I have a User class, a Membership class and a join model
UserMembership. Membership has an attribute called :year.
I observe that for a User object 'u', I can do this -
u.user_memberships.first('membership.year' => '2009')
but this -
u.user_memberships.all('membership.year' => '2009')
throws an exception -
ArgumentError: Unknown property 'name'
from /home/mark/Code/merb/craw/gems/gems/dm-core-0.9.11/lib/dm-core/
query.rb:667:in `method_missing'
etc...
Any ideas why this would be? I can get around it by using 'find' with
a block, but it's a bit more complicated.
BTW I haven't actually seen the usage in the first case documented
anywhere, but I was experimenting based on an example on the wiki that
does a find like this -
Article.all('author.name' => 'Michael')
Is this approach meant to work on collections as well as models?
