Breeze: How do I force a refresh of an entity in cache

How can I force the cache to update?

I have an entity that is actually a view in the database. I want force the cached entity to edit. Generally, when saving an entity, the cache is updated as well. But in this case, I cannot save the entity as it is a view. I therefore want to force the cache to refresh and read the updated values from the database.

How can I do this please?

Solution

  • Requery for the entity with a MergeStrategy of OverwriteChanges. Something like.

    var entityKey = myEntity.entityAspect.getKey();
var query = EntityQuery.fromEntityKey(entityKey)
    .using(MergeStrategy.OverwriteChanges);
myEntityManager.executeQuery(query).then(...);

    After the promise resolves the latest version of the entity will be in cache.
