Extend InventInventoryDimensionEntityFieldsMapping map to add new field mapping

(2) ShareShare

Posted on by CU17062046-0 6
Hello, I am trying to extend InventInventoryTransferJournalEntryEntity entity and that entity uses InventInventoryDimensionEntityFieldsMapping map to map the inventory dimensions. I have a requirement now to add new fields to the data entity. These new fields are the generic inventory dimensions like InventDimension1, InventDimension2, etc that my client uses. I could not find the standard interface to this map to extend. What would be the better approach to extend this map?

    maps are not extensible. so you cannot directly add fields or methods to it.

    It seems that you don't really want to extend the map; you want to extend the entity a map fields of the map (such as InventDimension1) to custom fields added to the entity. Nevertheless it isn't supported either.
     
    Instead, you'll need to extend code and get InventDimId for the dimension values by yourself. If you look at what the map does (in InventInventoryDimensionEntityFieldsMapping.resolveInventDim()), you'll see that it's nothing complicated. It simply assigns values of InventDim fields and calls InventDim::findOrCreate(). You can do that in your code too. The entity calls the logic in mapEntityToDataSource().
