问题 I'm in a bit of pickle, I received a request to create CRUD app to edit JSON object in an array and upload them. I did a bit of research and came across http://www.taffydb.com/ but it doesn't really fit my requirements. EDIT: I also came across jtables, but it use mysql, similar to http://www.jeasyui.com/tutorial/app/crud.php but it also uses mysql. Is it possible to skip the database portion and write directly to the JSON file? As this is a very small JSON file, having a database would seem

问题 I have been unable to save a record to a SQL Server database when removing a foreign key value from the record.

问题 I am trying to add file upload (filestore) to an existing CRUD page. The examples I've found are all rather dated, and apparently filestore has changed enough where most of what you'll find is obsolete. I did locate this tutorial video, which shows step-by-step how to implement filestore in sufficient detail that a relative novice (me!) was successful.
