Python 无法发布到DRF modelviewset-请求。数据立即清空

我在django模型前面设置了一个rest端点，这让我觉得是绝对最小的，但我不能从可浏览的API发布到它

在

djangorestframework==3.3.0

上，所有到

/api/transactions/

的帖子都被拒绝

提交表单会得到以下响应

HTTP 400 Bad Request
Content-Type: application/json
Vary: Accept
Allow: GET, POST, HEAD, OPTIONS

{
    "amount": [
        "This field is required."
    ],
    "description": [
        "This field is required."
    ]
}
