I use python in GAP and try to delete one entries in datastore by using db.delete(model_obj). I suppose this operation is undertaken synchronously, since the document tell the difference between delete() and delete_async(), but when I read the source code in the db, the delete method just simply call the delete_async, which is not match what the document says :(
So is there any one to do delete in synchronous flow? Here is the source code in db:
def delete_async(models, **kwargs):
"""Asynchronous version of delete one or more Model instances.
Identical to db.delete() except returns an asynchronous object. Call
get_result() on the return value to block on the call.
"""
if isinstance(models, (basestring, Model, Key)):
models = [models]
else:
try:
models = iter(models)
except TypeError:
models = [models]
keys = [_coerce_to_key(v) for v in models]
return datastore.DeleteAsync(keys, **kwargs)
def delete(models, **kwargs):
"""Delete one or more Model instances.
"""
delete_async(models, **kwargs).get_result()
EDIT: From a comment, this is the original misbehaving code:
def tearDown(self):
print self.account
db.delete(self.device)
db.delete(self.account)
print Account.get_by_email(self.email, case_sensitive=False)
The result for two print statement is <Account object at 0x10d1827d0> <Account object at 0x10d1825d0>. Even two memory addresses are different but they point to the same object. If I put some latency after the delete like for loop, the object fetched is None.
