Answer 1

The problem is that setConnection() works on an instance of a class, but the create() method is a static method on the class itself. In your repository, $this->product is an instance of the Product class. Using setConnection() on this instance before doing queries will work fine, but you'll need to do a little more manual work if you want to use separate connections on the static methods (such as create()).

All the create() method does is instantiate a new instance with the given attributes and then call save(). So, instead of calling create() on the Product model, you'll just need to do this manually:

class ProductRepository {
    public function create(array $attributes, $connection = null) {
        $product = $this->product->newInstance($attributes);
        $product->setConnection($connection ?: $this->product->getConnectionName());
        $product->save();
        return $product;
    }
}

You could also override the static create() method on the Product model to accept a connection, as well.

class Product extends Model {
    public static function create(array $attributes, $connection = null) {
        $model = new static($attributes);
        $model->setConnection($connection ?: $this->connection);
        $model->save();
        return $model;
    }
}

class ProductRepository {
    public function create(array $attributes, $connection = null) {
        $connection = $connection ?: $this->product->getConnectionName()
        return $this->product->create($attributes, $connection);
    }
}
