Rails 4 Validations

So I'm watching the "Build a todo list in Rails 4" videos and I noticed that in order to validate length and presence of text/string in a form, Jason does this:

validates :title, presence: true
validates :title, length: { minimum: 3 }
validates :description, presence: true
validates :description, length: { minimum: 5 }

Instead of doing this:

validates :title, presence: true, length: { minimum: 3 }
validates :description, presence: true, length: { minimum: 5 }

I did it the 2nd way because it condenses it down to 2 lines of code as opposed to 4 lines of code. Is the first way good practice and should be followed or was it done like that just to make the example easier to see/understand?

Great question Steven. I wonder if he did it for readability. I have always done it the way you're doing it (all on one line).

I'm curious now though his reasoning - if it was because of best practices or personal preference.

Going further into other videos, I noticed he did a validation the same way I did. I still don't know which would be considered best practice, but either way at least I know he does it too :P
