Subject [DISCUSS] Major business logic refactoring: Move from Account to UserAccount
Date Fri, 14 Nov 2014 08:53:13 GMT

All CloudStack DB entities (VM, storage, network etc.) have an owner field which is mostly
the account. An account can have multiple users so just by looking at the resource (say VM)
it’s not possible to make out which user in the account (owner or account_id field in the
db row of the entity) created it. CloudStack users may want to know this information for at
least entities such as VMs and Volumes.

Historically, why is the account owner of an entity and not a user? If user were the owner,
we could easily get the account Id using the user Id.

One solution to fix this problem is to refactor and replace Account (interface) usage with
UserAccount (interface) usage, fix the DAO and resource layer, and add columns in the schema.
This gets us all the information we need to determine domainId, AccountId and Id (the user
ID). Should we do it for all entities or just keep status quo (use account as owners), or
just fix it on-demand basis for specific entities such as for user VMs [1].
