Change database default connection if needed

[masterix21]

Using packages like Laravel Passport or Laravel Sanctum (and many others) could be useful to switch the default database connection to "tenant" instead of "landlord".

Using the config file, now it is merely possible:

/*
 * Using `\Spatie\Multitenancy\Tasks\SwitchTenantDatabaseTask`, could be useful to
 * set up the tenant database connection as default connection.
 */
'tenant_database_connection_as_default' => true,

Couldn't you just set a tenant database as the default in the. databases.php config file if you'd like that?

Your reasoning is not wrong, but there seem to be problems. Following the past issues, appears to be a solution to the questions:

• Sanctum package not switching the database connection #51
• Multitenancy with Passport, Scheduling, Filesystem #29 (comment)

I tried and seemed necessary. Furthermore, could be a way to skip the "--database=" argument with migrations, or other commands where the "--database=" argument is unimplemented (and there are a lot of packages).

Your reasoning is not wrong, but there seem to be problems.

I don't fully understand the problem or how this PR solves the problem, but adding an extra configuration option for something that can already be done in configuration seems off.

I'd prefer a solution where no config option is added. Maybe the current implementation can be changed in a non-breaking way that solves the problem?

See the attached video where I tried to explain the problem using Tinkerwell. I don't know if there are other solutions, but changing the default database connection works.

I will inspect better in the problem, but if you have an idea or understand what should be, please keep me updated.

Another example.

It happens when you use a model without UsesTenantConnection (or UsesLandlordConnection).

[masterix21]

A partial solution (already tested) could be a trait (UsesMixedConnection) with:

public function getConnectionName()
{
        return Tenant::checkCurrent()
            ? 'tenant'
            : 'landlord';
}

But it means that you must extend all original models with new ones that use the trait.
