In my AngularJS project I'm trying to use the Restangular getList method but it's returning an error because the API response is not directly an array but an object containing an array.
{ "body": [ // array elements here ], "paging": null, "error": null } The Restangular error message is:
Error: Response for getList SHOULD be an array and not an object or something else Is it possible to tell Restangular that the array it's looking for is inside the body property?
Yes, see the Restangular documentation. You can configure Restangular like so:
rc.setResponseExtractor(function(response, operation) { if (operation === 'getList') { var newResponse = response.body; newResponse.paging = response.paging; newResponse.error = response.error; return newResponse; } return response; }); Edit: It seems Restangular's API is now changed, for the better, and that the current method to use is addResponseInterceptor. Some adjustments might be needed to the function passed.
I think you should use a the customGET from the Custom Methods
Restangular.all("url").customGET(""); // GET /url and handle the response as an Object
as Collin Allen suggested you can use addResponseInterceptor like this:
app.config(function(RestangularProvider) { // add a response intereceptor RestangularProvider.addResponseInterceptor(function(data, operation, what, url, response, deferred) { var extractedData; // .. to look for getList operations if (operation === "getList") { // .. and handle the data and meta data extractedData = data.body; extractedData.error = data.error; extractedData.paging = data.paging; } else { extractedData = data.data; } return extractedData; }); });
