Using the TinyMCE .zip package with the Ruby on Rails framework

Self-hosted instances of TinyMCE can be integrated into Ruby on Rails projects. This procedure creates a basic Ruby on Rails application containing a TinyMCE editor.

Prerequisites

This procedure requires the following programs:

Procedure

On a command line or command prompt:

Create a new Ruby on Rails project.
```
rails new myTinySite
```
Navigate into the project directory.
```
cd myTinySite/
```
Create a new Rails controller, such as:
```
rails generate controller Welcome index
```
This creates a controller named Welcome with an action named index.
Set the project home page to index.
1. Using a text editor, open config/routes.rb, such as:
  nano config/routes.rb
2. Add root 'welcome#index' to set index as the project home page. For example:
  Rails.application.routes.draw do get 'welcome/index' root 'welcome#index' end

Add the following lines within the <head> element of app/views/layouts/application.html.erb to automatically include TinyMCE on pages using the application layout:

<script src="/path/to/tinymce.min.js"></script>
<script>
  tinymce.init({
    selector: '.tinymce',
    plugins: 'lists link image table code help wordcount'
  });
</script>

Create a <textarea> with the initial content Hello, World! for TinyMCE by adding the following lines to app/views/welcome/index.html.erb:
```
<%= text_area_tag :content, "Hello, World!", :class => "tinymce" %>
```
On a command line, from the project’s root directory, start the Ruby on Rails server.
```
rails server
```

The page containing the TinyMCE will be accessible at http://localhost:<port>/ (default: http://localhost:3000/).
