Automatically add Scenario name to filename of screenshot in Selenium using Ruby

Question

I'm using Selenium, writing in Ruby. I've configured my env.rb file to save a screenshot of any failed tests that I run. The problem is it's hard to determine the scenario/step that failed as the filename is generic. I've managed to time stamp the filename using this:

After do |scenario|
    if scenario.failed?
       screenshot_file = "screenshot - #{Time.now.strftime('%Y-%m-%d %H-%M-%S')}.png"
       page.save_screenshot(screenshot_file)
     end
end

Is there a way in which I can get this filename to also pull the name of the scenario that failed so that it could be "scenario# date time.png"? I've seen a few examples online, none of which work.

Thank you

screenshot_file = "screenshot-#{scenario.name}-#{Time.now.strftime('%Y-%m-%d %H-%M-%S')}.png"
