trying to use observe

[jmls]

I was trying to implement the new operation hooks, as documented here : http://docs.strongloop.com/display/public/LB/Operation+hooks

however, I'm not sure where to put the code

I have this in my ng-model.js 

module.exports = function(NgModel) {

NgModel.observe('before save', function(ctx, next) {

but get the error

TypeError: Object function ModelConstructor(data, options) {

server-0 (err):       if (!(this instanceof ModelConstructor)) {

server-0 (err):         return new ModelConstructor(data, options);

server-0 (err):       }

server-0 (err):       if (ModelClass.settings.unresolved) {

server-0 (err):         throw new Error('Model ' + ModelClass.modelName + ' is not defined.');

server-0 (err):       }

server-0 (err):       ModelBaseClass.apply(this, arguments);

server-0 (err):     } has no method 'observe'

server-0 (err):     at module.exports (/opt/nodegloo/common/models/ng-model.js:8:11)

server-0 (err):     at /opt/nodegloo/node_modules/loopback-boot/lib/executor.js:193:11

server-0 (err):     at Array.forEach (native)

server-0 (err):     at setupModels (/opt/nodegloo/node_modules/loopback-boot/lib/executor.js:160:3)

server-0 (err):     at execute (/opt/nodegloo/node_modules/loopback-boot/lib/executor.js:33:3)

server-0 (err):     at bootLoopBackApp (/opt/nodegloo/node_modules/loopback-boot/index.js:129:3)

server-0 (err):     at Object.<anonymous> (/opt/nodegloo/server/server.js:79:1)

server-0 (err):     at Module._compile (module.js:456:26)

server-0 (err):     at Object.Module._extensions..js (module.js:474:10)

it seems that the problem is "has no method 'observe'" 

so, where should I put this code ?

thanks

Hi,

I've the same issue, Could you please explain to me how do you solve it?

I was using version 2.4.1 - you need to update to 2.12 or above (i think)
