如何重写测试设置中的一个值

Question

如何在测试设置中重写 'user': '5/分钟' on 'user': '2/day'

REST_FRAMEWORK = {
    'DEFAULT_THROTTLE_RATES': {
         'user': '5/minute'
    }
}

我如何使用@override_settings或带有上下文管理的mb来做到这一点？我只需要在一个测试中应用这个，我不能重写整个字典

def test_mytest(self):
    value = settings.REST_FRAMEWORK
    value['DEFAULT_THROTTLE_RATES'] = {'user':'2/day'}

    data1 = {}
    data2 = {}
    data3 = {}

with self.settings(REST_FRAMEWORK=value):
    resp1 = self.client.post(self.url, data1, format='json')
    resp2 = self.client.post(self.url, data1, format='json')
    resp3 = self.client.post(self.url, data1, format='json')

assert resp3.status_code == 429, resp3.data

但是没有429错误，虽然值已经改变了

    from unittest import mock

    @mock.patch('rest_framework.throttling.SimpleRateThrottle.get_rate')
    def test_api(self, get_rate):
        get_rate.return_value = '1/minute'

        from rest_framework.settings import api_settings
        print(api_settings.DEFAULT_THROTTLE_RATES)
        print(api_settings.user_settings)


        url = 'api'

        response = self.client.get(url)
        self.assertEqual(response.status_code, HTTP_200_OK)

        response = self.client.get(url)
        self.assertEqual(response.status_code, HTTP_429_TOO_MANY_REQUESTS)
