Rails Generate controller aws error missing bucket name

I am attempting to create a Users controller in my ruby on rails project, which I have also configured with heroku and an aws-s3 bucket. I set my .env and my heroku local with the S3_BUCKET, AWS_ACCESS_KEY_ID, and AWS_SECRET_ACCESS_KEY. I also set my initializer/aws.rb file to look like this:

Aws.config.update({
  region: 'us-east-1',
  credentials: Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']),
})

S3_BUCKET = Aws::S3::Resource.new.bucket(ENV['S3_BUCKET'])

I have bundle installed the aws gem like this:

gem 'aws-sdk', '~> 3'

However when I run the command

rails g controller Users new

I get the following error in my terminal:

aws-sdk-s3/bucket.rb:658:in `extract_name': missing required option :name (ArgumentError)

I looked at that file and it is trying to find the S3 bucket name, but I have set that already in .env and heroku local. Is there some other place where this needs to be set? None of the guides I have read mention this error.

Hi please check whether you have specified the right credentials and bucket name. Also, make sure you have provided the right region .Try the below code

s3 = Aws::S3::Resource.new(
      credentials: Aws::Credentials.new(ENV['AWS_ACCESS_KEY_ID'],  ENV['AWS_SECRET_ACCESS_KEY']),
      region: 'us-west-1'
    )

    obj = s3.bucket(ENV['S3_BUCKET']).object('key')

If you want to upload file or something

obj.upload_file(file, acl:'public-read')

This would help you, I have used like this in my project. 1. Create the file aws.rb in your /config/initializers folder. 2. Then copy the below code,

S3Client = Aws::S3::Client.new(
    access_key_id: 'ACCESS_KEY_ID',
    secret_access_key: 'SECRET_ACCESS_KEY',
    region: 'REGION'
)

Thats all, this works. Happy coding :)
