# Rollout

## Context
Nowadays the Pilot Program -- and so the Attachment Requirement -- it's under a **feature flag** controlled by [rollout](https://github.com/fetlife/rollout) gem.

## How it is

**TimeSheet** has a `required_attachment` field being enforced with `false` by the `set_required_attachment` callback before saving.

**Payroll** has a `required_attachment` field filled during `run_before_save_hooks` callback before save. It will call the `required_attachment?` method whos look if there's a `Timekeeping::Rule` with `required_attachment` flag as `true`.

## How will it be

**TimeSheet** must have `required_attachment` field filled during `set_required_attachment` callback before save. It will call the `required_attachment?` method -- **which is under rollout flag**.

**Payroll** must have `required_attachment` field filled during `run_before_save_hooks` callback before save. It will delegate the `required_attachment?` call to `TimeSheet`.

## Rollout phase
