validation - Intersystems Cache ObjectScript change property value during %Save() -


given:

  • a class named b.
  • 2 persistent records of class b, id = {"b1", "b2"}.

  • a class named a:

    class extends %persistent {  property rb b;  foreignkey fkb(rb) references b(); }

  • an instance of class a, named obja, obja.rb = "b3" (which invalid value because b has no "b3" persistent record)

i want that:

when obja going saved (obja.%save()), substitute empty string rb invalid value , save it.

so far:

i have tried make substitution using callback methods ( %onbeforesave), seems %validateobject being called before.

is there way of doing value changes before %validateobject using callback methods?

thanks in advance.

you can modify objects in callback method %onaddtosaveset: http://docs.intersystems.com/cache201511/csp/docbook/docbook.ui.page.cls?key=gobj_callbacks#gobj_cb_onaddtosaveset

i have model ( article ) field (the name type ) of type enum('source', 'translated') , return 1 article ordered type field. source articles should returned before translated articles. like: article.findone(order: [ { type: [ 'source', 'translated' ] } ]); unfortunately there appears no built-in solution sorting enums. instead have sort by case , couldn't find documentation on how sequelize. what conventional approach here? sorting case hard in sequelize, sort field (the second answer in linked post) should possible: order: sequelize.fn('field', sequelize.col('type'), 'source', 'translated') it's supported mysql far know though
