Take this contrived example:
Department
has_many :people
end
Person
belongs_to :department, :conditions => { :name => "Development" }
end
person # assume this exists
person.department.name
=> "Development"
department # assume this exists
department.name
=> "Marketing"
person.department = department
person.save
person.reload
person.department
=> nil
SELECT * FROM "departments" WHERE ("departments"."id" = 1 AND
("departments"."name" = 'Development'))
