OK, so I get that ActiveRecord determines model attributes through
reflection of the table schema. Handy for many cases, but not mine.
I need to override that and provide my own mapping of attribute names
to column names to use the mapped names throughout the application code.
I’ve been poking around looking for where in AR’s hierarchy I can can
inject this mapping, but so far I’m coming up empty.
I’ve written/been using my own framework for years in another
language that handled all this (more of a table gateway than an
ActiveRecord pattern), so I can do it, just wondering if Rails has
it, and if not, what’s the best, i.e. Ruby/Rails “right way” to add
it (extend AR modules? write a super class between AR and all my
models? Write a utility class for all my models to use, other?)
For those of you that want to know why, the reaons boil down to
adapting to legacy data (same “News module” code used over & over to
adapt to existing news data), and same code being used to aggregate
multiple data sources. IN both cases the mapper abstracts the real
data source so the attributes of the app code can remain a familiar
(yes I posted this a couple days ago, but it was a weekend, thought I
might have more luck on a weekday
