title: What is the canonical Rails way to collect & store physical or mailing addresses?
body: <p>I need to collect and store mailing addresses in a Rails (2.3) app. Is there a Rails way to do mailing addresses? For example, I would do <code>f.date_select</code> to generate a series of dropdowns to handle dates, which are then stored in the database, which I defined in schema and migrations as <code>t.datetime "foo"</code>.  I would consider that the canonical Rails way to handle dates, and am curious if there is an analogue for physical addresses, postal codes, etc.</p>
