javascript - Partial views in AngularJS

Question

I'm new to Angular and would appreciate any advice. Basically, I have one-to-many relationship- one Category has several Product, I have the layout page where I render different partial views:

<div class="mainContent">
     <ng-view></ng-view>
</div>

My first view shows the list of categories, when one of them is clicked, I show the second view, which is separated to two parts: list of categories, and list of products of particular category, schematically it looks like:

My problem is that I cannot figure out how to use another partial for the list of products because want to keep them in separate .html.

I configured routes:

app.config(function($routeProvider, $locationProvider) {
$routeProvider
    .when('/category', {
        templateUrl: 'category.html',
        controller: 'categoryController as catCtrl'
    })
    .when('/category/:id', {
        templateUrl: 'categoryDetail.html',
        controller: 'categoryDetailController as catDetailCtrl'
    })       
    .when('/product/:category_id', {
        templateUrl: 'product.html',
        controller: 'productController as productCtrl'
    })
    .otherwise({
        redirectTo: "/category"
    });
});

And controllers:

app.controller("categoryController", function($http)
{
    var vm = this;
    vm.categories = somedata;
});
app.controller("categoryDetailController", function($http, $routeParams)
{
   var vm = this;
   vm.category = somedata;//current category from REST api, using $routeParams.id
});
app.controller("productController", function($http, $routeParams)
{
   var vm = this;
   vm.products = somedata;//product list of current category using $routeParams.category_id
});

So on my first view - category.html, I have the list of categories with hrefs:

<a href="#/category/{{category.id}}">

On the second - categoryDetail.html, I list categories again but with another hrefs:

<a href="#/product/{{category.id}}">

And on the last view - product.html I list the products.

Till now, when I click on category inside categoryDetail.html my product.html renders in mainContent div of the layout, instead - I need it to render as inner partial inside categoryDetail.html. I tried to use <ng-view> again, but this does not seem to be correct.

there are couple ways for partials in AngularJS.

ng-include

If theres no logic, or it will be provided from parent scope you can just include a html file into your view.

Example:

<div ng-include="'/path/to/your/file.html'"></div>

new directive

If you'll have a bit logic in your partial, and you'd like to use it as a separate module in your app - I'll strongly advice to built a new directive.

Example.

PS. If you're new to Angular, this may be useful :-)
