Hello hello ! Im a bit confused regarding CacheKeys and removals.
given this declarative key extend type WorkOrderType @typePolicy(keyFields: "id")
and this records key like:

workOrder({"id":"J-2B387F98"})
workOrder({"id":"J-2B387F98"}).project

The proper way to delete them would be

apolloClient.apolloStore.remove(CacheKey("WorkOrder:${workorderId}"))

but it has no effect

[mbonnin]

There are object keys and field keys. workOrder({"id":"J-2B387F98"}) sounds like a field key from the root for a query like

query GetWorkOrder($id: String) {
  workOrder(id: $id) { ... }
}

[mbonnin]

This field key should point to the object key like CacheKey("WorkOrder:${workorderId}")

[mbonnin]

But removing the CacheKey("WorkOrder:${workorderId}") record doesn’t remove the root field references (if this is what you were expecting?)

[Marco Pierucci]

Hmm interesting, what woulb be the correct way to delete that root reference? ( and cascade?

[mbonnin]

No real good solution so far

[Marco Pierucci]

does that mean that my declarative keys are wornlgy set?

[mbonnin]

If you wanted to remove a field in the root record, you’d have to overwrite the root record currently

[Marco Pierucci]

write the cache then? setting it blank on purpose?

[mbonnin]

yep

[mbonnin]

That would trigger the watchers if this is what you’re after

[mbonnin]

The easiest way is to call writeOperation with the new data

[Marco Pierucci]

Im not watching the cace but Id liek to evict the resutl for that query so if they re enter they neednetwork agan

[Marco Pierucci]

ok

[Marco Pierucci]

thanks!

[mbonnin]

Sure thing!

[mbonnin]

Note that removing CacheKey("WorkOrder:${workorderId}") should still trigger a cache miss

[mbonnin]

The cache will read workOrder({"id":"J-2B387F98"}) which points to CacheKey("WorkOrder:${workorderId}") and trigger a cache miss at that point

[mbonnin]

If not, it means there’s something else. If you’re not already using it, the IJ plugin cache viewer can help there

[Marco Pierucci]

excelllent

[Marco Pierucci]

thnaks again

[mbonnin]

No problem! Let us know how that goes!

[Marco Pierucci]

sure thing
