Doctrine2: OneToMany on mapped superclass


My DB structure is as follows:

work:

comment:

WorkComment has a ManyToOne relation to Work:

@ManyToOne(targetEntity="Work", inversedBy="comments")

Work has a OneToMany relation to WorkComment:

@OneToMany(targetEntity="WorkComment", mappedBy="work")

The problem is that Doctrine gives me this error while updating the schema:

[Doctrine\ORM\Mapping\MappingException]
It is illegal to put an inverse side one-to-many or many-to-many association on
mapped superclass 'Acme\...\AbstractImageWork#comments'.

I guess this has something to do with the MappedSuperclass AbstractImageWork stuck in the middle between Work and PhotoWork, but I didn't actually put this relation on the MappedSuperclass, but on the CTI table.. so why will Doctrine behave like this?

Any ideas?


Solution

  • In some cases, when you have such error when inherit from the class that is tagged as @ORM\MappedSuperclass, try to change your properties access level from private to protected
