ModelManagerInterface and getParentMetadataForProperty()

[dmaicher]

Feature Request

Inside the AbstractTypeGuesser we are calling Sonata\AdminBundle\Model\ModelManagerInterface::getParentMetadataForProperty but this method is not part of that contract.

So we are actually expecting a Sonata\DoctrineORMAdminBundle\Model\ModelManager for it to work.

As @VincentLanglet suggested we could

• extend the ModelManagerInterface and add this method
• move this method somewhere else

Or any other ideas?

I created sonata-project/SonataAdminBundle#6701 for this, but I haven't tried it yet.

The getParentMetadataForProperty method was also used in the fixDescription method of our builders.
@dmaicher you removed it from FormContractor, ListBuilder and ShowBuilder, but you had issues with the tests for the DatagridBuilder. With https://github.com/sonata-project/SonataDoctrineORMAdminBundle/pull/1297/files, it will be definitely removed from the builders.

So indeed, we just have to focus about the TypeGuesser usage.

$this->guesser->guessType($admin->getClass(), $fieldDescription->getName(), $admin->getModelManager())

This could be easily migrated to

$this->guesser->guessType($fieldDescription)

Because as a first step, we can change the code inside guessType to add

$admin = $fieldDescription->getAdmin();
$class = $admin->getClass();
$modelManager = $admin->getModelManager();

And keep the same code.

Note that currently, when guessType is called, we did not attach the admin
It's done instead in the fixFieldDescription method:
https://github.com/sonata-project/SonataDoctrineORMAdminBundle/blob/3.x/src/Builder/DatagridBuilder.php#L74
So there is something to change about this.
We can move the setAdmin call from fixFieldDescription to addFilter.

I also notice that the fixFieldDescription is in every builder, but is only called in the SonataAdmin::FormMapper https://github.com/sonata-project/SonataAdminBundle/search?q=fixFieldDescription ; there is no need to make it public in other builders.
A maybe better idea could be to move the addFilter and addField to the SonataAdmin code. When I look at the code I think it just require a BuilderInterface::getGuesser method and a DatagridBuilderInterface::getFilterFactory method.
