'；元组'；对象没有属性'；获取'；请求基于类的视图Django时

嗨，这应该是一个简单的我相信。我对基于类的观点失去了耐心。不太清楚他们是如何简化事情的。基于函数的视图看起来更具可读性，更有意义。无论如何，我正在尝试将我的一个函数视图转换为一个类视图，当我请求该视图时出现了这个错误

“tuple”对象没有属性“get”

PS我使用的是django 1.8.1，导入视图的方式是通过django.views.generic.View，而不是文档中描述的django.views.View。可能是相关的

这是url.py

from django.conf.urls import url
from . import views


urlpatterns = [
    url(r'^upload_photo/$', views.upload_photo, name='upload_photo'),
    url(r'^upload_photo_class/$', views.UploadPhotoView.as_view()),
    ]

这是基于类的视图

class UploadPhotoView(View):
    form = PhotoModelForm
    formset = formset_factory(PhotoExtendedModelForm, max_num=1, validate_min=True)
    template_name = 'upload_photo.html'

    @method_decorator(login_required)
    def dispatch(self, *args, **kwargs):
        return super().dispatch(*args, **kwargs)

    def get(self, request):
        form = self.form
        formset = self.formset
        return (request, self.template_name, {'form': form,
                                          'formset': formset})

    def post(self, request, *args, **kwargs):
        form = self.form(request.POST, request.FILES)
        formset = self.formset(request.POST)
        if all([form.is_valid(), formset.is_valid()]):

            photo = form.save()
            photo_instance = photo
            user_id = request.user

            for inline_form in formset:

                data = inline_form.save(commit=False)
                data.Photo = photo_instance
                data.user = user_id
                data.save()

            return render(request, 'upload_photo_done.html')

        else:
            return (request, self.template_name, {'form': form,
                                              'formset': formset})

@login_required
def upload_photo(request):
    form = PhotoModelForm
    formset = formset_factory(PhotoExtendedModelForm, max_num=1, validate_min=True)

    if request.method == 'POST':
         form = form(request.POST, request.FILES)
         formset = formset(request.POST)
         if all([form.is_valid(), formset.is_valid()]):

            photo = form.save()
            photo_instance = photo
            user_id = request.user

            for inline_form in formset:

                data = inline_form.save(commit=False)
                data.Photo = photo_instance
                data.user = user_id
                data.save()

            return render(request, 'upload_photo_done.html')

        else:
            return render(request, 'upload_photo.html', {'form': form, 'formset': formset})
    else:
        return render(request, 'upload_photo.html', {'form': form, 'formset': formset})

这是原始的基于函数的视图

class UploadPhotoView(View):
    form = PhotoModelForm
    formset = formset_factory(PhotoExtendedModelForm, max_num=1, validate_min=True)
    template_name = 'upload_photo.html'

    @method_decorator(login_required)
    def dispatch(self, *args, **kwargs):
        return super().dispatch(*args, **kwargs)

    def get(self, request):
        form = self.form
        formset = self.formset
        return (request, self.template_name, {'form': form,
                                          'formset': formset})

    def post(self, request, *args, **kwargs):
        form = self.form(request.POST, request.FILES)
        formset = self.formset(request.POST)
        if all([form.is_valid(), formset.is_valid()]):

            photo = form.save()
            photo_instance = photo
            user_id = request.user

            for inline_form in formset:

                data = inline_form.save(commit=False)
                data.Photo = photo_instance
                data.user = user_id
                data.save()

            return render(request, 'upload_photo_done.html')

        else:
            return (request, self.template_name, {'form': form,
                                              'formset': formset})

@login_required
def upload_photo(request):
    form = PhotoModelForm
    formset = formset_factory(PhotoExtendedModelForm, max_num=1, validate_min=True)

    if request.method == 'POST':
         form = form(request.POST, request.FILES)
         formset = formset(request.POST)
         if all([form.is_valid(), formset.is_valid()]):

            photo = form.save()
            photo_instance = photo
            user_id = request.user

            for inline_form in formset:

                data = inline_form.save(commit=False)
                data.Photo = photo_instance
                data.user = user_id
                data.save()

            return render(request, 'upload_photo_done.html')

        else:
            return render(request, 'upload_photo.html', {'form': form, 'formset': formset})
    else:
        return render(request, 'upload_photo.html', {'form': form, 'formset': formset})

在def get（）中，应该像这样返回一个HttpResponse对象

     HttpResponseRedirect('/success/')

或者使用render（）重定向到模板。您正试图返回一个带有呈现函数调用参数的普通元组。

类上传照片视图（FormView）：

它将简化许多表单处理和样板文件，这是基于类的视图的许多好处。像往常一样，这是伟大的

在您的情况下，它可能非常简单：

class UploadPhotoView(FormView):
    form_class = PhotoModelForm
    template_name = 'upload_photo.html'
    success_url = '/upload-done/' # set url to TemplateView.as_view(template_name="upload_photo_done.html")

 def form_valid(self, form):

你能发布完整的堆栈跟踪吗？你能发布完整的堆栈跟踪吗？嗨，谢谢你的工作！我也对post（）else:part做了同样的处理，并在那里放置了一个渲染。不客气。请接受这个答案，这样其他人在遇到类似情况时会有清晰的想法。嗨，谢谢你的帮助！我也对post（）else:part做了同样的处理，并在那里放置了一个渲染。不客气。请接受这一点作为答案，这样其他人在遇到类似情况时会有清晰的想法。您好，谢谢您的建议，我已尝试实施更改，但这样做会导致“请求”功能出现错误。据我所知，表格将获得帖子信息，它也会获得文件吗？为了确定用户id在FormView中的工作方式，我认为文件应该是

格式。已清理的\u数据['your\u upload\u name']

或

self.request.files['your\u upload\u name']]
