ng-repeat filter not applied - javascript

I have a simple code that pulls some data in intervals and prints into a table. I'd like to filter the table rows but any filters that I'm trying to apply are ignored. What am I missing? This is basically a plain copy from AngularJS docs page.
The only difference here seems to be that I'm using a controller and the example code does not.
Example Plunkr.
HTML template:
<table>
<thead>
<tr>
<th>Pages</th>
<th>Last action</th>
<th>Total time</th>
</tr>
<tr>
<th><input ng-model="search.count"></th>
<th><input ng-model="search.last"></th>
<th><input ng-model="search.time"></th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in adminCtrl.rows | filter:search ">
<td>{{ row.count }}</td>
<td>{{ row.last }}</td>
<td>{{ row.time }}</td>
</tr>
</tbody>
</table>
Controller:
(function(){
var app = angular.module('admin', []);
app.controller('AdminController', ['$interval', '$http', function($interval, $http){
var admin = this;
admin.rows = [];
var timer = undefined;
function updateRows() {
$http.get('test.json').success(function(data) {
admin.rows = data;
});
}
admin.stopTimer = function() {
if (angular.isDefined(timer)) {
$interval.cancel(timer);
timer = undefined;
}
};
admin.startTimer = function(delay) {
if (!angular.isDefined(delay)) {
// Default interval 10 seconds.
delay = 10000;
}
if (!angular.isDefined(timer)) {
timer = $interval(updateRows, delay);
}
};
admin.isTimerRunning = function() {
return angular.isDefined(timer);
}
// Initialize rows.
updateRows();
// Start the interval timer.
admin.startTimer();
}]);
})();

the filter is only apply in array where your data is an object. simply convert the data to array should work. if you happend to use lo-dash, that's a easy job to do :
function updateRows() {
$http.get('test.json').success(function(data) {
admin.rows = _.toArray(data);
});
}

It's because your ng-repeat is repeating over an object and not an array, here is your adminCtrl.rows:
{"a":{"count":14,"last":"Lorem ipsum","time":45},"b":{"count":5,"last":"Some title","time":13}}
Make it an array:
[{"count":14,"last":"Lorem ipsum","time":45},{"count":5,"last":"Some title","time":13}}]
If you want to use filter over an object, you'll have to roll your own using a
.filter("MY_FILTER", function(){
...
});

AngularJs:-
var appKitchenOrderReport = angular.module("myKitchenOrderReportApp", ['ngTable']);
appKitchenOrderReport.controller("myKitchenOrderReportCntrl", function ($scope, $window, $timeout, myKitchenOrderReportService, ngTableParams) {
var getData = myKitchenOrderReportService.SearchData($scope.CustomerName, $scope.Year);
getData.then(function (kitchenreportdata) {
var yearlyGridData = kitchenreportdata.data.OrderYearlyReport;
$scope.yearly_Table = new ngTableParams({
page: 1,
count: 10
}, {
total: $scope.yearlyGridData.length,
getData: function ($defer, params) {
$scope.YearlyReport = $scope.yearlyGridData.slice((params.page() - 1) * params.count(), params.page() * params.count());
$defer.resolve($scope.YearlyReport);
}
});
}, function () {
alert('Error in getting data');
});
});
appKitchenOrderReport.service("myKitchenOrderReportService", function ($http) {
this.getKitchenOrderReportData = function () {
var response = '';
return $http.get("GetOrderReport"); };
this.SearchData = function (CustomerName, Year)
{
var GetParams = new Object();
GetParams.CustomerName = CustomerName;
GetParams.Year = Year
var response = $http({
method: "post",
url: "GetOrderReport",
data: '{model: ' + JSON.stringify(GetParams) + '}',
});
return response;
}
});
you can Use $('#myYealyGrid').DataTable(); to initialize your datatable .
But Use just befor , when you Put data into the HTML table .
It will automatically initialize your Datatable.
Try it and let me know is it working or not .

