Hi all,
In my model I have Entities with to-many relationships that I choose
not include as class properties. The problem is when I delete an
eobject of such an entity the delete rules do not apply thus causing
the delete operation to fail. I've overridden the delete method of my
class for EObjects (wich extends ERXGenericRecord) to this :
public void delete() {
for (EORelationship relation : entity().relationships()) {
// to-many relationship that is not in class properties
with
// cascade as delete rule
if (relation.isToMany()
&&
relation._stringFromDeleteRule(relation.deleteRule())
.equals
(EORelationship.DeleteRuleCascadeString)
&& !
entity().classPropertyNames().contains(relation.name())) {
EOQualifier qualifier =
relation.qualifierWithSourceRow(this
.snapshot());
EOFetchSpecification fetchSpecification = new
EOFetchSpecification(
relation.destinationEntity().name(),
qualifier, null);
// fetching objects for the relationship
NSArray<ERXGenericRecord> objects = editingContext()
.objectsWithFetchSpecification
(fetchSpecification);
// now delete them
for (ERXGenericRecord eoGenericRecord : objects) {
eoGenericRecord.delete();
}
}
}
super.delete();
}
This seems to work fine for me, but I was wondering if this is a good
way of handling my problem?
