Component action triggers perfectly.
import Ember from 'ember';
export default Ember.Component.extend({
actions: {
searchField: function() {
console.log('searchField');
this.sendAction('searchField');
}
}
});
Route does not get triggered.
import Ember from 'ember';
export default Ember.Route.extend({
actions: {
searchField: function() {
console.log('ROUTE');
}
}
});
Handlebars
{{input key-up='searchField' searchField=(action "searchField")}}
I have spent so much time with this I am starting to lose interest with Ember.js, as I have also tried according to the documentation, but I get the same result.
http://emberjs.com/api/classes/Ember.Component.html#method_sendAction
sendAction will not reach to route.
You have two options,
define searchField function in controller and from there you can route functionthis.send('searchField')
To directly call from component to route, there is addon ember-route-action-helper for this.
ember install ember-route-action-helper

Pretty new to Ember so maybe someone can help me out. I keep running across this error and have no idea how to solve it.
Ember : 2.5.1
Ember Data : 2.5.3
Below is my router.js.
//app/router.js
import Ember from 'ember';
import config from './config/environment';
const Router = Ember.Router.extend({
location: config.locationType
});
Router.map(function() {
this.route('organization', {path: '/organization/:id'}, function(){
this.route('about', { path: '/about' });
this.route('admin', { path: '/admin' }, function(){
this.route('team', { path: '/team/:team_id' });
});
});
});
The organization/:id/about and organization/:id/admin routes work fine. But when I try to load the organization/:id/admin/team/:team_id route, the error is thrown. Below is the routes/organization/admin/team.js file:
//app/routes/organization/admin/team.js
import Ember from 'ember';
export default Ember.Route.extend({
model(params) {
let organization = this.modelFor('organization');
return organization.get('team');
}
});
Not really sure what other information I should post, so please ask for any additional information you may think is necessary to help debug. My guess is it's something pretty simple and I'm completely oblivious to it.
EDIT
I've added a couple more files to help diagnose the problem:
//app/routes/organization.js
import Ember from 'ember';
export default Ember.Route.extend({
model(params) {
return this.store.findRecord('organization', params.organization_id)
}
});
//app/routes/organization/admin.js
import Ember from 'ember';
export default Ember.Route.extend({
actions: {
changeValue(){
this.currentModel.save();
}
}
});
Where currentModel is the model for the organization route. I've removed the organization.admin.team model hook for now and am just testing a
{{#link-to 'organization.admin.team' model.team.id}} Team {{/link-to}}
in a component rendered in the organization.admin template where I pass model=model. But now I get the same error (Assertion Failed: You need to pass a model name to the store's modelFor method) in the Javascript console when rendering the organization.admin template.
If you pass Object to {{#link-to}} helper. It skips the model hook. So you could basically send {{#link-to 'team' organization.team}}Without having to write "model" hook.
"It makes sense and it might save a request to the server but it is, admittedly, not intuitive. An ingenious way around that is to pass in, not the object itself, but its id" - https://www.toptal.com/emberjs/the-8-most-common-ember-js-developer-mistakes".
So you should do
hbs
{{#link-to 'team' organization.team.id}} Link to team management {{/link-to}}
route
model(params) {
return this.store.findRecord('team', params.team_id)
}
you can use modelFor('parent') method to get organization model.
like that
//app/routes/organization/admin/team.js
import Ember from 'ember';
export default Ember.Route.extend({
model(params) {
let organization = this.modelFor('parent');
return this.store.findRecord('team', params.team_id)
}
});
i think you wants to do something like that.
basically ember does not support nested routes.
I have a custom component that I'd like to attach a user interaction action to:
pro-form-price-field{action 'saveCatalogTicket' ticket on='focus-out'} currency="usd" value=ticket.base_price class='inline-field inline-field-medium'
This fails to compile. Any ideas to how I can attach an onFocusOut to a custom component?
Just place focusOut function in pro-form-price-field.js file.
import Ember from 'ember';
const { on } from Ember;
export default Ember.Component.extend({
focusIn(){
},
// or as Thernys pointed out use on event.
saveCatalogTicket: on('focusOut', function(){
})
});
I'm trying to set queryParams in an Ember controller, but they don't seem to be updating the URL at all.
I have this abbreviated mixin being applied to the route:
import Ember from 'ember';
import ControllerPaginationMixin from './controller-pagination';
export default Ember.Mixin.create({
setupController(controller, model) {
this._super(controller, model);
controller.reopen(ControllerPaginationMixin);
}
});
And here's the abbreviated controller mixin that is applied above:
import Ember from 'ember';
export default Ember.Mixin.create({
sortKey: null,
queryParams: ['sortKey'],
actions: {
sort(key) {
this.set('sortKey', key);
}
});
When I call the sort method from a component, I can see in the Ember Inspector that the sortKey property has been changed to the correct new value, but the URL remains unchanged. Am I missing something?
Your problem is that you're trying to customize the controller class at the runtime.
You will reopen the controller every time a user visits the route, that's ridiculous.
Simply extend the controller definition with the mixin and you're good to go.
I have an ember application with a controller header.js and a template header.hbs.
Now I have some javascript I need to execute at document $( document ).ready()
I saw on Ember Views there is didInsertElement but how do I do this from the controller?
// controllers/header.js
import Ember from 'ember';
export default Ember.Controller.extend({
});
// views/header.js
import Ember from 'ember';
export default Ember.Controller.extend({
});
// templates/header.js
test
I read several times it's not good practice to be using Ember Views?
the controller is not inserted (the view is) hence there is no didInsertElement.
If you need something to run once, you can write something like this:
import Ember from 'ember';
export default Ember.Controller.extend({
someName: function () { // <--- this is just some random name
// do your stuff here
}.on('init') // <---- this is the important part
});
A more actual answer (Ember 2.18+) while honouring the same principle as mentioned in user amenthes' answer: it's no longer advised to use Ember's function prototype extensions. Instead you can override the init() method of a controller directly. Do note that you'll have to call this._super(...arguments) to ensure all Ember-related code runs:
import Controller from '#ember/controller';
export default Controller.extend({
init() {
this._super(...arguments); // Don't forget this!
// Write your code here.
}
});
I am using Ember's Need Api to call a method of a controller in another controller. I am able to get the instance of the controller but when I am calling it method it returns me this error TypeError: Object [object Object] has no method.
This is how I am calling it:
Cards.CardsIndexController = Ember.Controller.extend({
needs: 'account_info',
actions: {
accountInfoStart:function(){
console.log(this.get('controllers.account_info').test()); // error here
}
}
});
This is the controller whose function I want to call
Cards.AccountInfoController = Ember.Controller.extend({
actions:{
test: function(){
alert(1);
}
}
});
How can I solve it?
test is not technically a method, but an action or event. Use the send method instead:
this.get('controllers.account_info').send('test', arg1, arg2);
As per Ember documentation; create a property that lazily looks up another controller in the container. This can only be used when defining another controller.
legacy ember application example:
App.PostController = Ember.Controller.extend({
accountInfo: Ember.inject.controller()
this.get('accountInfo').send('test')
});
modern ember application example:
// in an ember app created with ember-cli
// below snippet would be the app/controllers/post.js file
import Ember from 'ember';
export default Ember.Controller.extend({
appController: Ember.inject.controller('application')
});
You can find more documentation about Ember.inject here
From the Updated Ember Documentation :
import { inject } from '#ember/controller';
export default Ember.Controller.extend({
appController: inject('application')
});
