Hello
I have a problem in the creation of a thumbnail for an uploaded image (with Attachment Fu) For resizing images, i've installed ImageScience, following steps of this article (on Mac 10.4.0 : freeimage installed with MacPort, ImageScience 1.1.3 gem installed (aith its dependencies), AttachmentFu plugin installed)
When resizing the image, i get the following error stack at the screen (and all messages of validations for my model class)
/usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/validations.rb:764:in `save_without_transactions!' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/transactions.rb:133:in `save!' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/connection_adapters/abstract/database_statements.rb: 59:in `transaction' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/transactions.rb:95:in `transaction' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/transactions.rb:121:in `transaction' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/transactions.rb:133:in `save!' vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu.rb:215:in `create_or_update_thumbnail' /usr/local/lib/ruby/gems/1.8/gems/activesupport-1.4.2/lib/ active_support/core_ext/object/misc.rb:23:in `returning' vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu.rb:207:in `create_or_update_thumbnail' vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu.rb:367:in `after_process_attachment' vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu.rb:367:in `each' vendor/plugins/attachment_fu/lib/technoweenie/attachment_fu.rb:367:in `after_process_attachment' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/callbacks.rb:333:in `send' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/callbacks.rb:333:in `callback' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/callbacks.rb:330:in `each' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/callbacks.rb:330:in `callback' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/callbacks.rb:243:in `create_or_update' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/base.rb:1545:in `save_without_validation' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/validations.rb:752:in `save_without_transactions' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/transactions.rb:129:in `save' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/connection_adapters/abstract/database_statements.rb: 59:in `transaction' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/transactions.rb:95:in `transaction' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/transactions.rb:121:in `transaction' /usr/local/lib/ruby/gems/1.8/gems/activerecord-1.15.3/lib/ active_record/transactions.rb:129:in `save' app/controllers/player_controller.rb:35:in `signup'
Has anyone already encountered this kind of error?
