Trigger the reactive helper again when there is a change in the $scope

I am working with a reactive data source in Angular-Meteor and I want to find a method to trigger the reactive function to run again after modifying another $scope value. Specifically, I aim to change the sorting order based on $scope.model.sort:

angular.module('...').controller('MyCtrl', [...], function(...){

    //Subscribe
    $scope.subscribe('articles');

    //Initialization
    $scope.model = {
        sort: 1,
        ...
    }

    //Reactive definitions
    $scope.helpers({
        articles: () => {
            console.log("+ articles");
            return Articles.find({...}, {sort: {colToSort: $scope.model.sort} });
        }
    });

Subsequently, I update the sorting order in the HTML or by calling a function:

ng-click="model.sort=-1"
ng-click="setSort(-1)"

JS

    $scope.setSort = function(sort) {
        console.log("+ setResourcesSort(%s)", sort);
        $scope.model.sort = sort;
    }

Unfortunately, neither of these approaches appears to trigger a re-run of the reactive helper. Is there a way to force the reactive helper to rerun when the referenced $scope.model.sort is altered?

Answer №1

perhaps consider including getReactively

  $scope.model = {
        sort: 1,
        ...
    }

    //Implementing reactivity
    $scope.helpers({
        articles: () => {
            console.log("+ articles");
            return Articles.find({...}, {sort: {colToSort: $scope.getReactively('model.sort')} });
        }
    });

Refer to the API documentation here for more information

Answer №2

For effective communication, the assistant must be proactive and engaged in dynamic discussions. Currently, it appears to lack this feature. While $scope is available as an assistant, it seems detached from any specific function. If integrated into a template helper, it will respond automatically to changes in scope. However, functioning alone (as seen currently), it will not update itself when the context shifts.
