Getting proper data model when rendering into outlet in Ember - javascript

I am trying to create a select box in a modal that has a list of all cars in inventory. If I enter the app from a page that has all the data loaded and open the modal it works correctly. However if I am on a route that doesn't have the data loaded, then open the modal the select options do not show. Furthermore the options will never update from that point. How do I get the proper data to load? Should not this work since I am fetching the data direct from the store?
Dms.SellDialogController = Ember.ArrayController.extend({
cars: function() {
return this.store.find('car').filterProperty('isSold', false);
}.property('model'),
selectedCar: '',
carObjects: function() {
var cars = this.get('cars').map(function(car) {
return obj = {id: car.get('id'), key: car.get('keyNumber'), label: 'KEY#:'+car.get('keyNumber') + ' - STOCK#:' + car.get('stock')+' '+car.get('year')+' '+car.get('vModel')};
});
cars.sort(function(a, b){return a.key-b.key;})
return cars;
}.property('route'),
title: 'Select the car you are selling'
});
ApplicationRoute...
...
openModal: function(modalName, model) {
this.render(modalName, {
into: 'application',
outlet: 'modal',
model: model
});
},
Action to open modal inside application template
{{action 'openModal' 'sellDialog' model}}
and the templates
<script type="text/x-handlebars" id="components/modal-dialog">
<div class='modal-overlay' {{action "closeModal" target=cntrllr}}>
<div class='modal' {{action "dngn" target=cntrllr bubbles=false}}>
<div class='modal-content'>
<div class='modal-header'>
<button type="button" class="close" aria-label="Close" {{action "closeModal" target=cntrllr}}><span aria-hidden="true">×</span></button>
<h4 class="modal-title">{{title}}</h4>
</div>
{{yield}}
</div>
</div>
</div>
</script>
<script type="text/x-handlebars" data-template-name="sellDialog">
{{#modal-dialog title=title cntrllr=controller model=model}}
<div class="modal-body">
<span class='pull-left'>Key Number:
{{view "select" content=carObjects optionValuePath="content.id" optionLabelPath="content.label" selection=selectedCar}}
</span>
</div>
<div class="modal-footer">
<button {{action "modalAction" controller "sell" selectedCar.id}}>Sell</button>
<button {{action "closeModal"}}>Cancel</button>
</div>
{{/modal-dialog}}
</script>
UPDATE 2015/5/4:
I have a hack to make it work for now. I added a cars property in the application route and I am getting it in SellDialogController. This looks like a bug to me. I will make a jsFiddle when I get some time and check it further before issuing a bug report.

try using setupController on the Application Route, since setupController is always called.
import Ember from 'ember';
export default Ember.Route.extend({
model: Ember.RSVP.hash({
optionsForSelect: function() {
// fetch your select data here
},
otherData: function() {
// get your regular model data here
}
}),
setupController: function(controller, model) {
this.controllerFor('sellDialog').set('model', model.optionsForSelect);
this.controller.set('model', model.otherData);
}
});

