===>>GO TO THE STORE<<=== п»їModule: ActiveRecord::Store.
Store gives you a thin wrapper around serialize for the purpose of storing hashes in a single column. It’s like a simple key/value store baked into your record when you don’t care about being able to query that store outside the context of a single record.
You can then declare accessors to this store that are then accessible just like any other attribute of the model. This is very helpful for easily exposing store keys to a form or elsewhere that’s already built around just accessing attributes on the model.
Make sure that you declare the database column used for the serialized store as a text, so there’s plenty of room.
You can set custom coder to encode/decode your serialized attributes to/from different formats. JSON, YAML, Marshal are supported out of the box. Generally it can be any wrapper that provides load and dump .
NOTE - If you are using PostgreSQL specific columns like hstore or json there is no need for the serialization provided by store . Simply use store_accessor instead to generate the accessor methods. Be aware that these columns use a string keyed hash and do not allow access using a symbol.
class User ActiveRecord :: Base store :settings , accessors: [ :color , :homepage ] , coder: JSON end u = User . new ( color: ' black ' , homepage: ' 37signals.com ' ) u . color # Accessor stored attribute u . settings [ :country ] = ' Denmark ' # Any attribute, even if not specified with an accessor # There is no difference between strings and symbols for accessing custom attributes u . settings [ :country ] # => 'Denmark' u . settings [ ' country ' ] # => 'Denmark' # Add additional accessors to an existing store through store_accessor class SuperUser User store_accessor :settings , :privileges , :servants end.
The stored attribute names can be retrieved using stored_attributes .
User . stored_attributes [ :settings ] # [:color, :homepage]
Overwriting default accessors.
All stored values are automatically available through accessors on the Active Record object, but sometimes you want to specialize this behavior. This can be done by overwriting the default accessors (using the same name as the attribute) and calling super to actually change things.
class Song ActiveRecord :: Base # Uses a stored integer to hold the volume adjustment of the song store :settings , accessors: [ :volume_adjustment ] def ( decibels ) super ( decibels . to_i ) end def volume_adjustment super . to_i end end.
