How to list all files in an s3 folder using AWS-SDK gem in ruby on rails
Too late answer but better than never.
You can do
s3_bucket.objects.with_prefix('folder_name').collect(&:key)According to official documentation here
Updates:SDK V3
s3 = Aws::S3::Client.newresp = client.list_objects_v2({ bucket: "BucketName", # required prefix: "FolderName", })
You can use this small piece of code for getting list of files for a specific folder.
s3 = Aws::S3::Resource.new(region: 'ap-southeast-1', access_key_id: ENV['AWS_ACCESS_KEY_ID'], secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'] ) data_files = s3.bucket(bucket_name).objects(prefix: 'prefix/', delimiter: 'delimiter').collect(&:key)
https://docs.aws.amazon.com/sdk-for-ruby/v3/api/Aws/S3/Client.html#list_objects_v2-instance_method
SDK V3 has the prefix option for client!
resp = client.list_objects_v2({ bucket: "BucketName", # required prefix: "FolderName", })
