I am trying to allow the user to select more than one value from a
selection list. Here is the code:
<%= collection_select(:transition, :complete_tasks, @permissions, :id,
:path, "", {:size => "10", :multiple => true} ) %>
The multiple HTML option is supposed to allow multiple selections and,
in fact, it does, although the HTML generated show the attribute as
multiple=multiple when it should be just multiple.
The problem is that RAILS is only returning one value in
transition.complete_tasks.
Any idea what is going on?
Thanks!

I ended up having to write a small, simple helper for this because I ran into the same problem. Basically the helper takes the same attributes as options_from_col.... does, and also takes an array of selected objects and generates the list accordiningly. I dont have it on me now, but will post it tomorrow if I can and if you need it. -Nick On 1/4/06, Stan Shore <stan@workflowinc.com> wrote:> > I am trying to allow the user to select more than one value from a > selection list.

Just call your parameter something with [] on the end. That way rails knows it''s multiple. i.e if you call it blah[] then @params["blah"] yields an Array. </quote> That was in a thread with subject "[Rails] Getting multiple values from <SELECT> into @params?", back in April 2005. regards Justin
