为什么我要为actionController::Parameters错误获取未定义的方法“deep\u merge”?

actioncontroller ruby ruby-on-rails

在我的Rails 5应用程序中,我尝试在控制器中执行此操作:

  def create
    company_params = params.require(:company).permit(
      :name,
      :email,
      :people_attributes => [
        :first_name,
        :last_name
      ]
    ).deep_merge(
      :creator_id => current_user.id,
      :people_attributes => [
        :creator_id => current_user.id
      ]
    )
    @company = current_account.companies.build(company_params)
    if @company.save
      flash[:success] = "Company created."
      redirect_to companies_path
    else
      render :new
    end
  end

但是,由于某种原因,我得到了这个错误:

actionController::参数的未定义方法“deep_merge”:0x007FA24C39CFB0

我这里缺什么?

params ActionController::Parameters

params.methods.grep(/merge/)
=> [:reverse_merge!, :reverse_merge, :merge!, :merge]
