Indicate the time spent on an answer

User story

As technical,
I want to indicate how much time I spent on an answer,
so it allows an appropriate billing and/or to provide an analysis of the support activity (e.g. the most time-consuming types of requests)

Overview

An new button is added to the answer form in order to enter spent time.
When clicking on the button, it's replaced by an input (number type).
This number is sent with the rest of the form and create a TimeSpent.

The TimeSpent is associated to the current contract if it's ongoing.

The individual spent time appears in the ticket timeline.

The total charged time must appear in the contracts list and in the contract block of the ticket.
When the charged time is above the contract max hours, the contract is considered as finished.

Rule idea

Configure the contract to charge by step (e.g. 30 minutes) to allow the tech to indicate the real spent time and let the app to calculate the charged time e.g. 12 minutes must be charged 30 minutes.

Organization of the answer form

The form to answer must be reorganized so it doesn't look cluttered.
The work has already begun (see #437), but there are still things to do:

• remove the "solution" checkbox (passing the status to "resolved" marks the answer as the solution)
• change the status select box by a menu on the right of the "Answer" button (to answer and change the status)

Entity

A new entity TimeSpent must be created:

• ticket (Ticket)
• time (int)
• real_time (int)
• contract (?Contract)

Permissions

Two new permissions must be added

• orga:create:tickets:time_spent
• orga:see:tickets:time_spent

Changing the ticket contract

When the contract of the ticket is changed, a checkbox must be added to ask the user if the time already spent must be reassigned to this contract.
