Compare with:

all()

Returns an ActiveRecord::Relation scope object.

posts = Post.all
posts.size # Fires "select count(*) from  posts" and returns the count
posts.each {|p| puts p.name } # Fires "select * from posts" and loads post objects

fruits = Fruit.all
fruits = fruits.where(color: 'red') if options[:red_only]
fruits = fruits.limit(10) if limited?

You can define a scope that applies to all finders using default_scope.

                Class level methods will no longer inherit scoping from `#{scope._deprecated_scope_source}`
                in Rails 6.1. To continue using the scoped relation, pass it into the block directly.
                To instead access the full set of models, as Rails 6.1 will, use `#{name}.default_scoped`.
