I have a controller responsible for communicating with an API to update properties of a user, name, email, etc. Each user has an 'id'
which is passed from the server when the profile page is viewed.
I would like to pass this value to the AngularJS controller so it knows what the API entry point is for the current user. I've tried passing the value in ng-controller
. For example:
function UserCtrl(id, $scope, $filter) {
$scope.connection = $resource('api.com/user/' + id)
and in the HTML
<body ng-controller="UserCtrl({% id %})">
where {% id %}
print the id sent from the server. but I get errors.
What is the correct way to pass a value into a controller on its creation?

Original Answer:
I answered this to Yes you absolutely can do so using ng-init
and a simple init function.
Here is the example of it on plunker
HTML
<!DOCTYPE html>
<html ng-app="angularjs-starter">
<head lang="en">
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.0.3/angular.min.js"></script>
<script src="app.js"></script>
</head>
<body ng-controller="MainCtrl" ng-init="init('James Bond','007')">
<h1>I am {{name}} {{id}}</h1>
</body>
</html>
JavaScript
var app = angular.module('angularjs-starter', []);
app.controller('MainCtrl', function($scope) {
$scope.init = function(name, id)
{
//This function is sort of private constructor for controller
$scope.id = id;
$scope.name = name;
//Based on passed argument you can make a call to resource
//and initialize more objects
//$resource.getMeBond(007)
};
});
