Javascript identifier for widget in Odoo

If you have two widget in a view. And you do something with the first widget and you want to update (call display_field) the second widget. How to have the identifier for the second widget?
For example in the extend definition of a widget:
local.FieldNewWidget = instance.web.form.AbstractField.extend({
init: function(parent, options) {
},
events: {
'click .oe_new_input_button': 'open_new_specific_form',
},
start: function() {
},
display_field: function() {
},
render_value: function() {
},
open_new_specific_form: function(event) {
var self = this;
var new_action = {
type: 'ir.actions.act_window',
name: $(event.target).data('name'),
res_model: $(event.target).data('data-model'),
res_id: $(event.target).data('res-id'),
view_mode: 'form',
view_type: 'form',
views: [[false, 'form']],
target: 'new',
context: {
},
flags: {'form': {'action_buttons': true}},
}
self.do_action(new_action, {
on_close: function() {
// I want to refresh (call display_field) the second widget here.
// What is the identifier for the second widget?
},
});
},
});

i think this will work but i don't know if it's the best solution. I think every widget knows witch view it's by using (this.view). why don't you use a special event to trigger it from one widget and listen for it in the other one.
For example Register an event listener on the widget to listen for property changing on the view:
//in first widget register the event listener:
this.view.on('property_name', this, this.your_method);
// in second widget trigger the event by setting the value
this.view.set('property_name', a_value);
i'm new to odoo javascript let me know if this works for you i think there is a better solution by using events triggering without changing properties at all.

Listen to custom event in Vue.js

Vue.js works great with browser events such as click or mousedown. But not work at all with custom events. Here is the code:
HTML:
<div id="app" style="display: none" v-show="true">
<div v-el:ping v-on:ping="ping">
<div>
<button v-on:click="click">Click</button>
</div>
</div>
</div>
JavaScript:
new Vue({
el: '#app',
data: {
},
methods: {
ping: function (event) {
console.log('Vue ping', event);
alert('Vue ping');
},
click: function (event) {
jQuery(event.target).trigger('ping');
}
},
ready: function () {
console.log(this.$els);
jQuery(this.$els.ping).on('ping', function (event) {
console.log('jQuery ping', event);
alert('jQuery ping');
});
}
});
I expect alert with Vue ping and jQuery ping. But only the later pops up.
CodePen

Vue has its own internal system for custom events, which you should use instead of jQuery / native DOM events:
click: function (event) {
// jQuery(event.target).trigger('ping');
this.$dispatch('ping', event.target) // send event up the parent chain, optionally send along a reference to the element.
// or:
this.$emit('ping') // trigger event on the current instance
}
Edit: $dispatch is for parent-child communication, You seem to want to trigger a custom event from within the same comonent. In that case, you could instead simply call a method.
If you still want to listen to a custom event inside the same component, you:
want to use $emit
cannot use v-on:custom-event-name in the template (that's only to be used on components). Rather, add the event method to the events::
events: {
ping: function() {....}
}

Here it is in vanilla JS:
HTML:
<div id="app">
<div v-el:ping>
<div>
<button v-on:click="click">Click</button>
</div>
</div>
</div>
JS:
(function() {
new Vue({
el: '#app',
data: {
event: null
},
methods: {
ping: function(event) {
alert('Vue ping');
},
click: function(event) {
this.$els.ping.dispatchEvent(this.event);
}
},
ready: function() {
this.event = document.createEvent("HTMLEvents");
this.event.initEvent("ping", true, true);
this.$els.ping.addEventListener('ping', this.ping);
}
});
})();

You should avoid to mix a dom events and vue-components related ones because it's a different layers of abstraction.
Anyway, if you still want to do that, I think you need to cache this.el inside a vue-component instance or take it via computed-property like this
{
computed : {
jqueryEl(){ return $(this.el) }
}
}
And then trigger a custom jQuery events by this.jqueryEl.trigger('ping').
Sure to properly take care of keep the element's bindings up to date!
For example you can bind jQuery events dynamically (and also unbind on component destroy!) like this:
ready : function(){
jQuery('body').on('ping.namespace', '[data-jquery="ping"]', function(){ ... })
},
destroy : function(){
jQuery('body').off('ping.namespace')
}
And don't forget to add attribute [data-jquery="ping"] to an element which you would like to response a ping event.
Hope this information helps you to achieve the expected result.

