Edit Question
Title
Body
In general, how can I get a reference to an object whose name I have in a string? More specifically, I have a list of the parameter names (the member variables - built dynamically so I can't refer to them directly). Each parameter is an object that also has an from_s method. I want to do something like the following (which of course doesn't work...): define_method(:from_s) do | arg | @ordered_parameter_names.each do | param | instance_eval "field_ref = @#{param}" field_ref.from_s(param) end end
