Pagination

[zaratan]

Why?

Let's say you have 50.000 lessons. One personne visit the /lessons url, do we really want to return MULTIPLE mo of data ? Our request might even timeout. So let's paginate results.

Must have

• Every index routes should return its result pagined.
• Use Kaminari
• Your app should accept a page[number] and a page[size] to chose which results to return
• Of course your results must be ordered by created_at by default
• Page size must have a maximum
• You must return a meta about the number of pages, the current page number, the total quantity of results and other easy metrics. CF: https://github.com/rails-api/active_model_serializers/blob/0-10-stable/docs/howto/add_pagination_links.md#json-adapter
