Hi, how are u?

I need to run a model method and add in response from Blueprint Actions!

For example, i have the following model:

module.exports = {

attributes: {

//  ╔═╗╦═╗╦╔╦╗╦╔╦╗╦╦  ╦╔═╗╔═╗
//  ╠═╝╠╦╝║║║║║ ║ ║╚╗╔╝║╣ ╚═╗
//  ╩  ╩╚═╩╩ ╩╩ ╩ ╩ ╚╝ ╚═╝╚═╝
tournamentStage: { type: 'number' },
matchTime: {
  type: 'ref',
  columnType: 'datetime',
  required: true
},
//percentRealMeat: { type: 'number', defaultsTo: 20, columnType: 'FLOAT' },

//  ╔═╗╔╦╗╔╗ ╔═╗╔╦╗╔═╗
//  ║╣ ║║║╠╩╗║╣  ║║╚═╗
//  ╚═╝╩ ╩╚═╝╚═╝═╩╝╚═╝

//  ╔═╗╔═╗╔═╗╔═╗╔═╗╦╔═╗╔╦╗╦╔═╗╔╗╔╔═╗
//  ╠═╣╚═╗╚═╗║ ║║  ║╠═╣ ║ ║║ ║║║║╚═╗
//  ╩ ╩╚═╝╚═╝╚═╝╚═╝╩╩ ╩ ╩ ╩╚═╝╝╚╝╚═╝
// Add a reference to Teams
/*players: {
  collection: 'team',
  via: 'matchs'
},*/
localTeam: {
  model: 'team',
},
visitorTeam: {
  model: 'team',
},

localScorePrediction: function () {
  let myPrediction = 0

  /* CODE TO FIND MY PREDICTION */
  return myPrediction;
},
customToJSON: function () {
  console.log('hi, im hereee');
  return _.omit(this, [])
},

},

};

And when i request i don't see the "localScorePrediction" value:

[ { "createdAt": 1528080341248, "updatedAt": 1528080341248, "id": "5b14a7d503d4de23a69b3b82", "tournamentStage": 0, "matchTime": "2018-06-14:00:00.000Z", "localTeam": { "createdAt": 1528030218249, "updatedAt": 1528030218249, "id": "5b13e40a13cc3c0a94d170f7", "name": "Rusia", "img": "https://ssl.gstatic.com/onebox/media/sports/logos/5Y6kOqiOIv2C1sP9C_BWtA_48x48.png" }, "visitorTeam": { "createdAt": 1528030219436, "updatedAt": 1528030219436, "id": "5b13e40b13cc3c0a94d170f8", "name": "Arabia Saudita", "img": "https://ssl.gstatic.com/onebox/media/sports/logos/QoAJxO46fHid3_T-7nRZ0Q_48x48.png" } },

Any ideas?

Thanks!

@tbiancoar If i'm correctly understand your question, you want to append some value to the result when you call Model action right? for example:

when you call Team.find({}) you expect manipulate the data and append your localScorePrediction to the result but you don't want to save it to database right?

for this you can use customToJSON method to append your localScorePrediction calculation. ex:

  /**
   * Omit password from returning User JSON.
   * do you want other user see their password?! 
   * Even tho its encrypted, it's pretty easy to decrypt.
   * This also demo append new things to User Object
   */
  customToJSON: function () {
    // ... do your calculation blablabla..

    const user = _.omit(this, ['password']);
    return _.assign(user, {localScorePrediction: 'your calculation result is here'}); 
    // _.assign is from lodash to append new value to an object.
  },

If you want to save localScorePrediction to database upon creation or update, you can use Model callback for this. see Docs

OR!

you can always do your calculation after getting Team Model inside your controller. it's pretty standard use case.
