DynamoDB single table design in javascript and typescript made easy.

dynamodb-datamodel's Issues

Multiple models?

Hi,
I was looking for a library to use DynamoDb as a single table design and this lib looks promising.
I could not find an example of how to use this with multiple models in a single table, except when having embedded models. Is there a way to use multiple Models in a Single Table? (The definition of the returned model should be left to the user who defines the access patterns)

Update.setIndexes should support undefined and null in values array

Is your feature request related to a problem? Please describe.
Update.setIndexes should support undefined and null in values array . To both skip undefined values and delete null values.

Describe the solution you'd like
See above

Describe alternatives you've considered
Update.delIndexes can be used, but supporting in setIndexes is more convenient with setting multiple indexes.

Additional context
None

Update.del should support having a path param to delete deep items.

Is your feature request related to a problem? Please describe.
Update.del doesn't take any args. To make it easy to delete an entry in a map attribute would be nice if del could support an optional path. Or maybe add a mapDel method so typescript can type check that it can only be used by a map or list attribute.

Describe the solution you'd like
see above

Describe alternatives you've considered
Update.map can be used to do deep deletion, but it isn't obvious or intuitive to use.

Additional context
none

Update.modelMap should support null models that map to delete

Is your feature request related to a problem? Please describe.
Update.modelMap currently requires the inner models to be none null, not allowing the delete operation at the map key level.

Describe the solution you'd like
Update.modelMap should support null which will delete the map key and its data from the item.

Describe alternatives you've considered
Update.delete can be used, but it means that add/update would be separate from delete. Also all properties support null to delete.

Additional context
none
