Hello experts, I am trying to user attachement_fu plugin on sinatra.. When I''m posting request on sinatra.. including file params then in log it showing posted params[:file] format in hash type.. like {"uploaded_data"=> {:filename=>"user.JPG", :type=>"image/jpeg", :name=>"custom_thumbnail[uploaded_data]", :tempfile=> #<File:C:/DOCUME~1/Nishant/LOCALS~1/Temp/RackMultipart4072-15639>, :head=> "Content-Disposition: form-data; name=\"custom_thumbnail[uploaded_data]\"; filename=\"user.JPG\"\r\nContent-Type: image/jpeg\r\n"}} instead of as attachement_fu needs it request file params as like {"uploaded_data"=> #<ActionDispatch::Http::UploadedFile:0x1434 @content_type="image/jpeg", @headers "Content-Disposition: form-data; name=\"custom_thumbnail[uploaded_data]\"; filename=\"user.JPG\"\r\nContent-Type: image/jpeg\r\n", @original_filename="user.JPG", @tempfile #<File:C:/DOCUME~1/Nishant/LOCALS~1/Temp/RackMultipart4072-15640>>} Due to above(first one) has type format attachement_fu is not supporting.. it showing errors like undefined method ''content_type'' and all other.... Any ideas..? on how to get this to change/access params format as normal format(like action_controller params)?
