Get by id

g.sys.db.getById calls the get by id schema API of any table from your code, with the same headers and query parameters as over HTTP. It returns the data, or the whole envelope when true is passed as the second argument.

});

Multi-tenant

  • instance: "crm::acme" works on the database of the tenant acme of the multi-tenant instance crm.
  • With instance: "crm", the call works on the database of the tenant of the request: a custom API called with the x-am-tenant-username header passes it on to the APIs it calls. A request without a tenant works on the structure database.
