Overriding third-party method in Ruby

Question

I'm developing some tool using pure ruby and RestClient and I'd like to override default log_request method of Request class.

lib/restclient/request.rb

module RestClient
  class Request
    def log_request
      RestClient.log << "SECRET"
    end
  end
end

But now, if I try to test this, it is not working:

$ irb
irb(main):001:0> require 'restclient'
=> true
irb(main):002:0> RestClient.log = "stdout"
=> "stdout"
irb(main):003:0> RestClient.get("http://localhost")
RestClient.get "http://localhost", "Accept"=>"*/*; q=0.5, application/xml", "Accept-Encoding"=>"gzip, deflate"

Expected to see only SECRET as output.

I'm probably missing, how to "inject" my code in default RestClient library ?

How can I do this from another file in lib/mytool/somefile.rb ?

Answer 1

This file need to be exactly required after require 'restclient' Adding load 'lib/restclient/request.rb' did the trick

Answer 2

Since you place it in your lib folder, this file is never being loaded as RestClient::Request constant is already defined. Place this code inside your config/initializers folder
