Question

Ruby 1.9

I’m trying to do a trivial operation in Ruby. I want to change each element of array by adding some data to its property title as a prefix.

def my_proc
         @data = SomeTable.all
         @data.each { |d| 'my_title___'<< pt.title }
end

What did I do wrong?

UPDATE: I need to append some value to pt.title as a prefix. If pt.title == “some title” then after appending it must be “my_title___some title”. Of course, as a result it must be an array of objects with changed titles.

How do I do that?

Answer 1

Do you mean this?

@data.each { |d|  d.title = 'my_title___' + d.title }
