django add pdf to a request value - django

Question

in the following request I receive a total of 10 pdfs which I must combine in one document
once this is done I have to upload it to the client model which stores the files in aws s3, once I pass the file with all the pdfs together it gives me the following error
{
"error": true,
"message": {
"documents": [
"The submitted data was not a file. Check the encoding type on the form."
]
}
}
this is mi code
merger = PdfFileMerger()
for x in request.FILES:
print(request.FILES[x])
merger.append(request.FILES[x])
merger.write(os.path.join(os.path.dirname(os.path.dirname(os.path.abspath(__file__))), 'media/' + str(getUser.id) + '.pdf'))
merger.close()
pdf = open(os.path.join(os.path.dirname(os.path.dirname(os.path.abspath(__file__))), 'media/' + str(getUser.id) + '.pdf'), 'rb')
# set the client Data
clientData = {
'type_client': request.data['type_client'],
'type_identity': request.data['type_identity'],
'document_number': request.data['document_number'],
'first_name': request.data['first_name'] if 'first_name' in request.data else None,
'last_name': request.data['last_name'] if 'last_name' in request.data else None,
'social_reason': request.data['social_reason'] if 'social_reason' in request.data else None,
'address': request.data['address'],
'city': request.data['city'],
'email': request.data['email'],
'phone_number': request.data['phone_number'],
'ciiu': request.data['ciiu'],
'broker': request.data['broker'],
'user': getUser.id,
'documents': pdf,
'status': 0,
'income': request.data['income'],
'entered_by': request.user.id
}
# Create a new client
client = ClientSerializer(data=clientData)
this is my model
from django.db import models
# Relations
from apps.misc.models import City, TypeIdentity, TypeCLient, CIIU
from apps.clients.api.models.broker.index import Broker
from apps.authentication.api.models.user.index import User
class Client(models.Model):
id = models.CharField(max_length=255, unique=True,primary_key=True, editable=False)
type_client = models.ForeignKey(TypeCLient, on_delete=models.CASCADE, blank=True)
type_identity = models.ForeignKey(TypeIdentity, on_delete=models.CASCADE, blank=True)
document_number = models.CharField(max_length=255, blank=True, unique=True)
first_name = models.CharField(max_length=255, blank=True, null=True)
last_name = models.CharField(max_length=255, blank=True, null=True)
social_reason = models.CharField(max_length=255, blank=True, null=True)
city = models.ForeignKey(City, on_delete=models.CASCADE, blank=True)
address = models.CharField(max_length=255, blank=True)
email = models.CharField(max_length=255, blank=True, unique=True)
phone_number = models.CharField(max_length=255, blank=True, unique=True)
ciiu = models.ForeignKey(CIIU, on_delete=models.CASCADE, blank=True)
broker = models.ForeignKey(Broker, on_delete=models.CASCADE, blank=True)
user = models.ForeignKey(User, on_delete=models.CASCADE, blank=True)
documents = models.FileField(upload_to='documents/')
income = models.SmallIntegerField(blank=True, default=0)
entered_by = models.ForeignKey(User, on_delete=models.CASCADE, blank=True, null=True, related_name='entered_by')
state = models.BooleanField(default=False)
created_at = models.DateTimeField(auto_now_add=True)
updated_at = models.DateTimeField(null=True, default=None)
class Meta:
db_table = 'clients'
verbose_name = 'clients'
verbose_name_plural = 'clients'
ordering = ['created_at']
as you can see in the documents property of the clientData dict I assign the combined pdf previously, is there any way to solve this?