Dynamic table with JSON data and sticky collapsible rows

I'm using Angular 1 with a factory that polls a REST API for JSON data. This JSON then populates a table with ng-repeat-start, and using ng-repeat-end I have a hidden table row with additional data.
Seems rather ordinary to me.
But the problem is, when I poll the API every 5 or 10 seconds, how can I keep the collapsible table row open when the next poll occurs?
In most cases the data does not change, so there's no reason to close the collapsible row, yet it closes at every poll that my factory makes.
Here's an example of one of the tables.
<table class="pure-table pure-table-horizontal alerts-table" id="alert-nagios-host-table">
<thead>
<tr>
<th>Hostname</th>
<th>Status</th>
<th>Output</th>
</tr>
</thead>
<tbody>
<tr class="parent-row" ng-repeat-start="alert in alerts" ng-click="child.expanded = !child.expanded">
<td>{{alert.hostname}}</td>
<td ng-class="{3:'grayBg', 2:'redBg', 1:'yellowBg', 0:'greenBg'}[alert.state]">{{alert.status}}</td>
<td>{{alert.output}}</td>
</tr>
<tr class="child-row" ng-init="child.expanded = false" ng-show="child.expanded" ng-repeat-end>
<td colspan=4>Duration: {{alert.duration}}</td>
</tr>
</tbody>
</table>
Here is my factory that polls the data, and an example of one of the angular controllers.
mondashApp.factory('AlertsPoller', function ($http, $timeout) {
var data = {resp: {}, count: 0};
var count=0;
var poller = function (url, success) {
count++;
$http.get(url).then(function (responseData) {
data.count = count;
data.resp = responseData.data;
success(data);
$timeout(function () {poller(url, success);}, 5000);
});
};
return {
poller: poller
};
});
mondashApp.controller('nagiosHostAlertsCtrl', function nagiosHostAlertsCtrl($scope, AlertsPoller) {
AlertsPoller.poller('/alert/nagios/host', function(response) {
$scope.alerts = response.resp.alerts;
});
});

AngularJS view not updated after model updates

New to Angular, I am trying to save a form and update the view after calling a PUT or POST call to the backend. Once I receive an OK status from the backend, I am updating my models with the latest response. But only the model in the directive "ng-click" gets updated but others do not. Here is my code:
///HTML
<table class="footable table table-stripped toggle-arrow-tiny" data-page-size="8">
<thead>
<tr>
<th data-toggle="all">Release Title</th>
<th data-hide="all">Release Genre</th>
<th data-hide="all">UID</th>
<th data-hide="all">Classical</th>
<th data-hide="all">Tracks</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="album in vm.albums" footable>
// This one (album.data.title) gets updated but the other ones do not
<td ng-click="vm.editAlbum(album, $index)">{{album.data.title}}</small></td>
<td>{{album.data.genre}}</td>
<td>{{album.data.uid}}</td>
<td ng-if!="album.data.classical">No</td>
<td ng-if="album.data.classical">Yes</td>
<td>
<li ng-repeat="track in album.data.tracks">
<a ng-click="vm.selectTrack(album, track)">{{track.title}}</a>
</li>
</td>
</tr>
</tbody>
<tfoot>
<tr>
<td colspan="5">
<ul class="pagination pull-right"></ul>
</td>
</tr>
</tfoot>
</table>
Here is my controller:
// controller.js (Just pasting the saveRelease method that does the on-click event handling in HTML:
(function (){
angular.module('app.uploadedReleases').controller('UploadedReleasesController', UploadedReleasesController);
UploadedReleasesController.$inject = ['$http', '$log', '$scope', '$state', '$rootScope', 'APP_CONFIG'];
function UploadedReleasesController ($http, $log, $scope, $state, $rootScope, APP_CONFIG){
var vm = this;
vm.albums = []; // list of all albums
vm.albumPriority = [0, 4, 6, 8, 10];
vm.getAlbumTracks = getAlbumTracks;
vm.editAlbum = editAlbum;
vm.selectTrack = selectTrack;
vm.selected = {};
vm.saveRelease = saveRelease;
vm.testingAlbumSelected = false;
return init();
function init(){
$http.get('http://localhost:8080/api/releases').then(function(responseData){
//check the status from the response data.
vm.responseStatus = responseData.status;
if(vm.responseStatus !== 200){
//error message
}
// else, Parse the json data here and display it in the UI
for(var album in responseData.data){
vm.albums.push({slug: album, data: responseData.data[album]});
}
})
}
function getAlbumTracks(slug, index){
$http.get('http://localhost:8080/api/releases/' + slug).success(function(trackResponse){
//parse each album and get the track list
vm.showingAlbumIndex = index;
vm.albums.tracks = [];
vm.selected = {};
vm.selected.album = vm.albums[index];
vm.testingAlbumSelected = true;
for(var i = 0; i<trackResponse.tracks.length; i++) {
vm.albums.tracks.push(trackResponse.tracks[i]);
}
$log.debug(vm.albums.tracks);
vm.formAlbum = new Album(vm.selected.album.data.upc,
vm.selected.album.data.title,
vm.selected.album.data.label,
vm.selected.album.data.genre,
vm.selected.album.data.releaseType,
vm.selected.album.data.holdDate,
vm.selected.album.data.priority,
vm.selected.album.data.memo);
})
}
function selectTrack(album, track){
vm.selected.album = album;
vm.selected.track = track;
vm.testingAlbumSelected = false;
}
function editAlbum(album, index){
getAlbumTracks(album.slug, index);
vm.selected = album;
}
function saveRelease(){
// Call the PUT request to update the release metadata and refresh the page
// so that the Album list gets updated with the latest changes
var url = 'http://localhost:8080/api/releases/' + vm.selected.album.slug;
$http.put(url, vm.formAlbum).then(function(saveAlbumResponse){
if(saveAlbumResponse.status === 202){
//successfully saved response on backend
// Update the current models to show the newer data
vm.album.data = vm.formAlbum;
console.log("album array vm.albums = "+vm.albums);
}
})
}
})();
Any idea why ?
try remove "var vm=this" line. And rename vm.xxxx to $scope.xxxx in your controller.
in the view: remove the "vm."

