Pagination with nested resource

[luvcjssy]

I have an issue with nested resource. Here is example:

p = Products.first
p.steps.count ---> 10
a = p.steps.paginate(page: 1, per_page: 2)
a.count ---> 10

but,

a = p.steps.paginate(page: 1, per_page: 2).to_a
a.count ---> 2

So, which case is correct?

I have the same issue.

Depends what you want to be counting.

The p.steps.paginate(page: 1, per_page: 2).count call will call the count method on the underlying ActiveRecord::AssociationRelation

The p.steps.paginate(page: 1, per_page: 2).to_a.count call will execute the paginate method when the to_a method is called, and then the count method on the Array.

As for 'correctness'... it states in the README:
# paginate in Active Record now returns a Relation

But paginate must be changing the to_a result.
