Ilya and noluckmurphy…

I was having the same trouble initially described by noluckmurphy: undefined method `multi_search’ for MyModel:Class. I hunted down the trail of discovery and was able to solve my dilemma using your discussion.

In the end, I wrote a blog entry about it. Hopefully it will help others with the same troubles.

Thanks Ilya for the great code, and both of you guys for helping me solve the problem.

Doh! Glad you finally got it working. :)

Fixed. I was incorrectly passing my @collection to my partial. Something (my guess is the callback w/in the PagingEnumerator) was causing the partial itself to be rendered multiple times (even though it wasn’t inside any loops).

“results”, :collection => @collection) %>

is now…

“results”, :locals => {:collection => @collection}) %>

Murphy, are you sure you don’t have a rogue loop in there somewhere? :)

Take a look at the example on the plugin page. If all else fails, send me a link to a pastie of your current controller.

In general, on the last page of results if there are N results (N < :page_size), those results will be printed correctly N times (in the same manner as I’ve described above).

As far as I can tell w/ breakpoints and such, the ‘each’ method in paging_enumerator.rb “seems” to be working correctly–the search results are iterated and printed correctly. But why does it happen N more times on that same page? It’s blowing my mind!

Anyway, my apologies once again for my Rails/Ruby noobishness.

Thanks for all your help this far, Ilya.

Say my result set includes 11 results. Page-size is set to 10 so this yields 2 pages.

On page one, the output is:

Result 1
Result 2
Result 3
…
Result 10

Result 1
Result 2
Result 3
…
Result 10
……

This repeats until the Result 1 - 10 block is printed ten (10) times.

On page two, Result 11 is printed once (as desired). My question is…how should I be interacting with the PagingEnumerator (or its @results ActsAsFerret::SearchResults component). In the above example, the @collection is the PagingEnumerator and @collection.results is the SearchResults component.

Sorry if I’m not using the correct terminology. This is my first project with Rails or Ruby.

Murphy, I’m a little confused, the problem is that the same results are printed on each page? If so, are you passing in the :page parameters correctly?

Wow. I screwed that up!

The view code that’s missing above is

@collection.each do |result|
search_result_name(result)
end
