How to query the active record for the following scenario

I have a model called StudioOrder where name and price are two attributes. Now I want to get price for a particular name. I am trying to do this .. like StudioOrder.find_by(name: "bla").price .. but it gives me no method error. What is the correct way to do it.

Thanks

I believe you can do something like this:

StudioOrder.where(:name => "bla").price

Using a rails app I have and the rails console, I used a similar syntax as yours (only using my model) so I am thinking it is another issue. Does your schema for StudioOrder have a name field?

2.2.1 :016 > Registration.find_by(first_name: "Aaron").last_name
  Registration Load (0.5ms)  SELECT  "registrations".* FROM "registrations"  WHERE "registrations"."first_name" = 'Aaron' LIMIT 1
 => "Kaye"

White spacing between brackets and find_by :(
