Disguise your model ID's when displayed in the UI or API

Add this line to your application's Gemfile:

gem 'super_id'

And then execute:

$ bundle

Or install it yourself as:

$ gem install super_id

In your model, you can use super id for the primary key

# app/models/flock.rb

class Flock < ActiveRecord::Base
  has_many :seagulls

  use_super_id_for :id
end

You can use super id for foreign keys too:

# app/models/seagull.rb

class Seagull < ActiveRecord::Base
  belongs_to :flock

  use_super_id_for [:id, :flock_id]
end

SuperId potentially supports multiple encoding algorithms, but currently is limited to short uid.

Optional Default: :short_id

# app/models/flock.rb
class Flock < ActiveRecord::Base
  has_many :seagulls

  use_super_id_for :id, as: :short_uid
end

Each encoding algorithm may have options of its own, which can be added to the use_super_id_for arguments.

Options and defaults

• salt: ''
• min_hash_length: 0
• alphabet: 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890'

For example, you can use a different salt for each model, and it will encode equal id's differently:

# app/models/flock.rb
class Flock < ActiveRecord::Base
  has_many :seagulls

  use_super_id_for :id, as: :short_uid, salt: 'foo'
end

# app/models/seagull.rb
class Seagull < ActiveRecord::Base
  belongs_to :flock

  use_super_id_for [:id, :flock_id], as: :short_uid, salt: 'bar'
end
