How to create multiple order detail lines with one saveChanges

Is it possible to create multiple order detail lines using manager.createEntity(entityName) and save the whole bundle using a single manager.saveChanges().

Can anyone point me to an example?

Any help appreciated.

Regards, Paul

Solution

  • You'll see numerous descriptions of entity graph save in the documentation. It's simple really:

    • create the entities

    • make sure they are related which is as simple as assigning the parent to the pertinent navigation property of each child.

    • call entityManager.saveChanges() to save the entire lot of pending changes as a single transaction.

    There is a particularly apt test, "can save new Order and its OrderDetails in one transaction", in the saveNorthwindTests.js file in the DocCode sample
