ActiveRecord: Limiting columns selected by default

limiting-columns-selected.rb

class SomeModel < ::ActiveRecord::Base
   default_scope -> { select('id') } }
end

# only select id
SomeModel.where(name: 'Wibble').all

# override and select all columns
SomeModel.unscoped.where(name: 'Wibble').all

# override select for specific columns
SomeModel.select('id, column1, column2, name').where(name: 'Wibble').all

# One thing not represented is adding to the default selected columns.
# Right now, when overriding select you have to supply all of the columns you want.
