Issue with book.publisher.name p105

[mole1066]

On page 107 there is a method to display data from an external table

Although all my other database functions work fine this does not and i
get the following error:

You have a nil object when you didn't expect it!
The error occurred while evaluating nil.name

If I replace the command to use a local table all is fine, it is just
when connecting through the foreign key

Any clues as to why this may be occurring? I am using rails v2.1.0 and
mysql 5.0.5

That specific book doesn't have a publisher?

It was actually to do with a slightly different project I was working
on. Because I hadn't used exactly the same column names, especially
for the foreign key. I therefore had to specify the name of the
foreign key in the belongs_to statement in the model
