Help with with displaying a selected list.

Hello. I call a find_all_by_subject("action") which returns 2 videos and displays them properly. But when I add @video_pages, @videos = paginate :videos, :per_page => 10 so I can paginate the videos, it displays ALL the videos as if I selected list videos. Can someone please tell me what I am doing wrong? Thank you.

selectaction.rhtml

<table>   <tr>   <% x = 0 %>   <% for video in @videos %>     <td><%= link_to(image_tag("videos/#{video.video_thumbnail}",                                :size => '132x99',                                :border => 5,                                :id => 'thumbnail'),                     url_for(:action => 'show', :id => video)                    )          %><br>     <b>Title:</b> <%= h video.title %><br>     <% x = x + 1 %>     <% if x % 2 == 0 %>       <%= "</td></tr><tr>" %>     <% else %>       <%= "</td>" %>     <% end %> <% end %> </tr> </table>

<%= link_to 'Previous page', { :page => @video_pages.current.previous } if @video_pages.current.previous %> <%= link_to 'Next page', { :page => @video_pages.current.next } if @video_pages.current.next %>

Controller class VideosController < ApplicationController   def index     list     render :action => 'list'   end

  # GETs should be safe (see URIs, Addressability, and the use of HTTP GET and POST)   verify :method => :post, :only => [ :destroy, :create, :update ],          :redirect_to => { :action => :list }

  def list     @video_pages, @videos = paginate :videos, :per_page => 10   end

  def show     @video = Video.find(params[:id])   end

  def new     @video = Video.new   end

  def create     @video = Video.new(params[:video])     if @video.save       flash[:notice] = 'Video was successfully created.'       redirect_to :action => 'list'     else       render :action => 'new'     end   end

  def edit     @video = Video.find(params[:id])   end

  def update     @video = Video.find(params[:id])     if @video.update_attributes(params[:video])       flash[:notice] = 'Video was successfully updated.'       redirect_to :action => 'show', :id => @video     else       render :action => 'edit'     end   end

  def destroy     Video.find(params[:id]).destroy     redirect_to :action => 'list'   end

  def selectaction     @videos = Video.find_all_by_subject("action")     @video_pages, @videos = paginate :videos, :per_page => 10   end

end

def selectaction    @videos = Video.find_all_by_subject("action")    @video_pages, @videos = paginate :videos, :per_page => 10 end

I think you need to put the conditions on the paginate request. In the 2nd line of the selectation action, your previous value of the variable "videos" is overwritten.

I don't have the syntax here, though. I'll send it out later. I think it's something like:    @video_pages, @videos = paginate :videos, :per_page => 10, :conditions => 'subject = action'

Cheers Mohit.

OK, here's the example:        @video_pages, @videos = paginate(:videos,                                       :per_page => 20,                                       :conditions => @condition,                                       :conditions => ['subject = ?', 'action']                                       ) Cheers Mohit.
