Customize AWS File Storage in cookiecutter.storagebackend using boto3

This guide will walk you through the steps to customize AWS file storage in cookiecutter.storagebackend using boto3.

Step 1: Install Boto3

First, make sure you have boto3 installed in your project environment:

pip install boto3

Step 2: Configure AWS Credentials

Next, configure your AWS credentials in your environment variables or AWS configuration files.

Step 3: Customize cookiecutter.storagebackend

Now, customize cookiecutter.storagebackend to use AWS S3 file storage by modifying the backend.py file as follows:

import boto3
from django.core.files.storage import get_storage_class

s3 = boto3.resource('s3')
storage_class = get_storage_class('storages.backends.s3boto3.S3Boto3Storage')

class CustomS3Storage(storage_class):
    def __init__(self, *args, **kwargs):
        kwargs['bucket'] = 'my-bucket-name'  # Replace with your S3 bucket name
        super().__init__(*args, **kwargs)

    def _save(self, name, content):
        """
        Save a file to AWS S3.
        """
        self._create_bucket_if_not_exists()
        return super()._save(name, content)

    def _create_bucket_if_not_exists(self):
        """
        Create an S3 bucket if it does not already exist.
        """
        if self.bucket_name not in [bucket.name for bucket in s3.buckets.all()]:
            s3.create_bucket(Bucket=self.bucket_name)

DEFAULT_FILE_STORAGE = 'path.to.CustomS3Storage'

Step 4: Test the Custom Storage Backend

Finally, test the custom storage backend by uploading a file to S3 using Django’s default_storage:

from django.core.files.storage import default_storage

file = open('/path/to/file.jpg', 'rb')
default_storage.save('file.jpg', file)
