Question

我对Rails很陌生，对我的问题所在也不了解。几天前才刚开始，现在我正在尝试向特定帖子添加评论。嗯，从技术上讲，这些不是注释，而是当其他人与该请求进行交互时，例如请求A具有日志B，日志C，日志D的更多日志添加到了某个请求，因此它基本上与注释系统相同。

我已经可以创建日志并显示它们了，但是我的主要问题是为正确的请求显示正确的日志。我的日志已经有正确的请求ID，但我不知道如何获取特定请求的特定日志

这是我的historys_controller.rb

class HistorysController < ActionController::Base
  before_action :require_login

  def index 
    @historys = History.where(job_order: 1)
  end

  def require_login
    unless session['user_credentials_id']
      redirect_to '/'
    end
  end
end

它仍设置为1作为临时占位符，并尝试类似

History.where(job_order: @job_order.id)

和

History.where(job_order: params [:id])

不起作用，那我应该放在那儿吗？

编辑

history.rb

class History < ApplicationRecord
    belongs_to :job_order, polymorphic: true
    belongs_to :actor, class_name: "User"
end

routes.rb

Rails.application.routes.draw do
  # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html
  root 'user_sessions#new'

  get '/sign_in', to: 'user_sessions#new', as: :sign_in
  get '/signup' => 'users#signup', as: 'signup_user'
  delete '/sign_out', to: 'user_sessions#destroy', as: :sign_out
  post '/register' => 'users#register', as: 'register_user'

  get '/users/activate/:id' => 'users#activate', as: 'activate_user'
  get '/users/deactivate/:id' => 'users#deactivate', as: 'deactivate_user'

  get '/job_order_tracking_system' => 'job_orders#dashboard', as: 'job_order_tracking_system'
  get '/job_orders/approve_job_order/:id' => 'job_orders#approve_job_order', as: 'approve_job_order'
  get '/job_orders/reject_job_order/:id' => 'job_orders#reject_job_order', as: 'reject_job_order'
  get '/job_orders/start_job_order/:id' => 'job_orders#start_job_order', as: 'start_job_order'
  get '/job_orders/done_job_order/:id' => 'job_orders#done_job_order', as: 'done_job_order'
  get '/job_orders/cancel_job_order/:id' => 'job_orders#cancel_job_order', as: 'cancel_job_order'

  resources :job_orders do
    resources :historys
  end
  resources :users
  resources :offices
  resources :user_sessions, only: [:create, :destroy]
  resources :notifications do
    collection do
      post :mark_as_read
    end
  end
  # resources :historys
end

Answer 1

您想要特定工作订单的历史记录吗？

做

class JobOrder < ApplicationRecord
  has_many :histories
end

然后您可以通过获取所有相关历史记录

@job_order.histories

在您看来，您可以做类似...的事情

<% @job_order.histories.each do |history| %>
  <%= history.name %>
  <%= history.comment %>
  <br/>
<% end %>

偶然地，对“历史”的复数使用正确的拼写...您的控制器应为HistoriesController Rails比您想象的要聪明。

Answer 2

我还注意到您在params和[:id]之间留有一定距离。它应该是这样的：params[:id]。
