Error: a bytes-like object is required, not 'str'

[MrArabboy]

I updated minio package from 7.2.6 to 7.2.8 ,
After file uploaded to FileField and go to obj change page in django admin , raise error a bytes-like object is required, not 'str'

With latest release of minio-py (version 7.2.8) and according to AWS S3 specification object_name has to be a string.

Is there any consideration to encode name any more?

Simply passing object_name as string will fix the issue.

  try:
      u: str = client.presigned_get_object(
          bucket_name=self.bucket,
          object_name=name.encode('utf-8'),
          expires=get_setting("MINIO_URL_EXPIRY_HOURS", timedelta(days=7))  # Default is 7 days
      )
      return u
  except urllib3.exceptions.MaxRetryError:
      raise ConnectionError("Couldn't connect to Minio. Check django_minio_backend parameters in Django-Settings")

I have model:

   class PersonDocument(CreatedUpdatedAbstractModel):
         person = models.ForeignKey(
             "employment.Person", on_delete=models.CASCADE, related_name="documents"
         )
         file = models.FileField(
            storage=MinioBackend(
               bucket_name=settings.DOCUMENT_PRIVATE_BUCKET,
            ),
            upload_to=get_person_document_upload_path,
           )
    
  
def get_person_document_upload_path(instance: Model, filename: str) -> str:
    return os.path.join(
        "person", str(instance.person.id), "documents", str(filename)
    ).replace("\\", "/")`

error cause might be get_person_document_upload_path ?

A workaround is suggested in #51.

However, I agree with @BinDruid that removing the encoding of object_name is the right approach since validation is handled further downstream by the minio-py package.

I've created a PR: #53
