Missing requirement when using carrierwave and fog

Question

I got this error Missing required arguments: aws_access_key_id, aws_secret_access_key. That seems weird because I already added carrierwave.rb in initializers folder. The access/secret key works perfectly when I use aws-sdk

CarrierWave.configure do |config|
  config.fog_credentials = {
    provider: "AWS",
    aws_access_key_id: ENV["PUB-KEY"],
    aws_secret_access_key: ENV["SEC-KEY"]
  }
  config.fog_directory = ENV["mybucket"] 
end

Answer 1

Here's what my working one looks like:

CarrierWave.configure do |config|
  config.fog_credentials = {
    :provider               => 'AWS',
    :aws_access_key_id      => ENV['S3_KEY'],
    :aws_secret_access_key  => ENV['S3_SECRET'],
    :region                 => 'us-east-1'
  }
  config.fog_directory  = ENV['S3_BUCKET']
end

For production, I added the keys S3_KEY, S3_SECRET and S3_BUCKET. For development and testing, I used an initializer that is in a .gitignore file:

# .gitignore
/config/initializers/app_environment_variables.rb

and in the initializer

# config/initializers/app_environment_variables.rb

ENV['S3_KEY'] = "********************"
ENV['S3_SECRET'] = "**************************..."
ENV['S3_BUCKET'] = "**********-dev"

Production and development configurations are different. You need to put AWS keys in development too.

I just copied AWS keys from

config/environments/production.rb

to

config/environments/development.rb

And everything worked fine.
