Building a validation that checks :city presence and its length

Hey All!

First post here on Treehouse. I'm having issues getting my code to pass for this test... I'm sure it's something small but I just can't seem to figure it out. Can anyone spot any issues with this?

TREEHOUSE QUESTION: Build a validation that checks a field called :city to ensure that it’s between 2 and 30 characters long, and is present.

MY RESPONSE: 

class Contact < ActiveRecord::Base
   validates :city, presence: true, length: {in 2..30}
 end

Hey Jesse! Looks like the issue is with the in keyword. As you have it, it's not a valid Ruby hash.

class Contact < ActiveRecord::Base
   validates :city, presence: true, length: {in: 2..30}
end

Hope this helps!
