Permissions: read-write in a workflow context, read-only otherwise
Article ID: KB0075866
Updated On:
| Products | Versions |
|---|---|
| TIBCO EBX | All supported versions. |
Description
In this article we will show you how to define dynamic permissions depending on whether we are in a workflow context or not.
In order to achieve this, we will have to implement a programmatic rule AccessRule that we will apply on the concerned node(s) in a data model extension SchemaExtensions.
Please see reference section.
Resolution
Example
I want my "Products" table to be updatable in a workflow context only.
SchemaExtensions implementation
mySchemaExtensions.javapublic void defineExtensions(SchemaExtensionsContext context) { final AccessRule accessRuleOnProducts = new AccessRuleOnProducts(); context.setAccessRuleOnNode(Path.parse("/root/products"), accessRuleOnProducts); } |
AccessRule implementation
AccessRuleOnProducts.javapublic AccessPermission getPermission(Adaptation record, Session session, SchemaNode node) { if (session.isInWorkflowInteraction(true)) return AccessPermission.getReadWrite(); else return AccessPermission.getReadOnly();} |
