Rails update attributes not updating
And last but not least, any kind of discussion regarding Ruby on Rails documentation is very welcome on the rubyonrails-docs mailing list.
tkawa - I don't understand the status of this issue. Are we supposed to be able to use the above code to fix the issue of editable columns in tables?
Make sure to check Edge Guides first to verify if the issues are already fixed or not on the master branch.They are most useful when your active record models need to interact with external systems which are not part of the database transaction.Consider, for example, the previous example where the callbacks are called for all models created, updated, or destroyed within a transaction block.Callbacks are methods that get called at certain moments of an object's life cycle.With callbacks it is possible to write code that will run whenever an Active Record object is created, saved, updated, deleted, validated, or loaded from the database.
