Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

# This is the code from my 'There is No Such Thing as Metaprogramming' talk,
# which premiered at the Arlington, VA Ruby Users Group on Feb 22nd.
# Without the deliver and walk-through to the solution below this example
# will be missing quite an important bit of content (mainly the tracking of
# 'self' while developing the solution, but it still a useful read.

# Here is the Toddler with no metajuju. Note that the developer, as well as
# the code, is completely unuaware of the interpreter. A developer with a
# background in compiled languages would be comfortable looking at this.
