我正在使用CarrierWave Direct和Sidekiq在後臺將圖像上傳到Amazon S3。圖像正在按預期上傳,但我似乎無法將圖像記錄添加到數據庫。當我提出錯誤時,我得到filename can't be blank
。無法使用CarrierWave Direct將圖像保存到數據庫
下面是相關的代碼:
應用程序/上傳/ image_uploader.rb
class ImageUploader < CarrierWave::Uploader::Base
include CarrierWaveDirect::Uploader
include CarrierWave::MimeTypes
process :set_content_type
end
應用程序/控制器/管理/ images_controller.rb
def index
@uploader = Image.new.filename
@uploader.success_action_redirect = new_admin_project_image_url(@project)
render "new"
end
def new
@image = Image.new
@image.filename = params[:key]
@image.imageable = @project
unless @image.save
raise @image.errors.to_yaml
end
end
應用/models/image.rb
class Image < ActiveRecord::Base
attr_accessible :imageable_id, :imageable_type, :filename
validates :filename, presence: true
validates :imageable_id, presence: true
validates :imageable_type, presence: true
belongs_to :imageable, polymorphic: true
mount_uploader :filename, ImageUploader
end
應用程序/視圖/管理/圖片/ new.html.erb
<%= direct_upload_form_for @uploader do |f| %>
<p><%= f.file_field :filename %></p>
<p><%= f.submit "Upload Image" %></p>
<% end %>