Form modal binding in laravel with vue js

I have 2 models Tour.php
public function Itinerary()
{
return $this->hasMany('App\Itinerary', 'tour_id');
}
and Itinerary.php
public function tour()
{
return $this->belongsTo('App\Tour', 'tour_id');
}
tours table:
id|title|content
itineraries table:
id|tour_id|day|itinerary
In tour-edit.blade.php view I have used vue js to create or add and remove input field for day and plan dynamically.
Code in tour-create.blade.php
<div class="row input-margin" id="repeat">
<div class="col-md-12">
<div class="row" v-for="row in rows">
<div class="row">
<div class="col-md-2">
<label >Day:</label>
<input type="text" name="day[]"
class="form-control">
</div>
<div class="col-md-8">
{{ Form::label('itinerary', " Tour itinerary:", ['class' => 'form-label-margin'])}}
{{ Form::textarea('itinerary[]',null, ['class' => 'form-control','id' => 'itinerary']) }}
</div>
<div class="col-md-2">
<button class="btn btn-danger" #click.prevent="deleteOption(row)">
<i class="fa fa-trash"></i></button>
</div>
</div>
</div>
<div class="row">
<button class="btn btn-primary add" #click.prevent="addNewOption" >
<i class="fa fa-plus"></i> Add Field</button>
</div>
</div>
</div>
I want to populate these fields with their respective data. But all data i.e itinerary belonging to a tour are being displayed in itinerary textbox in JSON format.
My vue js sript is:
<script>
var App = new Vue({
el: '#repeat',
data: {
day:1 ,
rows:[
#foreach ($tour->itinerary as $element)
{day: '{{$element->day}}', plan: '{{$element->plan}}'},
#endforeach
]
},
methods: {
addNewOption: function() {
var self = this;
self.rows.push({"day": "","itinerary":""});
},
deleteOption: function(row) {
var self = this;
self.rows.splice(row,1);
},
}
});
</script>
I would avoid mixing blade into JavaScript, instead the best option is to make an ajax call to an api route which returns your data in json, which can then be processed by Vue:
methods:{
getItinerary(){
axios.get('api/itinerary').then(response => {
this.itinerary = response.data;
})
}
}
However, with this approach you will likely need to use vue-router rather than laravel web routes, which puts us into SPA territory.
If that's not an option (i.e. you still want to use blade templates), you should take a look at this answer I gave the other day which shows you how to init data from your blade templates.
What you seem to be doing is using laravel's form model binding to populate your forms, not Vue, so your model data is not bound to the view. So, you will need to decide which one you want to use. If it's vue you just want to use a normal form and bind the underlying data to it using v-model:
Now any updates in the view will automatically be updated by Vue. I've put together a JSFiddle that assumes you will want to continue using Laravel web routes and blade templates to show you one approach to this problem: https://jsfiddle.net/w6qhLtnh/

Calling code after {{#each}} has rendered in ember.js?

I am trying to call some code after an Ember {{#each}} tag has finished looping through its items. I have seen other questions that looked similar and the answer always implemented didInsertElement on the view. This does not seem to work for me as I am trying to access html objects that are not rendered with the view because they are in the {{#each}}.
Here is what my html looks like.
<script type="text/x-handlebars" id="user">
{{#if isEditing}}
<div class="well">
{{partial 'user/edit'}}
<button {{action 'doneEditing'}} class="btn btn-default">Save</button>
<button {{action 'cancelEditing'}} class="btn btn-default">Cancel</button>
</div>
{{else}}
<button {{action 'edit'}} class="btn btn-default">Edit</button>
{{/if}}
</script>
<script type="text/x-handlebars" id="user/edit">
{{#view 'editor'}}
<div id="sList" class="btn-group-vertical" role="group">
{{#each s in model}}
<button class="btn btn-default">
{{s.theme}}
</button>
{{/each}}
</div>
{{/view}}
</script>
And my javascript
App.UserRoute = Ember.Route.extend({
model: function(params) {
return this.store.all('strength')
}
});
App.UserController = Ember.ObjectController.extend({
isEditing: false,
actions: {
edit: function(){
this.set("isEditing", true);
},
doneEditing: function(){
this.set("isEditing", false);
},
cancelEditing: function(){
this.set("isEditing", false);
}
}
});
App.EditorView = Ember.View.extend({
didInsertElement: function() {
//Do something to the button elements
}
});
When I try to run this, as soon as I hit the edit button and the partial loads, I get an error in the console after didInsertElement tried to access the button elements. It as if the elements in the div have not rendered yet. So how can I tell if the {{#each}} is done inserting elements into the html? I know this may be confusing but any and all help is appreciated.
Schedule your code in the afterRender queue to run after the contents of the view has been rendered.
App.EditorView = Ember.View.extend({
didInsertElement: function() {
Ember.run.schedule('afterRender', function() {
this.$().find('button').each(function() {
// $(this) is a button in this function
});
}.bind(this));
}
});

