Restangular查询返回所有项目

问题描述：

我的api使用Django Rest Framework进行设置，我觉得我正在用Django尾随斜线进行操作。似乎有一些我没有想到的组合。基本查询总是返回api端点上的所有对象。Restangular查询返回所有项目

下面的代码：

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

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

    RestangularProvider.setBaseUrl('/api/'); 

    // Things I've tried 
    RestangularProvider.setBaseUrl('http://127.0.0.1:8000/api/'); 
    RestangularProvider.setRequestSuffix('/'); 
    // with suffix http://127.0.0.1:8000/api/tests/?value=404 
    // without suffix http://127.0.0.1:8000/api/tests?value=404 
    $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 
    console.log(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; 
});

我可以看到它试图去/测试PARAMS，但故障到测试/ PARAMS

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

也许我是结构？查询错误？有没有办法通过实际地址来测试查询？从技术上讲，不应该导航到http://127.0.0.1:8000/api/tests?value=404在DRF中只显示值为404的对象列表？ DRF在参数（http://127.0.0.1:8000/api/tests/?value=404）之前的url末尾输入斜杠。

有没有人有尝试过的方法来处理Django Rest Framework？

实际上我们需要看到DRF代码，特别是urls.py和views.py – pleasedontbelong

这是我想出来的。查询需要Django Rest Framework filtering。安装django过滤器后，您将filter_backends和filter_fields添加到您的视图。很好去。

$ 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; 
});
