ruby-on-rails - Controller 中的 ROR + NoMethodError(尝试调用私有(private)方法)

Question

在我的代码中“

NoMethodError (Attempt to call private method): app/controllers/project_evaluations_controller.rb:94:in `calculate'"

发生。 SampleCode : For Controller::Index & Show 方法未提及。

class ProjectEvaluationsController < ApplicationController
  skip_before_filter :verify_authenticity_token, :only => [:index, :show]
  def calculate
    @project_id = params[:id]
    @costs_last_calculated = Time.now.utc
    @total_internal_hours = 10
    @total_external_hours = 20
    @project_evaluation.update(:internal_hours => @total_internal_hours, :external_hours => @total_external_hours, :costs_last_calculated => @costs_last_calculated)
        render :action=>"show"
  end
end

路线:

  resources :project_evaluations do
      match "calculate", :on => :collection
    end

建议任何解决方案!!!

update 是 Rails 中 Active Record 对象的私有(private)方法。您想改用 update_attributes。
