Hello zope,
i want to store images, and call them by id. it needs to be used from other places, so it will go in a mysql table, base64 encoded.
how to write a function, that gets the image by id, and returns it to the browser with the correct content type?
i should use a python script for that? or can it be made in dtml or pt?
how to make it respond to this?
http://zopehost/images/image_id.jpg
or something similar? ... with 'images' being the script....
From a python script, you can use the 'traverse_subpath' binding to get hold of those elements of the url after that of the script itself. I believe the elements are returned as a list or tuple, so you access them like
traverse_subpath[0] which in your example, would give you 'image_id.jpg'. You could then pass this as an argument to a zsql method in order to return the correct image. However, if you are getting several images, this could get expensive as several database queries would be performed. Perhaps you'd be better storing the images on the filesystem and using something of the LocalFS ilk to access them from zope. Being on the filesystem, you could of course make them accessible to to the other applications that you speak of. Just an idea tim