VueJS and tinyMCE, custom directives

I've been struggling hard with getting VueJS and TinyMCE to work together. I've come to the conclusion that using directives would be the way to go.
So far I've been able to pass in the body as a directive parameter, and tinyMCE sets the content. However, I can't get the two way binding to work. I'm also afraid that I'm doing things completely wrong based on the tinyMCE api.
The relevant tinyMCE functions I assume would be:
http://community.tinymce.com/wiki.php/api4:method.tinymce.Editor.setContent
// Sets the content of a specific editor (my_editor in this example)
tinymce.get('my_editor').setContent(data);
and
http://community.tinymce.com/wiki.php/api4:method.tinymce.Editor.getContent
// Get content of a specific editor:
tinymce.get('content id').getContent()
HTML
<div id="app">
<h3>This is the tinyMCE editor</h3>
<textarea id="editor" v-editor :body="body"></textarea>
<hr>
<p>This input field is properly binded</p>
<input v-model="body">
<hr>
<pre>data binding: {{ body }} </pre>
</div>
JS
tinymce.init({
selector:'#editor',
});
Vue.directive('editor', {
twoWay: true,
params: ['body'],
bind: function () {
tinyMCE.get('editor').setContent(this.params.body);
tinyMCE.get('editor').on('change', function(e) {
alert("changed");
});
},
update: function (value) {
$(this.el).val(value).trigger('change')
},
});
var editor = new Vue({
el: '#app',
data: {
body: 'The message'
}
})
Fiddle
https://jsfiddle.net/nf3ftm8f/

With Vue.js 2.0, the directives are only used for applying low-level direct DOM manipulations. They don't have this reference to Vue instance data anymore. (Ref: https://v2.vuejs.org/v2/guide/migration.html#Custom-Directives-simplified)
Hence I recommend to use Component instead.
TinymceComponent:
// Use JSPM to load dependencies: vue.js 2.1.4, tinymce: 4.5.0
import Vue from 'vue/dist/vue';
import tinymce from 'tinymce';
// Local component
var TinymceComponent = {
template: `<textarea class="form-control">{{ initValue }}</textarea>`,
props: [ 'initValue', 'disabled' ],
mounted: function() {
var vm = this,
tinymceDict = '/lib/jspm_packages/github/tinymce/tinymce-dist#4.5.1/';
// Init tinymce
tinymce.init({
selector: '#' + vm.$el.id,
menubar: false,
toolbar: 'bold italic underline | bullist numlist',
theme_url: tinymceDict + 'themes/modern/theme.js,
skin_url: tinymceDict + 'skins/lightgray',
setup: function(editor) {
// If the Vue model is disabled, we want to set the Tinymce readonly
editor.settings.readonly = vm.disabled;
if (!vm.disabled) {
editor.on('blur', function() {
var newContent = editor.getContent();
// Fire an event to let its parent know
vm.$emit('content-updated', newContent);
});
}
}
});
},
updated: function() {
// Since we're using Ajax to load data, hence we have to use this hook because when parent's data got loaded, it will fire this hook.
// Depends on your use case, you might not need this
var vm = this;
if (vm.initValue) {
var editor = tinymce.get(vm.$el.id);
editor.setContent(vm.initValue);
}
}
};
// Vue instance
new Vue({
......
components: {
'tinymce': TinymceComponent
}
......
});
Vue Instance (simplified)
new Vue({
el: '#some-id',
data: {
......
description: null
......
},
components: {
'tinymce': TinymceComponent
},
methods: {
......
updateDescription: function(newContent) {
this.description = newContent;
},
load: function() {
......
this.description = "Oh yeah";
......
}
......
},
mounted: function() {
this.load();
}
});
HTML (MVC view)
<form id="some-id">
......
<div class="form-group">
<tinymce :init-value="description"
v-on:content-updated="updateDescription"
:id="description-tinymce"
:disabled="false">
</tinymce>
</div>
......
</form>
The flows
First the data is loaded through remote resources, i.e., AJAX. The description got set.
The description got passed down to the component via props: initValue.
When the component is mounted, the tinymce is initialized with the initial description.
It also sets up the on blur event to get the updated content.
Whenever the user loses focus on the editor, a new content is captured and the component emits an event content-updated, letting the parent know that something has happened.
On Html you have v-on:content-updated. Since the parent is listening to the content-updated event, the parent method updateDescription will be called when the event is emited.
!!Couple Important Notes!!
By design, the component has 1 way binding, from parent to component. So when the description gets updated from Vue instance, the component's initValue property should be updated as well, automatically.
It would be nice if we can pass whatever the user types in tinymce editor back to the parent Vue instance but 2 ways bindings is not supposed. That's when you need to use $emit to fire up events and notify parents from components.
You don't have to define a function in parent and do v-on:content-updated="updateDescription". You can just directly update the data by doing v-on:content-updated="description = $event". The $event has the parameter you defined for the function inside the component - the newContent parameter.
Hope I explained things clearly. This whole thing took me 2 weeks to figure it out!!

