Could not load value into angular-bootstrap typeahead values with resources

I have a problem with angular-ui typeahead component. It does not show values populated by angular resources, however using $http works well. I suppose I missing some trick here with asycn call and correct population of returned values.
Working code
$scope.searchForContact = function(val) {
return $http.get('/api/contacts/search', {
params: {
q: val
}
}).then(function(response){
return response.data.map(function(item){
return item.name;
});
});
};
Not working code
$scope.searchForContact = function(val) {
return Contact.search({q: val}, function(response){
return response.map(function(item){
return item.name;
});
});
});
...
'use strict';
app.factory("Contact", function($resource, $http) {
var resource = $resource("/api/contacts/:id", { id: "#_id" },
{
'create': { method: 'POST' },
'index': { method: 'GET', isArray: true },
'search': { method: 'GET', isArray: true, url: '/api/contacts/search', params: true },
'show': { method: 'GET', isArray: false },
'update': { method: 'PUT' },
'destroy': { method: 'DELETE' }
}
);
return resource;
});
Pug template code
input.form-control(
type='text'
ng-model='asyncSelected'
uib-typeahead='contact for contact in searchForContact($viewValue)'
typeahead-loading='loadingLocations'
typeahead-no-results='noResults'
)
i.glyphicon.glyphicon-refresh(ng-show='loadingLocations')
div(ng-show='noResults')
i.glyphicon.glyphicon-remove
|
|No Results Found
Angular resources are working fine, including search endpoint - I just output on page result returned by the search endpoint. In both results should be just an array with string values. What am I doing wrong?

The difference between $http.get and your Contact.search is that the first one returns a promise and the latter doesn't. Any $resource method will usually be resolved to the actual response. I'll show that with an example.
Getting data with $http
var httpResult = $http.get('http://some.url/someResource').then(function(response) {
return response.map(function(item) { return item.name });
});
The httpResult object contains a promise, so we need to use then method to get the actual data. Moreover, the promise will be resolved to the mapped array, which is the expected result.
Getting data with $resource
var someResource = $resource('http://some.url/someResource');
var resourceResult = someResource.query(function(response) {
return response.map(function(item) { return item.name });
});
The resourceResult isn't a promise here. It's a $resource object which will contain the actual data after the response comes from the server (in short, resourceResult will be the array of contacts - the original, not mapped, even though there is a map function). However, the $resource object contains a $promise property which is a promise similar to one returned by $http.get. It might be useful in this case.
Solution
I read in documentation that in order to make uib-typehead work properly, the $scope.searchForContact needs to return a promise. Instead of passing the callback function to search, I would simply chain it with the $promise from $resource object to make it work.
$scope.searchForContact = function(val) {
return Contact.search({q: val}).$promise.then(function(response){
return response.map(function(item){
return item.name;
});
});
});
Let me know if it works for you.

AngularJS: Instance resource with POST errors out on promise

I am attempting to build a generic filter which needs to be able to handle - based on configuration - parameters. Both a resource instance and a service.
I have the following factory code:
angular.module('sample').factory('Sample', function($resource) {
var methods = {
search: {
method: 'POST',
isArray: true
}
}
var Sample = new $resource('/sample', methods);
Sample.prototype.elasticFilter = function (search) {
var query = {
query: {
filtered: {
query: {
wildcard: {
name: '*' + search.toLowerCase() + '*'
}
}
}
}
}
return this.$search(query);
}
return Sample;
});
Now if I do the following in my directive:
scope.search = function (search) {
Sample.elasticFilter(search).$promise.then(function () {
handle
});
this results in
TypeError: Cannot read property 'then' of undefined
printing out Sample.elasticFilter(search), the result is directly a Promise.
Modifying the directive to read directily off Sample.elasticFilter(search).then results in:
TypeError: value.push is not a function.
For non-instance-resources (e.g. NOT newed up, rather service directly), .$promise works fine.
Why is this happening? How can I work around it? When does a resource have a $promise, and when does it not?

This appears to be a "feature" https://github.com/angular/angular.js/issues/11767
The only way to really work around this is to not use isArray on instance level resource methods.

Error in resource configuration. Expected response to contain an object but got an array

I have an angular response that expects an array and the service call passes an array(can see it in network tab of chrome dev tools).
but I'm getting the following error in chrome console.
Error in resource configuration. Expected response to contain an object but got an array
here is my angular service:-
physicalServerModule.factory("physicalServerServices", ['$resource',
function ($resource) {
var host = app.general.host;
var port = app.general.port;
var serverItemPath = 'v1/physicalserver/:x';
var serverPath = 'v1/physicalserver/list';
return {
physicalServer: function () {
return $resource(host + serverPath,{}, {
query: {
method: 'GET',
isArray: true
},
create: {
method: 'POST'
}
});
}
};
}]);
and I'm calling my service as below:-
var tileServiceCall = physicalServerServices.physicalServer();
tileServiceCall.get({},{}).$promise.then(function (response) {
app.meta.physicalserver.tileItems = JSON.stringify(response);
}, function (error) {
alert("error");
});
my angularjs version is 1.2.15
can someone point me the root cause?

