Simplifies the errors from mongoose's scheme validation with internacionalization (i18nex) support
## Validation Error
## Before
```json
message: "domain validation failed",
name: "ValidationError",
errors: {
myField: {
properties: {
type: "required",
message: "ERROR MESSAGE",
path: "myField",
value: ""
},
message: "ERROR MESSAGE",
name: "ValidatorError",
kind: "required",
path: "myField",
value: ""
}
```
## After
```json
errors: {
myField: "domain.domainRequired"
}
```
## Mongo Error
## Before
```json
{
driver: true,
name: "MongoError",
index: 0,
code: 11000,
errmsg: "E11000 duplicate key error collection: reportsService.service_5d272c4bf7b1cd009d593403 index: origin_id_1 dup key: { : \"TestOrigin\" }"
}
```
## After
```json
errors: {
MongoError: "E11000 duplicate key error collection: reportsService.service_5d272c4bf7b1cd009d593403 index: origin_id_1 dup key: { : \"TestOrigin\" }"
}
```
## Exemple 1 ( Without internacionalization )
```javascript
// LOAD THE RESOURCES
mongoose = require('mongoose');
config = require('../config/general');
mongoose.connect(config.database);
// LOAD MODULE
mongooseErrorHandler = require('mongoose-error-handler');
// LOAD MODEL
var myModel = require('../models/myModel');
var newModel = new myModel({
myField: 'foo',
});
var error = newModel.validateSync();
console.log(mongooseErrorHandler.set(error));
```
## Exemple 2 - A Route in Node.js Express( With i18next internacionalization )
```javascript
// LOAD THE RESOURCES
router = require('express').Router();
mongoose = require('mongoose');
config = require('../config/general');
mongoose.connect(config.database);
// LOAD MODULE
mongooseErrorHandler = require('mongoose-error-handler');
// LOAD MODEL
var myModel = require('../models/myModel');
router.post('/myroute', function(req, res, next) {
var newModel = new myModel({
myField: 'foo',
});
// save
newModel.save(function(err) {
if(err)
// An Example of error handling
res.status(400).json({success: false, msg: mongooseErrorHandler.set(error, req.t)});
else
res.status(200).json({success: true, msg: req.t('myInternacionalizedString')});
});
});
module.exports = router;
```
## Exemple 3 - A Route in Node.js Express( With i18next internacionalization and String Replacement )
```javascript
// LOAD THE RESOURCES
router = require('express').Router();
mongoose = require('mongoose');
config = require('../config/general');
mongoose.connect(config.database);
// LOAD MODULE
mongooseErrorHandler = require('mongoose-error-handler');
// LOAD MODEL
var myModel = require('../models/myModel');
router.post('/myroute', function(req, res, next) {
var newModel = new myModel({
myField: 'foo',
});
// save
newModel.save(function(err) {
if(err)
// An Example of error handling
res.status(400).json({
success: false,
msg: mongooseErrorHandler.set(error, req.t, {variable: 'stringForReplacement'})
});
else
res.status(200).json({success: true, msg: req.t('myInternacionalizedString')});
});
});
module.exports = router;
```
## Tests
```
$ npm test
```
