About File Comparison in Default Storage
Here's a function to compare two files in default_storage whether their content is the same:
def storage_file_compare(file1_path, file2_path, chunk_size=8192):
import hashlib
from django.core.files.storage import default_storage
def calculate_hash(file_path):
sha256 = hashlib.sha256()
with default_storage.open(file_path, "rb") as f:
for chunk in iter(lambda: f.read(chunk_size), b""):
sha256.update(chunk)
return sha256.hexdigest()
hash1 = calculate_hash(file1_path)
hash2 = calculate_hash(file2_path)
return hash1 == hash2
Then you can compare the files:
>>> storage_file_compare("gallery/cat.png", "gallery/cat-copy.png")
True
It works with boto3 and object storage, such as AWS S3 or DigitalOcean Spaces.
