ng repeat after postDigest not working - html

I am trying to load data from list to repeater but its not working the data is returning, list of students but its not showing on screen.
Controller:
$scope.students=[];
$scope.$$postDigest(function () {
$http.get("/getAllStudents"/*, {timeout: canceler.promise}*/).
then(function (response, status, headers, config) {
if (response.data) {
$scope.students=response.data;
}
});
});
HTML:
<tr ng-repeat="student in students">
<td contenteditable="true">{{student.Id}}</td>
<td contenteditable="true">{{student.FullName}}</td>
<td contenteditable="true">{{student.Gender}}</td>
<td contenteditable="true">{{student.Grade}}</td>
</tr>

When the $http.get the call is made in the postDigest, it seems the data is successfully inserted inside the $scope.students. Please check if there is any scope issue, because as per the details provided, it should work until and unless you're missing to mention any other details.

Bind first value and remove all other repeating value from a ng-repeat

I have a scenario to bind a html table using angular js. In my table i need to show an a tag based on another column value(Payment Status). If its fully paid no need to show the a tag, else need to show it for very next element. I am a new one in angular.
<table>
<thead>
<tr>
<th>Month</th>
<th>Installement</th>
<th>PaymentAmount</th>
<th>PaymentDate</th>
<th>Payment Status</th>
<th>Pay</th>
</tr>
</thead>
<tbody>
<tr dir-paginate="row in rowCollection|orderBy:type:reverse|filter:searchKeyword|itemsPerPage:maxsize">
<td>{{row.Month}}</td>
<td>{{row.MonthlyInstallement}}</td>
<td>{{row.PaymentAmount}}</td>
<td>{{row.PaymentDate}}</td>
<td>{{row.PaymentStatus}}</td>
<td ng-if="row.PaymentStatus == 'UNPAID'">
Pay Online
</td>
<td ng-if="row.PaymentStatus == 'FULLY_PAID'">
</td>
</tr>
</tbody>
</table>
function bindFinanceDetails() {
var finUrl = baseurl + 'api/FinancialStatement/GetCarFinanceInfo';
var req = {
method: 'post',
data: {
LoginID: LoginID,
ContractNumber: 11170200669,
CustomerId: 2355898046
},
url: finUrl,
headers: {
RequestedPlatform: "Web",
RequestedLanguage: cookiePreferredLanguage,
Logintoken: $cookieStore.get('LoginToken'),
LoginId: LoginID
}
};
$http(req).then(function(response) {
var getData = response.data.FinanceList;
$scope.rowCollection = getData;
}, function(error) {
toastr.error($filter('translate')('Error Occured'));
});
}
A quite hacky solution will be something like the following (just showing you the needed change in the unpaid td element):
<td ng-if="row.PaymentStatus === 'UNPAID'" ng-show="$index === data.payOnlineIndex"
ng-init="data.payOnlineIndex = (!data.payOnlineIndex || (data.payOnlineIndex > $index)) ? $index : data.payOnlineIndex">
Pay Online
</td>
This way ng-init will run for all unpaid elements, setting the smallest index to the payOnlineIndex variable. ng-show will make sure to only show that one element that has the smallest index.
I encapsulate payOnlineIndex with a data object to keep a stable reference to it. This also requires the following addition to the controller code:
$scope.data = { payOnlineIndex: null };
See a working jsFiddle example here: https://jsfiddle.net/t3vktv0r/
Another option is running your filter and orderBy in the controller, searching for the first occurrence of an "unpaid" row, and marking that element for the "pay online" feature with some flag you can test with ng-if in your view.

JQuery Datatable not loading Json data from MVC Controller

I have an Asp.Net MVC 5 web application. I am using JQuery Datatables v1.10.16 to display tabular data within one of the razor views. The data being returned to the datatable is via an ajax call and returning Json.
This is my razor view
<table id="data_table" class="display" style="width:100%">
<thead>
<tr>
<td>Evaluation ID</td>
<td>Applicant Name</td>
</tr>
</thead>
<tfoot>
<tr>
<td>Evaluation ID</td>
<td>Applicant Name</td>
</tr>
</tfoot>
</table>
<script type="text/javascript">
$(document).ready(function () {
$('#data_table').DataTable({
"ajax": '/EvalDashboard/GetEvaluationData',
"dataSrc": 'evaluations',
"columns": [
{ data: 'evaluationID' },
{ data: 'applicantName' }
]
});
});
</script>
This is my method which is called inside the controller EvalDashboard
public JsonResult GetEvaluationData()
{
var evaluations = _evalService.GetAllCecEvaluations(null, null)
.Take(20).Select(x => new
{
evaluationID = x.EvaluationID,
applicantName = x.tblcourseapplicant.FullName
}).ToList();
return Json(evaluations, JsonRequestBehavior.AllowGet);
}
When I run the app, I can see that the method GetEvaluationData() is being called, however, no data is returned to the datatable in the view, I only get a message saying Loading...
I'm not sure if the problem is because I'm returning an annonymous type inside my method.
Could someone please help?
Thanks.
The problem was that I had not included the keyword data inside the Json return statement like so:
return Json(new { data = evaluations }, JsonRequestBehavior.AllowGet);
This fixed the problem I was having.

