Question

is there a way to do this

  def version=(version)
    self.revision = version
  end

  def version
    return self.revision
  end

with one line? I feel like it would be a pretty common thing to do. =\

Answer 1

When you say “model” do you mean ActiveRecord model?

In which case YES.

class MyClass < ActiveRecord::Base
  alias_attribute :version, :revision
end

will do what you want.

Else in plain Ruby

alias :version  :revision
alias :version= :revision=

Or

alias_method :version,  :revision
alias_method :version=, :revision=
