Paperclip::AdapterRegistry::NoHandlerError - ruby-on-rails-4

Question

I recently set up direct image uploads to my Amazon S3 bucket following the tutorial created my Heroku here.
When I upload the file, it is successfully sent to my S3 bucket, but when I try to save the image I get the following error
Paperclip::AdapterRegistry::NoHandlerError at /photos
No handler found for "//mys3bucket.s3.amazonaws.com/uploads/3452345aef45845blabla/the file name.fileExtension"
Here is the form in my view:
<%= bootstrap_form_for #photo, html: { multipart: true, class: 'directUpload', data: { 'form-data' => (#s3_direct_post.fields), 'url' => #s3_direct_post.url, 'host' => URI.parse(#s3_direct_post.url).host } } do |f| %>
<p>
<%= f.text_field :title %>
</p>
<p>
<%= f.file_field :image %>
</p>
<%= f.submit 'Upload', class: 'btn btn-success' %>
<% end %>
Here is my create method in my controller:
def create
if can? :create, Photo
#photo = Photo.new(photo_params)
if #photo.save
redirect_to photos_path
else
render 'new'
end
else
redirect_to root_path
end
end
private
def photo_params
params.require(:photo).permit(:image, :title)
end
def set_s3_direct_post
#s3_direct_post = S3_BUCKET.presigned_post(key: "uploads/#{SecureRandom.uuid}/${filename}", success_action_status: '201', acl: 'public-read')
end
Here is my model:
class Photo < ActiveRecord::Base
has_attached_file :image
belongs_to :article
validates :title, presence: true
validates :image,
attachment_content_type: { content_type: /\Aimage\/.*\Z/ },
attachment_size: { less_than: 5.megabytes }
end
Here is my entire repository
I understand that for some reason Paperclip does not know how to handle the URL but I have no idea how to fix this. I tried adding a new column to my Photos table in my database and just saving the URL to that column. That worked perfectly of course because Paperclip was not involved. Any help would be much appreciated.

Answer 1

Have you tried to add s3_host_name to your configuration?
Like:
config.paperclip_defaults = {
storage: :s3,
s3_host_name: "s3-ap-northeast-1.amazonaws.com", #example
s3_region: ENV['AWS_REGION'],
s3_credentials: {
bucket: ENV['S3_BUCKET_NAME'],
access_key_id: ENV['AWS_ACCESS_KEY_ID'],
secret_access_key: ENV['AWS_SECRET_ACCESS_KEY']
}
}

Answer 2

I would appear that I have found the answer. I don't think it's the best way of doing it because I am essentially bypassing Paperclip but at this point whatever.
I changed my model and database to just accept a url string instead of an attachment with the following code:
/models/photo.rb
class Photo < ActiveRecord::Base
belongs_to :article
validates :title, presence: true
validates :image_url, presence: true, length: { minimum: 5 }
end
First Migration
class RemoveAttatchedImageFromPhotos < ActiveRecord::Migration
def change
remove_column :photos, :attached_image_file_name
remove_column :photos, :attached_image_content_type
remove_column :photos, :attached_image_file_size
remove_column :photos, :attached_image_updated_at
end
end
Second Migration
class AddImageUrlToPhoto2 < ActiveRecord::Migration
def change
add_column :photos, :image_url, :string
end
end
