Execute method in one of ng-repeat child

I'm using angular's ng-repeat to populate table with data from GitHub api and I want one of the to execute method that will return data. the problem is that this makes the function execute infinitely.


<tr ng-repeat="repo in repos">
<td></td> <!-- Get languages for each repo here. -->



var app = angular.module("githubViewer", []);

var MainController = function($scope, $http){

var onUserComplete = function(response){
$scope.user = response.data;
.then(onRepoComplete, onError);

var onRepoComplete = function(response){
$scope.repos = response.data;

var onError = function(reson){
$scope.error = "Could not fetch the data";

//search for user
$scope.search = function(username){
$http.get("https://api.github.com/users/" + username)
.then(onUserComplete, onError);

// These two execute infinately if executed in the ng-repeat's <td>
$scope.findLangs = function(langsUrl){
.then(onLangComplete, onError);

var onLangComplete = function(response){
return response.data;


app.controller("MainController", ["$scope", "$http", MainController]);


I've tried using {{ findLangs(repo.languages_url) }} in the but it causes me to get this error:

Error: [$rootScope:infdig] 10 $digest() iterations reached. Aborting!

and appears to be infinitely executing.


I don't think you can use an expression there because you don't actually return a value from the findLangs() function. That said, I don't think that would cause an infinite loop. I think you'll need to actually grab the language data for each repo within the onRepoComplete callback, then just use that data in your template:

var onRepoComplete = function(response){
  $scope.repos = response.data;
  $scope.repos.forEach(function(repo) {
      .then(function(response) {
        // change this to process the language data however you need to...
        repo.languages = JSON.stringify(response.data);

Then in your template you can use the languages property of the repo:

<tr ng-repeat="repo in repos">
