There are a few options to do this:

A) On pre_save signal. In case you want to do check before you store an object in DB:

@receiver(pre_save, sender=OrderRecord)
def handler_order_check(sender, instance, **kwargs):
    ...

B) On post_save signal or in Molde.save method, a check will be done after object is created:

@receiver(post_save, sender=OrderRecord)
def handler_order_check(sender, instance, **kwargs):
    ...

C) On admin form. In case you want to keep the check in admin side only, when objects created from f/e & shell will not have such check, related docs.

I would recommend using A, as it does the check every time you create (or update, depends on implementation) OrderRecord.
