Rails - May 2005 - Alter code generation?

Is there any support for "overriding" the generated scripts?  In one
case, I''d
like to generate an additional file, in one case, I''d like to put a
generated
file in a different location, and in one case, I''d like to actually
affect
the content of the generated code.

Sure, adapt one of the builtin generators to your needs.  Copy the  
files from the gem directory or from a svn checkout to ~/.rails/ 
generators.  For example:
   cd /path/to/svn/checkout
   cp -r railties/lib/rails_generator/generators/components/model  
~/.rails/generators/mymodel
Then alter your new mymodel generator as you like.  Run it using
   ./script/generate mymodel Foo
just as you would with the builtin generators.

The generate script looks for builtins, gems ending in _generator,  
user creations living in ~/.rails/generators, and application- 
specific generators in RAILS_ROOT/scripts/generators.  It searches  
these sources from app -> user -> gem -> builtin, so you can even  
create a generator with the same name as a builtin to override it.

This is a great way quickly roll code in your own style.  Modifying  
the scaffold generator is particularly rewarding..
