How to use a model method within a scope?

I have a method: 

def can_book_appointment?

and i want to use it in a scope for the activeadmin gem 

scope :cannot_book_appointment, lambda { |self| , {:condition => !self.can_book_appointment?}

I did try

scope :place_cannot_book, lambda { PlaceDetail.all.reject{|n| !n.can_book_appointment?} }

but i get a error in activeadmin:

undefined method 'reorder' for #< Array:0x121bf5e8>

I know this doesn't work, but it helps to get an idea of my intention. How can I use this method on each records of the model?

You can't do that. Scopes are applied at the database-level, your can_book_appointment? method exists at the model level. They can't interact the way you're trying to make them interact.

You need to define a second scope that applies the same check that can_book_appointment? performs, but at the database level.
