Rails6默認再也不使用asset pipeline,改用Webpacker。javascript
文件結構變化:css
下圖是默認生成的文件夾。包含了rails UJS庫, turbolinks, atcivestorage, channelshtml
添加了channels文件夾。java
如何安裝一個packer:webpack
# 例如 rails webpacker:install:stimulus
Appending Stimulus setup code to /Users/.../tailwindapp/app/javascript/packs/application.js append app/javascript/packs/application.js
# 增長了一行代碼import "controllers"
Creating controllers directory create app/javascript/controllers create app/javascript/controllers/hello_controller.js create app/javascript/controllers/index.js Installing all Stimulus dependencies run yarn add stimulus from "."
#安裝依賴包,能夠在yarn.lock中看到詳細說明
一個輕量化的datetime picker。web
包括使用JS和CSSnpm
安裝:app
# using npm install npm i flatpickr --save # 其餘 yarn add flatpickr #cdn也能夠
推薦直接使用元素,或者選擇器:post
// If using flatpickr in a framework, its recommended to pass the element directly flatpickr(element, {}); // Otherwise, selectors are also supported flatpickr("#myID", {}); // creates multiple instances flatpickr(".anotherSelector");
1. 生成一個Post
下面的命令仍然會生成assetpipeline的文件: stylesheets/scaffolds.scss,若是不使用就刪除掉。
rails g scaffold Post title publish_date:date
2. yarn add flatpickr
javascript/packs/application.js內添加:
import flatpickr from "flatpickr";
#只使用flatpickr的CSS樣式
require("flatpickr/dist/flatpickr.css")
#或者使用不一樣的樣式主題
#require("flatpickr/dist/themes/light.css")
document.addEventListener("turbolinks:load", () => {
flatpickr("[data-behavior='flatpickr']", {
altInput: true,
altFormat: "F j, Y",
dateFormat: "Y-m-d"
})
})
在application.html.erb添加:(使用webPacker CSS)
<%= stylesheet_pack_tag 'application', media: "all", ...%>
在對應的視圖文件內添加:
<div> <%= form.text_field :publish_date, data: {behavior: 'flatpickr'}%> </div>
#生成<input data-behavior="flatpickr" type="hidden" name="post[publish_date]" id="post_publish_date" class="flatpickr-input">
