Kohana transactions on multiple tables


Tag : php , By : Keniwan

should help you out Kohana 3 apparently has transaction methods, although they do not appear to be documented. See this link
Transactions are database-level, so anything you do between a start and a commit is part of the transaction, no matter how many tables are involved.

Rails updating object creating two database transactions

seems to work fine The :create_salesforce_loan_application is being called twice because the object is updated twice in the process, maybe by other callback or gem such as Paperclip.
A better approach to this would be to use after_save instead of after_commit, checking if :status attribute changed.
class LoanApplication < ActiveRecord:Base
  after_save :create_salesforce_loan_application, on: :update

  def create_salesforce_loan_application
    if status_changed? && status == 'active'
      puts "create salesforce function running"       
      # Updating business column
      business.update_column(:state, 1)
    end
  end
end

updating multiple database tables in one PUT/PATCH

will help you Ok, I have found a solution, apparently it was super simple but if someone has similar confusion here's the answer:
Just get the user with username which is set in nested object like this.
for buy_data in buy:
    buy_history_s = BuyHistory(**buy_data)
    try:
        user = User.objects.get(username=buy_history_s.username)
    except errors.DoesNotExist:
        raise exceptions.AuthenticationFailed()
    if buy_history_s.time is None:
        buy_history_s.time = datetime.datetime.now()
    updated_instance.buy_history.append(buy_history_s)
    user.buy_history.append(buy_history_s)
    user.save()
