Doctrine yaml for a One-To-Many And One-To-One Relationship?

With Doctrine, it can often be better to only define the relationship on one side (usually the owning side) and let Doctrine work out the rest. Here, you've got a cascading deletion which looks to be going both ways. Try altering your schema to.

Richsage the only issue I had with your solution, is that for me, in the FileDetail: definition, the file_id: had to have primary: true.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
