Rails 3 Carrierwave-Fog-S3 error: Expected(200) <=> Actual(404 Not Found)

I'm using Carrerwave 0.5.3 and getting a 404 error on my call to Picture.save in the Create method of my picture controller. Per the instructions in lib/carrierwave/storage/s3.rb I have the following in my initialization file (config/initializers/carrierwave_fog.rb):

CarrierWave.configure do |config|
     config.s3_access_key_id = "xxxxx"
     config.s3_secret_access_key = "xxxxx"
     config.s3_bucket = "mybucket"  #already created in my S3 account
end

In photo_uploader.rb I have:

class PhotoUploader < CarrierWave::Uploader::Base
  include CarrierWave::RMagick
  storage :s3
  def store_dir
    "uploads"  # already created in my s3 account
  end
  def cache_dir
    "uploads/cache"  #already created in my s3 account
  end
end

The exact error:

Excon::Errors::NotFound in PicturesController#create
Expected(200) <=> Actual(404 Not Found)
  request => {:expects=>200}
  response => #<Excon::Response:0x00000104a72448 @body="", @headers={}, @status=404>

I found a slightly similar question her开发者_开发百科e Carrierwave and s3 with heroku error undefined method `fog_credentials=' . But setting things up the way I have it now apparently worked in that case. Unfortunately it didn't for me.

I've put a picture in my bucket and set the permissions to public and can access the picture via a browser. So things on the AWS S3 side seem to be working.

Not sure where to go next. Any ideas?

Well, I slept on this for a night came back the next day and all was good. Not sure why it suddenly started working.

Make sure your file names are sanitized and do not contain invalid characters like spaces or slashes. To sanitize a string you can call the gsub method on it. The following method call will sanitize files for upload to S3, Google Cloud Storage etc.

"Invalid\ file *& | | name.png".gsub(/[^0-9A-z.\-]/, '_')
