Router and refresh multiples ng-inludes

I start with code:

when('/admin', {
    templateUrl: 'partials/admin/layout.html',
    controller: AdminCtrl
})
when('/admin/products', {
    templateUrl: '????',
    controller: AdminProductsCtrl
})

Template "tree":

index.html ---> <div ng-view/>
---layout.html ---> <div ng-include=menu/> and <div ng-include=body/>
------menu.html 
------products.html 

Actually I do this:

function AdminCtrl($scope) {
     $scope.menu = 'partials/admin/menu.html';
}

function AdminProductsCtrl($scope) {
    $scope.menu = 'partials/admin/menu.html';
    $scope.body = 'partials/admin/products/index.html';
}

The point is: What I put in '????', if I put layout.html this work fine, but I like just "refresh" ng-include=body. I think that my concepts about Angularjs is wrong.

Other problem is, when AdminProductsCtrl "take the control" of layout.html I miss the AdminCtrl $scope, this implicates repeat all AdminCtrl $scope in AdminProductsCtrl $scope (for example $scope.menu).

Thanks a lot, and sorry for "my english".

UPDATE

After think.. and think... I understanding that routes not apply for my app, then I manage all functionality under one url 'site.com/#/admin'. The menu.html is manage for AdminMenuCtrl, this controller contains a model for each 'ng-include' and contains one method for each menu entry. When the user click a menu entry, the associate method in the $scope replace $scope.includes.body with the 'new' html. The partial cointains your ng-controller.

This works fine by now :D. And the best is that I don't need use $rootScope.

The new problem is a bit more complicated, the ng-include require a tag (i.e DIV) and ng-controller too. Then my design is affected for this. In code language:

DESING:

<div>MENU-HTML</div>
<div>BODY-HTML</div>

TEMPLATE:

<div ng-include="menu"></div>
<div ng-include="body"></div>

AFTER RETRIEVE PARTIALS:

<div ng-include="menu"><div ng-controller="MenuCtrl">MENU-HTML</div></div>
<div ng-include="body"><div ng-controller="ListProductsCtrl">BODY-HTML</div></div>

THE IDEAL THING:

1 - ng-include don't 'include' into the DIV, instead 'replace' the DIV.

2 - ng-controller DIV is replaced for nothing in the DOM.

It's possible now with angular? Is a bad approach this idea? The point 2 with $route is possible, not with ng-controller directive.

I believe you are correct in your example you would set ???? to layout.html but the idea is to have different views based on the route so pointing to the same layout.html is not ideal.

If you are trying to keep a static menu on all pages I would add the menu to your index.html and then choose a different templateUrl for each route (ie /admin goes to partials/admin.html and /admin/products goes to partials/products.html) and not use the ngInclude.

I'm new to AngularJS but I'm getting the impression that you generally want to use ngView with routes to templateUrls OR use ngInclude (possibly with ngSwitch) if you want to roll your own view switching. I'm sure there are times when using both is appropriate but as a newbie it confuses me somewhat. Resident experts please correct me if I'm wrong!

For your second issue there might be some helpful information here and here for tips on sharing the same model across multiple controllers but you probably don't need to for your example.

An alternative is to use a string constant path to your partial in layout.html and remove the references to $scope.menu in your controller code by using:

<div ng-include="'partials/admin/menu.html'"/>
