The updated example below works with ember.js RC1 -- 03/14/2013
First you need to add a pagination like mixin as one doesn't yet exist in the ember core
var get = Ember.get, set = Ember.set;
Ember.PaginationMixin = Ember.Mixin.create({
pages: function() {
var availablePages = this.get('availablePages'),
pages = [],
page;
for (i = 0; i < availablePages; i++) {
page = i + 1;
pages.push({ page_id: page.toString() });
}
return pages;
}.property('availablePages'),
currentPage: function() {
return parseInt(this.get('selectedPage'), 10) || 1;
}.property('selectedPage'),
nextPage: function() {
var nextPage = this.get('currentPage') + 1;
var availablePages = this.get('availablePages');
if (nextPage <= availablePages) {
return Ember.Object.create({id: nextPage});
}else{
return Ember.Object.create({id: this.get('currentPage')});
}
}.property('currentPage', 'availablePages'),
prevPage: function() {
var prevPage = this.get('currentPage') - 1;
if (prevPage > 0) {
return Ember.Object.create({id: prevPage});
}else{
return Ember.Object.create({id: this.get('currentPage')});
}
}.property('currentPage'),
availablePages: function() {
return Math.ceil((this.get('content.length') / this.get('itemsPerPage')) || 1);
}.property('content.length'),
paginatedContent: function() {
var selectedPage = this.get('selectedPage') || 1;
var upperBound = (selectedPage * this.get('itemsPerPage'));
var lowerBound = (selectedPage * this.get('itemsPerPage')) - this.get('itemsPerPage');
var models = this.get('content');
return models.slice(lowerBound, upperBound);
}.property('selectedPage', 'content.@each')
});
Next you need to use the mixin above in your ArrayController like so
PersonApp.PersonController = Ember.ArrayController.extend(Ember.PaginationMixin, {
itemsPerPage: 2
});
Next you can add a simple helper view to display the page numbers as li tags
PersonApp.PaginationView = Ember.View.extend({
templateName: 'pagination',
tagName: 'li',
page: function() {
return Ember.Object.create({id: this.get('content.page_id')});
}.property()
});
Your routes might look something like this (nested page under the parent)
PersonApp.Router.map(function(match) {
this.resource("person", { path: "/" }, function() {
this.route("page", { path: "/page/:page_id" });
});
});
PersonApp.PersonPageRoute = Ember.Route.extend({
model: function(params) {
return Ember.Object.create({id: params.page_id});
},
setupController: function(controller, model) {
this.controllerFor('person').set('selectedPage', model.get('id'));
}
});
PersonApp.PersonRoute = Ember.Route.extend({
model: function(params) {
this.controllerFor('person').set('selectedPage', 1);
return PersonApp.Person.find();
}
});
And finally, you need to add some html to display it
<script type="text/x-handlebars" data-template-name="application">
<div id="main">
{{ outlet }}
</div>
</script>
<script type="text/x-handlebars" data-template-name="person">
<table width="250px">
<thead>
<th>id</th>
<th>username</th>
</thead>
<tbody>
{{#each person in controller.paginatedContent}}
<tr>
<td>{{person.id}}</td>
<td>{{view Ember.TextField valueBinding="person.username"}}</td>
</tr>
{{/each}}
</tbody>
</table>
<div name="prev">{{#linkTo 'person.page' prevPage target="controller"}}Prev{{/linkTo}}</div>
<ul class="pagination gui-text">
{{#each pages}}
{{view PersonApp.PaginationView contentBinding="this"}}
{{/each}}
</ul>
<div name="next">{{#linkTo 'person.page' nextPage target="controller"}}Next{{/linkTo}}</div>
</script>
<script type="text/x-handlebars" data-template-name="pagination">
{{#with view}}
{{#linkTo 'person.page' page}}
{{content.page_id}}
{{/linkTo}}
{{/with}}
</script>
