Hi all,
I have a question about a MVC-"problem" and how to handle so a case.
I want page which lists some users. You can add users with a
dropdown-list.
So something like:
---------------------
%h2 Selected users
user1
user2
%h2 Add an extra user
user3
user4
user5
I now have:
------------------
%h2 Selected users
user1
user2
%h2 Add an extra user
user3
user4
user5
What is a nice/clean way to remove the selected users from the
dropdown-list?
I now have this ruby-code in my rhtml:
collection_select(''new_declaration_payer'',
''user_id'', @users, ''id'',
''fullname'', {:prompt => ''-- Selecteer een betaler
--''}
Thanks in advance!

It sounds more like a Rails, possibly even a JavaScript issue.> I want page which lists some users.

Care to elaborate?> What is a nice/clean way to remove the selected users from the > dropdown-list?If all you want to do is remove users from your list, the best place to do so would be in your controller. I see you have a @users object. Try something like... @users = @users.map { |user| user.meets_some_condition } If instead you want to dynamically add/remove users from a drop-drop list, you''re going to need JavaScript. I''d suggest jQuery. Hope that helps. - Rabbit -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
