Guide to connecting to various controllers in Angular

To streamline the process of fetching data from the server and paginating it for all resources, I developed a custom ListCtrl. However, before setting it up, this controller needs to receive certain configurations such as the path to the resource and default limit.

My initial idea was to incorporate the ListCtrl within a larger controller and pass necessary parameters like this:

<div ng-controller="DashboardCtrl as dashboard">
 <div ng-controller="ListCtrl as list" ng-init="list.init(dashboard.listParams)">
  <... Iterate through list.items ...>
 </div>
</div>

After some research, I came across articles suggesting that using ng-init is not ideal and should only be utilized for list initialization purposes. Is there a more efficient approach that does not involve ng-init? Or is this current method acceptable?

It is recommended to utilize a directive instead of simply attaching a controller directly to a DOM element. By using a directive, you can effectively manage data passing between controllers without depending on global state, as many solutions utilizing services often do.

To achieve this, you should create a directive that can accept a certain configuration, which can then be passed through an attribute.

angular.module('yourApp').directive('yourList', function () {
  return {
    bindToController: true,
    controller: 'ListCtrl',
    controllerAs: 'list',
    scope: {
      params: '='
    }
  };
});

<div ng-controller="DashboardCtrl as dashboard">
  <your-list params="dashboard.listParams"></your-list>
</div>

The params property will now be accessible on the scope of ListCtrl. To handle the template used by your directive, you can opt for a separate partial, or you could utilize transclusion to maintain the elements in your main template.
