I have been working on this issue. Here is what I have so far.
My Model and pre_save
information--------------------------------------------------------------------------------------------:
class walmart_query_history(models.Model):
storeNumber = models.CharField(max_length=10)
receiptDate = models.DateField(auto_now=False, auto_now_add=False)
cardType = models.ForeignKey(walmart_query_history_card_type,
on_delete=models.CASCADE)
purchaseAmount = models.DecimalField(max_digits=13, decimal_places=2)
lastFour = models.CharField(max_length=4)
class Meta:
unique_together = (('receiptDate', 'purchaseAmount'),)
def validate_response_ask_walmart(*args, instance, **kwargs):
pewee = instance.receiptDate
pewee = pewee.strftime('%m-%d-%Y')
data = call_command('validate_response_query_walmart',
instance.storeNumber, str(pewee), instance.cardType,
str(instance.purchaseAmount), instance.lastFour)
valid_ser = ValidateFormSerializer(data=data)
if valid_ser.is_valid():
post_data = valid_ser.validated_data
else:
print(valid_ser.errors)
pre_save.connect(validate_response_ask_walmart,
sender=walmart_query_history)
Contents of my validate_response_ask_walmart
file------------------------------------------------------------------------------------------------:
class Command(BaseCommand):
help = 'Reads Receipts'
def add_arguments(self, parser):
parser.add_argument('storeId', type=str)

parser.add_argument('cardType', type=str)
parser.add_argument('total', type=str)
parser.add_argument('lastFourDigits', type=str)

#tester = base_JSON

self.stdout.write(type(base_JSON))
My serializer
file-----------------------------------------------------------------------------------------------------------------------------------------------
from rest_framework import serializers
class ValidateFormSerializer(serializers.Serializer):
tcNumber = serializers.CharField(max_length=255,
source='receipts[0]tcNumber')
----------------------------------------------------------------------------------------
I keep getting the error code of:
AttributeError: type object 'dict' has no attribute 'endswith'
What am I missing?