Angular - link two API sources in table based on ID FK

I'm really new to Angular and i'm trying to create a list of user transactions that presents the time of the action and the user's name. In my audit API I have an action ID and the User FK which associates with my User API and i'm displaying it as follows:
HTML
<table>
<thead>
<tr>
<th>
Date/Time
</th>
<th>
User
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="audit in audit.data>
<td>{{audit.audit_date_time}}</td>
<td>**{{audit.audit_user_fk}}**</td> **<--I need the name not the ID here**
</tr>
</tbody>
</table>
My Apis are as follows:
AUDIT
[
{
"audit_id": "1",
"audit_date_time": "2016-01-28 12:46:20",
"audit_user_fk": "97"
}
]
USER
[
{
"user_id": "97",
"user_full_name": "Mr.User",
}
]
Controller, which is working fine GETting the data from each API:
app.controller('auditControl', ['$scope','auditService', 'userService', function ($scope, auditService, userService) {
var auditLogs = auditService.query(function () {
$scope.audit.data = auditLogs;
});
var user = userService.query(function () {
$scope.auditUser = user;
});
}]);
So my main issue i'm having is getting the user name in the table instead of the foreign key value. I've stripped out a lot of this just so we can focus on the main problem. Getting the user name from the user API, based on the FK in the Audit API and repeated based on the items in the Audit API.
Any help greatly appreciated and apologies for the noob question!
Create a custom filter.
app.filter("lookupUser", function() {
function lookup (idNum, userList) {
var userName = "UNKNOWN";
angular.forEach(userList, function(user) {
if ( user.user_id == idNum ) {
userName = user.user_full_name;
};
});
return userName;
};
return lookup;
});
Then in your template:
<tr ng-repeat="audit in audit.data>
<td>{{audit.audit_date_time}}</td>
<td>{{audit.audit_user_fk | lookupUser : auditUser }}</td>
</tr>
You could do something like this:
Controller:
app.controller('auditControl', ['$scope','auditService', 'userService', function ($scope, auditService, userService) {
var auditLogs = auditService.query(function () {
$scope.audit.data = auditLogs;
});
var user = userService.query(function () {
$scope.auditUser = user;
});
$scope.getUserName = function (id) {
var result = $scope.users.filter(function( user ) {
return user.user_id == id;
});
if (angular.isDefined(result) && result.length > 0) {
return result[0].user_full_name;
} else {
return "--";
}
}
}]);
HTML
<table>
<thead>
<tr>
<th>
Date/Time
</th>
<th>
User
</th>
</tr>
</thead>
<tbody>
<tr ng-repeat="audit in audit.data">
<td>{{audit.audit_date_time}}</td>
<td>**{{getUserName(audit.audit_user_fk)}}**</td> **<--I need the name not the ID here**
</tr>
</tbody>
</table>
I don't know where the users array are, so I called $scope.users.

