Rails: Transmit value into link_to

[Still trying to safely get on the Rails mailing list...]

Rubies:

The great thing about Web programming is there's so many languages to chose
from - or mix together.

Specifically, an ERb page can contain 3 languages:

<select id="myList">
<% for record in @table %>
<option value="<%= record.id %>"><%= h(record.name) %></option>
<% end %>
</select>

Okay, that's a combobox with names and values in it.

Now how do I let the user select one option, and send it to the next page
with link_to()?

<%= link_to 'Go to Next Page',
{:action => 'goToNextPage', :id => ??? }
%>

The third potential language is JavaScript, so in theory I could add an
onclick event to each <option>, or similar, then express the link_to in raw
HTML...

<a id="linkOut" href="/page/goToNextPage/2">Go to Next Page</a>

....then use the onclick event to change the href attribute.

However, that's not very Railish, and I'm sure there's some feature
available which my newbescence has overlooked!

Do you mean to say you meant this to go there? It... didn't.

Not to be mean, but... Isn't that true about all programming?
Especially with the .NET CLR and it's ability to interoperate between
languages easily. I see this as being huge eventually. (Ruby has a gem
that allows you to use .NET libraries, and of course C libraries... So
it's already walking down this path. And I'm very much looking forward
to Ruby.NET.)

I didn't say that.

I mean when I tried to register before nothing happened, and when I try to
register today I get this:

http://lists.rubyonrails.org/mailman/subsc...

blah blah blah

IOError: [Errno 28] No space left on device

I'm tormented with the urge to blame Python, but the problem is apparently
the drive filled up with mail!

The Rails mailing list is no longer there. It's a Google Group, now.
