Ruby, Array, Object - Select Object

Question

#!/usr/local/bin/ruby
class OReport
   attr_accessor :id, :name
   def initialize(id, name, desc)
      @id       = id
      @name     = name
      @desc     = desc
   end
end

reports = Array.new
reports << OReport.new(1, 'One', 'One Desc')
reports << OReport.new(2, 'Two', 'Two Desc')
reports << OReport.new(3, 'Three', 'Three Desc')

How do I now search "Reports" for 2, so that I can extract name and description from it?

Answer 1

Use find to get an object from a collection given a condition:

reports.find { |report| report.id == 2 }
#=> => #<OReport:0x007fa32c9e85c8 @desc="Two Desc", @id=2, @name="Two">

If you expect more than one object to meet the condition, and want all of them instead of the first matching one, use select.
