extends audit service to support adapters in EL expressions
-----------------------------------------------------------
Key: NXP-4657
URL: http://jira.nuxeo.org/browse/NXP-4657
Project: Nuxeo Enterprise Platform
Issue Type: Improvement
Reporter: Eugen Ionica
*issue : with current audit service can NOT log values resulted from customized
method calls
Audit Service use EL expression to add extra information to be logged.
For now there are 3 objects available in the context to be used in EL
expressions:
message - Document message describing the event
source - Document from which the event is from
principal - Identity of the event owner
<extension point="extendedInfo"
target="org.nuxeo.ecm.platform.audit.service.NXAuditEventsService">
<extendedInfo expression="${source.myschema.myproperty}" key="extraInfo" />
</extension>
But sometimes we need to implement some logic to produce the value that we want
to record
in our case
[...]
if (doc.isProxy()) {
CoreSession session = CoreInstance.getInstance().getSession(sessionId);
DocumentModel tmp = session.getSourceDocument(doc.getRef());
originalDocUUID = session.getSourceDocument(tmp.getRef()).getId();
}
else {
originalDocUUID = doc.getId();
}
[...]
* posbile solution
added a new extension point to
org.nuxeo.ecm.platform.audit.service.NXAuditEventsService called "docAdapter"
using this point will register an adapter for DocuementModel
<extension point="doc"
target="org.nuxeo.ecm.platform.audit.service.NXAuditEventsService">
<adapter class="org.nuxeo.myadapter" name="myadapter" />
</extension>
class - is the qualified name of the class that will wrap the document model
specified by "source"
name - is the name that will be used in EL
then win "extendedInfo" will add
<extension point="extendedInfo"
target="org.nuxeo.ecm.platform.audit.service.NXAuditEventsService">
<extendedInfo expression="${myadapter.originalDocUUID}"
key="original_doc_uuid" />
</extension>
