Rails - Oct 2009 - mislav-will_paginate(will_paginate)

mislav-will_paginate(will_paginate) doesn''t work after search.

servers_controller.rb
  def index
    @servers = Server.paginate(:page => params[:page], :per_page => 20,
:order => ''device_id ASC'')
    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @servers }
    end
  end

   def search
       @servers = Server.paginate(:page => params[:page], :per_page =>
20, :order => ''device_id ASC'', :conditions =>
["hostname like ?",
"%"+params[:keyword]+"%"])
       render :action => ''index''
   end

index.html.erb
<%= will_paginate @servers %>

paginate works fine for index, but after search, only first page is
showed,
when I click "next" or "2", the error appears.
ActiveRecord::RecordNotFound (Couldn''t find Server with ID=search):
  app/controllers/servers_controller.rb:26:in `show''

It seems like paginate doesn''t know, params[:keyword],
I haven''t done anything for "def show" in
servers_controller.rb.

  def show
    @server = Server.find(params[:id])

    respond_to do |format|
      format.html # show.html.erb
      format.xml  { render :xml => @server }
    end
  end

How can I resolve this issue?

Check your routing and URLs.  I suspect they don''t match for search.

I added it to routes.rb
map.search ''/search'', :controller =>
''servers'', :action => ''search''
But I receive different error at this time,
TypeError in ServersController#search
can''t convert nil into String

It seems like paginate doesn''t no what keyword has been used for search
on next page,
so I changed view from <%= will_paginate @servers %> to
<%= will_paginate @servers, :params => {:keyword =>params[:keyword]}
%>

":params => {:keyword =>params[:keyword]}" this part is hand the
parameter to the next page.

What I have done is created search.html.erb instead of using 
index.html.erb,
the only difference between search and index is
":params => {:keyword =>params[:keyword]}"

and added routes.rb, and modified "def search" in
servers_controller.rb
    respond_to do |format|
      format.html # index.html.erb
      format.xml  { render :xml => @servers }
    end

instead of
render :action => ''index''

It works fine now.
Thank you Jeffrey.
