Angular - Select array in json object

Question

I have a json object of arrays that looks like this:

[
    {
        "id": 1,
        "name": "John Smith",
        "age": 52
    },
    {
        "id": 2,
        "name": "Jane Walters",
        "age": 43
    },
    {
        "id": 3,
        "name": "Mike Wilson",
        "age": 65
    },
    {
        "id": 4,
        "name": "Tom Samuels",
        "age": 29
    }
]

I am displaying all these names on the "index" page, and I want to show only one on each of the "character/[id]" pages. Here is my controller for the index page:

angular.module('myApp.controllers', []).
    controller('index', ['$scope', 'characters', function($scope, c){
        $scope.characters = c.getCharacters;
    }]);

Aaand here's the "characters" service:

factory('characters', function($resource){
    return $resource('JSON/characters.json', {}, 
    {
        'getCharacters':    {method: 'GET', isArray:true}
    }); 
});

The views are the standard boilerplate.

My problem is, how do I create a service (or manipulate the object in the controller) for the "character/[id]" route so it only selects a single array based on the JSON id?

I did the phonecat demo on angularjs.org, but that demo uses separate JSON files for each phone, and then one big JSON file for the index page. I want to avoid that.

One final thing: I am using angular-seed, so I'd like to maintain the syntax used there. I've tried lots of different approaches with no luck.

Example in my own proyect:

The controller:

app.controller("prodDetalleController", ["$scope","$http","$routeParams", function($scope,$http,$routeParams ){    

  vm = this;
  $scope.id = $routeParams.idProducto;


    // Listado de productos
    $http.get("_producto.php?id="+$scope.id)
    .success(function (respuesta) 
    {
        vm.producto = respuesta;}
    )
    .error(function(){
        vm.producto = "Error: no hay datos.";
    }); 

}]); // fin ctrl

And in PHP:

<?php

 $id = $_GET['id'];
 //echo $id;

$conn = @new mysqli('localhost', 'root','buenosaires','martin_db');

$result = $conn->query("SELECT * FROM productos WHERE idProducto=$id");

$myArray = array();

...

And in view:

{{producto.titulo}}
{{producto.descripcion}}

...

Basically, you are asking how you can get id from the route url.

define your character route path like:

/character/:id

and in your character controller like

....controller('characterCtrl', ['$scope', 'characters','$routeParams' function($scope, c,$params){
    $scope.characters = c.getCharacters;
    //you have $params.id here as the id from the url
}]);

on the commented line loop through the $scope.characters to find the one with matching id and set that to another scope variable. A jsFiddle with your current pages/view and controllers could be more useful while helping.
