Webware for Python

Part 2:

Since my site also has top level directories such as Graphics/ JavaScript/ 
etc. as well as a StyleSheet.css in the main directory, I need a convenient 
way to refer to these from subdirectories.

I do this by prepending a string I call the "root dir" to my relative links:

	def rootDir(self):
		'''
		Returns the root directory of the site appropriate for prepending to 
relative paths, such as Graphics/foo.gif. Will return '', '../', '../../', etc.
		'''
		parts = self.request().urlPath().split('/')
		numExtraParts = len(parts) - parts.index('MyContext') - 2
		return '../' * numExtraParts

So I might have a link that looks like this:
     '%sStyleSheet.css' % self.rootDir()

My host name, WebKit adapter name and context name can change at any time 
and the existing code will work fine since I use ../

Upon deployment to the production environment, I could leave this as is, or 
change rootDir() to return 'http://www.host.com/'.
