One thing I don't understand about unobtrusive javascript
I like the idea of separating functionality and this seems like the way of the future. But I'm used to integrating javascript inside loops in an embedded language like Rails ERB or PHP, where I can use the ID of a particular object as a reference in the javascript. Rails example: <% @comments.each do |comment| %> <div id="comment_<%...

Shouldn't there be a Rails plugin convention for requiring javascripts and/or stylesheets?
For example: I want to create a new kind of tag (fancy_input_tag) for use from any view as a plugin. No problem, I can do this. The trick is my tag requires the use of stylesheets and javascripts. As usual, my rake task copies these assets into their appropriate public folders. Having built this plugin myself, there’s no real issu...

Speeding up RSpec tests in a large Rails application
I have a Rails application with over 2,000 examples in my RSpec tests. Needless to say, it's a large application and there's a lot to be tested.

I don't want to reinvent the wheel, but I will if I cannot find an existing solution. The template system looks like this: {block:Text} <li class="post text"> {block:Title} <h3><a href="{Perm...
