This script validates that certain fields are in the POST request when creating records. If not, an exception is thrown and 500 error returned to the client. If the script exits normally with no exception being thrown, then the records will be written to the database and the post-process script, if any, will be run. lodash.min.js is available by default. The file is located in storage/scripting directory of the DreamFactory installation. You can add your own scripts there and use require() to include them.
// POST /api/v2/db/_table/account triggers script db._table.account.post.pre_process // This script runs BEFORE records are written to the db. // records are in array event.request.payload.resource. var lodash = require("lodash.min.js"); if (event.request.payload.resource) { lodash._.each(event.request.payload.resource, function( record ) { if (!record.hasOwnProperty("annual_revenue")) { throw 'missing field annual_revenue'; } if (record.annual_revenue <= 0) { throw 'annual_revenue must be > 0'; } }); }
