ManyToMany's Related Manager is not provided on object

[edimedia]

Hi !

I think the related manager is not provided on object when this one is retrieved from DB, look at this:

models.py

db, registry = get_db_connection()

class World(Model):
    id = fields.IntegerField(primary_key=True)
    name = fields.CharField(max_length=255)

    class Meta:
        registry = registry

class Hello(Model):
    id = fields.IntegerField(primary_key=True)
    name = fields.CharField(max_length=255)
    worlds = fields.ManyToManyField(World, related_name="hellos")

    class Meta:
        registry = registry

test_many2many_create.py

world = await World.query.create(name='Hearth')
hello = await Hello.query.create(name='King')
await hello.worlds.add(world)                             # It works correctly

test_many2many_retrieve.py

h = await Hello.query.get(id=1)
w = await World.query.get(id=1)
await h.worlds.remove(w)                                   # AttributeError: 'NoneType' object has no attribute 'remove'

And when i'm looking for a sample code in edgy/tests/foreign_keys/test_many_to_many.py, i see there's no test about retrieve (get or filter method).

Thank you.

@edimedia thank you for your message. It is indeed a regression happening here since we are making our internals faster. I will have a proper look and come back to you during mid next week. Is that ok?

[edimedia]

Yes, I can wait for that, in the meantime I can do something else.

Thank you !

I make an issue from it, so I can reference it

@edimedia I think @devkral addressed this already but also in the version 0.12.0 here are great new improvements.

I just saw that, and thanks a bunch for the hard work.

Now I'll keep rolling on my work.
