I used django docker and aws s3 bucket for my project. I configure my settings file for my bucket and it is working but i got an error while uploading media files "expected string or bytes-like object" and docker log error if not VALID_BUCKET.search(bucket) and not VALID_S3_ARN.search(bucket). I used django forms and function based view.

models.py

def user_directory_path(instance, filename):
    tenant = connection.get_tenant()
    return 'profile_photos/{0}/{1}'.format(tenant, filename)

class UserProfilePhoto(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    profilephoto = models.ImageField(blank=True,default="profile_photos/profilephoto.png",upload_to=user_directory_path )

views.py

I am trying to upload media files to my s3 bucket using django-forms and boto

I followed https://github.com/veryacademy/YT-Django-Media-Static-AWS-S3 tutorial

CodePudding user response：

Problem seems to be about your .env file. You cannot connect to your bucket since your key and id is not read by the program.

You can also install dotenv package for managing your env files.
