[Rails] "Undefined method" problem in "Agile Web Development With Rails"

[David Mitchell]

For some reason your object "item" has the value 2395.0, and is a
floating point object.  Without having the Agile book at my
fingertips, from memory it's supposed to have a price attribute with
that value.

At a guess, you could be setting @items to an individual item, rather
than a collection of items.  That would be consistent with the error
you're seeing.

Have a look at your controller code where you set @items to something;
the problem's probably going to be right around there.
