UPDATE: It's a gem!

This helper has finally been moved into a gem called nav_lynx!

http://rubygems.org/gems/nav_lynx

Thanks to @brianjlandau and @reagent for getting that set up and tested!

Behold, the nav_link:

Retaining line numbers with the Rails asset pipeline

By default the Rails 3 asset pipeline uses the Uglifier gem to optimize and minify your Javascript. One of its many optimisations is to remove all whitespace, turning your Javascript into one very long line of code.

Whist removing all the newlines helps to reduce the file size, it has the disadvantage of making your Javascript harder to debug. If you've tried to track down Javascript errors in minified Javascript files you'll know the lack of whitespace does make life harder.

Luckily there is a simple solution: to configure Uglifier to add newlines back into the code after it performs its optimisations. And if you're serving your files correctly gzip'd, the newlines add only a small increase to the final file size.

You can configure Uglifier to add the newlines by setting the following in your Rails 3 config/production.rb file:

Proposal for Improving Mass Assignment

For a while, I have felt that the following is the correct way to improve the mass assignment problem without increasing the burden on new users. Now that the problem with the Rails default has been brought up again, it's a good time to revisit it.

Sign Allowed Fields

When creating a form with form_for, include a signed token including all of the fields that were created at form creation time. Only these fields are allowed.

To allow new known fields to be added via JS, we could add:
