How do I update the value of a custom attribute (enum-of-strings) in SFCC via code?

Requirement: I want to update the value of a custom attribute (name: badges) (type: enum-of-strings) for a Product via code. I want to set the value "bestSeller" as selected. How should I do that update because the code below is not working?
Screenshot of the Custom Attribute in Business Manager
Code snippet:
function updateBestSeller() {
var ProductMgr = require('dw/catalog/ProductMgr');
var Site = require('dw/system/Site');
var UUIDUtils = require('dw/util/UUIDUtils');
var CustomObjectMgr = require('dw/object/CustomObjectMgr');
var currentSite = Site.getCurrent();
var bestSellerOrderUnits = Object.hasOwnProperty.call(currentSite.preferences.custom, 'bestSellerOrderUnits') ? currentSite.getCustomPreferenceValue('bestSellerOrderUnits') : 0;
try {
Transaction.wrap(function () {
var count = 1;
var products = ProductMgr.queryAllSiteProducts();sni
var HashSet = require('dw/util/HashSet');
var badges = new HashSet();
if (products.count > 0) {
while (products.hasNext() && count < 5) {
var product = products.next();
var badges = [];
badges.push('bestSeller');
if (Object.hasOwnProperty.call(product.custom, 'badges')) {
product.custom.badges = badges
}
count++;
Logger.debug('{0}',product.ID);
}
}
products.close();
});
} catch (ex) {
Logger.error(ex.toString());
return new Status(Status.ERROR, 'ERROR', 'UPDATE failed');
}
return new Status(Status.OK, 'OK', 'UPDATE successful');
}

I think what is probably happening here is that your attempt to validate that a product has a badges key in the product.custom attribute collection is failing. This prevents the update from occurring.
I suggest removing the condition around the following line:
product.custom.badges = badges;
If that line were to not execute, then the update to the database would never occur.
The way custom attributes work is that they will never exist until a value is set for that attribute for a given persistent object. (eg: Product) So checking to see if it exists via something like: 'badges' in product.custom (which is the recommended way) will often be false even when the custom attribute definition exists because many products have never had a badge value set. Once an object has had a value set to a particular custom attribute even if it is now set to null then it will exist.
Additionally, there are some other issues with the code that may be causing problems. One example is defining the badges variable twice within the same scope. Another example is sni that is placed at the end of the line where you define the products variable. This is likely causing an error in your code. Finally, it is a good practice to avoid the use of the queryAllSiteProducts method if you can. An alternative may be to use the ProductSearchModel instead; This may not always meet your need, but it is a good idea to rule it out before resorting to queryAllSiteProducts for performance reasons.
Something else to consider is that if badges currently has any selected values, you'll be overwriting those values with the code you have today. Consider setting badges initially to [] then check to see if there is a value for that product by doing:
if ('badges' in product.custom && !empty(product.custom.badges) {
badges = product.custom.badges;
}

SAPUI5 Javascript - Get first and last elements of array for each unique property

SAPUI5 - I have an array of objects and one of the properties in those is 'Category'.
For example say I have 2 different types of Category, 'Front Shop' and 'Production Area', what I need to do is to be able to get the first value of each and the last value of each, and then set the enabled property of a button as enabled/disabled.
I'm currently using undercore js (_.each) to loop through to perform some other logic, so can include additional logic here.
Not sure if Underscore has a built in function for this?
Or could someone point me in the right direction on how to do this?
I've got my first pass at what was wanted where I get the very first result and the last result, but now need to set this for each unique category.
Example code below:
// Set view data
oViewData.Questions = oQuestions.results;
oViewData.Questions.TotalNumberOfQuestions = oQuestions.results.length;
// Loop Questions, to get Category Desc and Competency Desc values from relevant Sets
_.each(oViewData.Questions, function (result, index) {
// Read and set Category Desc
this.getView().getModel("Survey").read("/CategorySet", {
filters: [new Filter("CategoryId", FilterOperator.EQ, result.CategoryId)],
success: function (oData) {
oViewData.Questions[index]._CategoryDesc = oData.results[0].CategoryDesc;
this.setViewData(oViewData);
}.bind(this),
error: function (oError) {}.bind(this)
});
// Read and set Competency Desc
this.getView().getModel("Survey").read("/CompetencySet", {
filters: [new Filter("CompetencyId", FilterOperator.EQ, result.CompetencyId)],
success: function (oData) {
oViewData.Questions[index]._CompetencyDesc = oData.results[0].CompetencyDesc;
this.setViewData(oViewData);
}.bind(this),
error: function (oError) {}.bind(this)
});
// Set all move up / down buttons to enabled
oViewData.Questions[index]._MoveUpBtn = true;
oViewData.Questions[index]._MoveDownBtn = true;
// if category id is the first one in the list
}.bind(this));
// Overwrite first move up button and last move down btn to disabled
oViewData.Questions[0]._MoveUpBtn = false;
oViewData.Questions.slice(-1)[0]._MoveDownBtn = false;
// Set view data
this.setViewData(oViewData);