EmberJS passing variable to the layout

I have a really basic test app. It has 2 pages an empty index and a login form on an other page. And I would like to know how can I pass variables to the layout which is the same on every page (user name/status for display it and display login/logout by status).
Or the best solution could be something like this: pass a user model to the AppController which is available from anywhere (like login page or login modals) and If I change and save the data the site template is just changing by the passed variables.
I was trying to find a good way, I find a few ones but none of them was working :( If you know a working way please share me or show me what is the solution.
Here is my code: the JS I have:
App = Ember.Application.create();
App.ApplicationController = Ember.Controller.extend({});
/* *** Index *** */
App.IndexView = Ember.View.extend({
layoutName: 'app_view'
});
App.IndexController = Ember.Controller.extend({
});
/* *** LOGIN *** */
App.Router.map(function () {
this.resource("login");
});
App.LoginView = Ember.View.extend({
layoutName: 'app_view'
});
App.LoginController = Ember.Controller.extend({
login: function() {
// blah blah
}
});
Layout template:
<script type="text/x-handlebars" data-template-name="app_view">
<header id="site">
{{#link-to "index"}}Index{{/link-to}}
{{#link-to "login"}}Login{{/link-to}}
{{variablaWhatIWant}}
</header>
<hr />
<section id="content">
{{yield}}
</section>
<hr />
<footer id="main">
Footer
</footer>
</script>
2 view templates:
<script type="text/x-handlebars" data-template-name="index">
Hello INDEX page!
</script>
<script type="text/x-handlebars" data-template-name="login">
<form class="form-horizontal" {{action "login" on="submit"}}>
<div class="control-group">
Username: {{input value=username type="text"}}
</div>
<div class="control-group">
Password {{input value=password type="password"}}
</div>
<button type="submit" class="btn">Log in!</button>
</form>
</script>
Thank you very much! :)
You have the right idea, see managing dependancies between controllers http://emberjs.com/guides/controllers/dependencies-between-controllers
just set the needs property, and you can access that controller from any other
App.LoginController = Ember.Controller.extend({
needs: ['application'],
login: function() {
this.authenticate(this.get('username'), this.get('password')).then(function(user) {
this.set('controllers.application.user', user);
},
function(err) {
//auth err
}
}
});

Object disappearing from the view on save in Ember.js

Essentially I have a list of objects, and the user is able to add new ones by typing into a textbox. As the user types, the new object appears. However, when the user clicks save, the object disappears from the listing. It is successfully saved to the database (Ruby on Rails/SQLite) so it appears on a full refresh. Why is it doing this, and how can I get it to stay on the screen when the user presses submit?
Here is some relevant code:
index.hbs
<div class="messages">
{{#each userhashtag in controller}}
{{render "userhashtag" userhashtag}}
{{/each}}
{{#link-to 'userhashtags.new'}} Add Hashtag{{/link-to}}
</div>
{{outlet}}
show.hbs
{{userhashtag.name}} <button class="btn btn-dancer" type="submit" {{action "destroy"}}>Remove</button><br>
new.hbs
<form role="form">
<fieldset>
<div class="form-group">
{{view Ember.TextField valueBinding='name' class='form-control' name='name' viewName='nameField'}}
</div>
<div class="btn-group">
<button type="submit" {{action "save"}} class="btn btn-success">Submit</button>
</div>
route
App.UserhashtagsNewRoute = Ember.Route.extend({
model: function(){
return this.store.createRecord('userhashtag');
},
setupController: function(controller, model){
controller.set('model', model);
},
renderTemplate: function() {
this.render('app/templates/userhashtags/new');
},
actions: {
save: function(){
return this.controller.get('model').save().then(function(){
this.transitionTo('userhashtags');
}.bind(this));
}
}
});
Make sure that you are manually pushing the new model into your Array collection (not sure how you're managing the collection). I'd suggest moving the #save action into a controller where you manage the list of objects.
// assuming "list" is some reference to your collection list within your controller
save: function() {
this.get('userhashtag').save().then(function(_model){
list.pushObject(_model);

Bootstrap 3 Modal with Ember.js, no data in modal

I want to use Bootstrap 3's modal along with Ember.js. So far, I have been unsucessfull. The data modal itself is not appearing, although the screen is doing the fade.
my app.js:
App = Ember.Application.create();
App.ApplicationRoute = Ember.Route.extend({
events: {
showGroups: function() {
this.container.lookup('view:groups').append();
}
}
});
App.GroupsRoute = Ember.Route.extend({
model: function() {
return groups;
}
});
App.GroupsView = Ember.View.extend({
templateName: "groups",
classNames: ["modal", "fade"],
didInsertElement: function() {
this.$().modal('show');
this.$().one("hidden", this._viewDidHide);
},
// modal dismissed by example clicked in X, make sure the modal view is destroyed
_viewDidHide: function() {
if (!this.isDestroyed) {
this.destroy();
}
},
// here we click in close button so _viewDidHide is called
close: function() {
this.$(".close").click();
}
});
var groups = [
{
id: 1,
name: 'Family Reunion',
},
{
id: 2,
name: 'California Trip',
},
{
id: 3,
name: 'Dream Vacations',
},
{
id: 4,
name: 'Fun for Kids',
},
];
My templates:
<script type="text/x-handlebars" data-template-name="application">
<button class="btn actionBtn userControls" {{action showGroups}}><span class="glyphicon glyphicon-heart"></span> &nbsp My Favorites</button>
<!-- Split button -->
<div class="btn-group">
<button type="button" class="btn secondaryBtn userControls"><span class="glyphicon glyphicon-user"></span> &nbsp Hello, <b>User</b></button>
<button type="button" class="btn secondaryBtn dropdown-toggle userControls" data-toggle="dropdown">
<span class="caret"></span>
</button>
<ul class="dropdown-menu secondaryMenu" role="menu">
<li>Account Settings</li>
<li>Logout</li>
</ul>
</div>
</script>
<script type="text/x-handlebars" data-template-name="groups">>
<div class="modal fade" id="favoritesModal">
<div class="modal-dialog">

<h4 class="modal-title tertiaryHeading">My Favorite Groups</h4>
</div>
<div class="modal-body">
{{#each model}}
{{render "group" this}}
{{/each}}
</div>
<div class="modal-footer">
<button type="button" class="btn actionBtn">Create New Group</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
</script>
<script type="text/x-handlebars" data-template-name="group">
<button class="btn secondaryBtn groupBtn">{{name}}</button>
</script>
How can I make this work? I'm new to Ember, and not sure if I understand how to inject data into a view?
You have two issues that are slowing you down.
First, your 'groups' template is never being inserted into the DOM. this.container.lookup('view:groups').append() does not do what you seem to think it does. The Ember Way (tm) is to use an outlet for rendering nested templates, and modals are really just a special case of nesting. (You can use the View Tree of the Ember inspector to see that the 'groups' template is never inserted.)
I would recommend altering your ApplicationRoute to be this (use actions instead of events, and just transitionTo the 'groups' route):
App.ApplicationRoute = Ember.Route.extend({
actions: {
showGroups: function() {
this.transitionTo('groups');
}
}
});
At this point you should see that the 'groups' template is making it into the DOM, but it's still not being shown. This is due to the second issue, which is that you have a modal inside a modal (yo dawg!). Your GroupsView is creating a new element and setting class names of modal and fade on the new element. Your groups template is being rendered into that element, but the outer div in your groups template has the class names of modal and fade. The outer modal (created by GroupsView) is being "displayed", but since it contains content that is explicitly hidden (due to the modal fade classes) nothing is shown on screen. You could either remove the outer div in your template, or remove the class names from GroupsView, and then display the modal with this.$('#favoritesModal').modal('show').