Here's a Tinymce component for Vue.
http://jsbin.com/pucubol/edit?html,js,output
It's also good to know about v-model and custom input components:
https://v2.vuejs.org/v2/guide/components.html#Form-Input-Components-using-Custom-Events
Vue.component('tinymce', {
props: ['value'],
template: `<div><textarea rows="10" v-bind:value="value"></textarea></div>`,
methods: {
updateValue: function (value) {
console.log(value);
this.$emit('input', value.trim());
}
},
mounted: function(){
var component = this;
tinymce.init({
target: this.$el.children[0],
setup: function (editor) {
editor.on('Change', function (e) {
component.updateValue(editor.getContent());
})
}
});
}
});
<tinymce v-model="whatever"></tinymce>

Try this:
Vue.directive('editor', {
twoWay: true,
params: ['body'],
bind: function () {
tinyMCE.get('editor').setContent(this.params.body);
var that = this;
tinyMCE.get('editor').on('change', function(e) {
that.vm.body = this.getContent();
});
}
});
The trick was storing the directive in the temporary variable "that" so you could access it from within the change event callback.

There is now an npm package which is a thin wrapper around TinyMCE, making it easier to use in a Vue application.
It is open source with code on GitHub.
Installation:
$ npm install #tinymce/tinymce-vue
Usage:
import Editor from '#tinymce/tinyme-vue';
Templates:
<editor api-key="API_KEY" :init="{plugins: 'wordcount'}"></editor>
Where API_KEY is your API key from tiny. The init section is the same as the default init statement except you do not need the selector. For an example see the documentation.

Backbone nested view has events which are not triggering

Okay so I have a parent view which has a click event which renders a child view. Within this child view is a form which I'm trying to validate and then submit. So my parent view looks something like this:
var MapView = Backbone.View.extend({
el: '.body',
template: _.template(MapTemplate),
render: function() {
...
},
events: {
'click #log-pane-title': 'loadLogView'
},
loadLogView: function() {
var eventLogView = new EventLogView({
id: properties._id
});
eventLogView.render();
}
});
And my child view looks something like this:
var EventLogView = Backbone.View.extend({
el: '#eventlog',
logform: new NewLogForm({
template: _.template(AddLogTemplate),
model: new LogModel()
}).render(),
render: function() {
// Render the form
$("#addtolog").html(this.logform.el);
},
events: {
'submit #addlogentry': 'test'
},
test: function() {
alert('inside eventlogview');
return false;
}
});
The problem I'm facing is that test() never fires. For debugging purposes I made sure the submit event was even firing by putting:
$('#addlogentry').on('submit', function() {
alert( "submit firing" );
return false;
});
In render() of the EventLogView. That does actually trigger, so I'm not sure what's going on and why test() isn't triggering.

To avoid scoping issues all the events delegation are scoped to the views el in Backbone.
So your #addlogentry button should live inside your EventLogView el.
And your sanity check in the render should look something like this to mimic how Backbone works internally :
this.$el.on('submit', '#addlogentry', function() {
alert( "submit firing" );
return false;
});

Sencha Touch - Calling function within view does not get called

Ive just started to explore sencha. Stuck up with this. Help Appreciated :)
This is my java script code, in the below line handler function i am calling the following the method, which in under items and parent xtype form-panel.
{
xtype:'panel',
defaults:{
xtype:'button',
style:'margin: 0.1em',
flex:1
},
layout:{
type:'hbox',
align:'center'
},
items:[
{
text:'Submit',
handler:this.makeReq,
scope:this
},
{
text:'Terms & Conditions',
}
]
}
This is the method that am calling in the above function, but it seems does not happen anyting.
makeReq: function() {
alert("Hey There");
}

I really suggest you follow the Sencha Touch 2 MVC model in this case. You can give your button an action like this:
{
text:'Submit',
action: 'submit'
}
Then you can refer this button and set the function for it inside your app's controller:
config: {
refs: {
submitButton: 'button[action=submit]',
},
control: {
submitButton: {
tap: 'makeReq'
},
},
makeReq: function() {
alert("Hey There");
}
}
