I was a little surprised to discover that when you update an association through nested attributes, it won't touch the parent record. It makes sense when you consider that Rails is optimizing by not writing records that have not changed, but if were using updated_at on the model for caching you may be surprised.
For instance:
Showing posts with label nested attributes. Show all posts
Showing posts with label nested attributes. Show all posts
