Does anyone have experience with will_paginate?
I''m trying to use it with acts_as_ferret.
routes.rb
...
map.search ''/search'', :controller =>
''notes'', :action => ''search''
notes.rb
...
acts_as_ferret :fields => [ ''body'' ]
notes_controller.rb
...
def search
if params[ :query ]
@query = params[ :query ]
@notes = Note.find_with_ferret @query, :page => params
[ :page ], :per_page => 3
end
respond_to do |format|
format.html # search.html.erb
format.xml { render :xml => @notes }
end
end
notes/index.html.erb
...
<% if @notes.length > 1 %>
<% form_tag :action => ''search'', :patient_id =>
@patient.id, :method
=> ''get'' do %>
<%= text_field_tag :query, nil, :size => 20 %>
<%= submit_tag "Search" %>
<% end %>
<% end %>
notes/search.html.erb
...
<ul>
<% @notes.each do |note| %>
<li><%= link_to note.body, notes_path( note.id ) %> </li>
<% end %>
</ul>
<%= will_paginate @notes, :params => { :patient_id => @patient.id }
%>
The pagination list shows fine, but when clicking on a page number, I
get the error:
You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each
Extracted source (around line #8):
5: <em>Searching for <%= @query %>...</em>
6:
7: <ul>
8: <% @notes.each do |note| %>
9: <li><%= link_to note.body, notes_path( note.id ) %> </li>
10: <% end %>
11: </ul>
The other, really dumb question I have is that the links generated by
notes_path( note.id ) take the form ...notes.32 whereas my show method
wants notes/32. How can I get notes_path to correctly format?
Many TIA,
Craig

This looks promising: http://www.mckinneystation.com/2007/08/20/pagination-with-acts_as_taggable_on_steroids-acts_as_ferret-and-will_paginate/ You basically need to wrap the results from find_with_ferret in a WillPaginate collection so that the will_paginate helper knows what to do with it. This is ordinarily accomplished with the "paginate" method when using ordinary finds, which find_with_ferret is not, unfortunately. By the way, Sphinx is generally considered better than Ferret for search, and automatically returns will_paginate collections... If notes is a rest resource, you might want to try note_path(note) instead of notes_path.

Thanks, David. I ran across that link in my searches today, but the "UPDATE (6/6/08): This is out of date for the latest Rails and will_paginate" threw me off a little. I''ll give Sphinx a try--I''m certainly not married to act_as_ferret.
