Voyage by default provides this: voyageCollectionName "This method can be overridden with a more meaningful collection name" ^ ((self persistentClass name first: 3) allSatisfy: #isUppercase) ifTrue: [ (self persistentClass name allButFirst: 2) asLegalSelector ] ifFalse: [ self persistentClass name asLegalSelector ] So a class name like Association will end up in a mongo collection like "association". But a class name with a prefix like "PDFLetter" will end up in a mongo collection name like "fLetter". Is there a reason for this specific default behavior and not having the class name (by default) as the collection name in mongo? I know I can override the method - but I wonder why it is treated specially also leading to potential conflicts: PDFLetter voyageCollectionName -> #fLetter FLetter voyageCollectionName -> #fLetter Thx T.
