使用 Django Extra Views 包创建基于模型 + 内联表单集 + 来自 USER 模型的额外信息的新条目。我知道如何通过基于函数的视图来做到这一点，但现在试图减少代码量：

我有2个模型+用户模型：


Model1: # primary model 
author = models.ForeignKey("ExtraUser", )
+some fileds

Model2 # secondary model
photo = models.ForeignKey("Model1", )
+ some fields

# user model
Model ExtraUser(AbstractBaseUser)
+ some fileds

我使用以下 VIEW 一起渲染和保存它们：


class ItemInline(InlineFormSetFactory):
    model = Model2
    fields = ["somefiled"]


class CreateBoatView(SuccessMessageMixin, LoginRequiredMixin, CreateWithInlinesView):
    model = Model1
    inlines = [ItemInline]
    fields = ["list of the fields here"]
    template_name = 'create.html'

    def get_success_url(self):
        return reverse('app:url', args=(self.object.pk, ))

除一件事外一切正常：我无法将当前用户指定为条目作者，即作者 = models.ForeignKey("ExtraUser", ) 始终为 NULL

在基于祖先函数的视图中，我曾经执行以下操作：

if form1.is_valid():
    prim = form1.save(commit=False)
    prim.author = request.user  # that is I connect this entry to the current user.
   # + do something + save(commit=True) finally.

如何在 CreateWithInlinesView 中做同样的事情？

尝试关注。努力工作

    def dispatch(self, request, *args, **kwargs):
        self.user = request.user
        return CreateWithInlinesView.dispatch(self, request, *args, **kwargs)

    def form_valid(self, form): #(self, form, inlines)??
        self.object = form.save(commit=False)
        self.object.author = self.request.user
        self.object.save()
        return HttpResponseRedirect(self.get_success_url())


# super-class form_valid method (for reference)

    def forms_valid(self, form, inlines):
        """
        If the form and formsets are valid, save the associated models.
        """
        self.object = form.save()
        for formset in inlines:
            formset.save()
        return HttpResponseRedirect(self.get_success_url())

好吧，非常感谢 Django Extra Views 的作者，因为他们添加了特殊方法而不是 form_valid... 猜猜它叫什么？？？ forms_valid。您确实需要几秒钟才能有所不同，对吗？我花了大约 5 个小时才找到它。

最后：

    def forms_valid(self, form, inlines): #yes, f%%ng form(s)_valid, yeh...
        """
        If the form and formsets are valid, save the associated models.
        """
        self.object = form.save(commit=False)
        self.object.author = self.request.user
        form.save(commit=True)
        for formset in inlines:
            formset.save()
        return HttpResponseRedirect(self.get_success_url())
