Rails 4: find all records

Question

Now that ActiveRecord::Relation#all is deprecated in Rails 4, how are you supposed to iterate all records?

Used to be like:

Foo.all.each do |foo|
  # w         


        

Answer 1

Release notes for Rails 4:

Model.all now returns an ActiveRecord::Relation, rather than an array of records. Use Relation#to_a if you really want an array.

So your code will look like this:

Foo.all.to_a.each do |foo|
  # whatever
end
