LoopbackJS, Angularjs sdk, model.$save duplicates - angularjs

Question

I am using lopbackJS AngularJS sdk.I have a model for sites (id(pk) int, name varchar(50), url varchar(100)).
When i try to update name and calling site.save(), record became duplicated. If i try to update other fields except name, update succeeded.
Any suggestion?

Answer 1

I found that, 'Site' table has trigger and it prevents to update.
I removed trigger and update works...
