Hi, I''m having some problem with getting collection_select to return the current value when editing a record. According to everything I''ve seen, there was an issue but it''s been fixed, but I can''t figure out why it isn''t returning the current value as a selected option. I''ve checked the table structures, and both the call_driver.product_line_id

Hi, I''ve got a problem on which I''ve spent many hours, and I can''t get a clue on what is happening... I hope someone here will be able to help me.

Everything''s working OK individually: I can create a comment on a Diagram, bookmark it, and so on. Now,

I''d like to delete some records before saving them. I ran this experiment: before_save :prune_lab_datas def prune_lab_datas lab_datas.each do |lab_data| lab_data.destroy end raise lab_datas.to_yaml end But nothing seems to be deleted in the hash: --- - &id001 !ruby/object:LabData attributes: created_at: 2010-03-21 22:16:06 unit_id: "3"

I am after a nice way to disable (not destroy, delete nor nullify) all associated records. I''m a hoarder, I don''t want to get rid of anything but I want to stop records being visible. I have a disabled boolean in my tables and if I disable the top record in the association (say the association is 5-6 levels deep), I would like to cleanly disable its children. I''ve
