Bootsy is a WYSIWYG editor for Rails based on Bootstrap-wysihtml5 with image uploads using CarrierWave.

Live demo


  • ImageMagick or GraphicsMagick (for MiniMagick);
  • Bootstrap 3 fully installed in your app.


  1. Add Bootsy to your Gemfile and bundle install it:

    gem 'bootsy'
    bundle install
  2. Mount Bootsy at the beginning of your config/routes.rb:

    Rails.application.routes.draw do
    mount Bootsy::Engine => '/bootsy', as: 'bootsy'
  3. Require Bootsy in the asset pipeline:

    In your app/assets/javascripts/application.js, put this after requiring jQuery and Bootstrap:

    //= require bootsy

    In your app/assets/stylesheets/application.css, put this line after requiring Bootstrap:

    *= require bootsy
  4. Add and run migrations:

    bundle exec rake bootsy:install:migrations
    bundle exec rake db:migrate


Just call bootsy_area in your FormBuilder instances, the same way you'd call textarea. Example:

<%= form_for(@post) do |f| %>
  <%= f.label :title %>
  <%= f.text_field :title %>

  <%= f.label :content %>
  <%= f.bootsy_area :content %>

  <%= f.submit %>
<% end %>

Bootsy will group the uploaded images as galleries and associate them to one of your models. For instance, if you have a Post model and you want to use bootsy_area with it, you must include the Bootsy::Container module:

class Post < ActiveRecord::Base
  include Bootsy::Container

Don't forget to ensure the association between your model objects with Bootsy image galleries. For strong_parameters, you must whitelist the bootsy_image_gallery_id parameter in your controller:


def post_params
  params.require(:post).permit(:title, :content, :bootsy_image_gallery_id)

Bootsy with Simple Form builders

You can use bootsy as an input type in SimpleForm::FormBuilder instances. Example:

<%= simple_form_for @post do |f| %>
  <%= f.input :title %>

  <%= f.input :content, as: :bootsy %>

  <%= f.button :submit %>
<% end %>

Editor options

You can customize Bootsy through a hash of editor_options:

Enable/disable features

You can enable and disable features as you like. For instance, if you don't want link and color features:

<%= f.bootsy_area :my_attribute, editor_options: { link: false, color: false } %>

Available options are: :blockquote, :font_styles, :emphasis, :lists, :html, :link, :image and :color.

Alert of unsaved changes

By default Bootsy alerts the user about unsaved changes if the page is closed or reloaded. You can disable this feature with:

<%= f.bootsy_area :my_attribute, editor_options: { alert_unsaved: false } %>


If you don't want to have image uploads, just call bootsy_area in a form builder not associated to a Bootsy::Container model. This way users will still be able to insert images in the text area using an external image URL.


You can set the default editor options, image sizes available (small, medium, large and/or its original), dimensions and more. Create a copy of Bootsy's initalizer file in your config/initializers and feel free to uncomment and change the options as you like.


You can translate Bootsy to your own language. Simply create a locale file for it in your config/locales directory similar to Bootsy's master English file.

You also need to translate Bootsy on the JavaScript side. Just follow this example. Bootsy will try to guess the locale based on the lang attribute of the page's <html> tag. You can set the locale directly by setting a data-bootsy-locale attribute on your <textarea>.
