Rails - Sunspot Solr 搜索 - 显示帖子 3 次

Question

我正在制作一个需要使用搜索表单的 Rails 应用程序。 在我的应用中，用户可以创建一个帖子“广告”，然后指定他希望它是小型、中型还是特色大小的帖子。

在我尝试将 Sunspot Solr Search 合并到我的应用程序之前，它一直运行良好。 不，当我创建一个帖子时，无论是小型、中型还是特色，它都会创建各种尺寸，只要它应该只创建选定的一个。

广告控制器

class AdsController < ApplicationController
  before_action :set_ad, only: [:show, :edit, :update, :destroy]

  # GET /ads
  # GET /ads.json
  def index
    @search_medium = Ad.where(:size => "medium").search do 
      fulltext params[:search]
    end

    @search_featured = Ad.where(:size => "featured").search do 
      fulltext params[:search]
    end

    @search_small = Ad.where(:size => "small").search do 
      fulltext params[:search]
    end


    @ads = Ad.all
    @ads_small = @search_small.results
    @ads_medium = @search_medium.results
    @ads_featured = @search_featured.results

  end

  # GET /ads/1
  # GET /ads/1.json
  def show
  end

  # GET /ads/new
  def new
    @ad = Ad.new
  end

  # GET /ads/1/edit
  def edit
  end

  # POST /ads
  # POST /ads.json
  def create
    @ad = Ad.new(ad_params)
    @ad.user_id = current_user.id

    respond_to do |format|
      if @ad.save
        format.html { redirect_to @ad, notice: 'Ad was successfully created.' }
        format.json { render action: 'show', status: :created, location: @ad }
      else
        format.html { render action: 'new' }
        format.json { render json: @ad.errors, status: :unprocessable_entity }
      end
    end
  end

  # PATCH/PUT /ads/1
  # PATCH/PUT /ads/1.json
  def update
    respond_to do |format|
      if @ad.update(ad_params)
        format.html { redirect_to @ad, notice: 'Ad was successfully updated.' }
        format.json { head :no_content }
      else
        format.html { render action: 'edit' }
        format.json { render json: @ad.errors, status: :unprocessable_entity }
      end
    end
  end

  # DELETE /ads/1
  # DELETE /ads/1.json
  def destroy
      @ad.destroy
      respond_to do |format|
        format.html { redirect_to ads_url }
        format.json { head :no_content }
      end
  end

  private
    # Use callbacks to share common setup or constraints between actions.
    def set_ad
      @ad = Ad.find(params[:id])
    end

    # Never trust parameters from the scary internet, only allow the white list through.
    def ad_params
      params.require(:ad).permit(:title, :url, :preview, :location, :size, :info)
    end
end

1. 默认情况下，本地太阳黑子服务器在端口 8983 上运行，并在那里提供 Web 管理员。您可以通过输入查询作为“：”进行搜索，这将返回太阳黑子内的所有索引记录。

2. 我建议您将 size 字段添加到可搜索定义中，并在不调用 where 方法的情况下进行搜索。
