Because it looks to me like they are trying to run the active record
test suite against their database driver (the schema used in the error
messages matches one of the tables used in the active record tests.

I cannot understand why you did not do that before asking here.

You are missing the fundamental nature of ActiveRecord associations.
If you have an order in, for example, @order then the customer is
@order.customer and if you want that customer's first_name then you
can say @order.customer.first_name. There is no need to mess about
with complex queries, such is the magic of Rails.

Have a look at the Rails Guide on ActiveRecord Associations (and the
other guides for that matter) and work right through a good tutorial
such as railstutorial.org (which is free to use online) and you will
be able to answer most of these questions yourself.
