A gem to add in-place-editable fields to your Rails project. It is a wrapper for the Jeditable jQuery plugin, so most options for $.editable() can be passed through the options parameter of the helpers.

• jQuery 1.2.6+ - see jquery-rails for easy integration with your Rails project
• Jeditable

Assuming a Rails 3 project, in your Gemfile, add:

gem 'jeditable-rails'

Suppose you have a User model with a #zip_code attribute.

<%# app/views/users/show.html.erb %>
<h1>View/Edit your profile</h1>
...
<b>Zip Code:</b>
<%= editable_field @user, :zip_code %>

The helpers can be used in any view you like. The field appears as normal text to the user, but when clicked, turns into a form field that will then be submitted back to the server. By default, jeditable-rails requires an update action when a PUT is done to url_for(object), which is generated by default for Rails scaffolds.

Jeditable also requires the server to respond with the new value. For a simple update action, the code will look something like this:

# app/controllers/users_controller.rb
def update
  # update your model
  @user = User.find(params[:id])
  @user.update_attributes!(params[:user])

  format.html {
    if request.xhr?
      # *** repond with the new value ***
      render :text => params[:user].values.first
    else
      redirect_to(@user, :notice => 'User was successfully updated.')
    end
  }
end
