Question

I have oneToMany bidirectional relationship between User and Address. In yml file, do I need to specify the user_id field for Address entity? I did that and when I generated entity getters it didn’t create getUser() or setUser() instead getUserId() and setUserId()

Answer 1

On your Address entity you would have a $user field relating to a User entity, not user_id relating to an integer.

Remember you are mapping in terms of entities with Doctrine, not SQL or relational database tables. Try to think in terms of your business model as much as possible, Doctrine will handle the rest and internally it will know to make a foreign key related to a user id in the address table.

User mapping:

oneToMany:
  addresses:
    targetEntity: Address
    mappedBy: user

Address mapping

manyToOne:
  user:
    targetEntity: User
    inversedBy: addresses
