ruby-on-rails – 如何使用react-rails与webpacker？

2019年7月2日 275次阅读

我用webpacker创建了示例项目react-rails.但显示错误“未捕获的ReferenceError：未定义人员”.帮帮我如何使用react-rails与webpacker？

我执行的处理如下.

Rails版本

$rails -v
Rails 5.0.2

宝石版

react-rails (2.1.0)
webpacker (1.1)

创建Rails项目

$rails new example

将webpacker和react-rails添加到Gemfile

gem 'webpacker', github: 'rails/webpacker'
gem "react-rails"

安装webpacker并做出反应

$rails webpacker:install
$rails webpacker:install:react
$rails generate react:install

创建控制器

$bin/rails g controller home

添加路线

config/routes.rb
root "home#index"

添加反应成分

$bin/rails g react:component person name --es6

添加react_component标记

app/views/home/index.html.erb
<%= react_component("Person", { name: "Hello" }) %>

将javascript_pack_tag添加到application.html.erb

app/views/layouts/application.html.erb
<%= javascript_pack_tag 'application' %>

运行服务器

$bin/rails s
$bin/webpack-dev-server

显示错误控制台

VM27375:1 Uncaught ReferenceError: Person is not defined
    at eval (eval at module.exports (fromGlobal.js?fc31:13), <anonymous>:1:1)
    at module.exports (fromGlobal.js?fc31:13)
    at Object.getConstructor (fromRequireContextWithGlobalFallback.js?cbbb:16)
    at Object.mountComponents (index.js?c0e8:82)
    at HTMLDocument.ReactRailsUJS.handleMount (index.js?c0e8:124)
    at HTMLDocument.dispatch (jquery.self-bd7ddd3….js?body=1:5227)
    at HTMLDocument.elemData.handle (jquery.self-bd7ddd3….js?body=1:4879)

示例项目

最佳答案 将app / javascript / components / person.js重命名为app / javascript / components / Person.js(例如,大写)

或者使用react_component(‘person’).

TLDR;资本化问题.
