我正在尝试实现一个祈祷请求和祈祷回应表单，就像一个带有评论的微帖子。祈祷请求会像预期的那样被创建和删除，但是当我尝试发布一个祈祷回应时，它只会重新加载页面，没有错误，也没有 Flink 说明发布成功。无论发布是否有效，都会发生这种行为（空白回复没有错误，只是重新加载了页面）当我使用rails控制台时，我能够成功地构建和保存祈祷回复，它显示在rails服务器上。我的表单有什么问题？根据服务器日志，我发现当我尝试发布祈祷回复时，它使用的是RequestsController而不是PrayerResponsesController。我该如何解决这个问题？
下面是我的服务器日志错误：

ActionController::ParameterMissing (param is missing or the value is empty: request
Did you mean?  request_id):

下面是我的代码：
控制器/祷告响应控制器. rb

class PrayerResponsesController < ApplicationController
  before_action :logged_in_user, only: [:create, :destroy]
  before_action :correct_user, only: :destroy

  def create
    @prayer_response = current_user.prayer_responses.build(prayer_response_params)
    if @prayer_response.save
      flash[:success] = "Prayer Response created!"
      redirect_back(fallback_location: root_url)
    else
      render 'static_pages/requests', status: :unprocessable_entity
    end
  end

  def destroy
    @prayer_response.destroy
    flash[:success] = "Prayer Response deleted"
    redirect_back_or_to( root_url, status: :see_other )
  end

  private

    def prayer_response_params
      params.require(:prayer_response).permit(:content, :request_id)
    end

    def correct_user
      @prayer_response = current_user.prayer_responses.find_by(id: params[:id])
      redirect_to root_url, status: :see_other if @prayer_response.nil?

实际上，答案在static_pages_controller.rb文件中...我需要将@prayer_response = current_user.prayer_responses.build添加到requests页面的函数中...

class StaticPagesController < ApplicationController
  def home
    if logged_in?
      @prayer = current_user.prayers.build
      @comment = current_user.comments.build
      @feed_items = current_user.feed.paginate(page: params[:page])
    end
  end

  def help
  end

  def about
  end

  def contact
  end

  def new_public_prayers
  end

  def private_prayers
    if logged_in?
      @private_prayer = current_user.private_prayers.build
    else
      redirect_to root_url
    end
  end

  def requests
    if logged_in?
      @request = current_user.requests.build
      @prayer_response = current_user.prayer_responses.build
    else
      redirect_to root_url
    end
  end

end

这确保了在建立新的祈祷React等时遵循了正确的控制器。
