Kendo UI MVC Grid始终尝试保存2条记录

Question

I have configured this grid to autoSync, so that you can edit it and every time you change a field, it will submit the Update action. For this to work, you have to set the Batch(true) property, which supports editing multiple rows, but that is not how I am using it as the autosync automatically fires the update event, you don't get an opportunity to edit multiple rows before calling update.

For some reason, it is always submitting a new record Update. For example, when I click the Add New toolbar button toolbar.Create().Text("Add New Time Task"); ), you can see in the Chrome dev tools network tab that 2 records are being submitted to my controller...a model[0] and model 1 in a single update call.

But if I perform an InCell edit, and leave focus of the cell to trigger the update call...2 separate update calls are being made...the first one is an Add New (I can tell because the Id = 0 and all the defaults are as per my grid configuration).

Anyone know why this Add New type call is being triggered?

Picture of double call to Update upon editing a single cell:

Answer 1

Well that was a fun 6 hours figuring this out. It turns out that on our test database, someone turned off the Identity default specification on the Id primary key column. Then during testing, a test record with an Id = 0 was saved, so that was being into the grid every time, then when you'd save or update another row, that row with the Id = 0 was also in that batch trying to be saved.
