That's perfect when have not > 3k tables and dont need load compound

sure that works too, the docstring now says "any callable" so sure

Here is my example, how to get arond decorator classmethod (without it not
work, self.__class__ instead of Address not override this function)

it's an alternate constructor that accepts a, b, c, d as arguments,
rather than name, value, towndetail.
it's @classmethod because there is no instance of Address when it is called.
it's

Thanks, Not so bad as expected) Can you add this example to official docs?

composites of composites aren't supported directly so you'd have to
map out all the columns for "street" directly, then define a
constructor that handles the columns:
class Address(object):
def __init__(self, name, value, towndetail):
self.name = name
self.value = value
Can someone have example of this?
Example is
class TownDetail(object):
def __init__(self, name, value):
self.name = name
self.value = value
def __composite_values__(self):
return self.name, self.value
def __eq__(self, other):
return isinstance(other, self.__class__) and\
13 matches
