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"
lab_id: "81"
updated_at: 2010-03-21 22:16:06
id: "184"
lab_desc_id: "6"
value: "29"
attributes_cache: {}
changed_attributes: {}
errors: !ruby/object:ActiveRecord::Errors
base: *id001
errors: {}
And if I remove the "raise", the controller throws a "can't modify
frozen hash" error.
Any idea how I can remove records from the hash prior to saving?
TIA,
Craig
