I have a model, Download, with a HABTM relationship to another model,
Product. In the index view for Download, I want to list all of the
associated products by name. Here is my view code for the table row:
<script src="http://gist.github.com/73492.js"></script>
I''ve tried using "download.products.join('',
'')", but all I get is the
objects has mark (#) in my HTML. Is there a quick and easy way of
creating a joined list of all the product names that I just don''t know
about?
Thanks.

It''s up to you to turn that array of products into an array of suitable strings (checkout the select/map methods on Array) and then call join on that Fred> > Thanks.--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
