Create model in model

问题

I'm new to strongloop and look at documentation and samples but never see my problem as desired. I'v two models, sentence.js and log.js and making post request a sentence from mobile app to rest-api, for example

Model sentence.js (dont want save to db this model, only for parsing and creating log model)
{
  name: 'sentence',
  type: 'string'
}

Model  log.js
{ name: 'lat', type: 'string' },
{ name: 'lng', type: 'string' }

[HTTP POST]  myserver/api/sentence?d=$GPRMC,123519,A,4807.038,N,01131.000,E,022.4,084.4,230394,003.1,W*6A

A model has triggered methods, e.g, afterInitialize, beforeValidate , beforeSave. Now, which triggered method or any other scope correct and best for parsing sentence model and creating log model ?

Thanks !

回答1:

In your case the best place is

Sentence.beforeRemote('create', function(ctx, sentence, next){
  console.log(ctx.req.body); 
  next()
})

Also Model hook Sentence.afterInitialize and Model Event Sentence.on('set') are available, but will be called in some extra cases.

(Note that in my case I would use remote hooks and only ONE Log model.)
