Why can't I display records with ngTable

Question

I was trying to display records on html using ngTable. The records are retrieved from server side through rest api.

html:

<div class="container">
        <table ng-table="tableParams" class="table" show-filter="false">
            <tr ng-repeat="report in $data">
                <td title="'ReportId'" filter="{ reportid: 'text'}" sortable="'reportid'">
                    {{report.reportid}}</td>
                <td title="'SampleId'" filter="{ sampleid: 'text'}" sortable="'sampleid'">
                    {{report.sampleid}}</td>
                <td title="'MRN'" filter="{ mrn: 'text'}" sortable="'mrn'">
                    {{report.mrn}}</td>
                <td title="'Diagnosis'" filter="{ diagnosis: 'text'}" sortable="'diagnosis'">
                    {{report.diagnosis}}</td>
            </tr>
        </table>
    </div>

Controller.js

ristoreApp.controller("fmCtrl",
    ['$scope', 'fmFactory', 'NgTableParams', function($scope, fmFactory, NgTableParams) {
        $scope.selection = '0';
        $scope.fmSearch = function () {
            if ($scope.selection == '0') {
                $scope.tableParams = new NgTableParams({
                    page: 1,            // show first page
                    count: 10          // count per page
                }, {
                    getData: function (params) {
                        return fmFactory.getAll().then(function(data) {
                            params.total(data.inlineCount);
                            return data.results;
                        });
                    }
                });
                $scope.tableParams.reload();
            }
        }
    }]
)

Factory js

ristoreApp.factory("fmFactory", ['$http', '$window',
    function ($http, $window) {
        var service = {};

        service.getAll = function () {
            var url = SERVER + "/ristore/foundation/";
            return $http({
                headers: {'Authorization': 'Bearer ' + $window.localStorage.getItem("access_token")},
                url: url,
                method: 'GET',
                crossOrigin: true
            })
        }

        return service;
    }]);

The factory definitely returns records from server correctly, because when I debug it, it shows the data of the response.

However it does not show anything on the page. What went wrong?

Answer 1

Do these things

1. Change $scope.tableParams in controller to this.tableParams
2. Change <div ng-controller="fmCtrl"> in view to <div ng-controller="fmCtrl as fm">
3. Change ng-table="tableParams" in view to ng-table="fm.tableParams"

Documentation: http://ng-table.com/#/loading/demo-external-array

Update 1: Change the return rmFactory.getAll() like this,

return fmFactory.getAll().then(function(response) {
    var reports = response.data;
    params.total(reports.length);
    return reports;
});

Update 2: Add this line to controller beginning (first line)

var self = this;

The first change we made, rewrite it like this.

self.tableParams

Update 3: We removed $scope and used this because the documentation was using that. this did not work here because, we were inside $scope.fmSearch. So to get this of the controller, we stored it in a variable self and accessed it. You can rename self to any name of your choice.
