=======
In this module, you will learn to modify existing business flows.
Create a small module that depends on the module sale. The module should add a
double validation process on sales orders: the sales user first confirms their
sales order, then a sales manager double-confirm it. Add an extra possible value
for the field state on model sale.order, and modify the buttons on the sales
order form. The first confirmation put the sales order in your extra state. The
second confirmation should assign the sales order to the state sale.
Project issues already provide email feedback to their customer. Currently, the email received by the customer of an issue already provides links to view the issue, etc. Add a link inside the email that closes the issue upon click.
When a links in the email is clicked, the url is resolved by an HTTP controller in the Odoo server. The controller is a method that may execute some business code thanks to the Odoo ORM, and it may return a response that renders an HTML template.
Note that creating a new controller is not really necessary: you may use the
existing controllers to achieve what you want (see references below.) Make it
call a method that checks the issue's field stage_id, and modifies it.
When a user encodes some timesheet for a project task, the remaining hours are computed on the task. If the user encodes more hours than the task's planned hours, it may be a sign of a problem on the task. In that case, an email should be sent to the user's manager.
