I'm using mongoid-4.0.0.beta1 and following their docs to define a scope I get this error:

Sample:
class Band
include Mongoid::Document
field :name, type: String
field :active, type: Boolean, default: true
default_scope where(active: true)
end
Actually, it seems that from version 4.0 onward we need to use lambda for scopes:
class Band
include Mongoid::Document
field :name, type: String
field :active, type: Boolean, default: true
default_scope -> { where(active: true) }
end
