Question

我正在使用Django1.4.3和Pillow2.0.0开发一个应用程序。

我有一张上传图片文件的表单调整大小并裁剪发布的图像文件后，
我想保存图像文件，但发生错误。

在django的本地测试服务器中，错误不会发生并且运行良好，
但是在Heroku中，会发生错误。

你能告诉我一些建议吗？接收发布图像的代码如下。另外，我使用S3boto和django-storage。

def edit_photo(request):
    if request.user.is_authenticated():
        if request.method == 'POST':
            # save posted image as UserProfile.image temporarily
            posted_photo = request.FILES['posted_photo']
            file_content = ContentFile(posted_photo.read())
            profile = request.user.get_profile()
            temp_filename = "new_file_"+str(profile.id)+"_"+posted_photo.name
            profile.image.save(temp_filename, file_content)

            # read posted file
            data = profile.image.read()
            im = Image.open(StringIO.StringIO(data))

            # crop posted image
            cropping_box = (10, 10, 300, 300)
            photo = photo.crop(cropping_box)
            photo_comp = photo.resize((230, 230), Image.ANTIALIAS)

            # save the image
            thum = StringIO.StringIO()
            photo_comp.save(thum, "png")
            profile.image.save("saved_image_"+str(profile.id)+".png",ContentFile(thum.getvalue()))

            # delete temporary image
            default_storage.delete("faces/"+temp_filename)

            return redirect('../')

错误信息是这样的。

对于发现此问题的其他人......

当同时安装PIL和Pillow时可能会发生此TypeError（可能是由于隐藏的包要求而无意中）。您需要卸载两个 PIL和Pillow，然后重新安装所需的那个。

Heroku上的枕头不起作用
