Question

我一直致力于扩展以下项目：jquery file upload form＆amp;我想只显示数据库中名为admin的列中值为1的项目。

有人可以告诉我如何修改以下基于类的视图，只显示符合上述要求的图像吗？

class PictureCreateView(CreateView):
    model = Picture

    def form_valid(self, form):
        self.object = form.save()
        f = self.request.FILES.get('file')
        data = [{'url': settings.MEDIA_URL + "pictures/" + f.name.replace(" ", "_"), 'thumbnail_url': settings.MEDIA_URL + "pictures/" + f.name.replace(" ", "_"), 'delete_url': reverse('upload-delete', args=[self.object.id]), 'delete_type': "DELETE"}]
        response = JSONResponse(data, {}, response_mimetype(self.request))
        response['Content-Disposition'] = 'inline; filename=files.json'
        return response

    def get_context_data(self, **kwargs):
        context = super(PictureCreateView, self).get_context_data(**kwargs)
        context['pictures'] = Picture.objects.all()
        return context

这看起来像是一个非常基本的Django问题，我建议你学习它是如何工作的。

class PictureCreateView(CreateView):
    model = Picture

    def form_valid(self, form):
        self.object = form.save()
        f = self.request.FILES.get('file')
        data = [{'url': settings.MEDIA_URL + "pictures/" + f.name.replace(" ", "_"), 'thumbnail_url': settings.MEDIA_URL + "pictures/" + f.name.replace(" ", "_"), 'delete_url': reverse('upload-delete', args=[self.object.id]), 'delete_type': "DELETE"}]
        response = JSONResponse(data, {}, response_mimetype(self.request))
        response['Content-Disposition'] = 'inline; filename=files.json'
        return response

    def get_context_data(self, **kwargs):
        context = super(PictureCreateView, self).get_context_data(**kwargs)
        # Change the all to some filter
        context['pictures'] = Picture.objects.filter(admin=1)
        return context

Django类视图 - 仅在“admin”列包含1时显示
