Scaffolding, DRY and RHTML
Hello all, I''m working on a couple of Rails projects at the moment and
have noticed something that seems to go against the DRY principal.
Why, when scaffolding, are individual CRUD rhtml files created instead
of using one as a partial and having the others use that single
partial? This especially applies to the list rhtml. I am about to get
to the other operations and see how feasible

Can the has_many create() method return an ID?
Hi all,
I have a has_many relationship, Cookbook :has_many Recipes
If I want to create a new recipe in my cookbook I do:
cookbook.recipes.create(data)
It would be nice if I could then easily get the id of the new recipe,
but the create() method doesn''t seem to return anything. Any ideas how?
Thanks in advance!

easy scaffold question(s)
I''m doing very well with the Hibbs Rolling on Rails tutorial. I have an

Scaffolding to use has_many and belongs_to ?
What does everyone on this list think about enhancing scaffolding
somehow so that a "has_many" relationship will automatically drop the
<select> box into the view to reference the "belongs_to" part of the
view?
I think scaffolding is great but I am always adding the <select> boxes
to reference the parent association. Do you think this would be
useful? just a

Scaffolding support for many-to-many editing (habtm)?
Like with simple table editing, there are also typical ways of how a
user usually interacts with one-to-many or many-to-many relations. For
example, one would show the fields of one row of table1 in the screen
and below a line-by-line view of all associated entries in table2. Then,
one could press an "Edit" button and add or delete rows from table2 to
this entry of table1,

newbie scaffold question
I''ve got a database with several tables. I''d like to create scaffolding
for separate CRUD interfaces for several of these tables. I''m hoping
that the scaffold generator can create the CRUD code for all these
tables in ONE controller, but I don''t know how to tell it to do that, if
it can.
Can anyone verify if this is possible?
Thanks,

How to customize the default scaffold?
I know the scaffold generator is really only useful for beginners
and/or very the preliminary state of a project, but I find that I use
it a lot (especially, since I am still a beginner). There are a
couple of things I find myself tweaking (or wanting to tweak, but
never getting around to tweaking) each time I generate a new scaffold:
1) Change the layout from blah.html.erb to