First, you can iterate through arrays with native JavaScript.
_.each(array, function(item) {}) is the same as array.forEach(function(item) {}).
Second, you can use the built-in filter function for your actual question:
const aFrontShopItems = oViewData.Questions.filter(function(oItem) {
return oItem.Category === "Front Shop";
}
If oViewData.Questions is an array then the function passed to filter is applied to every element. If the condition (e.g. oItem.Category === "Front Shop") is true then the element is added to the new array aFrontShopItems. Obviously you need to call filter a second time to get the Production Area items. You can then apply your logic to the first and last items of your new arrays.

How to get value in Js of other field that is passed to widget? Odoo

I created a widget which fills some fields automatically. Basically I am checking some values from google maps geolocate and filling other fields depending on what those values are. Turned out I need to check one value that is already in my form. What happens at the moment I get only value that was saved before and if it changes I still get the old value. My question if how to get that value real-time?
My code is something like this:
var gmap_autocomplete = form_common.AbstractField.extend({
// functions such as start, init, on_ready...
setFields : function (fieldName, fieldValue) {
var not_vat_payer = this.view.datarecord[this.node.attrs.check_not_vat]);
// Here I get the value that I want of previous form save
// for example if value was true, I came here and triggered this
//widget I will get value true, but if I change it to false
// I will still get true value of previous save
}
});
My field with widget looks like this:
<field name="not_vat2"/>
<field name="autocomplete" class="autoc" widget="gmap_autocomplete" street="street"
city="city" zip="zip" country_id="country_id" lang="lang" invoice_lang="invoice_lang"
property_account_payable_id="property_account_payable_id"
property_account_receivable_id="property_account_receivable_id"
check_not_vat="not_vat2"/>

Found the solution which is really simple:
This will return field value which is in view no matter its stored in db or not.
this.field_manager.get_field_value('field_name');

exmple.js
Make changes something like..
var model_obj = new Model('model.name');
var gmap_autocomplete = form_common.AbstractField.extend({
// functions such as start, init, on_ready...
setFields : function (fieldName, fieldValue) {
var not_vat_payer = this.view.datarecord[this.node.attrs.check_not_vat]);
new_val = false;
model_obj.call('method_name',[new_val]).then(function(result){});
}
});
example.py
#api.model
def method_name(self,new_val):
//write code for change field value

How to filter out usercreated events in fullcalendar

I have a fullcalendar where I display non-editable events which are collected from a google calendar, or from a database. Then I want to register customer requests for events from the calendar. This works, but I am not able to list only the events that are added by the user.
Any hint on how to do this?
I tried this:
function retrieve_events() {
var rdv=$('#calendar').fullCalendar( 'clientEvents', undefined);
for (i=0; i<=rdv.length-1; i++) {
/*alert(rdv.toSource());*/
alert(rdv[i].title+" id: "+rdv[i].id+" start: "+rdv[i].start+" end:"+rdv[i].end+" heldag:"+rdv[i].allDay);
}
}
The the "undefined" as id, means that I have given all the non-editable events an id, while the new ones haven't got one. But this way I get all events listed, even those without an id. The same happens with null and ''. But using hardcoded id-numbers returns that specific event.
I see from the documentation that there seems to be other ways to get hold of the events I need, by using other criteria like classes. However I cannot figure out how to specify this filter.

