Rails: Overwriting default accessors

All columns of a model's database table are automagically available through accessors on the Active Record object.

When you need to specialize this behavior, you may overwrite the default accessors (using the same name as the attribute) and call read_attribute(attr_name) and write_attribute(attr_name, value) to actually change things. Example:

Copy
class Poet < ActiveRecord::Base def name=(name) write_attribute(:name, name.strip) end end
