Could the MercadoPagoService class be customizable through settings.py ?

I need to personalize some of this..

I'm happy to discuss any changes/features that you might need, but you've given me absolutely NO information about what you're trying to do.

This issue is related to a capability for create a MercadoPago Marketplace, in my case.

First of all, I need to use another token (obtained from a link to my account with the account of a third party).

The most practical, it would be to be able to use a custom class, set from the settings.py, as most libraries do.

Alternatively,
I show you my solution, an inject-wrapper:

def apply_monkeypatch_to_mp_account(mp_account):
    def get_service(self):
        service = MP(self.third_party_related_account.mp_access_token)
        service.sandbox_mode(self.sandbox)
        return service
    setattr(mp_account.__class__, 'service', property(get_service))
    return mp_account

But.. I still can't size the amount of possibilities that would open just by admitting this configuration.

Including it in settings is problematic since it would override all accounts in all environments (so payments made to any account would all go to the same one).

I've been looking at the docs, and it seems the simplest clean approach would be to:

• Include an is_marketplace flag in Account.

• Include a redirect_url field in Account.

• Include a marketplace field in Account, to link subaccounts to a parent marketplace.

• For accounts that have a parent marketplace, add logic to fetch the code using the MP flow.

• Add an endpoint to receive the code at the end of the flow, and exchange it for access tokens.

• Access tokens need to be store in the DB, since they can't be re-fetched. It might also make sense to save token for normal accounts too, since right now we fetch them way too often and could throttle down on this.

I'll start fiddling with some bits of this. Does the general idea make sense to you? Do you see any problems with it, or me missing anything?

Then it would be necessary to implement the task for the token refresh, which expires every 6 months.
If it serves you as data, I am currently saving all this:

class MyAccount(models.Model):
    mp_account = models.OneToOneField(
        django_mercadopago.models.Account,
        on_delete=models.CASCADE,
        related_name='wallet_account',
        blank=True,
        null=True,
    )
    mp_public_key = models.CharField(
        verbose_name='Clave pública',
        help_text='La "Public key" dada por Mercado Pago',
        max_length=255,
        blank=True,
        null=True,
    )
    owner = models.ForeignKey(
        User,
        help_text='A quién le corresponde esta cuenta de Mercado Pago',
        related_name='accounts',
        on_delete=models.CASCADE,
        blank=True,
        null=True,
    )
    mp_user_id = models.IntegerField(
        verbose_name='Mercado Pago user_id',
        blank=True,
        null=True,
    )
    mp_access_token = models.CharField(
        verbose_name='Token de acceso',
        help_text='Token de acceso para marketplace',
        max_length=255,
        blank=True,
        null=True,
    )
    mp_token_type = models.CharField(
        verbose_name='Tipo de token',
        help_text='Tipo de access token',
        max_length=32,
        blank=True,
        null=True,
    )
    mp_expires_in = models.PositiveIntegerField(
        verbose_name='Expira en',
        help_text='Tiempo que expira el token',
        blank=True,
        null=True,
    )
    mp_scope = models.CharField(
        verbose_name='Permisos del token',
        help_text='Accesos brindados por el marketplace',
        max_length=255,
        blank=True,
        null=True,
    )
    mp_refresh_token = models.CharField(
        verbose_name='Token de refresco',
        help_text='Token para actualizar el token de acceso. Cada 6 meses se vence.',
        max_length=255,
        blank=True,
        null=True,
    )

Haciéndo eso sigue siendo compatible con no-marketplaces?
