"has_many :through" because "push_with_attributes" is deprecated

I want to use "has_many :through" in line 78 because "push_with_attributes" is deprecated.

How would I go about this, please? I want to create, really, an instance of the Membership class.

code can be browsed in the "trunk" by clicking on: http://strawr.googlecode.com/svn/trunk/

It may have changed since I posted:
