使用PIL for Django网站旋转通过电子邮件上传的图像

My website allows users to upload photos to their gallery via email and it works perfectly. However, photos taken on the iPhone in portrait mode do NOT rotate correctly. I would like to rotate the photo using PIL during the "mail filtering" process. Here is the code that I am using to successfully retrieve the image from the email and save to my Django model

我的网站允许用户通过电子邮件将照片上传到他们的画廊,它完美无缺。但是,在纵向模式下在iPhone上拍摄的照片无法正确旋转。我想在“邮件过滤”过程中使用PIL旋转照片。这是我用来成功从电子邮件中检索图像并保存到我的Django模型的代码

    image = ContentFile(b64decode(part.get_payload()))
    img = Photo(user=user)
    filename = part.get_filename().lower()
    img.img.save(filename, image)
    img.save()

*Updated code that successfully rotates temp image to local dir *

*更新了成功将临时图像旋转到本地目录的代码*

     image = ContentFile(b64decode(part.get_payload()))
     im = Image.open(image)
     tempfile = im.rotate(90)
     tempfile.save("/srv/www/mysite.com/public_html/media/images/rotate.jpg", "JPEG")
     img = Photo(user=user)
     img.img.save('rotate.jpg', tempfile)
     img.save()

Now, I'm trying to take the "temp image" and save it to my model. Unfortunately, it is not saving. Any suggestions would be greatly appreciated.

现在,我正在尝试拍摄“临时图像”并将其保存到我的模型中。不幸的是,它不是在储蓄。任何建议将不胜感激。

clearly states that rotate() returns an new image instance.

清楚地说明rotate()返回一个新的图像实例。

There is nothing in the documentation about in-place operations. Or?

文档中没有关于就地操作的任何内容。要么?
