I have many pages to generate quickly. They are based off of the  
scaffold  
generator, but I want to convert the rhtml files to Markaby, and change  
some  
formatting. Without having to do a lot of repetitive hand editing. Is  
there  
a simple way to overwrite/extend part of the scaffold generator? Do I  
need  
to write my own from scratch?

I’m not quite sure about what you need here and not sure what Markaby is  
but if it’s on a linux box and all you need is to rename the files  
(don’t know if you can change the contents of the file) from .rhtml to  
.mab, a Linux command on renaming is:

mv \*.rhtml \*.mab

And all of your files will be get renamed to the following extension.

hope that was helpful

Thanks for the reply. What I was trying to say was that I needed to  
re-write parts of the default scaffold generated code. For instance,  
adding  
css class names to the labels on the forms. Converting the default  
\_form.rhtml to a more CSS friendly fieldset layout. Overwrite was a  
bad  
choice of words. I think the OO term is ‘overloading’. Where you change  
the  
behavior of a method by creating a new one with the same name.

Is it possible to override the scaffold output for the ‘\_form.rhtml’  
file?

if not, should I be looking at creatin a generator or a plugin to  
build my  
own custom replacement?

I think that’s a real good question, because in the default rendering  
are alway things missing … and sometime real basic stuff. I tried out  
ruby-on-rails and wondered that the date an time formats are shown nice  
with lists, but enumeration an sets not. A enumeration in mysql should  
generate radio-button or a list, a set check-boxes for example and not a  
plain input field.

For me is the question …

1. where can submit some kind of feature requests and
2. how could I overload (=adding features, not rewrite all by myself)  
the default scaffolding.
