[Pharo-users] Voyage: VOToOneDescription or VOMongoToOneDescription

[Hilaire]

Hi,

VOToOneDescription or VOMongoToOneDescription, that is the question?

I am confuse because:

This one works:

mongoStartDate
<mongoDescription>
^ VOToOneDescription new
   attributeName: 'startDate';
   accessor: (MAPluggableAccessor
      read: [:loan | loan startDate]
      write: [:loan :dateAndTime | loan startDate: dateAndTime asDate]);
   yourself



This one breaks:

mongoStartDate
<mongoDescription>
^ VOMongoToOneDescription new
   attributeName: 'startDate';
   accessor: (MAPluggableAccessor
      read: [:loan | loan startDate]
      write: [:loan :dateAndTime | loan startDate: dateAndTime asDate]);
   yourself


However, the tutorial on Entreprise Pharo book only mention the later one.

So what the differences?

Thanks

Hilaire
