How to add pagination links

If you want pagination links in your response, specify it in the render

  render json: @posts, pagination: true

AMS relies on either Kaminari or WillPaginate. Please install either dependency by adding one of those to your Gemfile.

Pagination links will only be included in your response if you are using a JSON-API adapter, the others adapters doesn't have this feature.

ActiveModel::Serializer.config.adapter = :json_api

ex:

{
  "data": [
    {
      "type": "articles",
      "id": "1",
      "attributes": {
        "title": "JSON API paints my bikeshed!",
        "body": "The shortest article. Ever.",
        "created": "2015-05-22T14:56:29.000Z",
        "updated": "2015-05-22T14:56:28.000Z"
      }
    }
  ],
  "links": {
    "first": "?page=1&per_page=1",
    "prev": "?page=2&per_page=1",
    "next": "?page=4&per_page=1",
    "last": "?page=13&per_page=1"
  }
