Active Admin Editor

This is a wysiwyg html editor for the Active Admin interface using wysihtml5.

Demo

Installation

Add the following to your Gemfile:

gem 'active_admin_editor'

And include the wysiwyg styles in your application.css:

//= require active_admin/editor/wysiwyg

Then run the following to install the default intializer:

$ rails g active_admin:editor

Usage

This gem provides you with a custom formtastic input called :html_editor to build out a wysihtml5 enabled input. All you have to do is specify the :as option for your inputs.

Example

ActiveAdmin.register Page do
  form do |f|
    f.inputs do
      f.input :title
      f.input :content, as: :html_editor
    end

    f.buttons
  end
end

Uploads

The editor supports uploading of assets directly to an S3 bucket. Edit the initializer that was installed when you ran rails g active_admin:editor.

ActiveAdmin::Editor.configure do |config|
  config.s3_bucket = '<your bucket>'
  config.aws_access_key_id = '<your aws access key>'
  config.aws_access_secret = '<your aws secret>'
  # config.storage_dir = 'uploads'
end

Then add the following CORS configuration to the S3 bucket:

<?xml version="1.0" encoding="UTF-8"?>
<CORSConfiguration xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
    <CORSRule>
        <AllowedOrigin>*</AllowedOrigin>
        <AllowedMethod>PUT</AllowedMethod>
        <AllowedMethod>POST</AllowedMethod>
        <AllowedMethod>GET</AllowedMethod>
        <AllowedMethod>HEAD</AllowedMethod>
        <MaxAgeSeconds>3000</MaxAgeSeconds>
        <ExposeHeader>Location</ExposeHeader>
        <AllowedHeader>*</AllowedHeader>
    </CORSRule>
</CORSConfiguration>

Configuration

You can configure the editor in the initializer installed with rails g active_admin:editor or you can configure the editor during ActiveAdmin.setup:

ActiveAdmin.setup do |config|
  # ...
  config.editor.aws_access_key_id = '<your aws access key>'
  config.editor.s3_bucket = 'bucket'
end

Parser Rules

Parser rules can be configured through the initializer:

ActiveAdmin::Editor.configure do |config|
  config.parser_rules['tags']['strike'] = {
    'remove' => 0
  }
end

Be sure to clear your rails cache after changing the config:

rm -rf tmp/cache

Heroku

Since some of the javascript files need to be compiled with access to the env vars, it's recommended that you add the user-env-compile labs feature to your app.

1. Tell your rails app to run initializers on asset compilation

   # config/environments/production.rb
   config.initialize_on_precompile = true

2. Add the labs feature

   heroku labs:enable user-env-compile -a myapp

Contributing

1. Fork it
2. Create your feature branch (git checkout -b my-new-feature)
3. Commit your changes (git commit -am 'Added some feature')
4. Push to the branch (git push origin my-new-feature)
5. Create new Pull Request

Tests

Run RSpec tests with bundle exec rake. Run JavaScript specs with bundle exec rake konacha:serve.
