Description

This PR updates a some functionality around the Data Steward attribute. It restricts the Data Steward to workspace users with the Collaborator, Admin or Workspace Lead roles, and automatically assigns Data Steward to the workspace lead whenever a new workspace is created. It also adds some under-the-hood improvements on the workspace users page.

Task 10137: Update the workspace users page under the hood and add unit tests

Changes

• Data Steward is restricted to Collaborators, Admins, and Workspace Leads. If changing the user role, the data steward attribute will be un-set both in the UI and when saving to the database if the user role changes to a disallowed one. The data steward checkbox in the UI will also be disabled in this case.
• When a new workspace is created, the workspace lead will automatically be assigned as data steward by default.
• Searching/filtering the workspace user list takes effect immediately, and is implemented more efficiently under the hood
• Greatly improved unit test coverage of the workspace user page

Testing

• Manual testing of workspace user page, role update and data steward update
• Updated unit tests of the workspace users page and workspace user management service
