I implemented a prefix search using the following custom paginator:
@performer_pages = Paginator.new self, Performer.count, 25,
@params[‘page’]
@performers = Performer.find( :all,
:conditions => [“Name >= ?”, params[:prefix] ],
:order => “Name ASC”, :limit =>
@performer_pages.items_per_page,
:offset => @performer_pages.current.offset )
The view (rhtml) creates the previous & next links like so:
<%= link_to ‘Previous page’, { :prefix => params[:prefix], :page =>
@performer_pages.current.previous } if @performer_pages.current.previous
%>
<%= link_to ‘Next page’, { :prefix => params[:prefix], :page =>
@performer_pages.current.next } if @performer_pages.current.next %>
While this creates the previous link appropriately, it creates the
‘next’ link when one is not required (i.e., the result for the ‘next’
page view is empty).
?:-\ Any ideas? Thanks –
