Ruby on rails Spree and S3 - ruby-on-rails

Question

I am having a difficult time connecting Amazon S3 buckets to a e-commerce spree application. I have added the necessary code to the initializer/spree.rb and set the necessary environment variables. This is the code inside my spree.rb
# Configure Solidus Preferences
# See http://docs.solidus.io/Spree/AppConfiguration.html for details
Spree.config do |config|
# Without this preferences are loaded and persisted to the database. This
# changes them to be stored in memory.
# This will be the default in a future version.
config.use_static_preferences!
# Core:
# Default currency for new sites
config.currency = "USD"
# from address for transactional emails
config.mails_from = "expressmobiletechs#gmail.com"
# Uncomment to stop tracking inventory levels in the application
# config.track_inventory_levels = false
# When set, product caches are only invalidated when they fall below or rise
# above the inventory_cache_threshold that is set. Default is to invalidate cache on
# any inventory changes.
# config.inventory_cache_threshold = 3
# Frontend:
config.logo = "logo.jpg"
config.admin_interface_logo = "logo.jpg"
# Template to use when rendering layout
# config.layout = "spree/layouts/spree_application"
# Admin:
# Custom logo for the admin
# config.admin_interface_logo = "logo/solidus_logo.png"
# Gateway credentials can be configured statically here and referenced from
# the admin. They can also be fully configured from the admin.
#
# config.static_model_preferences.add(
# Spree::Gateway::StripeGateway,
# 'stripe_env_credentials',
# secret_key: ENV['STRIPE_SECRET_KEY'],
# publishable_key: ENV['STRIPE_PUBLISHABLE_KEY'],
# server: Rails.env.production? ? 'production' : 'test',
# test_mode: !Rails.env.production?
# )
end
Spree::Frontend::Config.configure do |config|
config.use_static_preferences!
config.locale = 'en'
end
Spree::Backend::Config.configure do |config|
config.use_static_preferences!
config.locale = 'en'
end
Spree::Api::Config.configure do |config|
config.use_static_preferences!
config.requires_authentication = true
end
Spree.user_class = "Spree::LegacyUser"
attachment_config = {
s3_credentials: {
access_key_id: ENV['AWS_ACCESS_KEY_ID'],
secret_access_key: ENV['AWS_SECRET_ACCESS_KEY'],
bucket: ENV['S3_BUCKET_NAME']
},
storage: :s3,
s3_headers: { "Cache-Control" => "max-age=31557600" },
s3_protocol: "https",
bucket: ENV['S3_BUCKET_NAME'],
url: ":s3_domain_url",
styles: {
mini: "48x48>",
small: "100x100>",
product: "240x240>",
large: "600x600>"
},
path: "/spree/:class/:id/:style/:basename.:extension",
default_url: "/spree/:class/:id/:style/:basename.:extension",
default_style: "product"
}
attachment_config.each do |key, value|
Spree::Image.attachment_definitions[:attachment][key.to_sym] = value
end
I am trying to get my spree stores image uploading for products to work with s3. No other discussion on stack has been able to help me.
