django - ManyToMany field, check if relation exists -

- 

class player(models.model):     item = models.foreignkey(test)     box = models.manytomanyfield(test)

views:

a = player.object.get(id=1) b = player.objects.get(id=5)

how check if a.item in manytomany relation b.box?

it's pretty simple:

playes.objects.filter(pk=a.pk, box__pk=b.pk).exists()
