Sir Trevor Rails

A Rails gem for integrating the Sir Trevor JS into your Rails 3.x application.

Usage

Add Sir Trevor to your Gemfile

gem 'sir-trevor-rails'

bundle install 

Require SirTrevor in your application_controller.rb

require 'sir-trevor-rails'

Include Sir Trevor in your application.css file

*= require sir-trevor

Include Sir Trevor in your application.js file

//= require sir-trevor

In your view file for your editable content (must be a 'text' field as we store the JSON here) here we have a field called 'content'

f.sir_trevor_text_area :content

And instantiate a new SirTrevor.Editor instance in your Javascript.

$(function(){
  var editor = new SirTrevor.Editor({ el: $('.sir-trevor-area') });
});

Or for multiple instances:

$(function(){
  var instances = $('.sir-trevor-area'),
      l = instances.length, instance;
  
  while (l--) {
    instance = $(instances[l]);
    new SirTrevor.Editor({ el: instance });
  }
  
});

To render your content (in your view file)

<%= render_sir_trevor(post.content) %>

There's an example Rails 3.2.7 project with all of this already done in the Sir Trevor JS repository.

Generators

Views

To grab all of the default block type partials into your application run the following generator command:

rails g sir_trevor:views

This will copy all of the SirTrevor block partials into app/views/sir-trevor/blocks/

Handling image uploads

We don't provide a default image uploader out of the box, because everyone will have different requirements. Until we provide a full example project, have a look at this gist which allows uploads using CarrierWave and Fog (for S3).

Helper methods

render_sir_trevor
