What steps will reproduce the problem?
1. Create a user model that will fail when put() is called on it. E.g.:
class CustomUser(webapp2_extras.appengine.auth.models.User):
has_error = ndb.StringProperty(default=False)
2. call
ok, user = CustomUser.create_user('some_fake_auth_id')
3. the line "user.put()" in create_user
http://webapp-improved.appspot.com/_modules/webapp2_extras/appengine/auth/models
.html#User.create_user
will fail.
4. The Unique datastore will hold an entry for CustomUser with
'some_fake_auth_id', but CustomUser will be empty, because user creation failed.
What version of the product are you using? On what operating system?
App Engine / Python
- name: webapp2
version: "2.5.1"
Please provide any additional information below.
Though this example the error is clearly on the programmer's side in providing
a model that won't allow for it to be saved, there are other sources of errors
(DeadLineExceededError e.g.) that will cause user.put() to fail. I think in
that case, webapp2 should handle this scenario gracefully and rollback the
changes it made to the Unique datastore.
