这个模型怎么了

Question

I need to develop a module for getting data from mongodb, I already have other models working in my application, but this one does not, this is my schemas:

var mongoose = require('mongoose');
var ProvinciaSchema = new mongoose.Schema({
"nome":String,
"tc_provincia_id":Number,
"id" : Number,
"codice_regione" : Number,
"codice" : Number,
"sigla" : Number
},{collection:'province'})
module.exports = ProvinciaSchema;

this is my model:

var mongoose = require('mongoose');
var ProvinciaSchema = require('../schemas/provincia');
var Provincia = mongoose.model('provincia', ProvinciaSchema);
module.exports = Provincia;

This is how I use the model:

var Provincia = require('../../models/provincia');
Provincia.find({},next( err, province){
if (err){console.log('errorre whoosh '+err);
     return next(err,province)
     }
     if (!province){console.log('trovato nulla')}
     console.log('callback tc_istat_id')
     return next(err,province)
 })

where

next =function(err,prov){
    t.equivalent(out,expect)
    t.end()

when I launch the test if the condition argument is correct, the execution stuck at Provincia.find and the callback function it is not executed, if I put a wrong condition the section of the code of if(err) is executed, I think there is a problem with my schemas abnd models, but I do not understand what.

Answer 1

 function myFunction(callback) {
       Provincia.find({},next( err, province){
            if (err) {
                console.log('errorre whoosh '+err);
                return next(err,province)
             }
            if (!province){
                console.log('trovato nulla');
                return false;
            }
            console.log('callback tc_istat_id')


            callback(err,province)
       })
 }

 myFunction(function(err,prov){
     t.equivalent(out,expect)
     t.end()
 });

I had no way of testing this but it is how I would set up my callback function. Let me know what you log, and what errors your get if this does not work
