How to save CloudinaryField in a folder named by the user-CodePudding

I am trying to upload an image to cloudinary with a CloudinaryField in my models.py. I want the image to be uploaded to a folder in cloudinary named in this format : users/<username>/pictures/profile. so far I leart I can set folder and public_id of the field, but I cannot name it dynamically. for example I can pass a function in upload_to key in ImageField to create the image wherever i want. is there any way to do this with CloudinaryField ?? thanks ahead!

In using the CloudinaryField, it can accept parameters as defined in the Upload API documentation. The folder name (or prefix) can be provided as folder=some/target/foldername, while using both use_filename=True and unique_filename=False will set the public_id to use the filename of the asset. Otherwise, using a dynamic value can also be set as public_id=some-dynamic-custom-value.

For example:

           image = CloudinaryField('image',
                        public_id='dynamicpublicid',
                        use_filename=True,
                        unique_filename=False,
                        folder='users/username/pictures/profile')

The only solution I was able to come up with, based on this question (which suggested answer did not work) is to override pre_save like so:

class CloudinaryField(CloudinaryField):
def upload_options(self, instance):
    return {
        'folder': "users/{0}/cats/{1}".format(instance.owner.username,instance.name),
        'public_id': 'profile',
        'overwrite': True,
        'resource_type': 'image',
        'quality': 'auto:eco',
    }
def pre_save(self, model_instance, add):
    self.options =  dict(list(self.options.items())   list(self.upload_options(model_instance).items())) 
    super().pre_save(model_instance, add)

I don't know if it's a good solution, but it's a working one...
