How can I create private link for files? about django-minio-backend HOT 8 CLOSED

Regarding url method you might just get the URL and if your bucket is private you will get your presigned URL with valid time according to your settings MINIO_URL_EXPIRY_HOURS

from django-minio-backend.

@Podolyan98 you can get the url by accessing .file.url. in your case it would be either photo.file.url or license.file.url.
Using an example from DjangoExampleApplication:

from DjangoExampleApplication.models import PrivateAttachment
pa = PrivateAttachment.objects.first()
print(pa.file.url)
'https://play.min.io/xxxxx/2022-12-17/user/xxxx.png?X-Amz-Algorithm=(........)'

Thanks for stepping in, @a13xg0 !
I'm closing this now. If you're still experiencing problems, @ghorbani-mohammad, please open another issue!

@a13xg0 Hello. Through the Django admin panel the URL method works, but through the my API I only see the direct path:

GET http://localhost:8888/api/users/aa658d18-e0b0-4537-8cb6-7e3c2251c197

Response:

{
"id": "aa658d18-e0b0-4537-8cb6-7e3c2251c197",
"photo": "aa658d18-e0b0-4537-8cb6-7e3c2251c197/2022-12-16_11-34-01.png",
"license": "aa658d18-e0b0-4537-8cb6-7e3c2251c197/file.md",

How to get pre-signed url?

from django-minio-backend.

@Podolyan98 Hi! My first guess looking at your response, is that you just got the value from your DB, not the resolved URL thru the minio's backend. You may check the order of middleware in your config.

@a13xg0 How can I get the resolved url through the minio backend?

models.py:

photo = models.ImageField(storage=MinioBackend(bucket_name='django-backend-users-private', replace_existing=True), upload_to=user_directory_path, null=True, blank=True)
license = models.FileField(storage=MinioBackend(bucket_name='django-backend-users-private', replace_existing=True), upload_to=user_directory_path, null=True, blank=True)

settings.py:

MINIO_ENDPOINT = 'docs.domain.com'
MINIO_EXTERNAL_ENDPOINT = 'docs.domain.com'
MINIO_EXTERNAL_ENDPOINT_USE_HTTPS = True 
MINIO_ACCESS_KEY = '123'
MINIO_SECRET_KEY = '123'
MINIO_USE_HTTPS = True
MINIO_URL_EXPIRY_HOURS = timedelta(days=1)
MINIO_PRIVATE_BUCKETS = [
    'django-backend-dev-private',
    'django-backend-users-private',
]
MINIO_POLICY_HOOKS: List[Tuple[str, dict]] = []
MINIO_BUCKET_CHECK_ON_SAVE = True

from django-minio-backend.

@theriverman In models.py I specified the method that is used to get the private link in the APIView.

models.py:

photo_0 = models.ImageField(storage=MinioBackend(bucket_name='django-backend-users-private', replace_existing=True), upload_to=User_directory_path('photo_0'), null=True, blank=True)

@property
def photo_0_url(self):
    if self.photo_0 and hasattr(self.photo_0, 'url'):
        return self.photo_0.url

views.py:

def get(self, request, pk):
    try:
        queryset = User.objects.filter(id=pk).first()
        user_dict = queryset.values().first()
        # overwrite file path using resolved URL thru the minio's backend
        user_dict['photo_0'] = user.photo_0_url
        return Response(user_dict, status=status.HTTP_200_OK) 
    except Exception as error:
        logger.error(traceback.format_exc())
        raise APIException(error)

It works. The problem is that there are a lot of fields like ImageField and FileField, I need to overwrite each field in views.py, for example user_dict['photo_0'] = user.photo_0_url. Is it possible to call similar methods automatically for every ImageField or FileField?

By the way, when creating or updating records with ImageField and FileField, private links are automatically generated.

@Podolyan98 I don't see how your question is related to this third-party package.
What you're asking is more of a generic Django question which should not be discussed here.
