Question

Assume I have this model :

class Task(models.Model):
    title = models.CharField()

Now I would like that a task may be relates to another task. So I wanted to do this :

class Task(models.Model):
    title = models.CharField()
    relates_to = ForeignKey(Task)

however I have an error which states that Task is note defined.
Is this “legal” , if not, how should I do something similar to that ?

Answer 1

class Task(models.Model):
    title = models.CharField()
    relates_to = models.ForeignKey('self', on_delete=models.CASCADE)
