Rails has a handy truncate helper (which is actually mostly a method added to String ), but it warns you it's not safe to use on html source, it'll cut off end tags and such.

What if you want an HTML safe one? There are a variety of suggested solutions you can google, none of which were quite robust/powerful enough for me.

So I started with my favorite, by Andrea Singh, using nokogiri.

But:

I modified it to not monkey-patch Nokogiri, but be a static method instead (sadly making already confusing code yet more confusing, but I didn't want to monkey patch nokogiri)

	visit('/projects')
	visit(post_comments_path(post))

	=Clicking links and buttons=
	click_link('id-of-link')
	click_link('Link Text')
	click_button('Save')
	click('Link Text') # Click either a link or a button
	click('Button Value')

	# RJS handler was kicked out of Rails 3.1 along with Prototype
	# so, here is a little substitute coz we use it here and there
	#
	# Just save it in some file in the `config/initializers`
	#
	module ActionView
	module Template::Handlers
	class RJS
	# Default format used by RJS.

	// This way you can change the buttons color with a simple `background-color` setting
	// without need to regenerate the whole gradient
