POST a JSON array with ANGULARJS $resource - angularjs

Question

I need to do send a json array to a restful api from my angularjs application. I am using ngresources to do this.
Since now, I have been abled to post and put single object with no problem, but now I need to send an array of objects and I can't.
I tried to do the call from a external rest application and it works fine but it's impossible from my angular application. I have trie to parse the objet with JSON.stringify but stills not working. I set the header 'Content-Type': 'application/json', as well on the $resources.
This is how I do the negresource:
.factory('AddSignosClinicos', function ($resource) {
return $resource(dondeapuntar + "/Rest/Pacientedatossignosclinicos.svc/pACIENTEDATOSSIGNOSCLINICOSList/Add", {}, {
create: { method: "POST", headers: { 'Content-Type': 'application/json', params: {} } }
});
})
And this is how I call the function:
var objeto = JSON.stringify(SignosClinicosGuardar);
var signosClinicosService = new AddSignosClinicos(objeto);
signosClinicosService.$create().then(function () {});
I made a console.log of objeto, and is a proper json array.
Any idea?
Thank you very much
EDIT
I have tried $http component for the post request, and it worked! I don´t understand why is not working with ngResources, this is my code for $http:
$http({
url: 'http://localhost:1046/Rest/Pacientedatossignosclinicos.svc/pACIENTEDATOSSIGNOSCLINICOSList/Add',
method: "POST",
data: SignosClinicosGuardar,
headers: {
'Content-Type': 'application/json; charset=UTF-8'
}
});

To post an array of objects you'll need to add the option isArray: true to your $resource:
.factory('AddSignosClinicos', function ($resource) {
return $resource(
"url-string-here",
{},
{
create: {
method: "POST",
isArray: true
}
}
);
})
Calling the new create function would look something like this:
//some list of your object instances
var array_of_objects = ...
var saved_objects = AddSignosClinicos.create(
array_of_objects
);
saved_objects.$promise.then(function() {
...
});
Note, the create vs $create, there's no $.
See the Angular documentation on $resource
