Create Rake task that will re-resize images based on changes to IMAGE_SIZES
Reported by Walter McGinnis | July 3rd, 2009 @ 10:25 AM | in 1.3
Create a rake task that will do the following:
- take uploaded original and resize bases on IMAGE_SIZES constant's hash of size specifications
- update the metadata for each ImageFile instance that matches a size specification accordingly (height, width, content_size, etc.)
- add new ImageFile instances if a new size specification has been added to IMAGES_SIZES
Possible improvements:
- be able to specify which size should be redone rather than doing all size specifications in IMAGE_SIZES
- be able to specify if ImageFile instances that are no longer associated with a IMAGE_SIZES spec should be destroyed, if so destroy them
Things to keep in mind:
- we don't want to break existing URLs for people if possible, I don't think this should be an issue, but keep that in mind
- you'll probably need to call AttachementFu's Rmagick processing directly to do the resizing

The rake task has been completed and tested on two sites. Both worked as expected.
The possible improvements aren't required at this point, so will be put on hold?
This work is available in the 1-3-prep-work branch (will be in master soon)
Documentation for the task is available at http://kete.net.nz/documentation/topics/show/255-how-can-i-change-t...
