Django在上传到Amazon S3存储桶之前更改图像名称

Question

I am using Django-1.7 and have a field of type ImageField in a model to store the image link to the AWS S3 bucket

cover_image = models.ImageField(upload_to='s3_bucket_name/', null=True, blank=True)

In the settins.py file, I have

MEDIA_ROOT = 'url_to_aws_s3_bucket'
MEDIA_URL = 'url_to_aws_s3_bucket'
DEFAULT_FILE_STORAGE = 'storages.backends.s3boto.S3BotoStorage'
AWS_STORAGE_BUCKET_NAME = 'bucket_name'
AWS_ACCESS_KEY_ID = 's3_access_key'
AWS_SECRET_ACCESS_KEY = 's3_secret_key'

The problem is when I upload an image with @ character in its name, Django removes all instances of @ before uploading the image to Amazon S3 bucket.

How do I keep the name of the image file intact?

Answer 1

You can try to inherit from S3BotoStorage and redefine get_available_name method:

class MyS3BotoStorage(S3BotoStorage):
    def get_available_name(self, name):
        return name

Answer 2

Instead of passing a string as upload_to='s3_bucket_name/' , I passed the function

def change_filename(instance, filename):
    return 'bucket_name/' + filename

# inside the model class
cover_image = models.ImageField(upload_to=change_filename, null=True, blank=True)

and now it works fine.
