How to update hasMany in Ember.js using different controllers?
Hi
I have Ruby on Rails 4.0.3
app and I am using Ember.js
DEBUG: Ember : 1.6.0-beta.3 ember.js?body=1:3917
DEBUG: Ember Data : 1.0.0-beta.7+canary.f482da04 ember.js?body=1:3917
DEBUG: Handlebars : 1.3.0 ember.js?body=1:3917
DEBUG: jQuery : 1.11.0
I want to display hasMany
in the same view using different controllers.
I have seen some example on StackOverflow but most (if not all) of them are for displaying records.
Ok talk is cheap, I am showing the code:
Models:
-javascripts/models/task.js
EmTasks.Task = DS.Model.extend({
name: DS.attr('string'),
description: DS.attr("string"),
list: DS.belongsTo('list')
});
-javascripts/models/list.js
EmTasks.List = DS.Model.extend({
name: DS.attr('string'),
tasks: DS.hasMany('task')
});
Router:
-javascripts/router.js
EmTasks.Router.map(function(){
return this.route("lists", {
path: '/'
});
});
EmTasks.ListsRoute = Ember.Route.extend({
model: function() {
return this.store.find('list');
}
});
Controllers:
-javascripts/controllers/lists_controller.js
EmTasks.ListsController = Em.ArrayController.extend({
addList: function() {
this.store.createRecord('list', {
name: this.get('newListName')
}).save();
return this.set('newListName', '');
},
destroyList: function(id) {
if (confirm("Are you sure?")) {
this.get('store').find('list', id).then( function(record) {
record.destroyRecord();
});
}
},
});
-javascripts/controllers/list_controller.js
EmTasks.ListController = Em.ObjectController.extend({
actions: {
editList: function() {
this.set('isEditingList', true);
var model = this.get('model')
},
acceptChanges: function () {
this.set('isEditingList', false);
var name = this.get('model.name');
if (Ember.isEmpty(name)) {
this.send('removeList');
} else {
var list = this.get('model')
list.set('name', name);
list.save()
}
},
removeList: function () {
var list = this.get('model');
list.destroyRecord();
}
},
isEditingList: false
});
-javascripts/controllers/task_controller.js
EmTasks.TaskController = Em.ObjectController.extend({
isEditingTask: false
});
Templates:
-javascripts/templates/lists.handlebars [fragment]
{{#each itemController='list'}}
<div class='col-md-8'>
<h3>
{{#if isEditingList}}
{{edit-input class="form-control" value=name focus-out="acceptChanges" insert-newline="acceptChanges"}}
{{else}}
<div {{action 'editList' on='doubleClick'}}>
{{name}}
</div>
{{/if}}
</h3>
</div>
<div class='col-md-4 down13p'>
<button class="btn btn-danger btn-small pull-right" {{action "destroyList" id}} type="button">
<span class="glyphicon glyphicon-ban-circle"></span>
</button>
</div>
{{#each task in this.tasks }}
<div class="col-md-10">
{{#if task.isEditingTask}}
{{edit-input class="form-control" value=task.name focus-out="acceptChanges" insert-newline="acceptChanges"}}
{{else}}
<div {{action 'editList' on='doubleClick'}}>
{{name}}
</div>
{{/if}}
But is looks like isEditingTask
property is not working...
Any idea how to fix that?
OK found a solution, just add itemController
to tasks each
loop
{{#each task in this.tasks itemController='task' }}
<div class="col-md-10">
{{#if task.isEditingTask}}
{{edit-input class="form-control" value=task.name focus-out="acceptChanges" insert-newline="acceptChanges"}}
{{else}}
<div {{action 'editTask' on='doubleClick'}}>
{{name}}
</div>
{{/if}}
