The current list of deprecated
finders follows:
??? find_on_conditions: You should now use find(ids, :conditions => "").
??? find_first: You should now use find(:first, . . .).
??? find_all: You should now use find(:all, . . .).
Immediately following the requirements, a number of Active Record error and exception
classes are defined. We covered the details of these exceptions in Chapter 6, so we won??™t go
into them again here. The most important thing to note about this section of the code is that
all the Active Record errors inherit from Ruby??™s standard StandardError class, which itself
inherits from the Exception class.
Past the exception definitions, we find the Rdoc documentation that briefly outlines the
details of the ActiveRecord class. This information provides the base for the official Active Record
documentation and for much of this book. Of course, most things are only briefly explained in
the Rdoc (or there would be no need for this book). Still, reading through the documentation
there is always a good idea.
