You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: soil_analyses_exchanger.rb
    path of file: ./repos/ekylibre/app/exchangers/agro_systemes
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module AgroSystemes
  class SoilAnalysesExchanger < ActiveExchanger::Base
    category :plant_farming
    vendor :agro_systemes

    SOIL_NATURES = {
      'LIMON SABLEUX' => :si

      zones = LandParcel.where('TRIM(name) ILIKE ?', name.to_s.strip)
      unless zones.any?
        zones = LandParcel.where('TRIM(name) ILIKE ?', '%' + name.to_s.strip + '%')
        unless zones.any?
          zones = LandParcel.where('TRIM(name) ILIKE ?', '%' + name.to_s.strip.gsub(/\s+/, '%') + '%')
