Access Object Attributes using Symbols

Question

I have this helper that I am building:

def myhelper(object, attributes = [])
  attributes.each do |attr|
    object.attr
  end
end

I invoke this helper using:

myhelper Person, [:title, :name]

What I am trying to achieve is to print a list of attributes in Person dynamically but object.attr in myhelper method won't work.

How can I do that?

Answer 1

Try object.send(attr)

Also, do you want to do a map instead?

Answer 2

Is Person an ActiveRecord or ActiveModel object, or just an ordinary object?

Also, what do you mean by "won't work"? Are you getting no output, or are you getting an exception?
