Activerecord-association: create new object (find class)

Question

I have an model with a relation, and I want to instantiate a new object of the relations type.

Example: A person has a company, and I have a person-obje

Answer 1

You can also use build_association() in the relationship classes.
Simplest way to use it is through the Model's __call, i.e. if your relation is something like $person->company, then you could instantiate the company with
$company = $person->build_company()

Note that this will NOT also make the "connection" between your objects ($person->company will not be set).
Alternatively, instead of build_company(), you can use create_company(), which will save a new record and link it to $person
