google app engine - GCP Datastore after migration: Key must be from same project as batch -


i tried backup google cloud datastore , restore project, according guide. worked fine, except put or delete node in new project, gives:

valueerror: key must same project batch

so, checked source , found this:

if self.project != entity.key.project:     raise valueerror("key must same project batch")

so seems items in datastore include previous project in keys. there way fix this?

'hasOwnProperty' in javascript -

i use obj.hasownproperty judge whether object has property, when replaced obj[prop] !== undefined , not normal implementation, ask, why behind method can not use it? object.hasownproperty(prop); object[prop] !== undefined; obj[prop] !== undefined wrong 2 reasons: you can explicitly set property undefined , obj[prop] = undefined; . obj.hasownproperty(prop) return true in case. obj[prop] follow prototype chain, return property that's inherited. obj.hasownproperty(prop) returns true if property exists directly in object, returns false inherited properties.
