Django Model Definition Race

Question

How do you deal with the case where you have a model (A) that relies on model (B) being defined, but model (B) also relies on model(A) being defined.

For instance, I hav

Answer 1

class event(models.Model):
  competition_start = models.DateField() 
  competitors = models.ManyToManyField('MODULE.picture')
  results = models.CommaSeparatedIntegerField(max_length=20)
  ...

Also, by definition you can't have both a one-to-one and a many-to-many. I think you want the relationship on the Picture class to be a foreignkey not a one-to-one.

Answer 2

You can pass in the string of the class name to the definition of OneToOne and ForeignKey and have it evaluated "lazily".

competitors = models.ManyToManyField('picture')

Also, the convention for model class names is camel-case (e.g. 'picture' => 'Picture', 'event' => 'Event').
