Hello, I''m using acts_as_nested_set, and I can create root-nodes and add childs to it. No problem. But what can I do, to delete a certain node and all of it''s children? And of course in a way that it''s consistent, this means that the lft/rgt structure is still consistent. I''m using awesome nested set, but I can''t find a method that is doing this. Or am I blind? At least I couldn''t find it here http://wiki.github.com/collectiveidea/awesome_nested_set/awesome-nested-set-cheat-sheet Thx... -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Keep this in mind as well (an option to the acts_as_nested_set call in your model). * +:dependent+ - behavior for cascading destroy. If set to :destroy, all the # child objects are destroyed alongside this object by calling their destroy # method. If set to :delete_all (default), all the child objects are deleted # without calling their destroy method. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Thx ;-) I can now delete all the childs of a certain node in the database. Is it also possible, to delete certain nodes from a nested set, when the nested set is in an array? After an:>> @project = Project.find(:all)in the console, I have all my projects in @project. I just want to delete now certain nodes (like id 4 and 5 or just node 6). I need this, because I want to create certain views on the nested set. But the destroy should only be done in this variable, not in the database.>> @project.destroy(5)NoMethodError: undefined method `destroy'' for #<Array:0x4eef268> from (irb):11 from :0 Even find does not work:>> @project.find(5)LocalJumpError: no block given from (irb):8:in `find'' from (irb):8:in `each'' from (irb):8:in `find'' from (irb):8 from :0 -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
