Rails: pause Metasearch quando scope e paginate?

Question

Ho una serie di foto ricercabile, e voglio limitare i risultati per la pagina di indice per quelli che sono pubblici (cioè non appartengono ad una collezione privata, aka. :collection_id=>nil).

ho il seguente campo di applicazione nel mio modello:

scope :community, where(:collection_id => nil)

Ho il seguente nel mio controller:

def index
  @search = Photo.community.search(params[:search])
  @photos = @search.page(params[:page]).per(20)
end

sto usando Kaminari per impaginare i risultati.

Quando cerco foto senza ambito (cioè Photo.search(params[:search])) funziona benissimo. Tuttavia, quando cerco le foto con questo impaginazione ambito rompe la ricerca. La prima mostra di pagina correttamente, ma quando vado a un'altra pagina non ci sono risultati. Per verificare questa localmente ho cambiato impaginazione a 1 per pagina ed ancora non importa quello che cerco di tutte le pagine dopo la prima pagina mostrano alcun risultato, anche se il Paginator indica che ci sono molte più pagine di risultati.

Non ho idea di come eseguire il debug e risolvere questo problema, e vorrei davvero bisogno di aiuto. Ecco lo SQL dal registro di sviluppo:

Per un carico normale della pagina di indice (non di ricerca):

Ancora una volta nota che nei registri di cui sopra ho esposto impaginazione a 1 per pagina in modo da poter vedere se il Paginator sta mostrando il giusto numero di risultati, e lo è. Per esempio, se cerco qualcosa So che ci sono 3 partite in una sola per ogni pagina del Paginator dice che ci sono tre pagine di risultati, tuttavia le pagine 2 e 3 sono vuoti.

Sono completamente perplesso, tutto l'aiuto sarebbe molto apprezzato.

Answer 1

Prova ad aggiungere la vostra portata come un metodo di ricerca.

class Photo < ActiveRecord::Base
  scope :community, where(:collection_id => nil)
  search_methods :community
end

class PhotosController < ActiveRecord::Base
  def index
    params[:search][:community] => true
    @search = Photo.search(params[:search])
    @photos = @search.page(params[:page]).per(20)
  end
end

Non uso kaminari me stesso, quindi non posso dire per certo, ma so che i documenti dicono MetaSearch da utilizzare search_methods al fine di utilizzare gli ambiti nelle ricerche.

Answer 2

funziona per me con gli attuali più recenti gemme (meta_search 1.0.4, kaminari 0.12.4).

Come l'autore di Kaminari gemma, suppongo alcune vecchie versioni di Kaminari forse non funziona con meta_search. Io in realtà risolto diversi bug che possono causare questo tipo di problema.

Quindi, si può si prega di aggiornare il vostro gioiello Kaminari e riprovare?
