Paginating_find Help anyone

Hello - I am using paginating_find trying to paginate my records My CallsController index action is

def index      @calls = @current_user.calls.find(:all, :page => {:size => 4, :current => params[:page]})   end

then in the index template for the calls view I have

<ol>             <% @current_user.calls.each do |call| %>                 <li><%= link_to h(call.name), :action => 'show', :id => call %></li>             <% end %>         </ol>         <%= @calls %>         <%= paginating_links(@calls) %>

I only have the <%= @calls %> to see what is in the @calls variable to see if it is available to paginating_find but it isn't. The each.do loop gives links to all the current_user's calls but I get no paginating. I would like 4 per page. If I change the loop to @calls.each do I get calls for all the users which is not what I want and if I change the paginating_links to paginating_links(@current_user.calls) I get the following error

undefined method `page' for #<Class:0x251dacc>

Extracted source (around line #16):

13: <% end %> 14: </ol> 15: <%= @calls %> 16: <%= paginating_links(@current_user.calls) %> 17: 18: 19: So my paginating_links is getting nothing to paginate from what I can see althoug it doew list pages 1 and 2 as links Any help out there please

So the problem is that @calls is not scoped to the @current_user?

Thank you so much for your reply Alexkwolf. Thants how I see it also When I change the line before <%= paginating_links(@current_users.calls) %> to <%= @current_user.calls %> just to see what is in the variable i get the following

        <ol>

                <li><a href="/calls/142">Vanessa</a></li>

                <li><a href="/calls/168">Linnea</a></li>

                <li><a href="/calls/169">Richard</a></li>

                <li><a href="/calls/170">Linea</a></li>

                <li><a href="/calls/171">Mark</a></li>

                <li><a href="/calls/172">My friend</a></li>

                <li><a href="/calls/173">Melvin</a></li>

                <li><a href="/calls/174">Tuesday</a></li>

                <li><a href="/calls/175">Tony lynn</a></li>

                <li><a href="/calls/176">Lyn Lyn</a></li>

                <li><a href="/calls/177">Marjorie</a></li>

        </ol>         #<Call:0x20f4b44>#<Call:0x20f4a54>#<Call:0x20f4950>#<Call: 0x20f4874>#<Call:0x20f4798>#<Call:0x20f46a8>#<Call:0x20f45b8>#<Call: 0x20f44c8>#<Call:0x20f43ec>#<Call:0x20f4310>#<Call:0x20f4234>

        1 <a href="/calls?page=2">2</a> <a href="/calls?page=3">3</a>

       and if I change the line before to just <%= @calls %> i get this avter the loop output

  </ol>         #<PagingEnumerator:0x264d5c8>

        1 <a href="/calls?page=2">2</a> <a href="/calls?page=3">3</a>

So I am not sure what is happening allthough both times I get this interesting output of numbers. Any idea would be greatly appreciated

I think I may have figured it out In my index.rhtml for app/views/calls I tried this code

    <% @recent_calls = @current_user.calls.find(:all, :page => {:size => 4, :current => params[:page]}) %>

        <ol>             <% @recent_calls.each do |c| %>                 <li><%= link_to h(c.name), :action => 'show', :id => c.id %></li>             <% end %>         </ol>         <%= paginating_links(@recent_calls) %>

and it gave me only the 10 calls associated with the current_user so I have to try a few more things and I want to have a previous link and a next link so I don't have to click on the page numbers.

So thanks for the interest and help and thanks to alex wolf for the plug in for paginating_links that works for me
