Rails query, I want to part of my query to be a variable

I have this method below.

The problem is that I want to pass in twitter_type as a parameter which changes depending on the calling code. The code below works but the method "followers" is hard coded. I want that to be the variable twitter_type. I have tried various ways but get it to work.

def get_change_channel(channel_id, twitter_type)
  base_value = Count.where(created_at: Date.yesterday.beginning_of_day..Date.yesterday.end_of_day)
                  .where(channel_id: channel_id).first.followers
get_current_channel_followers(channel_id) - base_value

end

Thanks for any guidance.

Simon

You can use #public_send:

 def get_change_channel(channel_id, twitter_type)
   base_value = Count.where(created_at: Date.yesterday.beginning_of_day..Date.yesterday.end_of_day)
              .where(channel_id: channel_id).first.public_send(twitter_type)
