I've been hitting my head against a wall all day trying to figure out
why I can't get REST functionality working in my project, and I seem
to have hit the following problem:
REST worked great when I use symfony generated links with link_to, or
using symfony generated forms. But I cannot for the life of me get
REST to work using xhr methods.
I'm currently using Dojo 1.4.1, and I'm trying to delete an entity
using REST. However, whenever I submit the request to the server using
xhrPost or xhrDelete, the symfony routing sends me to the "show"
action and not the "delete" action.
I would greatly appreciate it if someone could take a look at the
information below and let me know what I'm doing wrong…
Here's the routing:
email_usage_show:
url: /email/usage/:id.:sf_format
param:
module: addressUsage
action: showEmailAddressUsage
requirements:
sf_method: get
id: \d+
email_usage_delete:
url: /email/usage/:id.:sf_format
class: sfDoctrineRoute
options:
model: AddressUsage
type: object
param:
module: addressUsage
action: deleteEmailAddressUsage
sf_format: json
requirements:
sf_method: delete
id: \d+
Here's the symfony link that *does* work:
<a href="/frontend_dev.php/email/usage/4
onclick="if (confirm('Are you sure?')) {
var f = document.createElement('form');
f.style.display = 'none';
this.parentNode.appendChild(f);
f.method = 'post';
f.action = this.href;
f.target = 'newPage';
var m = document.createElement('input');
m.setAttribute('type', 'hidden');
m.setAttribute('name', 'sf_method');
m.setAttribute('value', 'delete');
f.appendChild(m);f.submit();
};
return false;">!!DELETE!!</a>
Here's the dojo xhrPost that *doesn't* work:
dojo.xhrDelete ({
url: '/frontend_dev.php/email/usage/4',
handleAs: 'json',
content: {sf_format: 'delete'},
load: dojo.hitch(this, this.onDeleteSuccess),
error: dojo.hitch(this, this.onDeleteFailure)
});
Here's the FireBug output from the symphony link:
