How can I delete entities belonging to a service path that I don't remember?

Question

When you want to delete an entity from Fiware Orion, you need to provide its ServicePath, Then how do you delete an item if you don't know its service path ?

Answer 1

Currently, Orion API doesn't allow such operation directly, but as workaround you can know the service path to which an entity belongs with a query on the MongoDB database.

Let's assume the entity ID is Room1, entity the type is Room and you are using the default database name (i.e. orion), you can run the following command (in the same host where the MongoDB database runs).

echo 'db.entities.find({"_id.id": "Room1", "_id.type": "Room"}, {_id: 1})' | mongo orion --quiet

You will get a result like this one:

{ "_id" : { "id" : "Room1", "type" : "Room", "servicePath" : "/path" } }

The servicePath field specifies the entity service path (/path in the above example).
