problems deserializing json object

[Malcolm MacKinnon]

I'm having difficulty deserializing a json object. I'm using django
appengine patch, so the models aren't the same as django's, but they are
very similar:

class Cust(db.Model):
    custno = db.StringProperty(required=True)
    company = db.StringProperty(required=True)
    contact = db.StringProperty(required=False)
    address1 = db.StringProperty(required=False)
    address2 = db.StringProperty(required=False)
    city = db.StringProperty(required=True)
    state = db.StringProperty(required=False)
    zipc = db.StringProperty(required=False)
    country = db.StringProperty(required=False)
    phone = db.StringProperty(required=False)
    salesmn = db.StringProperty(required=True)
    email = db.StringProperty()

    def __unicode__(self):
        return self.custno + " : " + str(self.company)+" :
"+str(self.city)+" : "+str(self.state)

class Cust_List(db.Model):
    custno = db.StringProperty(required=True)
    companies = db.TextProperty(required=True) #customer list as json object

Note that the json object is stored in the db.TextProperty companies, and is
composed of more than a 1000 customers, all of which are also individually
stored in the model, Cust . I query the json object for a customer list,
since it saves CPU time on the appengine.

Here's what happens when I try to decode the json string object:
>>> from sport.models import Cust_List
>>> from django.core import serializers
>>> a=Cust_List.all()
>>> b=a.get() #returns the only and only data item in this model, which is a
json object previously stored in the datastore.
>>> c=serializers.deserialize('json', b.companies)
>>> d=list(c)
>>> e=len(d)
>>> e
1057
>>> b
etc...

Note that I just get returned a unicode representation of my model, Cust.
But the contact information, address information, and so on disappears in
the deserialized object. Any thoughts on why or what I'm doing wrong?

Thanks for any help or ideas!
