Called before an instance is created, with the class as the sender. Called with the arguments (instance, kwargs, post_funcs). There may be a connection argument. kwargs``may be usefully modified.  ``post_funcs is a list of callbacks, intended to have functions appended to it, and are called with the arguments (new_instance).

Note: this is not called when an instance is created from an existing database row.


f __sizeof__(...) ...

__sizeof__() -> int size of object in memory, in bytes

f __format__(...) ...

default object formatter

f __subclasshook__(...) ...

Abstract classes can override this to customize issubclass().

This is invoked early on by abc.ABCMeta.__subclasscheck__(). It should return True, False or NotImplemented. If it returns NotImplemented, the normal algorithm is used. Otherwise, it overrides the normal algorithm (and the outcome is cached).

f __init__(...) ...

x.__init__(...) initializes x; see help(type(x)) for signature
