在Django中显示来自数据库的图像？

Question

I have a read only db that I don't have the ability to change. I know that it is extremely inefficient to store images in a database. However I don't have control over this one. I need to display the image from the field in the database. How can you do this in Django?

Answer 1

1. Retrieve the image from the database as a binary,
2. write that directly into the http response content (with StringIO?),
3. set the relevant image mimetype/header

Don't forget to set the content length in the response. Experiement with 'streaming' if the images are huge.
