Mongoose Schema method: Error - model method is not a function

I have two Mongoose model schemas as follows. The LabReport model contains an array of the referenced SoilLab model. There is a static method in the SoilLab model that I was using to select which fields to display when LabReport is retrieved.
//LabReport.js
var mongoose = require("mongoose");
var SoilLab = mongoose.model("SoilLab");
var LabReportSchema = new mongoose.Schema(
{
labFarm: { type: mongoose.Schema.Types.ObjectId, ref: "Farm" },
testName: { type: String },
soilLabs: [{ type: mongoose.Schema.Types.ObjectId, ref: "SoilLab" }],
},
{ timestamps: true, usePushEach: true }
);
LabReportSchema.methods.toLabToJSON = function () {
return {
labReport_id: this._id,
testName: this.testName,
soilLabs: this.soilLabs.SoilToLabJSON(),
};
};
mongoose.model("LabReport", LabReportSchema);
//SoilLab.js
var mongoose = require("mongoose");
var SoilLabSchema = new mongoose.Schema(
{
description: { type: String },
sampleDate: { type: Date },
source: { type: String },
},
{ timestamps: true, usePushEach: true }
);
SoilLabSchema.methods.SoilToLabJSON = function () {
return {
description: this.description,
sampleDate: this.sampleDate,
source: this.source,
};
};
mongoose.model("SoilLab", SoilLabSchema);
When I try to retrieve the LabReport, I get "this.soilLabs.SoilToLabJSON is not a function". This is how I'm trying to retrieve LabReport.
//labReports.js
...
return Promise.all([
LabReport.find()
.populate("soilLabs")
.exec(),
LabReport.count(query).exec(),
req.payload ? User.findById(req.payload.id) : null,
]).then(function (results) {
var labReports = results[0];
var labReportsCount = results[1];
var user = results[2];
return res.json({
labReports: labReports.map(function (labReport) {
return labReport.toLabToJSON(user); //This cant find SoilToLabJSON
}),
If I remove the .SoilToLabJSON in LabReport.js and just call this.soilLabs, it works but outputs all of the soilLabs data which will become an issue when I have the model completed with more data. I have dug into statics vs methods a little and tried changing it to statics but it didn't work.
I get the soilLabs to populate but not sure why the .SoilToLabJSON method is inaccessible at this point. Do I need to find() or populate the soilLab differently? Is the method incorrect?

labReport.toLabToJSON is passing an array and that was causing the error for me. I simply edited the LabReport.js to the following to take the array and map it to SoilToLabJSON properly.
myTestSoilLabOutput = function (soilLabs) {
var test = soilLabs.map(function (soilLab) {
return soilLab.SoilToLabJSON();
});
return test;
Changed the LabReportSchema.methods.toLabToJSON to:
LabReportSchema.methods.toLabToJSON = function () {
return {
labReport_id: this._id,
testName: this.testName,
soilLabs: myTestSoilLabOutput(this.soilLabs),
};
};

How to separate MenuItem method declaration and implementation across different modules in electron.js [duplicate]

I have an Electron app with 3 windows and each window has a different menu. The menu template code for each menu is quite long and I would like to externalize it. So far nothing I have tried works.
I've tried different ways to "modularize" it but got lots of errors. The approach below works to set up the menu, but none of the functions referenced in the menu work (e.g. quitApplication).
Is what I am trying to do not possible or am I just "doing it wrong"?
var test = require("./app/js/menuTest.js");
var tm = new test();
var menuTemplate = tm.getMenu();
myWindow = Menu.buildFromTemplate(menuTemplate);
menuTest.js
function testMenu() {
this.getMenu = function () {
var menuTemplate = [
{
label: global.productData.appName,
submenu: [
{ label: 'About ' + global.productData.appName, click: () => { showAboutWindow() } },
{ type: 'separator' },
{ role: 'hide' },
{ role: 'hideothers' },
{ role: 'unhide' },
{ type: 'separator' },
{ label: 'Quit', click: () => { quitApplication() }, accelerator: 'CmdOrCtrl+q' }
]
// code deleted for clarity
return menuTemplate;
}
}
module.exports = testMenu;

From how I understand your question, you want to move the template code out of your main process script, but keep the functions in there.
This can be achieved by moving the menu structure object into a separate module. The module exports a function that takes an object with references to the functions you want to call in the menu.
I believe this does not add significant complexity and "externalizes" just the menu template code.
menu1.js:
module.exports = function(actions) {
return [
{
label: "Foo",
submenu: [
{ label: "Bar", click: actions.bar },
{ label: "About", click: actions.about }
]
}
];
}
main.js:
const {app,BrowserWindow,Menu} = require("electron");
const actions = {
bar: function () {
console.log("bar");
},
about: function () {
console.log("about");
}
};
const menu1_template = require("./menu1.js")(actions);
const menu1 = Menu.buildFromTemplate(menu1_template);
Menu.setApplicationMenu(menu1);
let mainWindow;
app.on("ready", function() {
mainWindow = new BrowserWindow();
});

how to inherit models.js in pos and make some changes?

