You could add this somewhere, for instance in environment.rb:
class ActiveRecord::Base
def self.map_column(legacy, nice)
class_eval <<-EOS
def #{nice}
#{legacy}
end
def #{nice}=(val)
self.#{legacy} = val
end
EOS
end
end
The usage is
class Model < ActiveRecord::Base
map_column :_job, :job_id
map_column :_change, :change_id
...
end
You see the technique in case you prefer another kind of macro. BTW, that cannot be based on alias_method because AR accessors are not defined by then.
