With Rails 5.2:

 - message: 'Dangerous query method (method whose arguments are used as raw SQL) called
     with non-attribute argument(s): "CASE WHEN \"hostgroups\".\"title\" = ''928644347''
     THEN 1 ELSE 0 END". Non-attribute arguments will be disallowed in Rails 6.0. This
     method should not be called with user-provided values, such as request parameters
     or model attributes. Known-safe values can be passed by wrapping them in Arel.sql().'
   callstack: app/controllers/api/base_controller.rb:407:in `prioritize_friendly_name_records'

app/controllers/api/base_controller.rb:378 says: "#Should be replaced after moving to friendly_id version >= 5.0"

This should be re-done now in a Rails 5.2 friendlier way.
