'target' in transition may be callable

[belegnar]

it is useful when FSMKeyField is in use
also, using instance.setattr instead of instace.dict in FSMKeyField().set_state()

[kmmbvnr]

It should be in meta.next_state function, elsewhere signal data and set_proxy calls gots wrong state

Also please add separate test case file with all proxy state tests and non fk fields tests.

Readme also need to be updated.

Also please check graph_transition command.

And test should works (yep with python 2.6 and django 1.6 support)

Target states could be any State object

    @transition(
        field=state,
        source='for_moderators',
        target=GET_STATE(
            lambda self, allowed: 'published' if allowed else 'rejected',
            states=['published', 'rejected']
        )
    )
    def moderate(self, allowed):
        pass
