AngularJS Question

Restangular query returns all items

My api is setup with Django Rest Framework and I feel like I am fighting with Django trailing slashes. There seems to be some combination that I have not figured out. A basic query always returns all the objects at the api endpoint.

Here's the code:

// App config
var App = angular.module('App',['App.controllers','restangular','ngRoute','ngResource']);

App.config(function ($interpolateProvider, $httpProvider, $resourceProvider, RestangularProvider) {


// Things I've tried
// with suffix
// without suffix
$resourceProvider.defaults.stripTrailingSlashes = false;

// In controller
// Items in database
// [{"itemID": 1,"value": 5,},{"itemID": 2,"value": 404,},{"itemID": 3,"value": 73,}]

var params = {'value': 404};
Restangular.all('tests').getList(params).then(function(items) {
var items = items

// Even the standard $resource does the same thing.
var Foo = $resource('/api/tests', {value:'@somevalue'});
$scope.allItems = {};
Foo.query({value:404}, function(items) {
$scope.allItems = items;

I can see it trying to go to /tests?params but it faults over to tests/?params

"GET /api/tests?value=404 HTTP/1.1" 301 0
"GET /api/tests/?value=404 HTTP/1.1" 200 361

Maybe I'm structuring the query wrong? Is there a way to test queries by actually going to the address? Technically shouldn't navigating to bring up in DRF only the list of objects with a value of 404? DRF puts in the slash at the end of the url before the parameters (

Does anyone have a tried and true method for working with Django Rest Framework?


Here's what I have figured out. Querying requires Django Rest Framework filtering. After installing django filter, you add filter_backends and filter_fields to your viewset. Good to go.

$ pip install django-filter

// In your serializers.py
// Create your serializer
from rest_framework import serializers
class FoobarSerializer(serializers.ModelSerializer):
    class Meta:
        model = Foobar
        fields = ('foo','bar')

// -----
// In your main app urls.py (or wherever you put your viewset, I have them in urls so most api stuff is collected there)
from rest_framework import routers
from rest_framework import viewsets
from rest_framework import filters
from mainapp.serializers import FoobarSerializer
from app.models import Foobar

// Put your filter fields in your viewset
class FoobarViewSet(viewsets.ModelViewSet):
    queryset = Foobar.objects.all()
    serializer_class = FoobarSerializer
    filter_backends = (filters.DjangoFilterBackend,)
    filter_fields = ('foo', 'bar')

// Register the viewset
router = routers.DefaultRouter()
router.register(r'foobars', FoobarViewSet)
urlpatterns = [
    url(r'^api/', include(router.urls)),

// -----
// In your angular controller.js
// Restangular
var params = {'foo': 404};
Restangular.all('foobars').getList(params).then(function(items) {
    $scope.items = items

// $resource
var Foo = $resource('/api/foobars', {value:'@somevalue'}); 
Foo.query({value:404}, function(items) {
    $scope.items = items;

// $http
$http({method:'GET',url:'/api/foobars',params:{value:404}}).then(function(response) {
    $scope.items = response.data;
