为什么我的模型不能在我的Rails API中更新？

Question

我正在Rails中开发一个API，并从另一个Rails应用程序与它进行交互。到目前为止，一切都正常工作，使用POST和GET来验证用户、创建记录和检索数据。但是现在我在获取PUT操作来更新记录时遇到了问题。它似乎正确地调用了API，并且API返回了200响应，但从日志来看，Rails甚至不像是在执行UPDATE语句。最奇怪的是没有错误或警告。

这是日志。(数据是伪造的数据，所以我不会费心去修改它)

Started PUT "/affiliates/17" for ::1 at 2019-04-26 17:42:51 -0400

您可以在日志中看到参数数据。控制器的动作非常简单：

# PATCH/PUT /affiliates/1
  def update
    if @affiliate.update(affiliate_params)
      render json: @affiliate
    else
      render json: @affiliate.errors, status: :unprocessable_entity
    end
  end

提前感谢您的帮助。

事实证明，无论出于什么原因，put方法都要求我识别标头中的内容类型。Post没有这样做，但更改了我的HttParty调用中的行，解决了这个问题：

response = HTTParty.put(put_uri, body: @this_data.to_json, headers: { 'Content-Type' => 'application/json', 'Authorization' => @token })
