Question regarding lazy

[Hari K T]

Hi, 

I hope all are doing good. I am having a trouble setting lazy object in di.

This is the code .

$di->set('default_connection', $di->lazyNew('Aura\Sql\ExtendedPdo'));

        $di->set('query_factory', $di->lazyNew('Aura\SqlMapper_Bundle\Query\ConnectedQueryFactory'));

        $di->set('connection_locator', $di->lazyNew('Aura\Sql\ConnectionLocator'));

        $di->params['Aura\Sql\ExtendedPdo']['dsn'] = getenv('CONNECTION_DSN');

        $di->params['Aura\Sql\ExtendedPdo']['username'] = getenv('CONNECTION_USERNAME');

        $di->params['Aura\Sql\ExtendedPdo']['password'] = getenv('CONNECTION_PASSWORD');

        $di->params['Aura\SqlQuery\QueryFactory']['db'] = getenv('CONNECTION_TYPE');

        $di->params['Aura\Sql\ConnectionLocator']['default'] = function () use ($di) {

            return $di->get('default_connection');

        };

        $di->params['Aura\SqlMapper_Bundle\Query\ConnectedQueryFactory']['query'] = $di->lazyNew('Aura\SqlQuery\QueryFactory');

I need $di->params['Aura\Sql\ConnectionLocator']['default']  to be a closure. But I am wondering what is the best way to acheive it.

I have tried lazy but it didn't worked as expected.

Thank you.

Hi Hari,

I'm not sure I understand your question correctly, but here is something that worked for me.

$di->set('database', $di->lazyNew(

    'Aura\Sql\ExtendedPdo',

        array(

        'dsn' => 'mysql:dbname=phptoday;host=127.0.0.1',

        'username' => 'root',

        'password' => 'root'

    )

));

$di->set('connection_locator', $di->lazyNew('Aura\Sql\ConnectionLocator'));

$di->params['Aura\Sql\ConnectionLocator']['default'] = function () use ($di) {

    return $di->get('database');

};

$di->params['MyApp\Domain\Services\UserService']['pdo'] = $di->get('connection_locator')->getDefault();

Are you looking for this?

Cheers

Shameer

Did you try lazyGet()? It will return a callable.

Hi Shameer, 

 

I'm not sure I understand your question correctly, but here is something that worked for me.

$di->set('database', $di->lazyNew(

    'Aura\Sql\ExtendedPdo',

        array(

        'dsn' => 'mysql:dbname=phptoday;host=127.0.0.1',

        'username' => 'root',

        'password' => 'root'

    )

));

$di->set('connection_locator', $di->lazyNew('Aura\Sql\ConnectionLocator'));

$di->params['Aura\Sql\ConnectionLocator']['default'] = function () use ($di) {

    return $di->get('database');

};

Yes this is what I am currently doing. But was wondering if Di itself have some sort of way to make it callable.other than 

$di->params['Aura\Sql\ConnectionLocator']['default'] = function () use ($di) {

            return $di->get('default_connection');

        };

 

$di->params['MyApp\Domain\Services\UserService']['pdo'] = $di->get('connection_locator')->getDefault();

Are you looking for this?

Yes, but I want to get rid of using the closure and passing the di object to it :) .

Hey Brandon Savage, 

When you said lazyGet first thought was it will not return callable.

Then I understood you were mentioning to make use of 

$di->params['Aura\Sql\ConnectionLocator']['default'] = $di->lazyGet('Aura\Sql\ExtendedPdo')

But I was making use of service so that the same connection can be used else where.

$di->set('default_connection', $di->lazyNew('Aura\Sql\ExtendedPdo'));

The idea of same connection is when using Aura.Auth and passing the pdo instance etc.

But in the use of $di->lazyGet('Aura\Sql\ExtendedPdo') I don't think it will be making use of same connection. So the best seems the closure itself.

Thanks!
