Unable to edit/create entries with associations

[alexgit2k]

Describe the bug When entities with associations are used, for example many pupils to one school, it is not possible to administrate the entries with the association:

• View - Association-column is not shown
• Edit - Association can not be changed, because associations-field is not displayed
• Create - Newly created entries fail to save because association can not be selected:

  An exception occurred while executing a query: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'school_id' cannot be null

To Reproduce

symfony new application --full
cd application

symfony console make:entity School
name, string, 255, no

symfony console make:entity Pupil
school, ManyToOne, School, no, yes, pupils, yes
firstname, string, 255, no
surname, string, 255, no

symfony console make:migration
symfony console doctrine:migrations:migrate

symfony composer req admin
symfony console make:admin:dashboard
symfony console make:admin:crud # App\Entity\School
symfony console make:admin:crud # App\Entity\Pupil

(OPTIONAL) Additional context Associations in both directions have been correctly set by make:entity:

• src/Entity/School.php

  ...
  /**
   * @ORM\OneToMany(targetEntity=Pupil::class, mappedBy="school", orphanRemoval=true)
   */
  private $pupils;
  ...

• src/Entity/Pupil.php

  ...
  /**
   * @ORM\ManyToOne(targetEntity=School::class, inversedBy="pupils")
   * @ORM\JoinColumn(nullable=false)
   */
  private $school;
  ...
