javascript - Ruby Rails - 为 AJAX 调用 Controller 操作构建数据

Question

我的网站上需要一个按钮，可以将信息发送到 Controller 的创建操作(“pagetimes”)。它似乎有效，尽管它没有发送我指定的所有数据——可能与我无法构建数据向量有关。我已通过 post 'pagetimes/create'

在我的 config/routes.rb 文件中提供 POST 请求

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)，并且可以访问在模型中，并且可在新页面时间的手动输入"new"页面中显示的内容中使用。

在我的页面 View 中:

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

其他一切都非常标准。我可以在我的数据库中看到该帖子已成功提交，但我尝试填充的 3 个数据字段均为 NULL。这可能与我构建 data: {} 字段的方式有关？

O/w，Win7 上的 Rails 3，不使用任何可能对此有影响的其他花哨的东西......

更新1:这就是我试图发布的表单源代码的样子。也许是我错误地引用了字段？

<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:这是我的日志中包含 POST 的部分:

更新 3: Controller 操作

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

Answer 1

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