class Travel(models.Model):
tags = models.ManyToManyField(
Tag,
related_name='travels', )
route_places = models.ManyToManyField(
RoutePlace,
related_name='travels', )
coordinate = models.F...

class Child(models.Model):
parent = models.ForeignKey(Parent)
child_name = models.CharField(max_length=80)
And we want to return a respo...
