# What this PR does
Adds mobile app settings support to OnCall backend.
- Adds a new Django model `MobileAppUserSettings` to store push
notification settings
- Adds a new endpoint `/mobile_app/v1/user_settings` to fetch/update
settings from the mobile app
Some additional info on implementation: at first I wanted to extend the
messaging backend system to allow storing / retrieving per-user data and
implement mobile app settings based on those changes. After some thought
I decided not to extend the messaging backend system and have this as
functionality specific to the `mobile_app` Django app. Currently the
messaging backend system is used by the backend and plugin UI, but
mobile app settings are specific only to the mobile app and not
configurable in the plugin UI.
**tldr: wanted to extend messaging backend system, but decided not to do
that**
# Usage
## Get settings via API
`GET /mobile_app/v1/user_settings`
Example response:
```json
{
"default_notification_sound_name": "default_sound", # sound name without file extension
"default_notification_volume_type": "constant",
"default_notification_volume": 0.8,
"default_notification_volume_override": false,
"important_notification_sound_name": "default_sound_important", # sound name without file extension
"important_notification_volume_type": "constant",
"important_notification_volume": 0.8,
"important_notification_override_dnd": true
}
```
## Update settings via API
`PUT /mobile_app/v1/user_settings` - see example response above for
payload shape.
Note that sound names must be passed without file extension. When
sending push notifications, the backend will add `.mp3` to sound names
and pass it to push notification data for Android. For iOS, sound names
will be suffixed with `.aiff` to be used by APNS.
## Get settings from notification data for Android
All the settings from example response will be available in push
notification data (along with `orgId`, `alertGroupId`, `title`, etc.).
Fields `default_notification_volume`,
`default_notification_volume_override` and
`important_notification_volume` , `important_notification_override_dnd`
will be converted to strings due to FCM limitations.
Fields `default_notification_sound_name` and
`important_notification_sound_name` will be suffixed with `.mp3` in push
notification data.
## iOS limitations
While Android push notifications are handled purely on the mobile app
side, iOS notifications are sent via APNS which imposes some
limitations.
- Notification volume cannot be overridden for non-critical
notifications (so fields `default_notification_volume_override` and
`default_notification_volume` will be disregarded for iOS notifications)
- It's not possible to control volume type (i.e. "constant" vs
"intensifying") via APNS. A possible workaround is to have different
sound files for "constant" and "intensifying" and pass that as
`default_notification_sound_name` / `important_notification_sound_name`.
# Which issue(s) this PR fixes
Related to https://github.com/grafana/oncall-private/issues/1602
# Checklist
- [x] Tests updated
- [x] No changelog updates since the changes are not user-facing
- removes APNS support
- changes the `django-push-notification` library from the `iskhakov`
fork to the [`grafana`
fork](https://github.com/grafana/django-push-notifications). This new
fork basically just patches an issue which affected the database
migrations of this django app (previously the library would not respect
the `USER_MODEL` setting when creating its tables and would instead
reference the `auth_user` table.. which we don't want)
- add `--no-cache` flag to the `make build` command
**NOTE**
A migration should be applied as follows:
```bash
# remove the four push_notifications tables, which have improper foreign key references
python manage.py migrate push_notifications zero
# recreate the tables with the proper foreign key references
python manage.py migrate
```
