Add a method to array object

Question

I've found this post:

Array#add_condition But i didn't understand to how implement it in my rails project

How can i do it?

Answer 1

Copy and paste that code into a file. There — the method is added to Array. The lib directory would be a good place for it.

Answer 2

Just create add_condition.rb file, paste code snippet from your link and save it in lib directory in your Rails app.