create dynamic html table with dynamic tr ,td using angularjs

how can I create an html table from a json file, which I do not know the number of columns or the number of rows (the number of row ng-repeat enough),
this json file is editable and the number of column and row change
You would need to load your JSON file into your app with either the $http or $resource service. This is best done in a service, which you would inject whereever you need your data.
this.getJson = function() { // real json get
$http.get('/api/GetJson').then(function(data) {
return data;
});
};
I created a small plunker with a service that holds my fake getJson function which returns the json data with the rows. Then I injected the service into my HomeController and put the rows on the $scope.
$scope.rows = loadJsonService.getFakeJson().rows;
When the rows are on the $scope, you only have to use the ngRepeat directive to create your table structure.
<table class="table table-striped">
<tr class="row" ng-repeat="row in rows">
<th>row {{$index + 1}}</th>
<td class="column" ng-repeat="column in row.column">{{column}}</td>
</tr>
</table>

send data from two models of Mongoose inside Express.js to display in view list data

I have a Shopping Website I want to be able to display two model names "jeans" and "shirt" in a view
I need to pass data from two models I know how to access data from two models in one controller but I do not know how to send data from that controller
Controller:
var mongoose = require('mongoose'),
errorHandler = require('./errors.server.controller'),
Shirt = mongoose.model('Shirt'),
Jeans = mongoose.model('Jeans');
exports.list = function(req, res) {
Jeans.find().sort('-created').populate('user', 'displayName').exec(function(err, jeans) {
Ajean = jeans;
});
Shirt.find().sort('-created').populate('user', 'displayName').exec(function(err, shirts) {
Ashirt = shirts;
});
Shirt.find().sort('-created').populate('user', 'displayName').exec(function(all) {
// res.jsonp(Ashirt);
// res.jsonp(Ajean);
});
};
View:
<div class="list-group">
<table class="table table-striped table-bordered">
<thead>
<tr>
<th>Name</th>
<th>Color</th>
</tr>
</thead>
<tbody>
<tr data-ng-repeat="item in items">
<td data-ng-bind="item.name"></td>
<td data-ng-bind="item.color"></td>
</tr>
</tbody>
</table>
</div>
I know that I cannot use "res.jsonp();" more than once .
when I use "Ajean" it give me data for "jeans" and
when I use "Ashirt" it give me data from "shirts" model
But I want to be able to show both data from both "shirt" model and "jean" model
How Can I do That?
Do I need to merge two Json?
How should I change my view to see that data?
Thanks!
You could try nesting the queries and then merge the resulting arrays with Array.concat:
Jeans.find().sort('-created').populate('user', 'displayName').exec(function(err, jeans) {
Shirt.find().sort('-created').populate('user', 'displayName').exec(function(err, shirts) {
var all = shirts.concat(jeans);
res.jsonp(all);
});
});

parse html within ng-repeat

I've been searching for hours now and I can't seem to find how to parse HTML code when retrieving using ng-repeat. I checked out $sce.trustAsHtml but I don't know how to apply it in my code.
html file:
<div ng-app="myApp">
<div ng-controller="MyCtrl">
<h2>My Links</h2>
<table class="table table-bordered">
<thead>
<tr>
<td>Name</td>
<td>URL</td>
</tr>
</thead>
<tbody>
<tr ng-repeat="stuff in myStuff()">
<td>{{stuff.name}}</td>
<td>{{stuff.url}}</td>
</tr>
</tbody>
</table>
</div>
javascript
var myApp = angular.module('myApp', []);
myApp.controller('MyCtrl', function ($scope) {
$scope.myStuff = function() {
return [
{
'name':'Google',
'url':'Google'
},
{
'name':'Yahoo',
'url':'Yahoo'
},
{
'name':'Microsoft',
'url':'Microsoft'
}
];
};
});
It's displaying the HTML source but I want it compile the code. Is my JS approach wrong? I'll be applying it to a json file using $http directive once I figure this out. Can anyone shed some light? I have my code at http://jsfiddle.net/s2ykvy8n/
Thanks.
Include ng-sanitize script and in your module add dependency.
var myApp = angular.module('myApp', ['ngSanitize']);
and just use ng-bind-html
<td ng-bind-html="stuff.url"></td>
and you are good to go:-
Plnkr
With what you are doing, the html in the binding will be displayed as textcontent in the element while processed by interpolation directive.
My first inclination (since from your example, you are just returning links) is to advise you to remove the html from your returned json and just return the url as a string.
Format:
{
'name': 'Google',
'url': 'http://google.com'
}
Then your HTML looks like this,
<tbody>
<tr ng-repeat="stuff in myStuff()">
<td>{{stuff.name}}</td>
<td>{{stuff.name}}</td>
</tr>
</tbody>
But, if you MUST have HTML strings in your json file, I would take a look at $compile. There are examples towards the bottom that can help you on how you can create a directive to compile your 'url' string to HTML
