ActiveAdmin Quill Editor

An Active Admin plugin to use Quill Rich Text Editor in form fields.

Please ⭐ if you like it.

Install

NOTE: Ruby 2.7 is supported until version 1.1.0

After installing Active Admin, add to your Gemfile: gem 'activeadmin_quill_editor' (and execute bundle)

If you installed Active Admin without Webpacker support (default for now):

• Add a SASS/SCSS gem to your Gemfile (ex. gem 'sassc')
• Add at the end of your Active Admin styles (app/assets/stylesheets/active_admin.scss):

@import 'activeadmin/quill_editor/quill.snow';
@import 'activeadmin/quill_editor_input';

• Add at the end of your Active Admin javascripts (app/assets/javascripts/active_admin.js):

//= require activeadmin/quill_editor/quill
//= require activeadmin/quill_editor_input

UPDATE FROM VERSION <= 2.0: please add to your app/assets/stylesheets/active_admin.scss the line @import 'activeadmin/quill_editor/quill.snow';

If you installed Active Admin with Webpacker support:

• Execute in your project root:

yarn add blocknotes/activeadmin_quill_editor

• Add to your app/javascript/packs/active_admin.js:

require('activeadmin_quill_editor')

Usage

In your Active Admin models, form configuration, set the text inputs with as: :quill_editor where needed.

data-options: permits to set quill editor options directly - see options list

If you are using Action Text (has_rich_text) on the same field of the Quill editor please take a look at this workaround to avoid issues.

Examples

Basic usage

# Active Admin article form conf:
  form do |f|
    f.inputs 'Article' do
      f.input :title
      f.input :description, as: :quill_editor
      f.input :published
    end
    f.actions
  end

Toolbar buttons configuration

f.input :description, as: :quill_editor, input_html: { data: { options: { modules: { toolbar: [['bold', 'italic', 'underline'], ['link']] }, placeholder: 'Type something...', theme: 'snow' } } }

ImageUploader plugin

This plugin allows to upload images to the server (instead of storing them in base64 by default), reference here.

# Upload method (to be included in the admin entity configuration)
member_action :upload, method: [:post] do
  result = { success: resource.images.attach(params[:file_upload]) }
  result[:url] = url_for(resource.images.last) if result[:success]
  render json: result
end

# Form field
unless object.new_record?
  plugin_opts = { image_uploader: { server_url: upload_admin_post_path(object.id), field_name: 'file_upload' } }
  f.input :description, as: :quill_editor, input_html: { data: { plugins: plugin_opts } }
end

For the relevant files of the upload example see here. Consider that this is just a basic example: images are uploaded as soon as they are attached to the editor (regardless of the form submit), it shows the editor only for an existing record (because of the upload_admin_post_path) and it doesn't provide a way to remove images (just deleting them from the editor will not destroy them, you'll need to implement a purge logic for that).

If you use this component just star it. A developer is more motivated to improve a project when there is some interest. My other Active Admin components.

Or consider offering me a coffee, it's a small thing but it is greatly appreciated: about me.
