# app/uploaders/redactor2_rails_picture_uploader.rb:33

process :resize_to_limit => [500, -1]

The above example will set the image to have a maximum width of 500px.

After including the desired plugins they can be configured in the redactor config file as normal.

To add it into the editor add 'plugins' attributes to config.js file and specify which ones do you want to use:

  $('.redactor').redactor(
    { "plugins": ['fullscreen',
                'textdirection',
                'clips']
    });

Full details of these can be found at Redactor Plugins

By default redactor2_rails uses the User model.

You may use a different model by:

1. Run a migration to update the user_id column in the
2. Overriding the user class in an initializer.
3. Overriding the authentication helpers in your controller.

Create a new Migration: rails g rename_user_id_to_new_user_id

# db/migrate/...rename_user_id_to_new_user_id.rb

class RenameUserIdToNewUserId < ActiveRecord::Migration
  def up
    rename_column :redactor2_assets, :user_id, :admin_user_id
  end

  def down
    rename_column :redactor2_assets, :admin_user_id, :user_id
  end
end

# config/initializers/redactor2.rb
# Overrides the user class

module RedactorRails
  def self.devise_user
    %s(admin_user) # name of your user class
  end

  # You may override this to support legacy schema.
  # def self.devise_user_key
  #   "#{self.devise_user.to_s}_id".to_sym
  # end
end

# app/controllers/application_controller.rb

class ApplicationController < ActionController::Base
  ...

  def redactor2_authenticate_user!
    authenticate_admin_user! # devise before_filter
  end

  def redactor2_current_user
    current_admin_user # devise user helper
  end
end
