Question

Skipper Build 3.2.22.1624
Symfony 4.4.1
Doctrine ORM 2.7.0

I have a problem with our setup and combined unique keys. The column definition is exported "as-is" (with camelCase column names). But in our doctrine.yaml we have:

naming_strategy: doctrine.orm.naming_strategy.underscore_number_aware

The resulting export is:

* @ORM\Table(uniqueConstraints={@ORM\UniqueConstraint(name="CityUnique", columns={"city","countryCode"})})

which leads to the error:

$ php bin/console make:mig

In SchemaException.php line 82:

 There is no column with name 'countryCode' on table 'city'.

The db-naming-strategy on the index is set to underscore-lower, but to no effect.

Edit: I see, I have to set the db-naming-strategy on the Bundle! Then it's exported correctly. But shouldn't Skipper also consider the setting on index level? What does that do anyway?

.

Minimal working example:
