reload(options = nil) public Reloads the attributes of this object from the database. The optional options argument is passed to find when reloading so you may do e.g. record.reload(:lock => true) to reload the same record with an exclusive row lock.

4 thanks reload equivalent for models
The reset_column_information method provides a similar function for the model itself. Most useful during migrations.
0 thanks reload is deprecated? what's the new alternative?
What’s the recommended alternative to reload for more recent versions of Rails?
0 thanks Moved to ActiveRecord::Persistence
This isn’t deprecated, it was just moved in Rails 3. See:
