Rails: Metasearch bricht beim Scoped und Pagined?

Question

Ich habe eine durchsuchbare Reihe von Fotos, und ich möchte die Ergebnisse für die Indexseite auf die öffentlichen Einrichtungen beschränken (dh nicht zu einer privaten Sammlung, auch bekannt als auch, auch bekannt. :collection_id=>nil).

Ich habe den folgenden Bereich in meinem Modell:

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

Ich habe Folgendes in meinem Controller:

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

Ich benutze Kaminari, um die Ergebnisse zu pagieren.

Wenn ich unbeschwerte Fotos suche (dh Photo.search(params[:search])) es funktioniert gut. Wenn ich jedoch mit dieser Zielfernrohr -Pagination nach Fotos suche, bricht die Suche. Die erste Seite wird korrekt angezeigt, aber wenn ich zu einer anderen Seite gehe, gibt es keine Ergebnisse. Um dies lokal zu testen, habe ich die Pagination auf 1 pro Seite geändert und immer noch, egal was ich nach der ersten Seite nach irgendwelchen Seiten suche, zeigen keine Ergebnisse, obwohl der Paginator angibt, dass es noch viele weitere Seiten mit Ergebnissen gibt.

Ich habe keine Ahnung, wie ich dies debuggen und beheben soll, und ich würde wirklich Hilfe verwenden. Hier ist der SQL aus dem Entwicklungsprotokoll:

Für eine normale Last der Indexseite (keine Suche):

Beachten Sie erneut, dass ich in den oben genannten Protokollen die Pagination auf 1 pro Seite festgelegt habe, damit ich sehen kann, ob der Paginator die richtige Anzahl von Ergebnissen anzeigt, und es ist so. Wenn ich beispielsweise nach etwas suche, von dem ich weiß, dass es 3 Übereinstimmungen für eine pro Seite gibt, gibt der Paginator an, dass es drei Seiten mit Ergebnissen gibt, jedoch die Seiten 2 und 3 leer sind.

Ich bin völlig ratlos, jede Hilfe wäre sehr geschätzt.

Answer 1

Fügen Sie Ihren Bereich als Suchmethode hinzu.

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

Ich benutze Kaminari selbst nicht, also kann ich nicht genau sagen, aber ich weiß, dass die Metasearch -Dokumente sagen, dass sie Search_methods verwenden sollen, um Scopes in Suchanfragen zu verwenden.

Answer 2

Es funktioniert für mich mit den aktuellen neuesten Edelsteinen (meta_search 1.0.4, Kaminari 0.12.4).

Als Autor von Kaminari Gem, ich nehme an, einige ältere Versionen von Kaminari funktionieren möglicherweise nicht mit meta_search. Ich habe tatsächlich mehrere Fehler behoben, die diese Art von Problem verursachen können.

Können Sie bitte Ihr Kaminari -Edelstein aktualisieren und erneut versuchen?
