I tried another way and it was working,

In Controller

areas = Area.all

options = { 
            links: paginate(pagy), 
            params: { current_user: @current_user } 
          }

render json: AreaSerializer.new(areas, options),
       status: ok

In serializer

attributes :nodes do |area, params|
  area.users.where.not(id: params[:current_user].id)
end

And the links key is rendering automatically in Serializer.

Example output received by front-end:

{
  data: [
    {},
    {} // areas hash
  ],
  links: {
    first: "",
    last: "",
  }
}

Use something like this:

render json: AreaSerializer.new(
               Area.all, 
               { params: { paginate: paginate(pagy), current_user: @current_user } }
    ), status: ok

Serializer

attributes :nodes do |area, params|
  ...
  params[:current_user]
  params[:paginate]
  ...
end

So that do you think? – Mykhailo Melnyk Dec 05 '19 at 09:04
Here paginate(pagy) = {links: {first: " ", next: " ", last: " "}}, if i follow like u said, links are not rendering automatically. – Srimathi G Dec 06 '19 at 09:07
