Question

以下字段 1.Name 2.gender 3.price 4.email 5.payment

全部存储在数据库中。但是购买日期不存储在数据库中。所有字段都显示在编辑用户表单中，但不显示购买日期。

_form.html.erb

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

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

**购买日期**

<div class="col-md-8">
   <%= f.label :purchasedate %><br />
   <%= f.text_field :purchasedate ,:value => @purchasedate %>
![enter image description here][1] </div>

我想将购买日期存储在数据库中，并且它的值显示在“编辑用户”表单中。请帮帮我。

Answer 1

<%= f.text_field :purchasedate ,:value => @purchasedate %>

使用:value => @user.purchasedate代替:value => @purchasedate

我想在编辑表单的日期字段中选择购买
