How to properly add a foreign key in Symfony?

Question

symfony

I have a comments relation with post.
For a post, I will be getting comments using the getComments method. You don't need to receive posts to comment.
How to create a relationship so that there is an addition of a foreign key? And where is it better to do it in migration or separately in entity Comments?

Answer 1

Use One-To-Many , and it is the bidirectional type of connection. With the correct settings, all necessary foreign keys will be created during the generation of migrations.
