• How do I present a RichFaces tree with a specific node already expanded

  - by Brummo

  I have a JSF page that displays a RichFaces Treeview, from a TreeNodeImpl model generated in the backing bean. Now I want the page to display initially with a specific node expanded / selected. Preferrably this expansion should be controlled from the backing bean (no javascript wizardry) The whole tree has been generated at the time of initialization of the backing bean Is this possible? I have seen mentioning of TreeState, is that the way to go?

• Paperclip: delete attachments and "can't convert nil into String" error

  - by snitko

  I'm using Paperclip and here's what I do in the model to delete attachments: def before_save self.avatar = nil if @delete_avatar == 1.to_s end Works fine unless @delete_avatar flag is set when the user is actually uploading the image (so the model receives both params[:user][:avatar] and params[:user][:delete_avatar]. This results in the following error: TypeError: can't convert nil into String from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/storage.rb:40:in `dirname' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/storage.rb:40:in `flush_writes' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/storage.rb:38:in `each' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/storage.rb:38:in `flush_writes' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/attachment.rb:144:in `save' from /Work/project/src/vendor/plugins/paperclip/lib/paperclip/attachment.rb:162:in `destroy' from /Work/project/src/app/models/user.rb:72:in `before_save' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/callbacks.rb:347:in `send' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/callbacks.rb:347:in `callback' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/callbacks.rb:249:in `create_or_update' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:2538:in `save_without_validation' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/validations.rb:1078:in `save_without_dirty' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/dirty.rb:79:in `save_without_transactions' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:229:in `send' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:229:in `with_transaction_returning_status' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/connection_adapters/abstract/database_statements.rb:136:in `transaction' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:182:in `transaction' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:228:in `with_transaction_returning_status' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:196:in `save' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:208:in `rollback_active_record_state!' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/transactions.rb:196:in `save' from /usr/lib/ruby/gems/1.8/gems/activerecord-2.3.5/lib/active_record/base.rb:723:in `create' I assume it has something to do with the avatar.dirty? value because when it certainly is true when this happens. The question is, how do I totally reset the thing if there are changes to be saved and abort avatar upload when the flag is set?

  - by Sean Johnson

  I'm working with a client on a rails project that wants to have a user model with 'stub' accounts that are created by an administrator, but that can later be claimed by the actual user, with authentication enabled on that user once the owner has claimed it. Was wondering if anyone has done this before, and what the best approach would be. We're currently using Authlogic to handle authentication.

• What should be the considerations for choosing SQL/NoSQL?

  Target application is a medium-sized website built to support several hundred-thousand users an hour, with an option to scale above that. Data model is rather simple, and caching potential is pretty high (~10:1 ratio of read to edit actions). What should be the considerations when coming to choose between a relational, SQL-based datastore to a NoSQL option (such as HBase and Cassandra)?

• What's the right way to display a DBIx::Class ResultSet in my Catalyst project that uses Template To

  - by Thelema

  Given a DBIx::Class resultset, for example: my $rs = $c->model("DB::Card")->search({family_name => "Smith"}); the tutorials I've read use the stash to pass an arrayref of rows: $c->stash->{cards} = [$rs->all]; This results in the query getting executed at this point, and the resulting objects stuffed into the stash, so they can be used in TemplateToolkit as: [% FOREACH card IN cards %] [% card.given_name %] [% card.family_name %] [%END%] Is there a proper way to have TT iterate over the rows as they get fetched from the DB?

• Resources on technical GUI design

  - by Thomas Lötzer

  Hi, I am looking for recommendations on resources (both books and websites) on designing GUI applications. By designing I mean the technical design (when and how to use data binding, when should MVC/MVP be used, what functionality should go into the model, the view, the controller/presenter, how can different parts of the UI best be kept in sync ...), not the screen design of which button goes where or how the interaction with the user should take place. Thanks, Thomas

• Qt QTableView and horizontalHeader()->restoreState()

  - by cheez

  I can't narrow down this bug, however I seem to have the following problem: - saveState() of a horizontalHeader() - restart app - Modify model so that it has one less column - restoreState() - Now, for some reason, the state of the headerview is totally messed up. I cannot show or hide any new columns, nor can I ever get a reasonable state back I know, this is not very descriptive but I'm hoping others have had this problem before.
