Wouldn't it be great (tm) if we could add an "on_delete" and
"on_update" config
to all the relationships? Like the "cascade_delete" config option.
If the DMBS supports that type of actions DBIC does not have to take
care of it,
otherwise it does.
There might be a good reason why this has not been done :-)

Hi,
I use the ON DELETE statements in my Pg database to set the foreign
key to null if a column is deleted.
But this information doesn't make it's way to the schema if I use
Schema::Loader. And therefore the files created by create_ddl_dir are
useless because they don't contain this information either.
I'd like to write a patch but I have no clue where to put this kind
of
code!
First, figure out what syntax you'd need in your files to make
create_ddl_dir
work. (frankly, using Schema::Loader -and- create_ddl_dir is silly -
pick one
place to be primary and stick with it).
You may need to check SQL::Translator::Producer::PostgreSQL to
figure out
whether it's supported.
If it isn't, that's the first thing to patch. If not, proceed to
stage 2.
Stage 2, write a failing test for DBIx::Class::Schema::Loader and then
patch that to figure out the ON DELETE info when it loads a pg schema.
