def add_to_cart
begin
product = Product.find(params[:id])
rescue ActiveRecord::RecordNotFound
logger.error("Attempt to access invalid product #{params[:id]}")
flash[:notice] = "Invalid product"
redirect_to :action => :index
else
@cart = find_cart
@cart.add_product(product)
end
end
~~~~~~~~~~~
When I intentionally pass a bad product id via the URL string: http://localhost:3000/store/add_to_cart/woot
instead of rescue picking up the exception, I get the big nasty error page:
~~~~~~~~~~~
ActiveRecord::RecordNotFound in StoreController#add_to_cart
Couldn't find Product with ID=woot

<p>
<em>Pragmatic Project Automation</em> shows you how to improve the
consistency and repeatability of your project's procedures using
automation to reduce risk and errors.
</p>
<p>
Simply put, we're going to put this thing called a computer to work
for you doing the mundane (but important) project stuff. That means
you'll have more time and energy to do the really
exciting---and difficult---stuff, like writing quality code.

<p>
Pragmatic programmers use feedback to drive their development and
personal processes. The most valuable feedback you can get while
coding comes from unit testing.
</p>
<p>
Without good tests in place, coding can become a frustrating game of
"whack-a-mole." That's the carnival game where the player strikes at a
mechanical mole; it retreats and another mole pops up on the opposite side
of the field. The moles pop up and down so fast that you end up flailing
your mallet helplessly as the moles continue to pop up where you least
expect them.

<p>
This book is a recipe-based approach to using Subversion that will
get you up and running quickly---and correctly. All projects need
version control: it's a foundational piece of any project's
infrastructure. Yet half of all project teams in the U.S. don't use
any version control at all. Many others don't use it well, and end
up experiencing time-consuming problems.
