i added the field from models.py The rest is a snipped from a celery job so no views or templates only pure data processing. — user10000033

What are you trying to do with user.acc_balance('confirmed')? As the error says, acc_balance is an integer, it does not know what to do with the 'confirmed' param that you are passing. — gdef_

yes i guess this is my mistake i simply want to save the vaule of "confirmed" to the DB field "user.acc_balance" nothing more, nothing less. — user10000033

What's with the update_or_create part? Do you want to save the data in the user that you have as user? If i understand correctly what you want is to save the confirmed value from decoded_balance to the user's acc_balance field. Is that correct? — gdef_

I think this is what you are trying to do:

decoded_balance = json.loads(check_balance) 
user.acc_balance = decoded_balance["confirmed"]
user.save()

You already have the user, just update it's acc_balance field and save it.

Also, you might want to check how to parse json. For example, in this case you have something like this:

decoded_balance
# eg: {'confirmed': 2, 'unconfirmed': 3}
decoded_balance["confirmed"]
# 2

i don't know the larger scope of your code, but if you already have the user in a variable as in this case, you are updating the acc_balance field by assigning a new value and saving it. You would use update_or_create if you don't know for sure that the user exists, also you would need to pass all the other fields necessary to get or create a correct user, not just the acc_balance
