ng-table encountered an error: Unable to assign a value to the property '$data' because it is null

Currently, I am utilizing ng-table to showcase data fetched from an API call that I organize similarly to the example provided on the website.

However, unlike the example on the website which uses static information, I need to make a fresh API call each time. Without including the $

scope.$watch('groupby', function(value)
function, I can successfully display the table for the initial call.

angular.module('myApp.controllers', ['ngTable','ui.bootstrap','dialogs'])
.controller('HomeCtrl', function($scope,$log, $rootScope, $modal, TimeService, EventServiceAPI, $filter, ngTableParams) {
    var datum = new Date().setHours(0,0,0,0);
    $scope.datum = datum;
    var timestamp = Math.round(new Date().getTime()/1000);

    // Rest of the controller code...

UPDATE:

I have managed to display the data successfully; however, the groups are not being shown:

var datum = new Date().setHours(0,0,0,0);
    $scope.datum = datum;
    var timestamp = Math.round(new Date().getTime()/1000);

    EventServiceAPI.query({start: timestamp, end: timestamp + 3*24*60*60}).$promise.then(function(data) { $scope.data = data; initlizeTable(); });

    // Rest of the updated code snippet...

Answer №1

Although it may be overdue, I wanted to share my solution for anyone else facing the same issue.

After encountering the same problem, I was able to resolve it by using the example provided in the link below.

https://github.com/esvit/ng-table/blob/master/src/scripts/04-controller.js

I simply inserted the following line of code into my script after creating the 'ngTableParams' instance.

$scope.params.settings().$scope = $scope;

Answer №2

That was the turning point for me. I made a crucial addition to the scope within the params.settings.

controller: function() {
...
 $scope.myTableParams = new ngTableParams({
.
},{
...
getData: function ($defer, params) {
   if (params.settings().$scope == null) {
         params.settings().$scope = $scope;
   }
.
.
}
