How to add pagination in Restangular and Django Rest Framework? - angularjs

Question

In DRF I have added pagination limit to 100 'PAGINATE_BY': 100,
since Restangular expects results in array form, I had to use the below meta extractor function in my angular app module
var app = angular.module("myapp", ["restangular"].config(function(
RestangularProvider){
RestangularProvider.setResponseExtractor(function(response, operation, what, url) {
if (operation === "getList") {
var newResponse = response.results;
newResponse._resultmeta = {
"count": response.count,
"next": response.next,
"previous": response.previous
};
return newResponse;
}
return response;
});
});
and my controller looks like
app.controller('DataCtrl',function($scope, Restangular){
var resource = Restangular.all('myapp/api/dataendpoint/');
resource.getList().then(function(data){
$scope.records = data;
});
}
Meta info is not available in controller, how do I paginate if there are more than 100 records available?

I suppose you could simply call:
RestangularProvider.addResponseExtractor(function(data, operation, what, url, response) {
if (operation === "getList") {
data._resultmeta = {
"count": response.count,
"next": response.next,
"previous": response.previous
};
return data;
}
return response;
});
and
var page = 2;
var resource = Restangular.all('myapp/api/dataendpoint/');
resource.getList({page: page}).then(function(data){
console.log(data._resultmeta.next ? 'there is more pages' : 'You reach the end');
});
I'm not usual with Rectangular but Django Rest Framework support pagination from query parameter
