You may want to look at get_value_for_datastore here:
http://code.google.com/appengine/articles/extending_models.html
This gets called in the course of a put, and can be used to accomplish
other actions as well.

If you want to add something to __init__, you can do something like
this:
class A(BaseModel):
def __init__(self, *args, **kwargs):
# do something here, e.g. adding values to kwargs (property
values)
kwargs[canonical_name] = kwargs[name].lower().strip()
super(A, self).__init__(*args, **kwargs)

Hi all,
I want to overwrite the default save method of the
google.appengine.ext.db.Model so as to perform some special work each
time the entity save(or update),I know in Django model this should be
like this:(in the model definition)
def save(self, force_insert=False, force_update=False):
self.level = self.level+1 #I want to let the level property
auto add
super(User, self).save(force_insert, force_update) # Call the
real save() method.
#do_something_else()
But, this doesn't work with google.appengine.ext.db.Model,it comes out
that the Model's put method takes exactly 1 argument,so I omit
them,like this:
super(User, self).save(),
Is that right?
I was wondering how to construct a Model,as there's a init method:
def __init__(self, parent=None, key_name=None, _app=None,
_from_entity=False, **kwds)
It seems super(User, self) is not right here
Anyone could help ?
