I have a variable called column with the value of "bla" (column "bla") I have a model call Location where method bla is defined (amongst many other methods). What I would like to to is to call the method in Location defined in the variable column. I tried: Location.column.constantize but that gave me an error NoMethod. I am sure there is a very simple way in Ruby as always :-) who can help me? thanks --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Like so: column = "bla" my_location = Location.find(1) my_location.send(column) # calls mylocation.bla [1] http://www.ruby-doc.org/core/classes/Object.html#M000334 --- Ryan Carmelo Briones -- View this message in context: http://www.nabble.com/activerecord-model-constantize-question-tf4162558.html#a11843879 Sent from the RubyOnRails Users mailing list archive at Nabble.com. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
