Paginate Multiple Models in Kaminari

Question

I'm creating a search page that will do an application wide search on users, posts, and comments. I currently have:

# POST /search
def index
  query = params[:query]
  @users = User.search(query).page(params[:page])
  @posts = Post.search(query).page(params[:page])
  @comments = Comment.search(query).page(params[:page])

  respond_to do |format|
    format.html
  end
end

However I'm really trying to get something where all the results are mixed together then paginated. What are some of the strategies for doing paginated search like this? Thanks!

Ever since this commit: https://github.com/amatsuda/kaminari/commit/f9f529fb68ab89feea38773a4c625c1b14859128

You can do the following

In your view you can do this:

<%= paginate @users, :remote => true, :param_name => "user_page" %>
<%= paginate @posts, :remote => true, :param_name => "post_page" %>
<%= paginate @comments, :remote => true, :param_name => "comment_#{some_post_id}_page" %>

and then in your controller you can refer to them in this way:

@users = User.search(query).page(params[:user_page])
@posts = Post.search(query).page(params[:post_page])
@comments = Comment.search(query).page(params[:comment_page])

and your view's js.erb you might have something like:

$('#posts').html('<%= escape_javascript render(@posts) %>');
$('.table-pager').html('<%= escape_javascript(paginate(@posts, :remote => true).to_s) %>');
