Question

I am having problems uploading images to Amazon S3. I have installed the paperclip gem and the gem ‘aws-s3’. My Amazon S3 server is the europen: http://s3-eu-west-1.amazonaws.com

When I submit my form the form is rendered again because the photographer is not saved. And I can see that nothing is uploaded to the cloud. And I get the message “Image ok” in view.

My controller:

def savenew
    @photographer = Photographer.create(params[:photographers]) 
    @photographer.sort_order = Photographer.count + 1

    if @photographer.save   
      redirect_to :action => 'list', :id => params[:id] 
    else    
      render 'create', :id => params[:id]             
    end                                 
end     

My model:

    attr_accessor :flv_file_size, :flv_updated_at, :flv_content_type, :image_file_size, :image_updated_at, :image_content_type,
    :quicktime_file_size, :quicktime_updated_at, :quicktime_content_type

  has_attached_file :image,
    :storage => :s3,
    :bucket => 'mybucket',
    :path => "/photographer/image/:id/:filename",
    :s3_credentials => {
      :access_key_id => 'mykey',
      :secret_access_key => 'mykey'
    }

  has_attached_file :flv,
    :storage => :s3,
    :bucket => 'mybucket',
    :path => "/photographer/flv/:id/:filename",
    :s3_credentials => {
      :access_key_id => 'mykey',
      :secret_access_key => 'mykey'
    }

      has_attached_file :quicktime,
    :storage => :s3,
    :bucket => 'mybucket',
    :path => "/photographer/quicktime/:id/:filename",
    :s3_credentials => {
      :access_key_id => 'mykey',
      :secret_access_key => 'mykey'
    }

My create page:

<h2>Movie</h2>

Answer 1

The AWS-S3 gem works fine with European S3 buckets.

If you add this to the enviroment.rb:

AWS::S3::DEFAULT_HOST.replace "s3-eu-west-1.amazonaws.com"
