Has anyone been able to successfully implement ERAttachment with StorageType = “db”? The following is my question/difficulty:
I am still wrestling with ERAttachment ‘magic’..!! I can finally ‘easily’
upload attachment files and populate <ERAttachment/ERAttachmentData> database
entities <i.e: with ERDatabaseAttachment.STORAGE_TYPE =“db” >, but I can’t
figure/find out the magic that’s required to set the Owning EO’s
<MasterObject’s> Attribute Value for the to-one ‘destination’ RelationshipKey.
That is: when and how is the JOIN attribute VALUE SET by the attachment
<ERAttachment>, so that when the owning EO (masterObject) is retrieved the
appropriate attachment is located and rendered?
RelationshipKey myAttachment ====>> MasterObject {attachmentID}
————>ERAttachment {id}
such that: MasterObject.myAttachment() = stored_attachment
In short, the correct corresponding attachment is retrieved ONLY if:
MasterObject. attachmentID() = ERAttachment.id()
But can’t see when/where MasterObject. attachmentID is set!
Can’t find it in documentation or Javadoc (api: Project Wonder 7.0.0-SNAPSHOT)
Any help will be appreciated.. Thank you!
PS: The attachments are created and saved in the DB but the attachmentID is NOT
set in the owning/masterObject !!!
