Rails 4 default scope

Question

In my Rails app have a default scope that looks like this:

default_scope order: \'external_updated_at DESC\'

I have now upgraded to Rails 4

Answer 1

You can also use the lambda keyword. This is useful for multiline blocks.

default_scope lambda {
  order(external_updated_at: :desc)
}

which is equivalent to

default_scope -> { order(external_updated_at: :desc) }

and

default_scope { order(external_updated_at: :desc) }

Answer 2

This is what worked for me:

default_scope  { order(:created_at => :desc) }
