2. edit file engine.rb of Engine:

 class Engine < ::Rails::Engine isolate_namespace Blorgh initializer "static assets" do |app| app.middleware.insert_before(::ActionDispatch::Static, ::ActionDispatch::Static, "#{root}/public") end end 

3. Edit file .gemspec of engine:

s.files = Dir["{app,config,db,lib,public}/**/*", "MIT-LICENSE", "Rakefile", "README.md"]

4. Using file js in a file index.html.erb of engine:

  <script src="sliderengine/amazingslider.js"></script> 

Result : occur error when run Rails App:

How can use [public] folder in Rails Engine?

Answer 1

您必须将引擎的公用文件夹复制到Rails App的public / blog文件夹中

Answer 2

Hm. Here's how I do it:

Put the js in the assets folder of the engine (I put it under the engine name):

app/assets/javascripts/blorgh/amazingslider.js

Then in the engine add:

#blorg/app/assets/javascripts/blorgh.js
//= require_tree ./blorgh

Then in the app

#application.js
//= require blorgh
