How to access nested reference property?

[StanislavUngr]

Hello guys. So I have this issue where i need to access 2nd level reference's property. How do I do this?

This is my schema:

Entity\City:
   postalCodes: string[];

Entity\Address:
   city: Entity\City
   postalCode: random of (Entity\City->postalCodes)

YAML for alice:

App\Entity\City\City:
  city_{1..100}:
    __construct:
      name: <city()>
      district: '@district_*'
    postalCodes (unique): 5x <postcode()>

App\Entity\Address\Address:
  address_{1..100}:
    __construct:
      city: '@city_*'
      postalCode: '<randomElement(@self->postalCodes)>'
      type: <randomEnum(AddressType)>

However i get errors everytime i try to invoke <randomElement(@self->postalCodes)>:

[Nelmio\Alice\Throwable\Exception\ObjectNotFoundException]
  Could not find the object "address_1" of the class "App\Entity\Address\Address".

or <randomElement($city->postalCodes)>:

[Nelmio\Alice\Throwable\Exception\Generator\Resolver\UnresolvableValueException]
  Could not evaluate the expression "$city".

It seems only 1st level of nesting is allowed.

Do you have any fixes/workarounds how to solve this? Thanks in advance..

Hello,

Like you have 100 city and 100 address, maybe you could try this:

App\Entity\Address\Address:
  address_{1..100}:
    __construct:
      city: '@city_<current()>'
      postalCode: '<randomElement(@city_<current()>->postalCodes)>'
      type: <randomEnum(AddressType)>

Hello,

although this is a temporary fix and destroys logic of 1:N relation, for our testing purposes its enough atm.

Thanks for your help 👍

PS: PR to implement this feature is welcomed, of course 😄

The first variant cannot indeed work due to conflicting with the existing features.

The second however should work, but maybe @self->city->postalCodes will do?

The @self->city->postalCodes syntax doesn't works unfortunately, is there another way to access properties through multiple relations ?

You should try this: @self->city.postalCodes, use the . from the second level to access the sub property.
