Add Binary data into django rest framework API

Question

model.py

class TblSnapshot(models.Model):
    url = models.CharField(max_length=500)
    snapshot = models.BinaryField()

I want to add Binary Data in API, but it's generating error

TypeError at /api
__str__ returned non-string (type memoryview)

You'll need to implement a custom field ( as per here) . This is how your serializer would look for such model

class BinaryField(serializers.Field):
    def to_representation(self, value):
        return value.decode('utf-8')

    def to_internal_value(self, value):
        return value.encode('utf-8')

class TblSnapshotSerializer(serializers.ModelSerializer):
    class Meta:
        model = TblSnapshot
        fields = ('id', 'url', 'snapshot')

    snapshot = BinaryField()
