在flask-restless中PATCH_MANY预处理器中的search_params为空

Question

我通过PUT发出以下HTTP请求:

http://example.com/api/student?q=%7B%22filters%22:%5B%7B%22name%22:%22id%22,%22op%22:%22%3D%3D%22,%22val%22:1%7D%5D,%22disjunction%22:true%7D

，其中查询字符串解码为:

q:{"filters":[{"name":"id","op":"==","val":1}],"disjunction":true}

在我的flask-restless代码中，我用这些选项创建端点:

    {
        'model': Student,
        'methods': ['GET', 'PUT', 'PATCH', 'POST', 'DELETE'],
        'preprocessors': {
            'POST': [pre_post_student],
            'PATCH_MANY': [pre_patch_many_student]
        },
        'allow_patch_many': True
    },

然后我定义了一个预处理器函数:

def pre_patch_many_student(search_params=None, data=None, **kw):
    # Handle group management for the given students
    print search_params

但是，当为上面的请求调用该函数时，search_params出现为空字典。

为什么?

打补丁时，flask-restless不会在url中查找参数，而是在请求体中查找参数。因此body应该是:

{"q":{<filters and rules>},"field_to_edit":"content",...}

这可能已经太晚了，但无论如何。
