Front-End .. dialog collection render template

[item]

Hi,

i little learn front-end but here i loose
un custom modal view..
this open, template is rendered normaly..
if you see code, commented, if i uncomment the hard coded nomenclatureList, the template "content" is ok.

Here my goal is render the template after collection.fetch.
the value is retreived from back-end in the this.listenTo(collection, 'sync', (collection, response, options) => { ...

but i can not pass the value and render the dialog.

Any front-end specialist ?

define('custom:views/meeting/modals/dialog-care-nomenclature', ['views/modal', 'model', 'collection'], function (Dep, Model, Collection) {

    return Dep.extend({

A print-screen for better understand.

Hello item

At first sight it looks like you need to modify this:

FROM:

                val.forEach(function (item) {
                    nomenclatureDataList.push(item);
                });
​ 

TO:

                val.forEach(function (item) {
                    this.nomenclatureDataList.push(item);
                });
​ 

write this.nommenclatureDataList.push(item) instead of nommenclatureDataList.push(item)

I did not test it but it should work.

Best Regards

Hi @telecastg,
i have tested but no luck
Uncaught TypeError: Cannot read properties of undefined (reading 'push')

i have to try outside :
let nommenclatureDataList = [];

first problem :
i can't not find the var nommenclatureDataList in the val.foreach

second problem :
if you see print-screen.. consol.log('SETUP END') is printed before collection.fetch
in this situation, i think the template is rendered before collection.fetch.

I think, the template must be rendered after collection.fetch and set nommenclatureDataList

Hope this can useful for resolve my problem.

[yuri]

Context lost. Use an arrow function:

val.forEach(item => this.nomenclatureDataList.push(item));​​

No. It's not rendered before fetch. Setup is ended before fetch. Fetch is async and rendering is deferred until fetch is complete.

[item]

Thank you Yuri,
perfect.

[telecastg]

Let's try this way to solve the first problem:

            this.listenTo(collection, 'sync', (collection, response, options) => {

                let val = response.list;

                val.forEach(function (item) {
                    this.nomenclatureDataList.push(item);
                }.bind(this));
                
                this.reRender();
                
            }); 

I don't think that the template is being rendered before the collection is fetched as the "wait" statement should be preventing that.

https://docs.espocrm.com/development/view/#waiting-for-some-data-loaded-before-rendering

The reason why the console.log statement is showing is because the statement is invoked without having to wait for the template to be rendered.

Hi telecastg ..

in custom view of meeting i have this

setup: function () {
            Dep.prototype.setup.call(this);
        },​
...

events: {
            'click [data-action="attendee-care"]': function (e) {​
...
       }, 

Hum, i just realise that my above "events" .. kill the events of duplicate.

but if you look : https://github.com/espocrm/documenta...725b8d58106338

so i writed :

setup() {    
     super.setup();        
     this.events['click [data-action="attendee-care"]'] = (e) => {        
         console.log(e);
    };    
},  ​ 

i have try with the doc of Yury, here above.. but he say : Uncaught TypeError: TypeError: (intermediate value).setup is not a function

Any help ?

[telecastg]

Hi item,

I would try the "traditional" way like this:
setup() {

Dep.prototype.setup.call(this);
...

this.events['click [data-action="attendee-care"]'] = (e) => {
console.log(e);
};

....
}

If the traditional syntax is not working, one "low tech" solution could be to simply copy all events from the prototype view.

The "super" keyword/function is part of the ECMAScript syntax, and only applies if a standard AMD Espo module (traditional) has been refactored into an ECMAScript Module and Class.

For ECMAScript classes, the keyword "super" is equivalent to "prototype" in plain vanilla Javascript and in Espo AMD module implementation.

So, unless the particular script that you are trying to customize has been refactored from AMD to ECMAScript the instruction Dep.prototype.setup.call(this); should work.

"Dep.prototype.setup"

I read this exact same thing on Git today!

Anyway this will be consider old legacy code soon with the upcoming UI code call EMS (???). But at least there is a promise of "Life-time backward compatibility" so not all is lost even if you do end up using this code?
