Hi Chris,
Now that Alexandro brings this up again, I have managed to add the
ability to truly render a partial inside a tag, model or anywhere else
you'd need to do it. It is, however, part of an extension with loads
of other stuff in it, and it requires some ugly hacks. Amongst other
things, Radiant has to be hacked to set the active controller, request
and response on tags.globals, so they are available to initialize an
ActiveView::Base instance to render a partial inside the tag.
If you are interested, I could provide the required code for in a
pastie, but you might want to stick with Alexandros solution which
seems less hacky, albeit not bullet proof. (How do you for instance
pass data to the partial with this approach?)
Cheers,
Casper Fabricius
