Changing isOpen property in route should reflect it in my component. How can we accomplish this ?.
Ember-Twiddle
routes/application.js
import Ember from 'ember';
export default Ember.Route.extend({
isOpen:true,
setupController(controller,model){
this._super(...arguments);
controller.set('isOpen',this.get('isOpen')); //whenever i set route property, will this update controller?
console.log('setupController');
},
actions:{
toggleOpen(){
console.log('before toggle - ',this.get('isOpen'));
this.toggleProperty('isOpen'); //changing this route property is not reflected in controller.
//this.controller.toggleProperty('isOpen'); //changing controller is reflecting.
console.log('after toggle - ',this.get('isOpen'));
}
}
});
controllers/application.js
import Ember from 'ember';
export default Ember.Controller.extend({
appName: 'Ember Twiddle'
});
templates/application.hbs
<h1>Welcome to {{appName}}</h1>
<br>
{{isOpen}}
{{my-component isOpen=isOpen toggleOpen='toggleOpen'}}
<br>
{{outlet}}
<br>
<br>
templates/components/my-component.hbs
my-component {{isOpen}}
<button {{action 'toggleOpen'}}> Toggle </button>
{{yield}}
components/my-component.js
import Ember from 'ember';
export default Ember.Component.extend({
actions:{
toggleOpen(){
this.sendAction('toggleOpen');
}
}
});
Because isOpen is a primitive typed property. No matter if it was an object. Sample Twiddle.
Or more simplistic one.

How can we get the original event in ember action while handling action inside controller?
Controller
import Ember from 'ember';
export default Controller.extend({
showDetails:function(id)
{
// I want like $(this).position().top
}
});
Template
{{#each item in list}}
<em {{action "showDetails" item.id bubbles=false}}></em>
{{/each}}
{{#each item in list}}
<em onclick={{action "showDetails" item.id}}></em>
{{/each}}
In controller,
import Ember from 'ember';
export default Controller.extend({
actions: {
showDetails(id, event) {
//i want like $(this).position().top
}
}
});
I have a component that has a text field, like this
<div>
{{input type='text' insert-newline='postMessage' class="form-control" autofocus="true"}}
<input type="hidden" name="uid" value={{room.uid}}/>
</div>
the component that have this snippet, lives inside a route called room
export default Ember.Route.extend({
model(params){
this.store.findRecord('room', params.uid);
}
});
to handle the action in the input, I created a controller for the room:
app/controllers/room.js
import Ember from 'ember';
export default Ember.Controller.extend({
actions: {
postMessage(params){
console.log(params);
}
}
});
but when I hit enter, I get this error:
Uncaught Error: <chathub-ember#component:chat-room::ember1071> had no action handler for: postMessage
I tried to put this action in the route as well and didn't worked
In the room.hbs file,
{{my-component myAction='postMessage'}}
and then in my-component.js
import Ember from 'ember';
export default Ember.Component.extend({
actions: {
postMessage(params) {
this.sendAction('myAction', params);
}
}
})
test-component.js
import Ember from 'ember';
export default Ember.Component.extend({
store: Ember.inject.service(),
showLang: Ember.on('init', function() {
var store = this.get('store');
return store.findAll('language');
}),
});
I checked with console and yes they show
XHR finished loading: GET "http://127.0.0.1:8000/languages".
So backend recognize my test-component function.
Now in test-component.hbs I have
{{#each showLang as |lang| }}
<li>{{lang.title}}</li>
{{/each}}
The result was empty. How can I do so data could show up in test-component.hbs?
First of all - you should do it in route and pass data as model to component, but if you really want to do this in component you can do so:
test-component.js:
import Ember from 'ember';
export default Ember.Component.extend({
store: Ember.inject.service(),
showLang: Ember.on('init', function() {
this.get('store').findAll('language').then(languages => this.set('languages', languages));
})
});
test-component.hbs:
{{#each languages as |lang| }}
<li>{{lang.title}}</li>
{{/each}}
My click-editable component like:
Template:
{{#if isEdit}}
<div class="input-group">
{{input type="text" value=editValue class="form-control"}}
<div class="input-group-btn">
<button type="button" class="btn no-margin-btn btn-info" {{action "updateValue"}}>{{fa-icon 'check'}}</button>
</div>
</div>
{{else}}
....
{{/if}}
And:
export default Ember.Component.extend({
tagName: "",
isEdit: false,
canEdit: true,
category: 'input',
editValue: Ember.computed.oneWay('value'),
actions:{
updateValue() {
this.sendAction('onUpdate', this.get('valueModel'), this.get('valueColumn'), this.get('editValue'), this.get('isEdit'));
}
}
});
Use in my template:
{{#each model.quotationWorkItems as |quotationWorkItem index|}}
{{click-editable valueModel=quotationWorkItem valueColumn='name' value=quotationWorkItem.name onUpdate=(action "updateInput")}}
{{/each}}
In the controller:
import Ember from 'ember';
export default Ember.Controller.extend({
....
actions: {
updateInput(updateModel, updateColumn, value, isEdit) {
updateModel.set(updateColumn, value);
updateModel.save().then(()=> {
this.get('model').reload();
this.set('isEdit', false);
}, ()=> {
alert('wrong');
});
}
}
})
Route:
import Ember from 'ember';
export default Ember.Route.extend({
...
model(params) {
return this.store.find('quotation', params.quotation_id);
},
setupController(controller, model) {
controller.set('model', model);
...
}
})
Quotation model:
import DS from 'ember-data';
export default DS.Model.extend({
quotationStocks: DS.hasMany('quotationStock'),
quotationWorkItems: DS.hasMany('quotationWorkItem'),
...
});
QuotationWorkItem model:
import DS from 'ember-data';
export default DS.Model.extend({
transactionType: DS.belongsTo('transactionType'),
quotation: DS.belongsTo('quotation'),
...
});
This code can update model value, but problem isEdit is the component value. When isEdit send to controller and set another value, it can not work. So I think can not change component value in ember controller?
this.set('isEdit', false);
The code can not work in controller. I'm using Ember 2.4.0.
You need to bind the controller isEdit property to the component isEdit property.
{{click-editable isEdit=isEdit valueModel=quotationWorkItem valueColumn='name' value=quotationWorkItem.name onUpdate=(action "updateInput")}}
This will overwrite the isEdit property in the component (data down).
I'm trying to create a modal for my users to signin, so I have this link:
<li><a {{action "signin"}}>Sign In</a></li>
in a {{planhw-navbar}} component.
{{planhw-navbar signin=(action "showModal" name="signin-modal")}}
But when I open my browser, I get the error:
An action named 'showModal' was not found in (generated application controller)
I've tried putting an action in a controller, a route, and a component:
import Ember from 'ember';
export default Ember.Component.extend({
actions: {
showModal: function(name) {
this.render(name, {
into: 'application',
outlet: 'modal'
});
}, //...
}
})
My component, {{signin-modal}}, works correctly.
My entire application.hbs:
{{planhw-navbar signin=(action "showModal" name="signin-modal")}}
{{outlet}}
{{outlet 'modal'}}
You need to add an action called showModal in your application.js controller.
