gem 'httpcode'

$ gem install httpcode

  Example:
        HttpStatus.created.code  or HttpStatus.not_modified.code

  More Examples:
      status = HttpStatus.accepted
        => #<StatusCode:0x007fb85403e1c0 @code=202, @message="Accepted", @symbol=:accepted>
      status.code
        => 202
      status.to_i
        => 202
      status.message
        => "Accepted"
      status.code_and_message
        => [202, "Accepted"]

  If you know the number of the status code, but are not sure what function to call you can use from_code.
  Last Example:
      We know we want to use the 200 code, but not sure what function to call.

      status = HttpStatus.from_code 200
        => #<StatusCode:0x007fb85403e2b0 @code=200, @message="OK", @symbol=:ok>
      status.symbol
        => :ok

      Now we know that we can call HttpStatus.ok
