#Botta- How about something like this
from django.db import models
Create your models here.
class MyFile(models.Model):
file = models.FileField(blank=False, null=False,upload_to='images/')
description = models.CharField(null=True,max_length=255)
uploaded_at = models.DateTimeField(auto_now_add=True)
class Meta:
verbose_name_plural = 'MyFiles'
class MyFileView(APIView):
# MultiPartParser AND FormParser
# https://www.django-rest-framework.org/api-guide/parsers/#multipartparser
# "You will typically want to use both FormParser and MultiPartParser
# together in order to fully support HTML form data."
parser_classes = (MultiPartParser, FormParser)
def post(self, request, *args, **kwargs):
file_serializer = MyFileSerializer(data=request.data)
if file_serializer.is_valid():
file_serializer.save()
return Response(file_serializer.data, status=status.HTTP_201_CREATED)
else:
return Response(file_serializer.errors, status=status.HTTP_400_BAD_REQUEST)
serializers.py
from rest_framework import serializers
from .models import MyFile
class MyFileSerializer(serializers.ModelSerializer):
class Meta:
model = MyFile
fields = ('file', 'description', 'uploaded_at')

#Stacy Hi. I made the changes, but it didn't work. I would like the fields in the CSV file to go automatically to my models and to the REST API. I would like to import my CSV data when uploading the file. Thanks.
models.py
from django.db import models
class MyFile(models.Model):
file = models.FileField(blank=False, null=False,upload_to='images/')
description = models.CharField(null=True,max_length=255)
uploaded_at = models.DateTimeField(auto_now_add=True)
name = models.CharField(max_length=150)
sex = models.CharField(max_length=150)
age = models.CharField(max_length=50)
height = models.CharField(max_length=150)
def __str__(self):
return self.description
class Meta:
verbose_name_plural = 'MyFiles'
serializers.py
from rest_framework import serializers
from .models import MyFile
class MyFileSerializer(serializers.ModelSerializer):
class Meta:
model = MyFile
fields = ("file", "description", "uploaded_at", "name", "sex", "age", "height",)

#Stacy- Hello. I was able to upload the csv file and pass it to my API as .CSV, however, I would like all fields in my CSV file to be transferred to API Rest. For example ID, Name, Age and Profile. It's possible? Thank you. Thank you.
