ruby on rails - Carrierwave - development upload issues after adding S3/Fog for production -

i got production rails 3 app setup use fog/s3 storage while running on heroku. in process, made few changes /config/initializers/carrierwave.rb. here's looks like:

carrierwave.configure |config|    if rails.env.test? || rails.env.development?     config.root = rails.root     config.storage = :file   else     config.storage = :fog     config.fog_credentials = {     :provider               => 'aws',                        # required     :aws_access_key_id      => env['my_id'],                        # required     :aws_secret_access_key  => env['my_key']                        # required     }       config.fog_directory  = 'my-app'                     # required       config.fog_public     = false                                   # optional, defaults true       #config.fog_attributes = {'cache-control'=>'max-age=315576000'}  # optional, defaults {}   end end 

here's image_uploader:

class imageuploader < carrierwave::uploader::base   def store_dir     "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"   end end 

uploads working fine in production. files being uploaded correct destination in development, error when viewing uploaded image:

actioncontroller::routingerror (no route matches [get] "/uploads/vendor/image/24/storeb.png"): 

i'm unsure of how fix this. missing in uploader? please? let me know if need more info. in advance!

edit code example throws error:

<% @stores.each |s| %>         <div class="row">                 <div class= "col-xs-9 horz-cent">                         <%= link_to image_tag("#{s.vendor.image}"), user_show_store_path(s) %>                 </div>         </div> <% end %> 

set config.root below

 config.root = rails.root.join('public') 

currently files getting uploaded in rails.root directory non accessible browser not in public directory.
