Pagination Link Do Not Outputted on JSON

[edwinlunando]

Hi, I'm using master branch and JSON adapter. I want to show pagination links, this is my pagination serializer.

# pagination collection serializer
class PaginationSerializer < ActiveModel::Serializer::CollectionSerializer

  def initialize(object, options = {})
    meta_key = options[:meta_key] || :meta
    options[meta_key] ||= {}
    options[meta_key][:pagination] = {
      current_page: object.current_page,
      next_page: object.next_page,
      prev_page: object.prev_page,
      total_pages: object.total_pages,
      total_count: object.total_count
    }
    super(object, options)
  end

end

This is my render code

render json: formulas, serializer: PaginationSerializer, each_serializer: FormulaSimpleSerializer

There no meta key on the result. This happens after upgrading from 0.10.RC3 to master. Any idea?

I tried to dig the old ArraySerializer

def initialize(resources, options = {})
  @root = options[:root]
  @object = resources
  @serializers = resources.map do |resource|
    serializer_class = options.fetch(:serializer) {
      ActiveModel::Serializer.serializer_for(resource)
    }

    if serializer_class.nil?
      fail NoSerializerError, "No serializer found for resource: #{resource.inspect}"
    else
      serializer_class.new(resource, options.except(:serializer))
    end
  end
  @meta     = options[:meta]
  @meta_key = options[:meta_key]
end

and compare it to the new CollectionSerializer

def initialize(resources, options = {})
  @root = options[:root]
  @object = resources
  @serializers = resources.map do |resource|
    serializer_context_class = options.fetch(:serializer_context_class, ActiveModel::Serializer)
    serializer_class = options.fetch(:serializer) { serializer_context_class.serializer_for(resource) }

    if serializer_class.nil?
      fail NoSerializerError, "No serializer found for resource: #{resource.inspect}"
    else
      serializer_class.new(resource, options.except(:serializer))
    end
  end
end

Why there is no meta declaration? Is this expected? What I must do in order to add pagination links?

Come to this rendering page, does it means we cannot use something like PaginationSerializer anymore? Do we need to explicitly put it in render method?

[edwinlunando]

Come to this pull request, seems the pagination documentation on master branch is no longer valid. I can make a PR if you want to fix the docs?

@edwinlunando Yes, a docs PR would be great!
