mangusta:trova i dati eseguendo il loop su una matrice di modelli

Controlla questo snippet di codice, ho realizzato un esempio funzionante di ciò di cui hai bisogno.Controlla i commenti nel codice per una migliore comprensione.

Esempio di codice di lavoro simile a quello richiesto. Un'altra domanda di riferimento per l'utilizzo di async con mangusta.

/*
 * Object to store all models
 */
var allRefDatasSchemas = {
  RefAllotement: mongoose.model('RefAllotement', RefDataSchema),
  RefModeleConstructeur: mongoose.model('RefModeleConstructeur', RefDataSchema),
  RefTypeKit: mongoose.model('RefTypeKit', RefDataSchema),
  RefTypeUtilisation: mongoose.model('RefTypeUtilisation', RefDataSchema),
};
/*
 * need an array to run all queries one by one in a definite order using async waterfall mwthod
 */
var arr = [];
for(each in allRefDatasSchemas) {
    arr.push(each);
}

/*
 * Callback function for initiation of waterfall
 */
var queue = [
    function(callback) {
        // pass the ref array and run first query by passing starting index - 0
        callback(null, arr, 0)
    }
];

/*
 * Object to store result of all queries
 */
var finalResult = {};

/*
 * Generic Callback function for every dynamic query
 */
var callbackFunc = function(prevModelData, currentIndex, callback) {
    allRefDatasSchemas[arr[currentIndex]].find(function(err, result) {
        if(err) {
            console.log(err)
        } else {

            // Your Query
            // 
            // I'd like to do something like that :
            // but this.modelName is null, because it isn't the model
            // on which the find is done.

            // arr[currentIndex] will point to 
            // RefAllotement, RefModeleConstructeur etc. as you required
            finalResult[arr[currentIndex]] = result

            // send current result to next interation if required or you can skip
            // and increment the currentIndex to call next query 
            callback(null, result, currentIndex + 1)
        }
    })
}

/*
 * Add callback function for every dynamic query
 */
for(each in allRefDatasSchemas) {
    queue.push(callbackFunc);
}

/*
 * Run all dynamic queries one by one using async.js waterfall method
 */
async.waterfall(queue, function (err, result) {
    // Final object with result of all the queries
    console.log('finish', finalResult)
});

produzione sarà in questo formato

finish { RefAllotement:[
        // Result of RefAllotement query
    ],
    RefModeleConstructeur:[
        // Result of RefModeleConstructeur query
    ],
    RefTypeKit:[
        // Result of RefTypeKit query
    ],
  RefTypeUtilisation:[
        // Result of RefTypeUtilisation query
    ]
}
