Deployment names not updating through the UI

[mthatt]

Bug summary

Updating a deployment name through the UI doesn't seem to work. I see a deployment.updated event in the audit log and event feed, but the deployment name doesn't change.

On a related note, I thought this was possible to update via the API but PATCH'ing a deployment with name returns a 422 Unprocessable Entity.

to surface discussion, patching the deployment name is not currently possible, as it would need to be a field on DeploymentUpdate

@mthatt the recommendation would be to recreate the deployment with a new name, we should probably remove the apparent option to update the name in the UI to reduce confusion
