Uploaded Model Data WIth DRF Data Does Not Save - django

Question

I'm trying to upload a photo along with other data for my CustomerDetails model via an api endpoint. The data seems to save but, when I check my table, there is no data present.
Here is my model:
class CustomerDetails(models.Model):
Sizes = (
('Sizes', (
('small', 'small'),
('medium', 'medium'),
('large', 'large'),
)),
)
CATEGORIES = (
('Usage', (
('Headache', 'Headache'),
('Backaches', 'Insomnia'),
('Menstrual Cramps & Pains','Menstrual Cramps
)),
)
CUSTYPE = (
('Customer Type',(
('Athlete', 'Athlete'),
('Non-Athlete', 'Non-Athlete'),
)),
)
age = models.IntegerField(default="21", blank=True)
nick_name = models.CharField(max_length=500, blank=True)
average_order = models.FloatField(default = "0.0", blank=True)
completed_orders = models.IntegerField(default = "0", blank=True)
customer = models.ForeignKey(Customer, on_delete=models.CASCADE, related_name='customer')
customer_type = MultiSelectField(choices=CUSTYPE, default = CUSTYPE, max_length=100)
current_selfie = models.ImageField(upload_to= 'sefies/', blank=True, default='')
favorite_color = MultiSelectField(choices=TYPE, max_length=100)
interested_in = MultiSelectField(choices=CATEGORIES, max_length=1000)
last_signin = models.DateTimeField(default = timezone.now)
liked_stores = models.ManyToManyField('Stores')
liked_products = models.ManyToManyField('Product')
phone = PhoneField(blank=True, help_text='Contact phone number')
shares = models.IntegerField(default = "0", blank=True)
signup = models.DateTimeField(default = timezone.now)
def __str__(self):
return self.customer.user.get_full_name()
Here are my serializers & Url
url(r'^api/customer/create_customer_details/$', apis.CustomerDetailViewset.as_view()),
class CustomerDetailUploader(serializers.ModelSerializer):
customer = CustomerDetailSerializer()
current_selfie = serializers.SerializerMethodField()
def get_current_selfie(self, store):
request = self.context.get('request')
current_selfie_url = CustomerDetails.current_selfie.url
return request.build_absolute_uri(current_selfie_url)
class Meta:
model = CustomerDetails
fields = ('nick_name', 'customer', 'current_selfie', 'favorite_color', 'interested_in', 'customer_type')
Here is the apiView I'm using:
class CustomerDetailViewset(APIView):
parser_classes = (MultiPartParser, FormParser)
def post(self, request, *args, **kwargs):
file_serializer = CustomerDetailUploader(data=request.data)
if file_serializer.is_valid():
file_serializer.save()
return Response(file_serializer.data, status=status.HTTP_201_CREATED)
return Response(file_serializer.errors, status=status.HTTP_400_BAD_REQUEST)
I'm trying to create a new customerDetails page for every user when they sign up, assign the data to a Customer, and save the details. Everytime I try to call the function, I do get the success message:
[15/Feb/2019 22:56:10] "POST /api/customer/create_customer_details/?access_token=U3EvAbo1HhOwNAgcEYUR4WOegul6ye HTTP/1.1" 201 99
Can anyone let me know how I can fix this?

You can try this save image (Base64) using DRF
serializer.py
class Base64ImageField(serializers.ImageField):
def to_internal_value(self, data):
from django.core.files.base import ContentFile
import base64
import six
import uuid
# Check if this is a base64 string
if isinstance(data, six.string_types):
# Check if the base64 string is in the "data:" format
if 'data:' in data and ';base64,' in data:
# Break out the header from the base64 content
header, data = data.split(';base64,')
# Try to decode the file. Return validation error if it fails.
try:
decoded_file = base64.b64decode(data)
except TypeError:
self.fail('invalid_image')
# Generate file name:
file_name = str(uuid.uuid4())[:12] # 12 characters are more than enough.
# Get the file name extension:
file_extension = self.get_file_extension(file_name, decoded_file)
complete_file_name = "%s.%s" % (file_name, file_extension, )
data = ContentFile(decoded_file, name=complete_file_name)
return super(Base64ImageField, self).to_internal_value(data)
def get_file_extension(self, file_name, decoded_file):
import imghdr
extension = imghdr.what(file_name, decoded_file)
extension = "jpg" if extension == "jpeg" else extension
return extension
class CustomerDetailUploader(serializers.ModelSerializer):
customer = CustomerDetailSerializer()
current_selfie = Base64ImageField()
class Meta:
model = CustomerDetails
fields = ('nick_name', 'customer', 'current_selfie', 'favorite_color', 'interested_in', 'customer_type')
in api.py
class CustomerDetailViewset(APIView):
parser_classes = (MultiPartParser, FormParser)
def post(self, request, *args, **kwargs):
file_serializer = CustomerDetailUploader(data=request.data)
if file_serializer.is_valid():
file_serializer.save()
return Reponse ({})
hope it help for your problem

Answer 2

Maybe you have some errors, but you are not seeing them, because you're return always 201. The first Response should be inner the if branch.
Your code:
def post(self, request, *args, **kwargs):
file_serializer = CustomerDetailUploader(data=request.data)
if file_serializer.is_valid():
file_serializer.save()
return Response(file_serializer.data, status=status.HTTP_201_CREATED)
return Response(file_serializer.errors, status=status.HTTP_400_BAD_REQUEST)
correct code:
def post(self, request, *args, **kwargs):
file_serializer = CustomerDetailUploader(data=request.data)
if file_serializer.is_valid():
file_serializer.save()
return Response(file_serializer.data, status=status.HTTP_201_CREATED)
return Response(file_serializer.errors, status=status.HTTP_400_BAD_REQUEST)
