class Incident(models.Model):
    owner = models.ForeignKey(User)

class IncidentData(models.Model):
    key = models.CharField(max_length=255)
    value = models.CharField(max_length=255)
    incident = models.ForeignKey(Incident)


## Or, if you want to have manager-level control for the IncidentData:


class IncidentDataType(models.Model):
    key = models.CharField(max_length=255)

class IncidentData(models.Model):
    key = models.ForeignKey(IncidentDataType)
    value = models.CharField(max_length=255)
    incident = models.ForeignKey(Incident)
