can't use the uid in my URL for SEO

[heshamelmasry77]

Hey thank you for sharing this repo it is very helpful.
I am facing a big huge problem to get my URLS to be seo friendly.

at the controller here we are using the id to get the document but i don't want to use it.

I want to use the uid for example it doesn't work.

that what we have :
$routeProvider.when('/document/:id/:slug', {templateUrl: 'partials/document.html', controller: 'DocumentCtrl'});

i wanna use this :
$routeProvider.when('/document/:uid/:slug', {templateUrl: 'partials/document.html', controller: 'DocumentCtrl'});

and when i redirect i wanna use this :

<a ng-href="#/document/{{document.uid}}/{{document.slug}}">
           {{document.slug}}
       </a>

i want my link to be something like this :
http://127.0.0.1:52486/app/index.html#/document/make/tata
make is a type in my prismic repo i made it whatever i want anything else from the fragment object not the id
i tried many things but it nothing worked with me.
