Thanks for the tip, Manasi. This didn't solve the problem. After
defining them as you suggest I do the following:
user = User.new
user.save!
membership = user.memberships.create
role = membership.create_role
And then in the debugger:
(rdb:1) user
#<User id: 1, created_at: "2009-05-20 17:34:08", updated_at:
"2009-05-20 17:34:0
8">
(rdb:1) user.memberships.find(:first)
#<Membership id: 996332878, user_id: 1, role_id: nil, created_at:
"2009-05-20 17
:34:08", updated_at: "2009-05-20 17:34:08">
(rdb:1) membership
#<Membership id: 996332878, user_id: 1, role_id: 1, created_at:
"2009-05-20 17:3
4:08", updated_at: "2009-05-20 17:34:08">
(rdb:1) membership.role
#<Role id: 1, created_at: "2009-05-20 17:34:08", updated_at:
"2009-05-20 17:34:0
8">
(rdb:1) user.role
nil
Now the interesting thing is that user.memberships.find(:first) has no
role_id, but membership does. I'm not sure what this means, but I'll
explore it further. I suspect my problem might be cached records,
but:
(rdb:1) user.memberships(true).find(:first)
#<Membership id: 996332878, user_id: 1, role_id: nil, created_at:
"2009-05-20 17
:34:08", updated_at: "2009-05-20 17:34:08">
I thought the 'true' caused this to be reloaded, so I don't have an
explanation for the discrepency.
I'm a little relieved this didn't work, since the combination of
has_many memberships and has_one role doesn't make sense to me.
