Rails Serialize a column

I never used serialize before since Postgres supports :json and :jsonb columns which are better. It’s still useful that I can still store Hash data in the sqlite db text column— especially if my students, who aren’t using Postgres, want to do complicated stuff like OAuth and need to store some credentials.

Re: Spotify API

# in the action of the callback URL...
spotify_user = RSpotify::User.new(request.env['omniauth.auth'])
user = User.find_or_create_by({ :spotify_info => spotify_user.to_hash })

#  spotify_info :text
#
class User < ApplicationRecord
  serialize(:spotify_info)
end
