Django ImageField in RestFramework

Question

I'm new at Django. my project is in DjangoRestFramework

This project has a user:

models.py:

class Users(models.Model):
    name = models.CharField(max_length=20, null=True)
    lastName = models.CharField(max_length=50, null=True)
    phone = models.IntegerField(unique=True, null=False, default='phone')
    password = models.CharField(max_length=25, null=True)
    natNum = models.IntegerField(unique=True, null=True)
    degImage = models.ImageField(upload_to='Images/degrees/', null=False, blank=False,default='Images/degrees/None/no-img.jpg')
    natImage = models.ImageField(upload_to='Images/nationalCards/', null=False, blank=False,default='Images/nationalCards/None/no-img.jpg')
    sex = models.CharField(null=True, max_length=1)
    province = models.CharField(null=True, max_length=20)
    city = models.CharField(null=True, max_length=40)
    job = models.CharField(null=True, max_length=20)
    code = models.CharField(max_length=4, null=True)
    last_seen = models.DateTimeField(default=django.utils.timezone.now)
    points = models.IntegerField(null=False, default=0)
    scorers = models.IntegerField(null=False, default=0)

and in views.py I made a function for registeration but for degImage and natImage there is a problem.

views.py

@api_view(["POST"])
@parser_classes((MultiPartParser, JSONParser))
def register(request):
    user_data = request.data
    if user_data:
        serializer = UserSerializers(data=user_data)

        if serializer.is_valid():

            phone_number = serializer.validated_data["phone"]

            try:
                found_user = Users.objects.get(phone=phone_number)
            except Users.DoesNotExist:
                found_user = None

            if found_user:
                return Response({
                    "code": 211,
                    "status": "successfull",
                    "message": "user already exists, try to login"
                })
            else:
                destination = serializer.validated_data['phone']
                message = str(random.randint(1000, 9999))
                url = "https://panel.asanak.ir/webservice/v1rest/sendsms/?Username=***&Password=***&Source=***&Destination={}&message={}"
                url = url.format(destination, message)
                r = requests.get(url)
                r.json()
                registerInfo = {
                    'name': serializer.validated_data['name'],
                    'lastName': serializer.validated_data['lastName'],
                    'phone': serializer.validated_data['phone'],
                    'natNum': serializer.validated_data['natNum'],
                    'password': serializer.validated_data['password'],
                    'degImage': serializer.validated_data['degImage'],
                    'natImage': serializer.validated_data['natImage'],
                    'sex': "",
                    'province': "",
                    'city': "",
                    'job': "",
                    'code': message
                }

                serializer.save(registerInfo)

                return Response({
                    "code": 200,
                    "status": "successfull",
                    "message": "code was sent try to validate code"
                })
            return Response({
                "status": "successfull",
                "error": "user created :)"
            })

        else:
            return Response({
                "status": "error",
                "error": "Bad request"
            })
    else:
        return Response({
            "status": "error",
            "error": "Empty request"
        })

serializers.py

class UserSerializers(serializers.Serializer):
    name = serializers.CharField(required=True)
    lastName = serializers.CharField(required=True)
    phone = serializers.CharField(required=True)
    natNum = serializers.IntegerField(required=True)
    password = serializers.CharField(required=True)
    degImage = serializers.ImageField(required=False)
    natImage = serializers.ImageField(required=False)
    code = serializers.CharField(required=False)

    def save(self, validated_data):
        user = Users(
            name=validated_data['name'],
            lastName=validated_data['lastName'],
            phone=validated_data['phone'],
            natNum=validated_data['natNum'],
            password=validated_data['password'],
            degImage=validated_data['degImage'],
            natImage=validated_data['natImage'],
            code=validated_data['code']
        )
        user.save()
        return user

In Postman when i choose a file it's OK and works fine

But in developing android and iOS they can't post a image in json with other fields

and i want to know is there any problem in my coding that makes this problems or any thing which we can do to solve this

Answer 1

we cannot send a filetype with header "Content-Type: application/json". Please make sure your request header should be set to "Content-Type: multipart/form-data". As you are using parsers MultiPartParser, JSONParser it will parse the file data as well as json data.