models_extend.js
odoo.define('pos_ticket.models_extend', function (require) {
"use strict";
var x = require('point_of_sale.models');
var models = pos_model.PosModel.prototype.models;
models.push(
{
model: 'res.company',
fields: [ 'currency_id', 'email', 'website', 'company_registry', 'vat', 'name', 'phone', 'partner_id' , 'country_id', 'tax_calculation_rounding_method','city','trn_no'],
ids: function(self){ return [self.user.company_id[0]]; },
loaded: function(self,companies){ self.company = companies[0]; },
},
{
model: 'product.product',
fields: ['display_name', 'list_price','price','pos_categ_id', 'taxes_id', 'barcode', 'default_code',
'to_weight', 'uom_id', 'description_sale', 'description',
'product_tmpl_id','tracking','arb'],
order: ['sequence','default_code','name'],
domain: [['sale_ok','=',true],['available_in_pos','=',true]],
context: function(self){ return { pricelist: self.pricelist.id, display_default_code: false }; },
loaded: function(self, products){
self.db.add_products(products);
},
},
{
model: 'product.product',
fields: ['display_name', 'list_price','price','pos_categ_id', 'taxes_id', 'barcode', 'default_code',
'to_weight', 'uom_id', 'description_sale', 'description',
'product_tmpl_id','tracking','arb'],
order: ['sequence','default_code','name'],
domain: [['sale_ok','=',true],['available_in_pos','=',true]],
context: function(self){ return { pricelist: self.pricelist.id, display_default_code: false }; },
loaded: function(self, products){
self.db.add_products(products);
},
}
);
x.Order = x.Order.extend({
export_for_printing: function(){
var self = this;
this.pos = options.pos;
var company = this.pos.company;
var receipt = {
company:{
city:company.city,
trn_no:company.trn_no,
}
}
return receipt;
},
});
I want to add city and trn_no in res.company and arb in product.product to see the arabic translation.Then only i can submit my project in time, i am literally trapped please help me .i am a trainee .
To add new field in POS modules necessary in models.js override PosModel in the parent models which we take from “point_of_sale.models”.
After some changes
odoo.define('pos_ticket.models_extend', function (require) {
"use strict";
var x = require('point_of_sale.models');
var _super = x.PosModel.prototype;
module.PosModel = x.PosModel.extend({
initialize: function (session, attributes) {
// call super to set all properties
_super.initialize.apply(this, arguments);
// here i can access the models list like this and add an element.
this.models.push(
{
// load allowed users
model: 'res.company',
fields: ['city','trn_no'],
domain: function(self){ return [['id','in',self.users.company_id]]; },
loaded: function(self,companies){
console.log(companies);
self.allowed_users = companies;
}
},{
model: 'product.product',
fields: ['arb'],
order: ['sequence','default_code','name'],
domain: [['sale_ok','=',true],['available_in_pos','=',true]],
context: function(self){ return { pricelist: self.pricelist.id, display_default_code: false }; },
loaded: function(self, products){
self.db.add_products(products);
}
},
)
return this;
}
});
});
now i need to inherit another function called "export_for_printing" and add those new fields in it so that i can print these fields.how?

Just add the modifications to the self.models array like this. This works for the version 8. Maybe it you need to adapt it:
if (typeof jQuery === 'undefined') { throw new Error('Product multi POS needs jQuery'); }
+function ($) {
'use strict';
openerp.your_module_name = function(instance, module) {
var PosModelParent = instance.point_of_sale.PosModel;
instance.point_of_sale.PosModel = instance.point_of_sale.PosModel.extend({
load_server_data: function(){
var self = this;
self.models.forEach(function(elem) {
if (elem.model == 'res.company') {
elem.fields = // make your new assignations here
elem.domain = // ...
elem.loaded = // ...
} else if (elem.model == 'product.product') {
// [...]
}
})
var loaded = PosModelParent.prototype.load_server_data.apply(this, arguments);
return loaded;
},
});
}
}(jQuery);

Meteor Handsontables not showing with schema.

