Django model_mommy 模型实例未保存在 Ajax 测试中

Question

我正在尝试测试保存字段的 django ajax 视图。这是测试：

def test_ajax_save_draft(self):
    self.client.force_login(self.test_user) # view requires login
    sub = mommy.make(QuestSubmission, quest=self.quest2)
    draft_comment = "Test draft comment"
    # Send some draft data via the ajax view, which should save it.
    ajax_data = {
        'comment': draft_comment,
        'submission_id': sub.id,
    }

    self.client.post(
        reverse('quests:ajax_save_draft'), 
        data=ajax_data,
        HTTP_X_REQUESTED_WITH='XMLHttpRequest',
    )

    self.assertEqual(draft_comment, sub.draft_text) # sub.draft_text = None, as if the ajax view was never called!

视图如下：

@login_required
def ajax_save_draft(request):
    if request.is_ajax() and request.POST:

        submission_comment = request.POST.get('comment')
        submission_id = request.POST.get('submission_id')

        sub = get_object_or_404(QuestSubmission, pk=submission_id)
        sub.draft_text = submission_comment
        sub.save()

        response_data = {}
        response_data['result'] = 'Draft saved'

        return HttpResponse(
            json.dumps(response_data),
            content_type="application/json"
        )

    else:
        raise Http404

当我运行测试时，我进入 if 块，它可以检索评论和提交对象，但是当它 returns 到最后的测试时，就像保存从未发生。

我做错了什么？

尝试调用 sub.refresh_from_db()

对模型实例所做的更改只会影响正在修改的实例。任何现有模型实例都不会更新，refresh_from_db 将从数据库中获取更改
