My dash board is below

var controllerId = 'dashboard';
angular.module('app').controller(controllerId, ['common', 'datacontext', dashboard]);

function dashboard(common) {
    var getLogFn = common.logger.getLogFn;
    var log = getLogFn(controllerId);

    var vm = this;
    vm.news = {
        title: 'Hot Towel Angular',
        description: 'Hot Towel Angular is a SPA template for Angular developers.'
    };
    vm.messageCount = 0;
    vm.people = [];
    vm.title = 'Dashboard';

    //Call Active Init
    activate();

    function activate() {
        var promises = [getMessageCount(), getPeople()];
        common.activateController(promises, controllerId)
            .then(function () { log('Activated Dashboard View'); });
    }

    function getMessageCount() {
        return datacontext.getMessageCount().then(function (data) {
            return vm.messageCount = data;
        });

    }

    function getPeople() {
        return datacontext.getPeople().then(function (data) {
            return vm.people = data;
        });

    }
}

})();

Why is datacontext undefined?

Answer 1

You are not loading it in the dashboard definition

Here, you are defining a controller, and injecting two dependencies, common and datacontext, which is good:

angular.module('app').controller(controllerId, ['common', 'datacontext', dashboard]);

But here, you are defining the dashboard function (the last parameter in the controller definition) to only have one parameter:

function dashboard(common)

....so that datacontext that you are injecting is actually being ignored. You should change the dashboard definition to this:

function dashboard(common, datacontext) {
   ...
}
