How to select where ID in Array Rails ActiveRecord without exception

Question

When I have array of ids, like

ids = [2,3,5]

and I perform

Comment.find(ids)

everything works fine. But w

Answer 1

Now .find and .find_by_id methods are deprecated in rails 4. So instead we can use below:

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

It will work even if some of the ids don't exist. This works in the

user.comments.where(id: avoided_ids_array)

Also for excluding ID's

Comment.where.not(id: [2, 3, 5])
