Amazon AWS IAM Group Policy for a Single S3 Bucket

It is stupid how difficult it is to allow a group (or a user) access to only one bucket, or a series of select buckets. Here is the policy allowing a group to access a bucket called MY-BUCKET

{
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "arn:aws:s3:::MY-BUCKET"
    },
    {
      "Effect": "Allow",
      "Action": "s3:*",
      "Resource": "arn:aws:s3:::MY-BUCKET/*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:ListAllMyBuckets"
      ],
      "Resource": "*"
    }
  ]

Notice, there is no way to only list this bucket in the S3 console. All buckets under the account WILL be listed, but if any are clicked, a message will notify the user they do not have permissions to access\mutate the given bucket.

ActionView::Template::Error in Unit Tests (Rails 3 + Devise)

So I’m resuming development and trying to create coverage for existing code before attempting actual TDD and I get this in my unit tests:

ActionView::Template::Error: Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true

These are unit tests! This is madness! Full error:

AdviceTest:
    ERROR test: Advice should belong to user.  (1.53s) 
          ActionView::Template::Error: Missing host to link to! Please provide the :host parameter, set default_url_options[:host], or set :only_path to true
          /home/denis/.rvm/gems/ruby-1.9.2-p290/gems/actionpack-3.1.0/lib/action_dispatch/http/url.rb:25:in `url_for'

The above problem creeps up when you’ve forgot to set mailer settings for Devise in your test environment.

open up config/environments/test.rb and a line to the likes of:

config.action_mailer.default_url_options = { :host => 'localhost:3000' }
