python - Django get_initial 基于类的 View 方法不起作用

Question

我尝试在 FormView 中使用 get_initial 来预填充“主题”字段以获取“批发商感兴趣”文本，但它不起作用。如果重要的话，我正在使用 Django 1.5、Python 2.7。这是我的代码。我是不是漏掉了一步？

class ContactView(FormView):
    """
    ContactForm is a ModelForm
    """
    template_name = 'core/contact-us.html'
    form_class = ContactForm
    success_url = reverse_lazy('products:index')
    initial = {'subject': 'I am interested in making a wholesale purchase'}


    def get_initial(self):
        """
        Returns the initial data to use for forms on this view.
        """
        return self.initial

    def get_form_kwargs(self):
        kwargs = {'initial': self.get_initial()}
        return kwargs

    def form_valid(self, form):
        cd = form.cleaned_data
        contact = Contact.objects.create(**form.cleaned_data)
        if contact:
            print 'contact created'
        else:
            print 'not created'
        if contact is not None:
            # send contact email
            msg = contact_email(name=cd['name'], email=cd['email'], subject=cd['subject'], message=cd['message'])
            msg.send()
            # Add success message 
            msg = 'Your contact email has been successfully sent.  We look forward to speaking with you.'
            messages.info(self.request, msg)
        return super(ContactView, self).form_valid(form)

编辑

我删除了 get_initial 和 get_form_kwargs 但仍然没有运气。如果有帮助的话，这是我的Form的粘贴。我是否需要附加我想要以某种方式放入表单中的内容的首字母？感谢您的帮助!

class ContactForm(forms.ModelForm):

    class Meta:
        model = Contact  
        fields = ('name', 'email', 'subject', 'message',)
        widgets = {
            'message': forms.Textarea(attrs={'cols': 20, 'rows': 20}),
        }

不要使用FormView，而是尝试CreateView。它是 FormView 的子类，负责处理您的实际模型。

另外，如何在模板中显示表单？如果您手动浏览所有字段，您可能不会显示初始值。
