Hi. Please include full reproducible code + traceback.

[Gujjar95]

Below is my Code, Traceback and schema and instances i have posted above

def post(self, request, id):
    	received_json_data = json.loads(request.body.decode("utf-8"))
    	validate(instance = received_json_data, schema = schema)
    	sender = User.objects.filter(pk=int(received_json_data['sender'])).first()
    	receiver = User.objects.filter(pk=int(received_json_data['receiver'])).first()
    	transaction_type = received_json_data['transaction_type']
    	transaction_status = received_json_data['transaction_status']
    	transaction_amount = int(received_json_data['transaction_amount'])
    	transaction_receiver_address = received_json_data['transaction_receiver_address']
    	transaction_sender_address = received_json_data['transaction_sender_address']
    	transaction_currency_involved = received_json_data['transaction_currency_involved']
    	if sender is not None:
    		temp_sender = WalletBalance.objects.get(wallet=Wallet.objects.filter(user=sender),wallet_currency=transaction_currency_involved)
    		if temp_sender.currency_address != transaction_sender_address:
    			return HttpResponse("Sender address does not matches")
    		if transaction_amount > temp_sender.balance:
    			return HttpResponse("Insufficient balance")
    	if receiver is not None:
    		temp_receiver = WalletBalance.objects.get(wallet=Wallet.objects.filter(user=receiver),wallet_currency=transaction_currency_involved).currency_address
    		if temp_receiver != transaction_receiver_address:
    			return HttpResponse("Receiver address does not matches")
    	transaction_new = Transaction(sender=sender, receiver=receiver, transaction_type=transaction_type,transaction_status=transaction_status, transaction_amount=transaction_amount,transaction_sender_address=transaction_sender_address,transaction_receiver_address=transaction_receiver_address,transaction_currency_involved=transaction_currency_involved)
    	transaction_new.save()
    	return HttpResponse("OK")

@Gujjar95 thanks, but I can't reproduce with that.

By reproducible -- I need code I can run that is self contained.

Your issue is going to be somewhere you passing in a TextWrapper, but in order to see where, I need the above.

[Gujjar95]

@Julian
Sorry for the above, I am new to the community and learning all terminology.
Above method is an API call for post in which body contain JSON.Without validating function everything is working fine.So pb is arising after adding the validate.in the validate I am calling instance and schema which I posted in the first comment.
If you need full code then it is too many files to post here.

[Julian]

No worries, but without a fully reproducible set of code I can't really help -- you need to work on stripping away all the parts of your code that are unrelated and provide a minimal, self contained example.

I can tell from your traceback that you must be doing something like passing in open(someschemafile) rather than the actual contents of the file, but when filing issues you need to do a bit of work upfront to reduce down to something that you can share here if you can't find your issue yourself.

Hopefully the above is enough to point you in the right direction.

[Gujjar95]

yup you are right got it now ,

__location__ = os.path.realpath(
    os.path.join(os.getcwd(), os.path.dirname('views.py')))
schema = open(os.path.join(__location__,'apis/json_schema.json'))
