I am trying to do something that sounds simple but I can't find the solution.
My application needs to edit documents which contains pages.
Here is my model :
MyApplication.Document = DS.Model.extend({
title: DS.attr('string'),
pages: DS.hasMany('page', {async: true})
});
MyApplication.Page = DS.Model.extend({
document: DS.belongsTo('document', {async: true}),
title: DS.attr('string'),
params: DS.attr(),
objects: DS.attr()
});
And the routes :
MyApplication.Router.map(function () {
this.resource('document', {path: '/document/:document_id'});
});
MyApplication.Document = Ember.Route.extend({
model: function (params) {
return this.store.find('document', params.document_id);
}
});
When I load the document 1, the application call http://www.myserver.com/api/document/1
.
The problem is that when I want to find a page of the document, it calls
http://www.myserver.com/api/pages/ID
instead of
http://www.myserver.com/api/document/1/pages/ID
Theses nested URL are important in my application.
I found different things on the subject like adding links
in the JSON response :
{
"document": {
"id": "1",
"title": "Titre du document",
"pages": ["1", "2", "3"],
"links": {"pages" : "pages"}
},
But when I call for the pages, it requests http://www.myserver.com/api/document/1/pages
without the id.
I also try specify the document when I ask for the page :
this.store.find("page", 1, {document:1});
Can't find a complete documentation on this subject, so if someone can explain me what's wrong, I'll be happy.
Thank.
Depends : EMBER DATA >= V1.0.0-BETA.9
The way to handle nested routes is hidden under release notes
Need to send back the links with response like this
{ "document": { "id": 1, "title": "Titre du document", "links": {"pages" : "/documents/1/pages"} }
You'll need to customize the adapter:page
's buldUrl
method like
MyApplication.PageAdapter = DS.RestAdapter.extend({ // NOTE: this is just a simple example, but you might actually need more customization when necessary buildURL: function(type, id, snapshot) { return '/documents/' + snapshot.record.get('document.id') + '/pages/' + id; } });
@code-jaff answer adapted to Ember 2.1.0:
// app/adapters/page.js
import DS from './application'; // I suppose you have your adapter/application.js
export default DS.RESTAdapter.extend({
buildURL: function(type, id, snapshot) {
return this.host + '/' + this.namespace + '/documents/' + snapshot.record.get('document.id') + '/pages/' + id;
}
});
Your problem likely stems from the quotes that are surrounding the IDs in your JSON. If you modify your serializer so that there are no quotes for the the IDs both around the document ID and the pages IDs, you should get the behavior that you expect. Also, you need to modify the formatting of your links to point to the relative path:
The resulting JSON should look like:
{
"document": {
"id": 1,
"title": "Titre du document",
"pages": [1, 2, 3],
"links": {"pages" : "/documents/1/pages"}
}
Please see this answer for a description of why adherence to Ember's expectations with regard to the JSON format is important and for an overview of the expected format.
