ok, I see.  The env keyword can be a dictionary.  So you can type out
every model class, like:

env={'User': models.User, 'Other': other_models.Other, ...}

but if that's not feasible then you'll have to make a proxy that acts
like a dictionary.  Something like this should work:

class MultiModuleEnv(object):

    def __init__(self, modules):
        self.modules = modules

    def __getitem__(self, name):
        for m in self.modules:
            if hasattr(m, name):
                return getattr(m, name)
        raise KeyError("%s not found in %r" % (name, self.modules))

datafixture = GoogleDatastoreFixture(env=MultiModuleEnv([models,
other_models, more_models]), ...)
