Ruby Rails-为AJAX调用控制器动作构造数据

我的网站上需要一个按钮，可以将信息发送到控制器的create动作（“ pagetimes”）。尽管它没有发送我指定的所有数据，但似乎仍在工作-
可能与我无法构造数据向量有关。我已经通过以下方式在config / routes.rb文件中提供了POST请求：post 'pagetimes/create'

在application.js中：

function submitForm() {
  alert("checked the button - worked");
  $.ajax({
    type:'POST',url: '/pagetimes/create',data: { pagename: "whatever",start: 7,end: 21 },});
}

其中:pagename，:start和:end是我的数据表中的列（字符串，整数，整数），并且可以在模型中访问，并且可以在手动输入“新”页面中显示的页面时间获得。

在我的页面视图中：

<button type="button" onclick="submitForm()">Send data</button>

其他一切都是很标准的。我可以在数据库中看到该帖子已成功提交，但是我尝试填充的3个数据字段均为NULL。可能这与我如何构建该data: {}领域有关？

O / w，Win7上的Rails 3，没有使用其他可能与此有关的花哨内容&Hellip;

更新1：这就是我尝试发布的表单源代码。也许是我不正确地引用字段的情况？

<div class="form-inputs">
  <div class="control-group String optional pagetime_pagename"><label class="String optional control-label" for="pagetime_pagename">Pagename</label><div class="controls"><input class="String optional" id="pagetime_pagename" name="pagetime[pagename]" size="50" type="text" /></div></div>
  <div class="control-group Integer optional pagetime_start"><label class="Integer optional control-label" for="pagetime_start">Start</label><div class="controls"><input class="numeric Integer optional" id="pagetime_start" name="pagetime[start]" step="1" type="number" /></div></div>
  <div class="control-group Integer optional pagetime_end"><label class="Integer optional control-label" for="pagetime_end">End</label><div class="controls"><input class="numeric Integer optional" id="pagetime_end" name="pagetime[end]" step="1" type="number" /></div></div>
</div>

更新2：这是我的日志，其中包含POST：

更新3：控制器动作

def create
  @pagetime = Pagetime.new(params[:pagetime])
  @pagetime.user = current_user

  respond_to do |format|
    if @pagetime.save
      format.html { redirect_to @pagetime,notice: 'Pagetime was successfully created.' }
      format.json { render json: @pagetime,status: :created,LOCATIOn: @pagetime }
    else
      format.html { render action: "new" }
      format.json { render json: @pagetime.errors,status: :unprocessable_entity }
    end
  end
end
