我希望用户能够轻松找到一个系列,所以想要设置方面.我已按照 seachkick的指示进行操作,一切正常,但是当我设置Facets时,我得到以下作为返回.我想让它像他们的文档一样.希望有人能提供帮助.

我在myapp.com/movies中得到这个

{
  "name"=> {
    "_type"=> "terms","missing"=> 0,"total"=> 1,"other"=> 0,"terms"=> [
      {
        "term"=> "Bloop","count"=> 1
      }
    ]
  },"imdb"=> {
    "_type"=> "terms","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

解决方法

我终于通过以下方式实现了它.不确定它是否是最好的方法,但它的工作原理！希望它有所帮助,如果您有改进或建议,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,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 %>
