Kaminari ajax，它不起作用，rails 3.1和Mongoid

Question

I'm following https://github.com/amatsuda/kaminari_example/commits/ajax . I'm using kaminari 0.12.4. (I had check with 0.13.0 and and does not work). Without ajax does works fine.

I have in users_helper.rb

module UsersHelper
  def link_to_next_page(scope, name, options = {}, &block)
    param_name = options.delete(:param_name) || Kaminari.config.param_name
    link_to_unless scope.last_page?, name, {param_name => (scope.current_page + 1)}, options.merge(:rel => 'next') do
  block.call if block
  end
 end
end

I have in my users_controller the next method:

def followers
 @user = User.find(params[:user])
 @followers = @user.followers_by_type("user")
 @followers = Kaminari.paginate_array(@followers).page(params[:page]).per(1)
respond_to do |format|
  format.js
  format.html { render :layout => 'panel'}# followers.html.erb
  format.json { render json: @followers }
end  

I have in my follower.index.html.erb the next:

<%= render 'followers' %>
<div id="paginator">
<%= link_to_next_page @followers, 'Next Page', :remote => true, :url => { :controller => "users", :action => "followers"} do %>
<span>No More Pages</span>
<% end %>
</div>

I have in partial _followers.html.erb

 <% for followers in @followers%> 
  <div class="followers">
  <%= followers.username %> 
 </div>
  <% end %>

I have in followers.js.erb

//$('#box').html('<%= escape_javascript render(:partial => 'followers') %>');
//$('#box #paginator').html('<%= escape_javascript(paginate(@followers, :remote => true).to_s) %>');
alert ('I am follower.js.erb file');

I have to see a one alert but not seen. Where is the alert? :O. The file index.js.erb does not gets nothing. Where is the problem?

In my log appear working fine the js.erb:

Started GET "/maserranocaceres/followers?page=2" for 127.0.0.1 at 2012-01-31 05:26:44 -0800

Answer 1

it might sound a silly suggestion, but i have had issues like this in the past where changing the order of the formats helps, try:

respond_to do |format|
  format.html { render :layout => 'panel'}# followers.html.erb
  format.json { render json: @followers }
  format.js
end
