Trying to sort by non-mentioned in the model files field (using "schema: false") and getting "Cannot read property 'columnName' of undefined". Got no problems when using fields described in model files.

Also, it used to work fine until I migrated to v1 (from v.012). Now fixed this for myself, changing forge-stage-three-query.js to processed not known fields.

https://github.com/balderdashy/sails/issues/4105 and https://trello.com/c/b57sDgVr/124-adapter-spec-change-to-allow-for-more-flexible-base-values seem related.

Start in forge-stage-three-query.js, where the report says the query processing fails when sorting by a field absent from the model with schema: false. Reproduce the error using a non-model sort field and compare it with sorting by a declared field. Done means the former no longer raises the undefined columnName error and the behavior remains compatible with the related adapter changes.
