Re: Issues saving hex format data to binaryfield

I have the model set up as a binaryfield. The problem is I have no idea how to save the information to it. I can retrieve information from it easy enough but if I try and enter in new information, saved in the same format as that it returns

Here's what I have in model.py

class Users(models.Model):

    ....

    rfid = models.BinaryField(editable = True, unique=True, blank=True, null=True)

    ....

    def set_rfid(self,rfid_new):

        print self.rfid # print the existing object data

        try:

            self.rfid = bytearray(rfid_new)

            print self.rfid

        except Exception as ex:

            template = "An exception of type {0} occured. Arguments:\n{1!r}"

            message = template.format(type(ex).__name__, ex.args)

            print message

It doesn't raise an exception but it also doesn't save it into the field. 

This is the print out (Standard PostgreSQL escape format):

E\xa343c5ea

E\x52577ade

Any help would be appreciated. 

Thanks,

Brian
