Pull request #333 implements a proposal for a business-logic permission system for doccano. The roles we propose are "Annotator" (can annotate documents in a project) and "Annotation Approver" (can approve annotations in a project). Once the pull request is merged, adding a "Guest" or "Viewer" role should be fairly easy. cc @margaretmeehan

Maybe solved in #333

Definitely not solved in #333.

@c-w @margaretmeehan It seems that roles & groups in django are very different. There is no way to assign view-only capabilities to a 'Role' but it is capable to do that to a 'Group'. Can we reopen the issue?

We should be able to extend the role model introduced in #333 to add a "view only" role. A project admin can then invite users to projects and set their role as "view only" so that those users can only see data but not annotate it. This isn't implemented currently but should be a relatively small amount of effort. Would that work for your use-case?

Yes, would work great! Thanks @c-w

See #430 @atakanokan

Looks really good! Hopefully will be merged soon.
