ActiveRecord scopes must be loaded before using RSpec's "=~" matcher

To test whether two arrays have the same elements regardless of order, you can use the =~ matcher in RSpec < 2.11:

Copy
actual_array.should =~ expected_array

If either side is an ActiveRecord scope rather than an array, you should call to_a on it first, since =~ does not play nice with scopes:

Copy
actual_scope.to_a.should =~ expected_scope.to_a

If you use RSpec >= 2.11 we recommend to use the match_array or eq matcher. There are also use cases where the contain_exactly matcher fits better.

Does your version of Ruby on Rails still receive security updates?
Rails LTS provides security patches for old versions of Ruby on Rails (3.2 and 2.3).
