Angular - abort ajax request when using Restangular

angularjs, restangular

Solution

You can abort `$http` calls via the `timeout` config property, which can be a Promise, that aborts the request when resolved.

So in restangular, you can do this like

var abort = $q.defer();
Restangular.one('foos', 12345).withHttpConfig({timeout: abort.promise}).get();
abort.resolve();

To integrate it with your usecase, for example, you could have this in your service:

var abortGet;

this.getRecords = function(params) {
  ...
  if (abortGet) abortGet.resolve();
  abortGet = $q.defer();
  return Restangular
    .all('/api/records')
    .withHttpConfig({timeout: abortGet.promise})
    .post(filters);
}

This way calling `getRecords` always aborts the previous call if has not been resolved yet!

Problem

I have a method that calls an angular service and consequently makes an ajax request via the service. I need to make sure that if this is called several times, the previous request in aborted (if it hasn't already been resolved that is). This method can get called multiple times. This method is actually from ngTable on `ngTableParams`: ``` getData = function($defer, params) { myService.getRecord(params).then(function(res){ ... $defer.resolve(res.Records); }); } ``` Here's the method on the service: ``` this.getRecords = function(params) { ... return Restangular .all('/api/records') .post(filters); }; ``` If ngTable makes 3 calls I want the first 2 to be aborted (unless of course they returned so fast that it got resolved)
