How do I rename image that I uploaded through Django Rest Framework

I have a problem in renaming an uploaded image. Instead of using the original name, I want my uploaded image to have the name model['name'].jpg. I have no problems doing it if I upload it directly from django, but I can't figure out how do I do it if I upload the image through Django Rest Framework.

Here is my model.py:

class Shop(models.Model):
    date = datetime.datetime.now()
    year_now = int(date.strftime('%Y'))

    user = models.ForeignKey(User, on_delete=models.CASCADE)
    name = models.CharField(max_length=20, unique=True)
    slug = models.SlugField(default='')
    logo = models.ImageField(upload_to=rename_and_path)
    industry = models.CharField(max_length= 20, choices=industry_choice)
    business_start = IntegerBoundedField(min_value=1950, max_value=year_now)
    franchise_start = IntegerBoundedField(min_value=1950, max_value=year_now)
    headquarter = models.CharField(max_length=100)
    units = models.IntegerField()
    description = models.TextField()
    joined = models.DateTimeField(auto_now_add=True)

Here is my serializer.py:

class ShopSerializer(serializers.ModelSerializer):
    class Meta:
        model = Shop
        fields= '['name', 'slug', 'logo', 'user', 'industry', 
                'business_start', 'franchise_start', 'headquarter', 
                'units', 'description', 'joined']'

And here is my viewset in views.py:

class ShopViewSet(ModelViewSet):
    queryset = Shop.objects.all()
    serializer_class = ShopSerializer
    lookup_field = 'slug'

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.initial_data['user'] = request.user.id
        serializer.initial_data['slug'] = slugify(request.data['name'])
        serializer.is_valid(raise_exception=True)
        self.perform_create(serializer)
        headers = self.get_success_headers(serializer.data)
        return Response(serializer.data, status=status.HTTP_201_CREATED, headers=headers)

So I would like to know how do I rename the uploaded image in the logo field.

What you want to do is handle the filename modification at model level, so that any uploads from your custom views, django admin and even django-rest-framework will be handled the same.

From your snippets, it looks like you're trying to do this, but I don't see where rename_and_path is defined.

So define the following method above your Shop model

def logo_dir_path(instance, filename):
    extension = filename.split('.')[-1]
    og_filename = filename.split('.')[0]
    new_filename = "shop_%s.%s" % (instance.name, extension)

    return new_filename

Then on your logo field on the model, add the following attribute:

logo = models.ImageField(upload_to=logo_dir_path)
