在另一個活動記錄上過濾活動記錄

Question

我對rails很陌生，並試圖解決這個問題。

我有幾個型號：

約會= belongs_to供應商供應商has_many位置通過vendor_locations

我根據區域中的位置過濾一些地圖標記：

    if params[:search].present?
      location_ids = Location.near(params[:search], 50, order: '').pluck(:id)
      @vendor_locations = VendorLocation.includes(:location).where(location_id: location_ids)
    else
      location_ids = Location.near([session[:latitude], session[:longitude]], 50, order: '').pluck(:id)
      @vendor_locations = VendorLocation.includes(:location).where(location_id: location_ids)
    end

我正在嘗試過濾那些與搜索區域中的供應商相關聯的活動APPOINTMENTS。

我試圖用以下內容設置活動記錄：

  def index
if params[:service].blank?
  @appointments = Appointment.includes(:vendor).where(vendors: {id: @vendor_locations.vendor_id})

但那顯然不起作用。 關於如何基於@vendor_locations進行過濾的任何建議？

Answer 1

從vendor_locations中抽取vendor_id來過濾約會：

@vendor_locations = VendorLocation.where(location_id: location_ids)
@appointments = Appointment.
                  includes(:vendor).
                  where vendor_id: @vendor_locations.select(:vendor_id)
