How to select where ID in Array Rails ActiveRecord without exception

The “find_all_by..” family of functions works without throwing exceptions.

Comment.find_all_by_id([2, 3, 5])

or

user.comments.find_all_by_id(potentially_nonexistent_ids)

Update: Rails 4

Comment.where(id: [2, 3, 5])

Update:Rails 4.x

current_user.comments.where(:id=>[123,"456","Michael Jackson"])

   A Relation object join more .where clauses, .limit clauses, etc.,It also allows non-existent IDs without throwing exceptions.

current_user.comments.where(id: [123, "456", "Michael Jackson"])

Alternative solution for Array Rails ActiveRecord : 

Model.joins(:another_model_table_name)
  .where('another_model_table_name.id IN (?)', your_id_array)
