The HTML interface does this by default for every detected foreign key\n                column - you can turn that off using  ?_labels=off . \n             You can request foreign keys be expanded in JSON using the  _labels=on  or\n                 _label=COLUMN  special query string parameters. Here's what an expanded row\n                looks like: \n             [\n    {\n        \"rowid\": 1,\n        \"TreeID\": 141565,\n        \"qLegalStatus\": {\n            \"value\": 1,\n            \"label\": \"Permitted Site\"\n        },\n        \"qSpecies\": {\n            \"value\": 1,\n            \"label\": \"Myoporum laetum :: Myoporum\"\n        },\n        \"qAddress\": \"501X Baker St\",\n        \"SiteOrder\": 1\n    }\n] \n             The column in the foreign key table that is used for the label can be specified\n                in  metadata.json  - see  Specifying the label column for a table .", "breadcrumbs": "[\"JSON API\"]", "references": "[]"}
