How to return IDs and Labels?

[jasperblues]

Hi @joeykilpatrick Thanks for reporting.

Drivine has a default result mapper. Given the goal of creating a library that supports building graph-powered REST APIs and similar, the rationale is to make 80% of such cases simpler and 20% possible.

It is possible to do what you would like. Here are some options:

Return the Id and Label Properties from Query:

MATCH (actor:Person {name: $1})
WITH actor, [(actor)-[:ACTED_IN]-(movie:Movie) | movie {.title, .tagline, .released}] as movies
RETURN {
         id: id(actor),  <--- HERE 
         labels: labels(actor), <-- AND HERE
         actor:  actor,
         movies: movies
       }

Plug in Your Own Result Mapper

Rather than use the default result mapper you can plug in your own. Would you like to contribute an alternative mapper that:

• Does what you want.
• Users can specify as a config options when bootstrapping (becomes the default) or when executing a query (overrides the default).

Such a mapper could be Neo4j-specific if you wished, would not have to be general case for all supported graph DBs.

Use Neo4j Driver directly.

Another option is to use Neo4j driver directly. This would be a good idea if you prefer that format, and also don't wish to use other Drivine features like the transaction system, cursors, etc.

I will leave this issue open in case you would like to pursue option #2 - Plug in your own mapper.

Closed for now @joeykilpatrick. Let me know if/when you would like to plug in a custom mapper, and we can help out.

(btw #53 Gets us most of the way there).
