google-app-engine,go , Datastore object Key field


Datastore object Key field

Question:

Tag: google-app-engine,go

Does the GAE datastore API (Go) support returning the key on an object by default?

Currently I'm solving this by updating an ignored Key field manually in code after writes and fetches like this:

type User struct {
  Key    *datastore.Key `datastore:"-"`
  Email  string
  ...
}

Do I have to do this or is there a way that makes that redundant?


Answer:

You have to maintain that field yourself. You can write a function using reflection which can perform that work on any struct, but there is no method in the appengine SDK to do what you want.
