Once you do
model2.put()
the exception will be raised as expected. There is no validation prior to
attempting to store the data in datastore unless you'd like to manually
create it.
I.e. to get the error you were looking for try the following code:
class SecondModel(ndb.Model):
important_prop = ndb.StringProperty(required=True)
class FirstModel(ndb.Model):
some_prop = ndb.StringProperty()
some_other_prop = ndb.StructuredProperty(SecondModel, required=True)
def some_func():
buggy = None # attention here
model2 = SecondModel(important_prop=buggy)
*model2**.put()*
model1 = FirstModel(some_other_prop=model2)
model1.put()
return
The highlighter line is all that was added.
Thanks,
Mihail.
