Hi,
I implementing a "on_field_change" hook. External classes can hook
the DBIC model to observe (usually) status changes and start some
business logic processes. The reason I choose this approach is that
it creates a loosely coupled system, where I can add other
components later without going back and modifying old code.
From my first look through the code, I think the set_column() is
the proper place to do this. But we could set_column() and then not
update().
So update() and look at the dirty columns is probably safer.
If I want to trigger on insert also, I also have to watch for insert
().
Another option is to create an InflateColumn::Trigger and use that,
but it might not be what people expect.
Before I start coding, has anybody done this before? Suggestions?
Did you look at DBIx::Class::CDBICompat::Triggers?
