Problem with relation ship using fixtures

Rails
1

Hi all,
I am having a problem with the relation ship with the fixtures.

My rails version is 2.2.2, and am using the old style of fixtures.

My models are

Class Account < ActiveRecord::Base
has_many :users
end

Class User < ActiveRecord::Base
belongs_to :account
end

My Fixtures are

#users.yml
Harish:
id: 1
name: Harish
account_id: 1
Rahul:
id: 2
name: Rahul
account_id: 1

#accounts.yml
account1:
id: 1
name: Account1

so in my model code if I have
1 user = User.find(user_id)
2 user.account.name

Then its giving NoMethodError in Line #2
when I try user.account its giving # class but
user.account.name is failing.

I also tried with the new fixtures as per Rails 2.0 still same problem.
What I might be missing?
Any thing should be loaded??
This code is working in Rails 1.2.3 previously, but now its not
working…
Can any one help with this??
