如何在Rails应用程序中重用模型和控制器

Question

We are coming up with a new twitter bootstrap theme for new functionality within our application. Our existing functionality will use the existing theme with models/controllers .

But I would like to re-use the existing models/controllers and use the new twitter bootstrap theme for the new functionality.

How do I go about addressing this and maintain the code bases (the old app will be on host:port1 and new app will be on host:port2)

Edit :

My old rails application under public/javascripts public/stylesheets . Some of the views are under app/views/foos/ Some of the views are under app/views/bars/

I would the new views under app/views/cars/ How should I reference my new index files to point to the new theme/css under app/assets

Answer 1

You can switch between css manifest files. So for new theme it could be like

new_theme.css
 /*
 *= bootstrap_alternative_theme
   ... 
 */

old_theme.css
 /*
 *= bootstrap_original_theme
   ... 
 */   

And layouts/application.html.erb

<% if request.port == port1 %>
   <%= stylesheet_link_tag  "old_theme" %>
<% else %>
   <%= stylesheet_link_tag  "new_theme" %>
<% end %>

To add to benchwarmer answer, you might have the html and also the javascript modified so you can define a new layout and toggle between old and new layout as per your needs.

But for compiling those assets, assuming your assets are not named application.css or application.js, add a line in your application.rb

config.assets.precompile += %w(new.css new.js)
