在Rails 4.1中使用Searchkick gem在Elasticsearch中设置构面

Question

我希望用户能够轻松找到系列，因此希望设置构面。我已经按照seachkick的指示进行了，并且一切正常，但是当我设置Facets时，得到了以下回报。我希望它像他们的文档一样。希望有人能帮忙。

我在myapp.com/movies中得到了

{
  "name"=> {
    "_type"=> "terms",
    "missing"=> 0,
    "total"=> 1,
    "other"=> 0,
    "terms"=> [
      {
        "term"=> "Bloop",
        "count"=> 1
      }
    ]
  },
  "imdb"=> {
    "_type"=> "terms",
    "missing"=> 0,
    "total"=> 1,
    "other"=> 0,
    "terms"=> [
      {
        "term" => "http://www.bloop.com",
        "count" => 1
      }
    ]
  }
}

#app/views/movies/index.html.erb
<%= p @series.facets %>

#app/controllers/movies_controller.rb
def index
  query = params[:query].presence || "*"
  @movies = Movie.search(query, page: params[:page],
                                suggest: true,
                                per_page: 20,
                                facets: [:name, :imdb])
end

#db/schema.rb
create_table "movies", force: true do |t|
  t.string   "name"
  t.text     "description"
  t.string   "imdb"
  t.string   "year"
  t.datetime "created_at"
  t.datetime "updated_at"
end

通过执行以下操作，终于使它正常工作。不知道这是否是最好的方法，但是它有效！希望对您有所帮助，如果您有任何改进或建议，请随时告诉我。

# app/models/movie.rb
def self.facets_search(params)
  query = params[:query].presence || "*"
  conditions = {}
  conditions[:year] = params[:year] if params[:year].present?

  movies = Movie.search query, where: conditions, 
    facets: [:year], 
    smart_facets: true, page: params[:page], suggest: true, highlight: true,
    per_page: 10
  movies
end

。

# app/controllers/movies_controller.rb
def index
  @movies = Movie.facets_search(params)
end

。

# app/views/movies/index.html.erb
<% if @movies.facets["year"]["terms"].present? %>
    <div>
        <ul>
        <% @movies.facets["year"]["terms"].each do |filter| %>
          <li><%= link_to "#{filter["term"]} (#{filter["count"]})", "/movies?year=#{filter["term"]}" %></li>
        <% end %>
        </ul>
    </div>
<% end %>
