Ruby on rails format.html提供了错误数量的参数（2代表1）错误

我试图使用format.html，但它表明我没有足够的参数。我相信它以前在Rails 4.1上工作过。我最近刚升级到4.2.1，现在它无法工作

 if(!params[:search].blank?)
  @company = Company.where("comp_name LIKE ?", "#{params[:search]}%")
  @main_company = @company.first
  if(@main_company.nil?)
    flash.now[:danger] = "Invalid Company Name"
    @company = []
  else
    respond_to do |format|
      format.json do 
       results = @company.map do |company|
          { comp_name: company.comp_name }
        end
        render json: results
      end
      format.html{redirect_to company_path(@main_company)}
      # format.html { redirect_to company_path(@main_company) }
    end
  end
else
  @company = []
end

我收到错误消息：

wrong number of arguments (2 for 1)
Extracted source (around line #18)          



  16 render json: results
  17 end
  18 format.html{redirect_to {company_path(@main_company)}}
  19 # format.html { redirect_to company_path(@main_company) }
  20 end
  21 end

请帮忙！谢谢大家!

以下代码应该适合您

#This should be in modal of company
def search_company_by_name params 
  if params[:search]
    l = Company.where("comp_name LIKE '%#{params[:search]}%'")
  else
    []
  end
end
# controller's action
res = Company.search_company_by_name params
respond_to do |format|
  format.json {render json: res}
end

我希望这能有所帮助。

谢谢！我不理解代码，但我会尽力通读并尽可能地学习。我已经编辑了我的答案。如果这个答案对你们有效，请接受。你好，我正在收到ActionController:：UnknownInformation。我还将模型函数更新为self.search\u company\u by\u name。谢谢你的帮助！
