# What this PR does
- Stops writing `SlackMessage.organization` + removes references to this
field. [As we
discussed](https://raintank-corp.slack.com/archives/C083TU81TCH/p1733315887463279?thread_ts=1733311105.095309&cid=C083TU81TCH),
we do not need this field on this model/table,
`SlackMessage._slack_team_identity` is sufficient (`organization` will
be dropped in a separate PR)
- Adds a data migration script which:
- drops orphaned `SlackMessage` records; ie. ones which, even after the
[`engine/apps/slack/migrations/0007_migrate_slackmessage_channel_id.py`](https://github.com/grafana/oncall/blob/dev/engine/apps/slack/migrations/0007_migrate_slackmessage_channel_id.py)
migration, still don't have a `SlackMessage.channel` id filled in (we
discussed + agreed on dropping these records
[here](https://raintank-corp.slack.com/archives/C083TU81TCH/p1733329914516859?thread_ts=1733311105.095309&cid=C083TU81TCH))
- fills in empty `SlackMessage.slack_team_identity` values (from
`slack_message.channel.slack_team_identity`)
### Other notes
On the `organization` topic.
We store records in `SlackMessage` for two purposes (AFAICT), and in
both cases, we have references back to the `organization`:
- alert groups - `slack_message.alert_group.channel.organization`
- shift swap requests - `shift_swap_request.schedule.organization`

# What this PR does
- As a follow-up to https://github.com/grafana/oncall/pull/5292, and now
that `SlackMessage.channel` has been migrated via
[`engine/apps/slack/migrations/0007_migrate_slackmessage_channel_id.py`](https://github.com/grafana/oncall/pull/5292/files#diff-8aebe133401715a4262baad9b2c5c9fc59367c18d6bd6ac2b3c462fcdabafd66),
this PR removes reads/writes from `SlackMessage._channel_id` to
`SlackMessage.channel`. In a separate PR I will focus on dropping that
column from the model/db.
- Drops `SlackMessage.active_update_task_id`. There're zero references
to this column in the codebase.
- Removes two Django `manage.py` commands that're no longer needed:
- `engine/engine/management/commands/alertmanager_v2_migrate.py` (and
it's associated tests)
-
`engine/engine/management/commands/batch_migrate_slack_message_channel.py`

The two asks in the [original GH
issue](https://github.com/grafana/oncall-private/issues/2947) were:
> 1. Make the error message clearer. We can identify if it's delivering
or updating and being rate-limited. This is possible because Slack sets
limits per API method. Also, this limit is a per-slack channel while we
are posting messages & applying ratelimit per on-call integration, which
confuses customers.
> 2. Debounce update alert group message in Slack
Both of these have been addressed in this PR

**NOTE**
This PR introduces steps 1 and 2 of the 3 part migration proposed
[here](https://raintank-corp.slack.com/archives/C06K1MQ07GS/p1732555465144099).
Step 3, swapping reads to be from the new-column and dropping
dual-writes, will be done in a future PR/release.
---
I’m tackling this work now because _ultimately_ I want to move
`AlertReceiveChannel.rate_limited_in_slack_at` to
`SlackChannel.rate_limited_at` , but first I sorta need to refactor
`SlackMessage.channel_id` from a `CHAR` field to a foreign key
relationship (because in the spots where we touch Slack rate limiting,
like
[here](https://github.com/grafana/oncall/blob/dev/engine/apps/slack/alert_group_slack_service.py#L42-L50)
for example, we only have `slack_message.channel_id`, which means I need
to do extra queries to fetch the appropriate `SlackChannel` to then be
able to get/set `SlackChannel.rate_limited_at`
Other minor stuffs:
- it also prepares us to drop `SlackMessage._slack_team_identity`. We
already have a `@property` of `SlackMessage.slack_team_identity` (which
[previously had some hacky
logic](https://github.com/grafana/oncall/blob/dev/engine/apps/slack/models/slack_message.py#L74-L84)).
I've refactored `SlackMessage.slack_team_identity` to simply point to
`self.organization.slack_team_identity` + updated our code to _stop_
setting `SlackMessage._slack_team_identity` (will drop this column in
future release)

# What this PR does
This PR adds
[django-migration-linter](https://github.com/3YOURMIND/django-migration-linter)
to keep database migrations
backwards compatible
- we can automatically run migrations and they are zero-downtime, e.g.
old code can work with the migrated database
- we can run and rollback migrations without worrying about data safety
- OnCall is deployed to the multiple environments core team is not able
to control
See [django-migration-linter
checklist](https://github.com/3YOURMIND/django-migration-linter/blob/main/docs/incompatibilities.md)
for the common mistakes and best practices
