belongs_to should be on the side of a one-to-one association that
contains the foreign key (same as a one-to-many).

The other side (the side without a foreign key should use has_one NOT
belongs to.

User
has_one :account

Account
belongs_to :owner, :class_name => 'User', :foreign_key => 'user_id'

Or you could use the standard conventions:

Account
belongs_to :user
