Hello
I am trying to get an event handler to fire each time I insert a record into my DeviceData table. I try delete the previous record which matches the recordType and device_id field being passed in. However when this runs it deletes random records until eventually no more records are left. What am I doing wrong???
Backendless.ServerCode.Persistence.beforeCreate(‘DeviceData’, function(req, res) {
console.log(“recordType = '” + req.item.recordType + “’ AND device_id = '” + req.item.device_id + “’”);
// Initialize Class
var deviceData = Backendless.Data.of(‘DeviceData’);
deviceData.bulkDelete(“recordType = '” + req.item.recordType + “’ AND device_id = '” + req.item.device_id + “’”);
// Find Records
Backendless.Data.of(‘DeviceData’).find().then( function( objectArray ) {
console.log(objectArray);
})
.catch( function( error ) {
console.log(error);
});
}, true);
