Hi,
am using this wonderful plugin acts_as_ferret and according to the
tutorial at http://railsenvy.com/2007/2/19/acts-as- ? rial#basic
I worked it out except the pagination feature.
If I have 12 records and I give limit to 10, its correctly displaying 10
records in the first page and is giving the link to the second page too.
But when I go to the next page I find the same 10 records instead of the
next 2 records. Also the result count is showing only 10 instead of 12
thats the right count.
Here''s my code:
Controller:
def search
@users = User.available_users
@user = User.find(session[:user_id])
@query = params[:query] || ''''
@total, @user_profiles = UserProfile.multi_search(@query, [ WorkProfile,
SchoolProfile ], :page => (params[:page]||1))
@pages = pages_for(@total)
unless @query.blank?
@results = UserProfile.find_by_contents @query
end
end
model:
def self.multi_search(q, additional_models = [], options = {})
return nil if q.nil? or q==""
default_options = {:limit => 1, :page => 1}
options = default_options.merge options
# get the offset based on what page we''re on
options[:offset] = options[:limit] * (options.delete(:page).to_i-1)
# now do the query with our options
results = UserProfile.find_by_contents(q, options)
return [results.total_hits, results]
end
view:
<div id="header">
<% if @results -%>
<div id="result">
<table cellpadding="1" cellspacing="1"
width="auto">
<tr valign="top" class="resultdetails">
<td>Your search for <font size="3"><b><%= h
@query %></b></font>
returned <font size="3"><b><%= @results.size
%></b></font> Results:</p>
<ul>
</td>
</tr>
</table>
<% @results.each { |result| -%>
<li><%= link_to result.user.name, :controller =>
''user_profiles'',
:action => ''list_user'', :id=> result.user
%></li><br />
<% if result.user.user_pic %>
<img src="<%=image_path url_for( :controller =>
"user_pics", :action
=> "show_thumb",
:id => result.user.user_pic ) %>" />
<% end %>
<% } -%>
</ul>
<br />
<% end -%>
</div>
</div>
<%= link_to ''Previous page'', { :page =>
@pages.current.previous, :query
=> @query} if @pages.current.previous %>
<%= pagination_links(@pages, :params => { :query=> @query }) %>
<%= link_to ''Next page'', { :page => @pages.current.next,
:query =>
@query} if @pages.current.next %>
Please do let me know how I get my pagination right...
Cheers
Cass

Hi Cass, I think this is a bug in acts_as_ferret. On line 163 in class_methods.rb the limit variable is used but hasn''t been initialised: http://projects.jkraemer.net/acts_as_ferret/browser/trunk/plugin/acts_as_ferret/lib/class_methods.rb In the mean time, aaf actually has paging support in there and that looks like it should work fine. So instead of using :limit and :offset in your options for find_by_contents, drop all your page number calculations and use :per_page and :page. Aaf will then figure out the limit and offset for you.

Use the latest trunk of the plugin, and use the find_with_ferret method with the :multi option instead of multi_search: Model.find_with_ferret query, :page => params[:page], :per_page => 10, :multi => [ Model2, Model3 ] cheers, Jens> > John. > -- > http://www.brightbox.co.uk - UK Ruby on Rails Hosting > > On Wed, 2007-10-03 at 12:52 +0200, Cass Amino wrote: > > Hi, > > > > am using this wonderful plugin acts_as_ferret and according to the > > tutorial at http://railsenvy.com/2007/2/19/acts-as- ? rial#basic > > > > I worked it out except the pagination feature. > > > > If I have 12 records and I give limit to 10, its correctly displaying 10 > > records in the first page and is giving the link to the second page too. > > But when I go to the next page I find the same 10 records instead of the > > next 2 records.