I haven't worked with FullCalendar yet nor do I intend to extensively test this, so I cannot guarantee that this will work.
However, why don't you simple test whether rdv[i].id evaluates to false?
Try:
function retrieve_events( ) {
var rdv = $('#calendar').fullCalendar('clientEvents'),
results = [];
for( var i = 0; i < rdv.length; ++i ) {
if( !rdv[i].id ) {
results.push(rdv[i]);
}
}
return results;
}
P.S.: Passing undefined to .fullCalendar() probably is redundant. It would be equivalent to passing only a single variable. I'd guess the second parameter is a type of events that you can filter for, but passing only a single parameter would cause the plugin to return all events. Also, note that !!'' === false.
The internal check whether the second parameter is set is probably similar to this:
$.fn.fullCalendar = function( command ) {
switch( command ) {
// ... some case's
case 'clientEvents':
var filter = arguments[1];
if( !filter ) {
// Retrieve ALL client events
}
else {
// Filter client events
}
break;
// ... some more case's
}
};
This does not compare types. Testing filter === false would only return true, if filter would evaluate to false and is a boolean.
Following are examples of values that evaluate to false. There may be more, but I believe those are all.
undefined
null
0
false
''

Javascript populate form after validation

I am doing a form for my javascript class, and I am getting stuck on a certain portion of it. I have a separate validator javascript file and call the function on the html file. All the validation works if the form areas are not filled in. What I want to do is if the fields are left blank they will fail the validation and will insert a value into that field. Below are an example of the form field, javascript function in the html page, and the external validator js file.
call function in html head:
function formvalidation(thisform) {
with (thisform) {
if (textbox_validation(first_name,"Please enter your first name.")==false)
{first_name.blur(); return false;};
if (textbox_validation(business_name,"Please enter your business. Please enter N/A if
you do not have one.")==false) { business_name.focus(); return false;
business_name.value=="N/A";};
The external js validator:
function textbox_validation(entered, alertbox) {
with (entered) {
if (value==null || value=="") {
alert(alertbox);
return false;
}
else {
return true;
}
}
}
So the validator works and focuses on the empty fields, but for some of my fields I want them to fill themselves with a certain value if validation fails or if it isnt filled int. The business_name line of code is when I tried to make it work. Any help is much appreciated!

Ordinarilly, you wouldn't use alert, but would instead put error messages in a span or div either near the input or at the top (or bottom) of the form. Additionally (as mentioned by #Frits van Campen) it is generally bad practice to use with
Try something like this instead:
function textbox_validation(entered, errormsg) {
var errbox = document.getElementById(entered.id + '-errors'); // just to prevent writing it twice
// Note this requires the input to have an id, and the errer box's id to be the same with an '-errors' suffix.
// Instead of using with, just acces properties normally
if (!entered.value) { // The `!` "neggation" operater makes "falsy" values `true`
// "falsy" values include `false`, the empty string, `0`, `null`, `undefined`, `NaN` and a few others
// Put the error message in the DOM instead of alerting it
errbox.innerHTML = errormsg;
return false;
}
else {
// Wipe any previous error messages
errbox.innerHTML = '';
return true;
}
}
And for the form validator, again; let's not use with. But also, when attempting to assing "N/A" to the value, you've used the comparison operator instead of the assignment operator, and you've done it after returning:
function formvalidation(thisform) {
// just use the `!` "negation" operator
if (!textbox_validation(thisform.first_name,
"Please enter your first name."))
{
thisform.first_name.blur();
return false;
}
if (!textbox_validation(business_name,
"Please enter your business. Please enter N/A if you do not have one."))
{
thisform.business_name.focus();
thisform.business_name.value = "N/A"; // for assignment, use `=`. `==` and `===` are used for comparison
return false; // a return statement ends the function, make sure it's after anything you want to execute!
}
}

Use the DOM to set the placeholder for the fields. Like this.
var myInput = document.getElementById('input1');
myInput.placeholder = 'This validation has failed.';
