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/HowToUpdat...), 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. Dan

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.
