Rails - Jan 2006 - new objects and new associations in same view

Hello All,

I generated scaffolding for my Users table and setup my additional 
models with their associations. I want to be able to create a new user, 
and its associated groups and privileges from the same view.  My 
relationships are as follows:

users:
   has_and_belongs_to_many :groups
   has_many :privileges

groups:
   has_and_belongs_to_many :users

privileges:
   belongs_to :user

Right now, my controller is still the vanilla scaffolding-generated 
controller.  How can I update the view and controller to save these 
additional fields?

Yes, I have read the wikie article "How To Update Multiple Associated 
Form Elements On One Page"
(http://wiki.rubyonrails.com/rails/pages/HowToUpdateMultipleAssociatedFormElementsOnOnePage),
however, I am still a bit confused.  The primary object (employee) in 
this article also seems to have already been created.  I want to do it 
(create user object and assocations) all in one shot.  Any enlightening 
thoughts/comments would be appreciated.

For groups:

http://wiki.rubyonrails.com/rails/pages/CheckboxHABTM

And you could do something like:

<%= collection_select ''user'',
''privilege_id'', @privileges, ''id'',
''name''
%>

for the privileges. Put this in your _form.rhtml, and set @privileges to 
Privilege.find_all in your controller. Change the last parameter 
(''name'') to a column of privilege:

@privilege = Privilege.find(1)
@privilege.name # this method will be used if you use ''name''
as the last
parameter

Jules,

Thanks for the help with the groups.  I think my privileges table is a 
bit more complicated.  The values are a combination of a port and ip 
address.  Since these can be made arbitrary, I have created a 
one-to-many relationship between the users (one) and privileges (many) 
table.

In the view, I plan to have two text fields, one for port, and one for 
ip.  You can click on a button, and it will store this in a select box 
or create a new set of textfields so that more than one privilege can be 
granted at a time.

Any suggestions on how to accomplish this?

Thanks.
