In-place editing with Twitter Bootstrap for Rails 3/4

This gem is based on X-editable (v1.5.1) which is the new version of Bootstrap Editable.

https://github.com/vitalets/x-editable

See http://vitalets.github.com/x-editable

Add this line to your application's Gemfile:

gem 'bootstrap-editable-rails'

And then execute:

$ bundle

Write the top of app/assets/javascripts/application.js like this:

//= require jquery
//= require jquery_ujs
//= require bootstrap
//= require bootstrap-editable
//= require bootstrap-editable-rails
//= require_tree .

and need to load bootstrap-editable.css at the place where you like.

Follow the documents of X-editable above.

Additional required attribute is resource.

<a href="#" id="username" data-type="text" data-resource="post" data-name="username" data-url="/posts/1" data-original-title="Enter username">superuser</a>

then, sends PUT /posts/1 request with the body:

post[username]=superuser

When using textarea type, textarea_format helper method for formatting line breaks is available.

<a href="#" id="body" data-type="textarea" data-resource="post" data-name="body" data-url="/posts/1" data-original-title="Enter body">
  <%= textarea_format(@post.body) %>
</a>

PostsController receives the parameters

{ "id" => "1", "post" => { "username" => "superuser" } }

and must respond with 2xx (means success) status code if successful.

For example, scaffold works well by 204 because default dataType is json.

def update
  @post = Post.find(params[:id])

  respond_to do |format|
    if @post.update_attributes(params[:post])
      format.html { redirect_to @post, notice: 'Post was successfully updated.' }
      format.json { head :no_content } # 204 No Content
    else
      format.html { render action: "edit" }
      format.json { render json: @post.errors, status: :unprocessable_entity }
    end
  end
end

The scaffold above will not work with jQuery 1.9.0 (included in jquery-rails 2.2.0) because of jQuery's bug.

jquery/jquery#1142

If you use the old version of jQuery, please update jquery-rails to avoid it.
