  • Be sure to use a sync-name which is unique, since it will be a container name.

      慣例是 docker-sync 的 container name 後綴都是 -sync
  • split your docker-compose configuration for production and development (as usual)
  • ...9 more annotations...
  • production stack (docker-compose.yml) does not need any changes and would look like this (and is portable, no docker-sync adjustments).
  • docker-compose-dev.yml ( it needs to be called that way, look like this ) will override

      開發版的 docker-compose-dev.yml 僅會覆寫 production docker-compose.yml 的 volumes 設定，也就接上 docker-sync.yml 的 volumes，其它都維持不變
  • nocopy # nocopy is important
  • nocopy # nocopy is important
  • docker-compose -f docker-compose.yml -f docker-compose-dev.yml up
  • add the external volume and the mount here
  • In case the folder we mount to has been declared as a VOLUME during image build, its content will be merged with the name volume we mount from the host

      如果在 Dockerfile 裡面有宣告一個 volume，那麼在 docker build 的時候這個 volume mount point 會被記錄起來，在 container 跑起來的時候，會將 host (server) 上的同名的 volume 內容合併進來 (取代)。也就是說 container 跑起來的時候，會去接上已經存在的既有的 host (server) 上的 volume。
  • enforce the content from our host on the initial wiring
  • set your environment variables by creating a .env file at the root of your project

  • jquery-ujs wires event handlers to eligible DOM elements to provide enhanced functionality.
  • ...11 more annotations...
  • In most cases, the eligible DOM elements are identified by HTML5 data attributes.
  • using JavaScript to progressively enhance the user experience for capable browsers without negatively impacting clients that do not support or do not enable JavaScript.

      讓 user 有更好體驗，但是也不影響到那些沒有 JS 支援的 user
  • jquery-ujs attaches a handler to links with the data-method attribute
  • When the link is clicked, the handler constructs an HTML form along with a hidden input that sets the _method parameter to the requested HTTP verb
  • jquery-ujs attaches a handler to links or forms with the data-confirm attribute that displays a JavaScript confirmation dialog
  • Users double click links and buttons all the time.
  • Links and buttons that have a data-disable-with attribute get a click handler that disables the element and updates the text of the button to that which was provided in the data attribute and disables the button.

      優雅地處理了使用者重複點擊傳送按鈕的問題。
  • If the action is performed via AJAX, the handler will re-enable the button and reset the text when the request completes.
  • Thanks to jquery-ujs and Rails’ respond_with, setting remote: true is likely the quickest way to get your Rails application making AJAX requests.
  • support both AJAX and standard requests at the same time.
  • Cross-Site Request Forgery (CSRF) is an attack wherein the attacker tricks the user into submitting a request to an application the user is likely already authenticated to.
