Preventing AngularJS from Binding in Rows: A Solution

Preventing AngularJS from Binding in Rows: A Solution

Currently, I am utilizing AngularJS version 1.5.3 and I am facing an issue with my services. I have two services - one that retrieves Area names and the other that fetches details for each Area. In my code, I first call the service to get the Area names and then set the ng-init to retrieve the details accordingly. The problem I'm experiencing is that Angular seems to only retain the first value for all the rows.

Below is the snippet of the code:

<tbody data-ng-repeat="area in vm.Areas" ng-init='vm.getDetails(area)'>
    <tr>
       <td class="text-bold">{{area}}</td>
       <td>{{vm.AreaDetails.Employees}}</td>
       <td>{{vm.AreaDetails.Hours}}</td>
       <td>{{vm.AreaDetails.Sales}}</td>
     </tr>
 </tbody>

Any suggestions on how to rectify this issue?

Thanks!

Avoid relying on ng-init in this scenario as it can heavily impact performance. Instead, consider fetching your data before the rendering process begins. For example:

vm.areas = vm.areas.map(function(area) {
  return area.details = service.getDetails(area);
}

@TJ has provided a technically correct answer, but I believe there is a design issue in your code that needs to be addressed.

Instead of loading each area and its details separately, it would be more efficient to load all of them at once.

For example, if you have 10 areas and your Detail service retrieves data from the server, this would result in 11 requests: 1 for all areas and 10 for the details of each area.

To optimize this process, consider making a single call to your service (and ultimately the server) to fetch all the necessary information and then use ng-repeat to display the data.

To streamline the process, the controller can loop through the different areas and invoke getDetails for each one. As soon as the details are fetched, they can be added to the corresponding area.

The bindings will look like this:

<tbody data-ng-repeat="area in vm.Areas">
 <tr>
   <td class="text-bold">{{area}}</td>
   <td>{{area.details.Employees}}</td>
   <td>{{area.details.Hours}}</td>
   <td>{{area.details.Sales}}</td>
 </tr>
</tbody>

Once the data is received, these bindings will automatically update.

Alternatively, you could create a directive with isolated scope, similar to the example below:

angular.module('yourModule').directive('areaInfo', function() {
  return {
    scope: {
      area: '=areaInfo'
    },
    require: "yourController", // controller where getDetails is stored
    templateUrl: "area-info.html",
    link: function(scope, element, attrs, ctrl) {
      scope.areaDetails = ctrl.getDetails(scope.area);
    }
  }
});

<script type="text/ng-template" id="area-info.html">
  <tr>
    <td class="text-bold">{{area}}</td>
    <td>{{areaDetails.Employees}}</td>
    <td>{{areaDetails.Hours}}</td>
    <td>{{areaDetails.Sales}}</td>
  </tr>
</script>
<tbody data-ng-repeat="area in vm.Areas" area-info="area"></tbody>

If needed, you can also transfer the getDetails method directly into the directive itself.
