Hello!
I am using the standard (scaffolded), REST routing. I need to pass
external values to my "new" action for a certain model, and let the
user complete the other fields in the standard form_for.
My initial idea has been to simply amend the URL like this:
.../foos/new?size=4&weight=2
Then in the controller I just do something like:
def new
@temp = Foo.new
@temp.size = params[:size]
...
respond_to do |format|
format.html
format.xml { render :xml => @temp }
end
end
Thing is my form_for parameters are not picked up. Only the ones I
have setup manually in the URL (size and weight in my example) are
taken into account.
I believe it is due to the fact that they are serialized and added to
the end of the URL, whereas it already contains a "?" and some
parameters so they end up being ignored.
Do you know how to do this?
Thanks!
PJ

Thanks Hassan. Sorry I did not give the context: these links are used by another, external app (say app B). A user of app B can trigger the creation of a record in App A, and it needs to pass some default parameters. So I don''t believe I can use the standard method of using hidden fields, can I? So the idea really is: how can you create entry points to an app where these entry points contain default parameters for the creation of a record? It seems to me these parameters HAVE to be passed with the URL, but maybe I am wrong? Thanks!

If so, there''s no reason you couldn''t conditionally add hidden inputs to your `new` form to be processed as part of the `create`. Please let me know if I''m totally off base on my understanding :-) -- Hassan Schroeder ------------------------ hassan.schroeder-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org http://about.me/hassanschroeder twitter: @hassan -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Your understanding is absolutely right. My initial gut was indeed to try hidden inputs. But it does not work: App B calls appA/foos/new?size=4&weight=2 App A foo/new method is called and the form is pre-populated with size and weight. The problem is, the URL is still appA/foos/new?size=4&weight=2. When the form is submitted, I think what happens is Rails tries to append the form parameters to the existing URL. Since that URL already contains parameters it does something like: appA/foos/new?size=4&weight=2?size=4&weight=2&price=10 etc and the second set of parameters after the second "?" is ignored by the browser. At least that''s my understanding (I could be wrong). I guess it would work if I could remove the first set of params. But it looks like I will need to do a redirect_to. I was thinking there might be a cleaner way. Sorry it is a bit convoluted... Thanks!

What is your view code for the start of the form, and what does using `view source` show you for that? -- Hassan Schroeder ------------------------ hassan.schroeder-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org http://about.me/hassanschroeder twitter: @hassan -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Hassan,> Sorry, that makes no sense -- the submission URL (that will go to the > `create` action) shouldn''t contain anything from the `new` request.You are absolutely right... I got totally confused. I looked at my form again and indeed the problem was in it. Thanks a lot for pointing me in the right direction.
