Begin, Rescue with API endpoint

Question

Here is my method:

def get_video_duration
  @time ||= Panda.get("/videos/#{@video.panda_id}/metadata.json")["duration"]
  format_duration
end

I need to write this method "better" in wrapping it with a begin, rescue block so that @time could be nil depending on the response from the API.

Answer 1

Yes, possible using inline rescue clause.

def get_video_duration
    @time ||= Panda.get("/videos/#{@video.panda_id}/metadata.json")["duration"] rescue nil
    format_duration
end

Or better explicitly do it.

def get_video_duration
  @time ||= Panda.get("/videos/#{@video.panda_id}/metadata.json")["duration"]
rescue YourException
  @time = nil
  format_duration
end