Change tileServiceCall.get(..) to tileServiceCall.query(...).

TypeError: undefined is not a function in Angular Resource

When trying to poll a custom method copies on an AngularJS Resource I get the following error at angular.js:10033: (The method copy works just fine.)

Simplified resource:
angular.module('vgm.content-pages')
.factory('ContentPage', function($resource, $http) {
return $resource('/api/content-page/:id', { id:'#page.id' }, {
copy: {
method: 'POST',
url: '/api/content-page/copy/:id'
},
copies: {
method: 'GET',
isArray: true,
url: '/api/content-page/copies/:id'
}
});
});
Simplified directive where I'm getting the error:
angular.module('vgm.genericForms')
.directive('vgmFormCopyPicker', function() {
return {
restrict: 'E',
replace: true,
templateUrl: '/static/common/generic-forms/widgets/view-copy-picker.html',
scope: {
resource: '=',
},
controller: function($scope, $element) {
$scope.pages = [];
$scope.loadCopies = function() {
$scope.resource.$copies()
.then(function(response) {
$scope.pages = response.data;
});
};
}
};
});
As soon as I run the loadCopies method, executing the line $scope.resource.$copies() throws the error above.
In the Chrome Inspector I see the call to my API is actually being done. But resolving the promise seems to throw some error...
How can I solve this error?
EDIT:
$scope.resource = ContentPage.get({id: $stateParams.id}).$promise
$scope.resource.$save() // Works
$scope.resource.$update() // Works
$scope.resource.$copy() // Works
$scope.resource.$copies() // Does not work!
Angular Resource is trying to overwrite my initial resource with an array of items. But the instance of Resource does not have a method push of course.

I found the answer:
A resource is supposed to represent the matched data object for the rest of its lifespan. If you want to fetch new data you should do so with a new object.
$scope.copies = ContentPage.copies()

The answer from Guido is correct but I didn't get it at the first time.
If you add a custom method to your Angular $resource and using isArray: true and expecting to get an Array of something from your WebService you probably want to store the response in an Array.
Therefore you shouldn't use the instance method like this:
var ap = new Ansprechpartner();
$scope.nameDuplicates = ap.$searchByName(...);
But use the resource directly:
$scope.nameDuplicates = Ansprechpartner.searchByName(...)
Using following Angular resource:
mod.factory('Ansprechpartner', ['$resource',
function ($resource) {
return $resource('/api/Ansprechpartner/:id',
{ id: '#ID' },
{
"update": { method: "PUT" },
"searchByName": { method: "GET", url: "/api/Ansprechpartner/searchByName/:name", isArray: true }
}
);
}
]);

I am using Mean.js and this plagued for a few hours. There is a built in $update but it was not working when I tried to apply it to an object returned by a $resource. In order to make it work I had to change how I was calling the resource to update it.
For example, with a Student module, I was returning it with a $resource into $scope.student. When I tried to update student.$update was returning this error. By modifying the call to be Students.update() it fixed the problem.
$scope.update = function() {
var student = $scope.student;
var result = Students.update(student);
if(result){
$scope.message = 'Success';
} else {
$scope.error =
'Sorry, something went wrong.';
}
};

Using AngularJS $resource to get data

I am trying to use $resource to get data from a static json file and here is the code snippet :
angular.module('app.services', ['ngResource']).
factory('profilelist',function($resource){
return $resource('services/profiles/profilelist.json',{},{
query:{method:'GET'}
});
});
In the controller,
function ProfileCtrl($scope,profilelist) {
$scope.items = [];
$scope.profileslist = profilelist.query();
for (var i=0;i<=$scope.profileslist.length;i++){
if($scope.profileslist[i] && $scope.profileslist[i].profileid){
var temp_profile = $scope.profileslist[i].profileid;
}
$scope.items.push(temp_profile);
}
But now, I am facing an error :
TypeError: Object #<Resource> has no method 'push'
Could you please help me where I am going wrong ?

You don't need to specify actions parameter for default $resource methods (these are 'get', 'save', 'query', 'remove', 'delete'). In this case you can use .query() method as is (this requires only service definition to be chaged):
angular.module('app.services', ['ngResource']).
factory('profilelist',function($resource){
return $resource('services/profiles/profilelist.json');
});
P.S. And one more hint is that your example unwrapped json into hash rather then array (that's why you received no push method error), if you need it to be an array set isArray: true to action config:
'query': {method:'GET', isArray:true}
And as #finishingmove spotted you really can't assign $resource result to obtain immediately, provide callback:
$scope.profileslist = profilelist.query(function (response) {
angular.forEach(response, function (item) {
if (item.profileid) {
$scope.items.push(item.profileid);
}
});
});
