I think you will be adding both an index and the text displayed. I still really dont understand why you dont want to do it the other way, again maybe I dont understand youir final outcome -- but as far as I can understand the functionally on your page the result would be about the same, but this is what I would do if I needed to. Also note, that in my opinion you are beginning to fight Rails but trying to go outside and do something manually.... in my experience I have always fared better by using conventions and existing functionality whenever possible, as I have found that when I do not, I end up coming upon special cases I did not think of and end up investing a lot more time (and usually end up going back and doing it the Rails way). > 2) Once i have a listbox with the new values how can i loop though the > values and submit each one to the db as a new value ? > You can request the params from the page in your controller. So for example I think you could do something like (there are more concise ways and you will probably have to play around with it go get it to work -- just turn on the debugger): params[:itms].each do |itm| item = Item.new item.name = itm[:name] item.save end > > Thanks. :) > > -- > Posted via http://www.ruby-forum.com/. > > -- > You received this message because you are subscribed to the Google Groups > "Ruby on Rails: Talk" group. > To post to this group, send email to [email protected]. > To unsubscribe from this group, send email to > [email protected]<rubyonrails-talk%[email protected]> > . > For more options, visit this group at > http://groups.google.com/group/rubyonrails-talk?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