Hi there I am trying to use handsontables which works fine when I hard code the data but when I try use a schema which is what i need cant get it to work. I have been following this old post Meteor Handsontable example. I have done everything except change
// Remove "var" from Handsontable declaration to add to global scope
var Handsontable = function (rootElement, userSettings) {
...
// New code
Handsontable = function (rootElement, userSettings) {
...
I cant seem to find this anywhere.
What I have is.
products.js
import { Mongo } from 'meteor/mongo';
import { check } from 'meteor/check';
export const Product = new Mongo.Collection('product');
ProducSchema = new SimpleSchema({
name: {
type: String,
},
m1: {
type: Number,
defaultValue: 0
},
m2: {
type: Number,
defaultValue: 0
},
m3: {
type: Number,
defaultValue: 0
},
m4: {
type: Number,
defaultValue: 0
},
});
Product.allow({
insert: function (userId, doc) {
// the user must be logged in, and the document must be owned by the user
return !!userId;
},
update: function (userId, doc) {
// can only change your own documents
return !!userId;
},
remove: function (userId, doc) {
// can only remove your own documents
return doc.owner === userId;
},
fetch: ['owner']
});
Product.attachSchema( ProducSchema );
productSingle.js
import { Template } from 'meteor/templating';
import { Meteor } from 'meteor/meteor';
import { Product } from '../../../../../api/lists/Products.js';
import './ProductSingle.html';
if (Meteor.isClient) {
Template.ProductSingle.onCreated(function() {
var self = this;
self.autorun(() => {
self.subscribe('product');
})
});
Template.ProductSingle.rendered = function() {
var myData = []; // Need this to create instance
var container = document.getElementById("productSingle");
var hot = new Handsontable(container, { // Create Handsontable instance
data: myData,
startRows: 5,
startCols: 5,
colHeaders: true,
rowHeaders: true,
minSpareRows: 1,
contextMenu: true,
afterChange: function(change, source) { // "change" is an array of arrays.
if (source !== "loadData") { // Don't need to run this when data is loaded
for (i = 0; i < change.length; i++) { // For each change, get the change info and update the record
var rowNum = change[i][0]; // Which row it appears on Handsontable
var row = myData[rowNum]; // Now we have the whole row of data, including _id
var key = change[i][1]; // Handsontable docs calls this "prop"
var oldVal = change[i][2];
var newVal = change[i][3];
var setModifier = {
$set: {}
}; // Need to build $set object
setModifier.$set[key] = newVal; // So that we can assign 'key' dynamically using bracket notation of JavaScript object
MyCollection.update(row._id, setModifier);
}
}
}
});
Tracker.autorun(function() { // Tracker function for reactivity
myData = Product.find().fetch(); // Tie in our data
hot.loadData(myData);
console.log(myData);
});
};
}
This doesn't show any table just the the first row header like so .
If i click on this is get a error:
awsp_handsontable.js?hash=45775ff…:25594 Uncaught Error: column 0 does not exist(…)
If someone could help me figure this out would be great this has been a big road block for me so far

KnockOutJS trigger parent function on child subscribe

I am currently trying to learn KnockOutJS. I thought it would be a great idea to create a simple task-list application.
I do not want to write a long text here, let's dive into my problem. I appreciate all kind of help - I am new to KnockOutJS tho!
The tasks are declared as followed:
var Task = function (data) {
var self = this;
self.name = ko.observable(data.name);
self.status = ko.observable(data.status);
self.priority = ko.observable(data.priority);
}
And the view model looks like this
var TaskListViewModel = function() {
var self = this;
self.currentTask = ko.observable();
self.currentTask(new Task({ name: "", status: false, priority: new Priority({ name: "", value: 0 }) }));
self.tasksArr = ko.observableArray();
self.tasks = ko.computed(function () {
return self.tasksArr.slice().sort(self.sortTasks);
}, self);
self.sortTasks = function (l, r) {
if (l.status() != r.status()) {
if (l.status()) return 1;
else return -1;
}
return (l.priority().value > r.priority().value) ? 1 : -1;
};
self.priorities = [
new Priority({ name: "Low", value: 3 }),
new Priority({ name: "Medium", value: 2 }),
new Priority({ name: "High", value: 1 })
];
// Adds a task to the list
// also saves updated task list to localstorage
self.addTask = function () {
self.tasksArr.push(new Task({ name: self.currentTask().name(), status: false, priority: self.currentTask().priority() }));
self.localStorageSave();
self.currentTask().name("");
};
// Removes a task to a list
// also saves updated task list to localstorage
self.removeTask = function (task) {
self.tasksArr.remove(task);
self.localStorageSave();
};
// Simple test function to check if event is fired.
self.testFunction = function (task) {
console.log("Test function called");
};
// Saves all tasks to localStorage
self.localStorageSave = function () {
localStorage.setItem("romaTasks", ko.toJSON(self.tasksArr));
};
// loads saved data from localstorage and parses them correctly.
self.localStorageLoad = function () {
var parsed = JSON.parse(localStorage.getItem("romaTasks"));
if (parsed != null) {
var tTask = null;
for (var i = 0; i < parsed.length; i++) {
tTask = new Task({
name: parsed[i].name,
status: parsed[i].status,
priority: new Priority({
name: parsed[i].priority.name,
value: parsed[i].priority.value
})
});
self.tasksArr.push(tTask);
}
}
};
self.localStorageLoad();
}
What I want to do in my html is pretty simple.
All tasks I have added are saved to localStorage. The save function is, as you can see, called each time an element has been added & removed. But I also want to save as soon as the status of each task has been changed, but it is not possible to use subscribe here, such as
self.status.subscribe(function() {});
because I cannot access self.tasksArr from the Task class.
Any idea? Is it possible to make the self.tasksArr public somehow?
Thanks in advance!

Try this:
self.addTask = function () {
var myTask = new Task({ name: self.currentTask().name(), status: false, priority: self.currentTask().priority() })
myTask.status.subscribe(function (newValue) {
self.localStorageSave();
});
self.tasksArr.push(myTask);
self.localStorageSave();
self.currentTask().name("");
};
