Ruby on rails money rails gem不允许我在文本框中输入美分

我在使用money rails gem将值保存到数据库时遇到问题。每当我尝试在文本框（即20.22）中输入一个带美分的值时，就会出现一个错误，提示“请输入一个有效值。两个最接近的值是20和21。”

型号：

class VideoGame < ActiveRecord::Base

    monetize :loose_price_cents, with_model_currency: :price_currency
    monetize :cib_price_cents, with_model_currency: :price_currency
    monetize :new_price_cents, with_model_currency: :price_currency

end

我已经进入rails控制台并手动更改了周围的值，但它似乎以数据库值（db value=2011美分，error=“请输入一个有效值。两个最接近的值是20.11和21.11。”）作为错误的基础

任何建议都将不胜感激

编辑： 我想出来了。通过将“步骤：0.01”添加到数字_字段方法的末尾，您可以将值增加0.01，而不是默认情况下的1。它应该是这样的：

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

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

  <div class="field">
    <%= f.label :game %><br>
    <%= f.text_field :game %>
  </div>
  <div class="field">
    <%= f.label :loose_price %><br>
    <%= f.number_field :loose_price, step: 0.01 %>
  </div>
  <div class="field">
    <%= f.label :cib_price %><br>
    <%= f.number_field :cib_price, step: 0.01 %>
  </div>
  <div class="field">
    <%= f.label :new_price %><br>
    <%= f.number_field :new_price, step: 0.01 %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>

禁止保存此视频游戏：

def update
      respond_to do |format|
      if @video_game.update(video_game_params)
        format.html { redirect_to @video_game, notice: 'Video game was successfully updated.' }
        format.json { render :show, status: :ok, location: @video_game }
      else
        format.html { render :edit }
        format.json { render json: @video_game.errors, status: :unprocessable_entity }
      end
    end
  end

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

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

  <div class="field">
    <%= f.label :game %><br>
    <%= f.text_field :game %>
  </div>
  <div class="field">
    <%= f.label :loose_price %><br>
    <%= f.number_field :loose_price, step: 0.01 %>
  </div>
  <div class="field">
    <%= f.label :cib_price %><br>
    <%= f.number_field :cib_price, step: 0.01 %>
  </div>
  <div class="field">
    <%= f.label :new_price %><br>
    <%= f.number_field :new_price, step: 0.01 %>
  </div>
  <div class="actions">
    <%= f.submit %>
  </div>
<% end %>
