I try to get the values from a multiple select without luck. This is my
select:
<%= select "product", "items", @options, {}, { :multiple
=> true } %>
If I add it directly to a column in the db I get:
---
- !binary |
xGdn
What should I do with this?

Is this in a form_for? if not you should use select_tag
http://apidock.com/rails/ActionView/Helpers/FormTagHelper/select_tag
What do you have in @options?
This is the select method
select(object, method, choices, options = {}, html_options = {})
Examples here

To debug these issues you should have a look at the compiled source
with view source in the browser and see what you got.

But I only get the first value. Even if I use "items[]". -- Posted via http://www.ruby-forum.com/.

I got --- - - !binary | xGdn This tells me that it also worked with "select". -- Posted via http://www.ruby-forum.com/.

Look at the html source: does the name of the select tag end with [] ? Fred
