Validation method vs. After Save & Rollback
...if I have 10 owners each with 10% of the company and I update one
of the owners and set their share to 11%, I should be given a warning
message.
This is what I have done in my Owner model:
def more_than_100_given_away?
# => find the total share
company = Company.find(company_id)
company_total_share = company.total_share # => This is summing the
old value
if changed?
if changes["share"] # => Changes to a model are stored in the
changes array on the instance, the array has 2 value ["from_value",
"to_value"]
old_value = changes["share"]...
