不同的Date_Select选择根据不同的选择：类别？

Question

用户有两个选项：“每月平均值”或“一次性实例”。在_form中选择一个是否有一种方法可以根据用户的选择使用javascript或其他东西调整_form中f.date_select的格式？

选择“每月平均值”后，我希望用户只能看到并选择：月份和年份。选择“一次性实例”后，我希望用户查看并选择：日，月，年。

_form.html.erb

<%= form_for(@quantified) do |f| %>
  <% if @quantified.errors.any? %>
    <div id="error_explanation">
      <h2><%= pluralize(@quantified.errors.count, "error") %> prohibited this quantified from being saved:</h2>

      <ul>
      <% @quantified.errors.full_messages.each do |message| %>
        <li><%= message %></li>
      <% end %>
      </ul>
    </div>
  <% end %>

<div class="america">
<form>
   <%= f.select :categories, Quantified::CATEGORIES %>

   <br>
   <br>

  <div class="form-group">
    <%= f.text_field :name, class: 'form-control', placeholder: 'Enter Name' %>
  </div>

  <div class="form-group">
    <%= f.text_field :result, class: 'form-control', placeholder: 'Enter Result' %>
  </div>

  <div class="form-group">
    <%= f.text_field :metric, class: 'form-control', placeholder: 'Enter Metric' %>
  </div>

    <div class="date-group">
      <label> Date: </label>
      <%= f.date_select :date, :order => [:month, :day, :year], class: 'date-select' %>
    </div>


<div class="america2">
  <%= button_tag(type: 'submit', class: "btn") do %>
  <span class="glyphicon glyphicon-plus"></span>
  <% end %>

  <%= link_to quantifieds_path, class: 'btn' do %>
  <span class="glyphicon glyphicon-chevron-left"></span>
  <% end %>

  <%= link_to @quantified, method: :delete, data: { confirm: 'Are you sure?' }, class: 'btn' do %>
  <span class="glyphicon glyphicon-trash"></span>
  <% end %>
</div>

</form>
</div>
<% end %>

quantified.rb

class Quantified < ActiveRecord::Base
	belongs_to :user
 	scope :averaged,  -> { where(categories: 'Monthly Average') }
  scope :instance, -> { where(categories: 'One-Time Instance') }

	CATEGORIES = ['Monthly Average', 'One-Time Instance']
end
