in access, i'd give user datasheet form key in data. datasheet merges 2 tables together, parent ( product ) , child ( book ). i've linked them using id s , share 1-to-1 relationship. however, while entering data, long key in book data, following error message shows up: you cannot add or change record because related record required in table product. and clueless do, thought giving administrator-only metadata product table help. when set "book" , create new row in product , data macro programatically create corresponding row same id in book table. sound feasible? anyway, need retrieve id of current record of book before insertion, wonder how'd able that. make sure foreign key (=field table linked parent table) of book table included in underlying query.

we need keep our firebase data in sync other databases full-text search (in elasticsearch ) , other kinds of queries firebase doesn't support. this needs close real-time possible, can't export nightly dump of firebase json or that, aside fact rather large. my initial thought run node.js client listens child_changed , child_added , child_removed etc... events of main lists, bit unweildy , reliable way of syncing if client re-connects after period of time? my next thought maintain list of "items changed" events , write every time item created/updated, similar firebase work queue example. queue contain full path data has changed , worker consumes , updates local database accordingly. the problem here every bit of code makes updates has remember write queue otherwise 2 systems out of sync. proxy code shouldn't hard write though. has else done similar success? for search queries, can integrate directly elasticsearch; there no need sync se

in interfaces there typically ilist<isometype> represent list-type members , expect implementation supporting add method. but in interface implementation, there ilist<isometype> = new list<isometype>() and everytime use list, have cast, example (this.mylist list<imytype>).addrange(sometype.tolist()); is there better way this? how avoid cast? - edit ask more information - instead of extension method, there small linq expression solve that? ilist<string> list = new list<string>(); var items = new[] { "1", "2", "3" }; items.tolist().foreach(x => list.add(x)); but not being straight forward, inverts being done. (the action on items add, not on list). anything better that? possible can done on list? addrange not method on ilist, add is, can make extension method: public static void addrange<t>(this ilist<t> list, ienumerable<t> values) { foreach(var value in values
