Django 4.0: Problems with FileField Not Saving to Custom Storage Backend

I've looked through the documentation and I'm still confused about I keep running into I've looked through the documentation and I'm still confused about I'm having trouble with a `FileField` in my Django 4.0 application that is supposed to save uploaded files to a custom storage backend, but instead, it's not storing the files at all. I have implemented a custom storage class that inherits from `FileSystemStorage`, but the `save` method doesn't seem to be called when I upload a file through a form. Hereโ€™s a snippet of my storage class: ```python from django.core.files.storage import FileSystemStorage class CustomStorage(FileSystemStorage): def get_available_name(self, name, max_length=None): # Custom logic for file name handling return super().get_available_name(name, max_length) ``` In my model, I have the following: ```python from django.db import models class MyModel(models.Model): file = models.FileField(storage=CustomStorage()) ``` When I attempt to upload a file through a form in my admin panel, I get no behavior messages, but the file simply isnโ€™t appearing in the specified directory. Iโ€™ve ensured that the directory has the correct permissions and is accessible from the Django application. Iโ€™ve also added some print statements in the `save` method of my `CustomStorage`, but these are not being executed, indicating that the method isn't being triggered at all. I tried explicitly calling the `save` method in my view like this: ```python if request.method == 'POST': my_model_instance = MyModel() my_model_instance.file.save(request.FILES['file'].name, request.FILES['file']) my_model_instance.save() ``` But I'm still not seeing any files being saved. I've explored the documentation and also checked if I need to specify a custom `UPLOAD_TO` path, but nothing seems to resolve the scenario. What could be causing the `FileField` to bypass the storage functionality? Any insights would be appreciated! For context: I'm using Python on Windows. This is my first time working with Python 3.11. This is part of a larger microservice I'm building.
