Rails, ActiveRecord, query id in array of ints, keep order of passed array

Question

I am thinking about the best solution for a problem. Let\'s say that we have a list of ids of ActiveRecord model:

ids = [1, 100, 5, 30, 4, 2, 88, 44]
         


        

Answer 1

if you want to get a result of Model::ActiveRecord_Relation

order(Arel.sql("field(id, ids.join(', ') asc"))

Arel.sql is required to prevent the message in log:

Dangerous query method (method whose arguments are used as raw SQL) called with non-attribute argument(s)
