[pyxser-users] problem serializing built-in and other types

[Vardan A. <vak...@gm...>]

Hi Daniel,

It looks like pyxser has a problem serializing built-in types when
they are at the top level. For example each of the following will
throw a "ValueError: Argument given for serialization/deserialization
is not a Python Object or is None.":

pyxser.serialize(obj = 1, enc = 'utf-8')
pyxser.serialize(obj = 'foo', enc = 'utf-8')
pyxser.serialize(obj = ['foo'], enc = 'utf-8')
pyxser.serialize(obj = ('foo'), enc = 'utf-8')
pyxser.serialize(obj = {1:'foo'}, enc = 'utf-8')

Also, an empty class also has the same problem:
class Test: pass
pyxser.serialize(obj = Test(), enc = 'utf-8')

But if I do
x = Test()
x.foo = 'foo'
pyxser.serialize(obj = x, enc = 'utf-8')

then it works fine.

Is this by design, or am I using it wrongly?
I encountered this when I was trying to serialize the result of
User.all() that gets all the users through sqlalchemy.

Thanks.
