# What this PR does Fix duplicate `order` values for models `EscalationPolicy` and `ChannelFilter` using the same approach as https://github.com/grafana/oncall/pull/2278. - Make internal API action `move_to_position` a part of [OrderedModelViewSet](https://github.com/grafana/oncall/pull/2568/files#diff-eb62521ccbcb072d1bd2156adeadae3b5895bce6d0d54432a23db3948b0ada54R11-R34), so all ordered model views use the same logic. - Make public API serializers for ordered models inherit from [OrderedModelSerializer](https://github.com/grafana/oncall/pull/2568/files#diff-d749f94af5a49adaf5074325cdfad10ddd5a52dbfd78b49582867ebb9c92fae5R6-R38), so ordered model views are consistent with each other in public API. - Remove `order` from plugin fronted, since it's not being used anywhere. The frontend uses step indices & `move_to_position` action instead. - Make escalation snapshot use step indices instead of orders, since orders are not guaranteed to be sequential (+fix a minor off-by-one bug) ## Which issue(s) this PR fixes https://github.com/grafana/oncall-private/issues/1680 ## Checklist - [x] Unit, integration, and e2e (if applicable) tests updated - [x] Documentation added (or `pr:no public docs` PR label added if not required) - [x] `CHANGELOG.md` updated (or `pr:no changelog` PR label added if not required) |
