Navigate to a third-level nested view in Angular-UI-Router without prior knowledge of the second-level nested view

I currently have a few "parent modules", such as:

  • user
  • community

In addition, I have "embeddable modules", including:

  • photos
  • videos
  • wiki

These embeddable modules can be embedded into the parent modules. Each module does not have cross dependencies. For example, a user may not know that they have photos, videos, and a wiki, but are aware of a list of embeddable modules that will be included on their page. Similarly, the photos, videos, and wiki modules do not know where they will be embedded.

There are 3 layers of views: - base view layer (includes top navigation bar, logo, etc.) - focuses on the parent view being injected - parent object view layer (e.g., user or community, which displays user photo and name) - focuses on its embeddable views being injected - embeddable view layer - manages what is inside its specific view

Now let's consider the scenario where I am on the user page. The route for the user is #/user. If I want to access the photos of the user through a link, for instance

<a href="#/user/photos/">user photos</a>
, I encounter an issue because the route name in the photos module is #/photos, making #/user/photos/ ineffective.

If I simply access

<a href="#/photos">user photos</a>
, it would remove the parent view (the parent object view layer), resulting in the removal of the user photo and name from the screen.

Do you have any suggestions on how to access the photos module while retaining the parent view without creating hard-coded dependencies?

I require something similar to this solution:

$stateProvider
   .state(':parent/photos', {
            url: ':parent/photos',
            templateUrl: 'modules/photos/index.html',
            controller: 'PhotosCtrl'
       })

This setup would allow me to access the photos module from the user page like so:

<a href="#/user/photos">user photos</a>
or from the community page like:
<a href="#/community/photos">community photos</a>

The photos module could then utilize the :parent parameter to determine its parent context.

Alternatively, having linking functionality such as:

$stateProvider.state('user.photos', /*&*/'photos')

to connect modules at a global level would also be beneficial.

Your concept of using a GalleryStateFactory is solid. However, my suggestion would be to incorporate it as a provider instead. By doing so, you can make it dependent on the $stateProvider and implement it like this:

mod.provider('$galleryState', ['$stateProvider', function(sp) {

  this.galleryStates = function(parent) {
    sp.state(parent+'.gallery', GalleryStateFactory.default)
      .state(parent+'.gallery.photos', GalleryStateFactory.photos)
      .state(parent+'.gallery.albums',GalleryStateFactory.albums);
  }


  this.$get = angular.noop; //unless you want some additional service...
}]

$galleryStateProvider
    .galleryStates('user')
    .galleryStates('community');
