Question

发出请求的按钮：

<%= link_to business_domain.name, data_services_fetch_by_business_domain_path(:business_domain_id => business_domain.id, :data_services => @data_services), :remote => true %>

routes.rb中的路由：

get "data_services_fetch_by_business_domain" => 'data_services#fetch_by_business_domain', :as => :data_services_fetch_by_business_domain

控制器方法：

  def fetch_by_business_domain
    @data_services_for_domain = BusinessDomain.find(params[:business_domain_id]).data_services
    params[:data_services] & @data_services_for_domain

    respond_to do |format|
      format.js { render :action => display_data_service_records.js.erb }
    end
  end

从控制器方法引用的

display_data_service_records.js.erb：

$("#data-service-listings").html("<%= escape_javascript(render partial: 'listings', locals: { data_services: @data_services } ) %>");

应该更新的部分：

<div class="well" id="data-service-listings">
...
</div>

上面是否存在错误，或者这种方法是否存在根本错误？感谢。

如果你看一下你做过的路线

get "data_services_fetch_by_business_domain" => 'data_services#fetch_by_business_domain', :as => :data_services_fetch_by_business_domain

您正在制作包含获取请求的路线，但如果您想发送一些数据，则应使用 发布请求。

将您的网址更改为

post "business_domain/:business_domain_id" => 'data_services#fetch_by_business_domain', :as => :data_services_fetch_by_business_domain

你的link_to看起来像是：

<%= link_to business_domain.name, data_services_fetch_by_business_domain_path(:business_domain_id => business_domain.id, :data_services => @data_services),method: :post, remote: true %>

您可以params[:data_services]访问data_services数组，params[:bussiness_domain_id]访问bussiness_domain_id