AngularJS orderBy Function With No Sorting

I am attempting to use a custom orderBy function. Initially, I want the data to appear in the order it was added to $scope.rows, and only after clicking on a column heading should it order by a specific property. Here's my fiddle:
http://jsfiddle.net/S8M4c/
Here's my view:
<table ng-app ng-controller="ctrl">
<tr>
<th><a ng-click="orderBy = 'id'">ID</a></th>
<th><a ng-click="orderBy = 'name'">Name</a></th>
</tr>
<tr ng-repeat="row in rows | orderBy:mySort">
<td>{{row.object.id}}</td>
<td>{{row.object.name}}</td>
</tr>
</table>
Here's my controller:
function ctrl($scope)
{
// Initially, we don't sort by anything
$scope.orderBy = "";
$scope.rows = [];
// Add some rows
for(var i = 10;i < 30;i++)
{
$scope.rows.push({settings: {foo: true}, object: {id: i, name: "Name " + i}})
};
$scope.mySort = function(row)
{
if($scope.orderBy != "")
{
return row.object[$scope.orderBy];
}
// What do I return here??
return "";
}
}
In the case that $scope.orderBy isn't set and I want to return $scope.rows in it's original order, what do I return in $scope.mySort? I cannot return row.object.id because the rows are not guaranteed to be added in order of their ID. Running my code as is on Chrome 32, the first row that appears has an ID of 20, which is the halfway row.
return $scope.rows.indexOf(row);
(Fiddle.)
You can also do this with out-of-the-box orderBy by providing a function returning that as the default predicate:
Controller:
$scope.mySort = $scope.unsorted = function(row)
{
return $scope.rows.indexOf(row);
}
View:
<div ng-app ng-controller="ctrl">
<table>
<tr>
<th><a ng-click="mySort = 'object.id'">ID</a></th>
<th><a ng-click="mySort = 'object.name'">Name</a></th>
</tr>
<tr ng-repeat="row in rows | orderBy:mySort">
<td>{{row.object.id}}</td>
<td>{{row.object.name}}</td>
</tr>
</table>
<button ng-click="mySort = unsorted;">Original Sort</button>
</div>
Fiddle here. (I've changed the numbers used in the objects so that sort by id, sort by name, and the original sort aren't all the same.)
I think you have to write your own sortby function. The original angulars orderBy is a regular filter that returns the sorted array. Your filter may look something like this:
.filter('mySort', function(){
return function(values, param){
if(param===''){
return values;
}else{
// very important! create a copy of the array - otherwise
// the $wtachCollection function will fire to often!
var arrayCopy = [];
for ( var i = 0; i < values.length; i++) { arrayCopy.push(values[i]); }
return arrayCopy.sort(function(a,b){
var v1 = a.object[param];
var v2 = b.object[param];
// you know best how to sort it!
if (v1 === v2) return 0;
return v1 < v2 ? -1 : 1;
});
}
}
})
You can use this filter in this way:
<table ng-app="myApp" ng-controller="ctrl">
<tr>
<th><a ng-click="orderBy = 'id'">ID</a></th>
<th><a ng-click="orderBy = 'name'">Name</a></th>
</tr>
<tr ng-repeat="row in rows | mySort:orderBy">
<td>{{row.object.id}}</td>
<td>{{row.object.name}}</td>
</tr>
</table>
here is your modified fiddle: http://jsfiddle.net/spRf6/ I have changed the names a little bit so you may see that the sorting works.
Create a copy of the objects array and the ordering then becomes trivial:
Controller:
$scope.objects = [];
angular.forEach($scope.rows, function(row){
$scope.objects.push(row.object);
});
View:
<tr ng-repeat="object in objects | orderBy:orderBy">
<td>{{object.id}}</td>
<td>{{object.name}}</td>
</tr>
No need for the mySort function.
