Django在FOO_set中使用了哪个字段？

Question

I am little bit comfused. Lets say I have such models.

models.py :

class Company(models.Model):
    name = models.CharField(blank=False, null=False)

class Game(models.Model):
    developer = models.ForeignKey(Company, on_delete=models.CASCADE)
    publishers = models.ManyToManyField(Company)

If I use next code:

current_company = Company.object.get(pk=1)
current_company.game_set.all()

as I understand it return all games of current_company , but what field (developer or publishers) Django used?

Answer 1

But this code wouldn't be valid, for precisely this reason. If you tried to run it, Django would tell you that there was a conflict in the reverse relation.

If you have two relationships pointing to the same model, you need to explicitly set related_name on one of them to avoid this conflict.
