What am I doing wrong here? I''m trying to create a select box with a
normal id/value setup.
Here''s my code:
<% form_tag ''/list'' %>
<%= collection_select( :route_id, @routes, :id, :name, {}, {} ) %>
<%= end_form_tag %>
Here''s the NoMethodError exception I''m getting:
undefined method `inject'' for :id:Symbol
Extracted source (around line #15):
12:
13: <% form_tag ''/list'' %>
14:
15: <%= collection_select( :route_id, @routes, :id, :name, {}, {} )
%>
16:
17: <%= end_form_tag %>
18:
What am I doing wrong?
Thanks!

<%= collection_select( :route_id, @routes, :id, :name, {}, {} ) %>
You may be using the wrong tag here. collection_select is for model
fields so expects:
collection_select(object, attribute, collection, value_method,
text_method)
You probably want something like this:
<%= select_tag(''route_id'',
options_from_collection_for_select(@routes, :id, :name)) %>

I''ve tried that and it does work, so I appreciate your help. How can I add an onchange event to this select box now?

Actually, I figured that out, but how can I insert a default value, like ''Please select an option...'' to the select box? -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
