V8 Script has no effect, but var_dump shows change

Server-Side Scripting
1

For some reason, v8 scripting is having no effect over the API calls.
I have installed DreamFactory manually, so I was wondering if it’s perhaps to do with the V8 php mod I’m using (0.4.1)

I’ve previously installed DF using Bitnami on other servers and have written V8 scripts in the past, so I’m relatively sure I’m doing everything correctly.

Just to give a little more info on this. lodash doesn’t seem to be working for some reason, so I’m now using the sample code with a standard for loop on post process of table{name} GET:

//****************** Post-processing script on a table ******************

// A script that is triggered by a GET on /api/v2/db/_table/. Runs after the db call is made.
// The script adds a new field to each record in the response.

var lodash = require(“lodash.min.js”);

if (event.response.content.resource) {

for (var i = 0; i < event.response.content.resource.length; i++ ) {

   event.response.content.resource[i].extraField = 'Feed the dog.';
}

// outputs to file in storage/log of dreamfactory install directory
var_dump(event.response.content);
}

The output in dreamfactory.log is as follows:

The problem was due to a change in the spec that means you now need to set the content_changed flag to true for scripts to have any effect:

event.response.content_changed = true;
