unscoped() public

Returns a scope for this class without taking into account the default_scope.

class Post < ActiveRecord::Base
  default_scope :published => true
end

Post.all          # Fires "SELECT * FROM posts WHERE published = true"
Post.unscoped.all # Fires "SELECT * FROM posts"

This method also accepts a block meaning that all queries inside the block will not use the default_scope:

Post.unscoped {
  limit(10) # Fires "SELECT * FROM posts LIMIT 10"
}

It is recommended to use block form of unscoped because chaining unscoped with named_scope does not work. Assuming that published is a named_scope following two statements are same.

Post.unscoped.published Post.published

unscoped.all / unscoped.count

At least in console, doing unscoped.all or unscoped.count initially returns expected results but, after you’ve added new records outside of the default_scope those two calls seem to use some cached values.

Therefore it should always be used with the block (as they sort of imply in the doc). unscoped { all } and unscoped {count }
