Python '；OneToOneField'；对象没有属性'；获取'；在基于函数的视图中

我正在编写一个由两部分组成的表单，其中我希望将第一部分中保存的对象作为第二部分中对象的OneToOneField传递

在views.py中：

def object_entry(request):
    if request.method == 'POST':
        title_form = TitleEntry(request.POST)
        object_form = ObjectEntry(request.POST)
        if title_form.is_valid():
            title = title_form.cleaned_data['title']
            title_type = title_form.cleaned_data['title_type']
            title_lang = title_form.cleaned_data['lang']
            title_translation = title_form.cleaned_data['translation']
            title_currency = title_form.cleaned_data['currency']
            title_level = title_form.cleaned_data['level']
            title_note = title_form.cleaned_data['note']
            title_source = title_form.cleaned_data['source']
            new_title = title_form.save()
            return new_title

        else:
            return render_to_response('objectinfo/objectregister_form.html', {'object_form': object_form, 'title_form': title_form})

        if object_form.is_valid():
            object_form.preferred_title = new_title
            snapshot = object_form.cleaned_data['snapshot']
            work_type = object_form.cleaned_data['work_type']
            source = object_form.cleaned_data['source']
            brief_description = object_form.cleaned_data['brief_description']
            description_source = object_form.cleaned_data['description_source']
            comments = object_form.cleaned_data['comments']
            distinguishing_features = object_form.cleaned_data['distinguishing_features']
            new_object = object_form.save()
            reorg.AccessionNumber.generate(new_object.pk)

            return HttpResponseRedirect('/work/')
            # return HttpResponseRedirect(reverse(description_edit, args=(new_object.pk,)))

        else:
            return render_to_response('objectinfo/objectregister_form.html', {'object_form': object_form, 'title_form': title_form})

    else:
        title_form = TitleEntry()
        object_form = ObjectEntry()
        return render(request, 'objectinfo/objectregister_form.html', {'object_form': object_form, 'title_form': title_form})

在forms.py中：

class ObjectEntry(ModelForm):
    class Meta:
        model = ObjectRegister
        fields = ['snapshot', 'work_type', 'source', 'brief_description', 'description_source', 'comments', 'distinguishing_features', 'storage_unit', 'normal_unit']

 class TitleEntry(ModelForm):
    class Meta:
        model = ObjectName
        fields = ['title', 'title_type', 'lang', 'translation', 'currency', 'level', 'note', 'source']

提交表单时，返回错误

“ObjectName”对象没有属性“get”

将

new\u title

传递为

object\u表单的OneToOneField的正确方法是什么？首选\u title

？

如果表单有效，视图将返回新实例。这是不正确的，您应该始终返回HTTP响应

    if title_form.is_valid():
        ...
        return new_title

最好在处理有效表单后重定向，以防止重复提交表单。

请显示完整的回溯。is\U valid子句中的所有变量赋值似乎都没有意义。@Alasdair:谢谢，请参阅编辑的问题您正在使用的是

render

和

render\u to\u response

的混合。您应该在任何地方使用

render

-

render\u to\u response

已过时。另外，请注意，如果对象形式为.is\u valid（）：，您的视图将永远无法访问

，因为
if title\u form.is\u valid（）：
的两个分支都有返回语句。您的意思是说同一个模板上不能有两个形式吗，也就是说，我应该首先有一个带有标题表单的页面，然后在该表单保存后，为目标表单显示一个单独的页面？在同一模板上可以有两个表单。当您返回响应时，最好重定向，以防止重复提交。谢谢。我仍然不知道如何使这两个表单在同一个模板上工作，所以我将它们拆分为两个单独的视图，并将第一个表单的id作为kwarg传递给第二个表单。
