class Photo(models.Model):

    img = models.ImageField(upload_to='photos/', max_length=254)
    text = models.CharField(max_length=254, blank=True)

class PhotoSerializer(serializers.ModelSerializer):

    class Meta:
        model = Photo
        fields = ('img','text')

意见：

class PhotoViewSet(viewsets.ModelViewSet):

    queryset = Photo.objects.all()
    serializer_class = PhotoSerializer

photo_router = DefaultRouter()
photo_router.register(r'photo', PhotoViewSet)

URL：

urlpatterns = [
    url(r'^admin/', admin.site.urls),
    url(r'^api/', include(photo_router.urls)),]

POST和GET在/api/photo/
中工作得很好我以前问过类似的问题，我肯定，问题是在前面，用AngularJS，我也是第一次使用AngularJS。但我现在想，可能是我的服务器应用程序出现了问题。
角代码：

var app = angular.module('myApp', ['ngRoute', 'angularFileUpload']);

app.config(function ($routeProvider) {

    $routeProvider
        .when('/', {
            templateUrl: 'http://127.0.0.1:8000/static/js/angular/templates/home.html'
    })
});
app.config(['$httpProvider', function($httpProvider) {
    $httpProvider.defaults.xsrfCookieName = 'csrftoken';
    $httpProvider.defaults.xsrfHeaderName = 'X-CSRFToken';
}]);

GET控制器工作良好，我累犯了我所有的图像：

app.controller('getController', ['$scope', '$http', function($scope, $http){
    $http.get('/api/photo/').success(function(data){
        $scope.photos = data;
    }).error(function(data) {
        $scope.photos = data;
    });
}]);

对于文件上传，我使用了本指南
，这里是指南中的代码：

app.directive('fileModel', ['$parse', function ($parse) {
return {
    restrict: 'A',
    link: function(scope, element, attrs) {
        var model = $parse(attrs.fileModel);
        var modelSetter = model.assign;

        element.bind('change', function(){
            scope.$apply(function(){
                modelSetter(scope, element[0].files[0]);
            });
        });
    }
};
}]);
app.service('fileUpload', ['$http', function ($http) {
    this.uploadFileToUrl = function(file, uploadUrl){
        var fd = new FormData();
        fd.append('file', file);
        $http.post(uploadUrl, fd, {
            transformRequest: angular.identity,
            headers: {'Content-Type': undefined}
        })
        .success(function(){
        })
        .error(function(){
        });
    }
}]);
app.controller('myCtrl', ['$scope', 'fileUpload', function($scope,     fileUpload){

    $scope.uploadFile = function(){
        var file = $scope.myFile;
        console.log('file is ' );
        console.dir(file);
        var uploadUrl = "/api/photo/";
        fileUpload.uploadFileToUrl(file, uploadUrl);
    };

}]);

html代码：

<div ng-controller = "myCtrl">
    <input type="file" file-model="myFile"/>
    <button ng-click="uploadFile()">upload me</button>
</div>

class PhotoViewSet(viewsets.ModelViewSet):  
    queryset = Photo.objects.all()
    serializer_class = PhotoSerializer

    def post(self, request, format=None):
        serializer = PhotoSerializer(data=request.DATA)
        if serializer.is_valid():
            serializer.save()
            return Response(serializer.data,  status=status.HTTP_201_CREATED)
        return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
