Hi All
I''m trying to combine the from_for and select helpers
Right now I have
form_for :service, :url => ...... do |f|
select("abc", "xyz_id", @my_arr.collect {|item| [ item,
"bla" ] },
{:prompt => "opt1"} )
....
end
What I want to do is something like
....
f.select("abc", "xyz_id", @my_arr.collect {|item| [ item,
"bla" ] },
{:prompt => "opt1"} )
....
(this doesn''t work)
I''ve tried many things but I cannot get this to work, any suggestions ?
thnx a lot
LuCa

What do you want the user to see in the drop-down? What do you want
stored in the xyz_id field of your @xyz object? I''m having a hard time
understanding the .collect call in there.
Does this run without error?
f.select("xyz_id", @my_arr, {:prompt => "opt1"})
Cheers,
-Roy

I''m using rails 2.0.2
In the view(haml):
- form_for :xyz, :url => my_url(params[:my_id],@vals), :html => {:method
=> ''put'', :multipart => true} do |f|
f.select("xyz_id", @my_arr.collect {|item| [ item, "bla" ]
},
end
The ERROR:
undefined method `merge'' for [["A", "bla"],
["B", "bla"], ["C",
"bla"]]:Array

And in the controller/action I have
@my_arr = %w(A B C)
Hopefully it makes it makes sense

The problem occured due to the first 2 parameters. For example, this doesn''t work select("abc", "abc_id" .....) but this does select("abc", "def_id" .... ) so now it works for f.select too! thnx a lot for the help!! -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
