How to perform preload on top of a preload in rails?

I have these model associations:

class User < ApplicationRecord
   has_many taken_tests
.
.
.
end

class Test < ApplicationRecord
   has_many questions
.
.
end

Now User.preload(:taken_tests) preloads the tests. Is there a way I can preload questions also along with the tests? Something like: User.preload(:taken_tests).preload(:questions) ?

Yes, you can preload the chain of associations

User.preload(taken_tests: :questions)

This will load all the user's tests along with all the questions which belongs to those tests

You can chain the associations if you need if you have answers you can preload them too.

User.preload(taken_tests: [questions: :answers])
