# What this PR does
Remove
[`apps.get_model`](https://docs.djangoproject.com/en/3.2/ref/applications/#django.apps.apps.get_model)
invocations and use inline `import` statements in places where models
are imported within functions/methods to avoid circular imports.
I believe `import` statements are more appropriate for most use cases as
they allow for better static code analysis & formatting, and solve the
issue of circular imports without being unnecessarily dynamic as
`apps.get_model`. With `import` statements, it's possible to:
- Jump to model definitions in most IDEs
- Automatically sort inline imports with `isort`
- Find import errors faster/easier (most IDEs highlight broken imports)
- Have more consistency across regular & inline imports when importing
models
This PR also adds a flake8 rule to ban imports of `django.apps.apps`, so
it's harder to use `apps.get_model` by mistake (it's possible to ignore
this rule by using `# noqa: I251`). The rule is not enforced on
directories with migration files, because `apps.get_model` is often used
to get a historical state of a model, which is useful when writing
migrations ([see this SO answer for more
details](https://stackoverflow.com/a/37769213)). So `apps.get_model` is
considered OK in migrations (even necessary in some cases).

# What this PR does
Fixes an issue when multiple user notification policies have duplicated
order values, leading to the following unexpected behaviours:
1. Not possible to rearrange notification policies that have duplicated
orders.
2. The notification system only executes the first policy from each
order group. For example, if there are policies with orders `[0, 0, 0,
0]`, only the first policy will be executed, and all others will be
skipped. So the user will see four policies in the UI, while only one of
them will be actually executed.
This PR fixes the issue by adding a unique index on `(user_id,
important, order)` for `UserNotificationPolicy` model. However, it's not
possible to add that unique index using the ordering library that we use
due to it's implementation details.
I added a new abstract Django model `OrderedModel` that's able to work
with such unique indices + under concurrent load.
Important info on this new `OrderedModel` abstract model:
- Orders are unique on the DB level
- Orders are allowed to be non-consecutive, for example order sequence
`[100, 150, 400]` is valid
- When deleting an instance, orders of other instances don't change.
This is a notable difference from the library we use. I think it's
better to only delete the instance without changing any other orders,
because it reduces the number of dependencies between instances (e.g.
Terraform drift will be much smaller this way if a policy is deleted via
the web UI).

* Modify plugin.json to support RBAC role registration
* defines 26 new custom roles in plugin.json. The main roles are:
- Admin: read/write access to everything in OnCall
- Reader: read access to everything in OnCall
- OnCaller : read access to everything in OnCall + edit access to Alert Groups and Schedules
- <object-type> Editor: read/write access to everything related to <object-type>
- <object-type> Reader: read access for <object-type>
- User Settings Admin: read/write access to all user's settings, not just own settings. This is in comparison to User Settings Editor which can only read/write own settings
* update changelog and documentation (#686)
* implement RBAC for OnCall backend
This commit refactors backend authorization. It trys to use RBAC authorization if the org's grafana instance supports it, otherwise it falls back to basic role authorization.
* update RBAC backend tests
* add tests for RBAC changes
- run backend tests as matrix where RBAC is enabled/disabled. When RBAC is enabled, the permissions granted are read from the role grants in the frontend's plugin.json file (instead of relying what we specify in RBACPermission.Permissions)
- remove --reuse-db --nomigrations flags from engine/tox.ini
- minor autoformatting changes to docker-compose-developer.yml
* remove --ds=settings.ci-test from pytest CI command
DJANGO_SETTINGS_MODULE is already specified as an env var so this is just unecessary duplication
* update gitignore
* update github action job name for "test"
* RBAC frontend changes
* refactors the use of basic roles (ex. Viewer, Editor, Admin) use RBAC permissions (when supported), or falling back to basic roles when RBAC is not supported.
- updates the UserAction enum in grafana-plugin/src/state/userAction.ts. Previously this was hardcoded to a list of strings that were being returned by the OnCall API. Now the values here correspond to the permissions in plugin.json (plus a fallback role)
* changes per Gabriel's comments:
- get rid of group attribute in rbac roles
- remove displayName role attribute
- remove hidden role attribute
- add back role to includes section
* don't try to update user timezone if they don't have permission
