I'm using $resource in angular to get json object and its structure is defined below
[
{
"id": 0,
"name": "Type1"
},
{
"id": 1,
"name": "Type 2"
}
]
after fetching the data .. console.log(jsonObject) gives me
[Resource, Resource, $promise: Object, $resolved: true]
How can I remove $promise & $resolved from the resulting object ? I tried angular.fromJson(json) but still I see that these objects still exist.
I'm looking for the same answer, but at this moment I know only this ugly hack:
To write a func like this:
function cleanResponse(resp) {
return JSON.parse(angular.toJson(resp));
}
and call it in every single query (ugly, yep):
function getSmt() {
Resource.get({}, function (data) {
$scope.some = cleanResponse(data);
}, function (responce) {
//handle error
})
}
I'll be happy if someone would teach me how to do it correctly
Example from my project
Diary.getSharedWithMe(function(data) {
delete data.$promise;
delete data.$resolved;
_self.sharedDiariesWithMe = data;
}, function(error) {
console.log(error)
});
从这个答案 ,它看起来yourResource.toJSON()
随时可用。
Right, I've faced the same problem several times and always ended up using $http instead of $resource, however , today I decided to try and deal with this issue. I hope somebody will find this useful one day as well.
So, after you receive your object with $promise inside of it, what you do is just use angular.copy(data)
, like so:
someService.getSomething($scope.someId).$promise.then(function (data) {
if (data) {
$scope.dataWithoutPromise = angular.copy(data);
}
});
After that, you will see that your dataWithoutPromise
just contains the objects that you need, and $promise and $resolved are gone.
I'm facing the same issue. In fact, you simply have to use the same version of angular and angular-resource and it will work like a charm. Hope it helps !
Short answer : angular.fromJson(angular.toJson(resp)); This will remove all "angular specific" functions etc and will return you a clean data object.
Are you using isArray
or .query()
with your $resource
object?
From the $resource docs: isArray – {boolean=} – If true then the returned object for this action is an array.
UPDATE:
If you are using $resource
correctly, some options you have are:
1) Have the backend return the data contained within an object, eg. { data: [] }
rather than just an array.
2) If that is not possible, use the callback from the $resource.query()
, eg.
MyResource.query({ myParams: 'something'}, function(result) {
// Do something with the plain result
});
I did this quick reusable method for angular.toJson (Properties with leading $$ will be stripped):
yourApp.factory('Service', ['$resource', function ($resource) {
return $resource('your/rest/api/path');
}]);
yourApp.factory('commonServices', function () {
return {
toJson : function(response){
return JSON.parse(angular.toJson(response));
//*or*
//return angular.toJson(response);
}
});
And then something like this in your controller:
yourApp.controller('Controller', ['$scope', 'Service','commonServices',
function ($scope, Service, commonServices) {
Service.get().then(function (data) {
$scope.myData = commonServices.toJson(data);
});
});
the more simple way is to add angular.toJson in the controller
yourApp.controller('Controller', ['$scope', 'Service',
function ($scope, Service, commonServices) {
Service.get().then(function (data) {
$scope.myData = angular.toJson(data);
});
});
Please simply do this:
jsonObject.$promise = undefined; jsonObject.$resolved = undefined;
$promise and $resolved will not be removed but you will be able to do what you want.
Try to code something like this in your service:
yourApp.factory('Service', ['$resource', function ($resource) {
return $resource('your/rest/api/path');
}]);
And then something like this in your controller:
yourApp.controller('Controller', ['$scope', 'Service', function ($scope, Service) {
Service.get().then(function (data) {
$scope.myData = data;
});
});
