Christophe,
I mistyped my JSON:
var group_with_admin = {"attributes" : {"name" : "Group 1"}, "users" :
[{"attributes" : { "first" : "John"}}]};
users is an array. So I tried this:
var groupTemplate = new Template('#{attributes.name} is administered
by #{users[0].attributes.first}');
Thanks to your fix, #{attributes.name} renders "Group 1", but I can't
get to "John". My active record object is the result of this finder:
Group.find(:first, :include => :users)
where groups have many users.
I presume this isn't such a straight-forward fix. Any pointers? This
is the first time I've actually looked at the source code for
prototype - shame on me!
Regards
Adam
