Query multiple models with one value
- by swoei
I have multiple models which all have a FK to the same model.
All I know is the FK how can I determine which of the models has the FK attached?
Below an example to clearify:
class ModelA(models.Model):
title = models.CharField("title", max_length=80)
class ModelB(models.Model):
fk = models.ForeignKey(ModelA)
class ModelC(models.Model):
fk = models.ForeignKey(ModelA)
How can I figure out without using a try/except on each model whether B or C has the FK?
(The FK can only be in one of them, for the record in this case I only added two models but in the real world app there are multiple possible x amount of models which have the FK to modelA)
