我拼凑了一个快速而肮脏的应用程序来临时跟踪一些信息。我知道,不要以明文形式存储密码。这不是面向公众的,它在一个极其安全的内部盒子上;没有人可以访问它,该页面无法访问,只能访问一个简短的列表。无论如何...我试图弄清楚为什么当我编辑一条记录时,更新将一个尚未编辑的记录字段保存为空白,当它从具有值的数据库中读取时。在这种情况下,我从索引视图中选择一条记录。我编辑该记录,而不是触摸密码字段。我保存记录。从日志中可以看到,该字段为空白。
表格代码
<%= form_for(@swiftpwd) do |f| %>
<% if @swiftpwd.errors.any? %>
<div id="error_explanation">
<h2><%= pluralize(@swiftpwd.errors.count, "error") %> prohibited this swiftpwd from being saved:</h2>
<ul>
<% @swiftpwd.errors.full_messages.each do |msg| %>
<li><%= msg %></li>
<% end %>
</ul>
</div>
<% end %>
<div class="field">
Customer Name<br />
<%= f.text_field :customername %>

@anonymousxxx - 快速回答,是的,如果它已被编辑并删除。但就是这样,当我编辑时,该字段不是空白的,或者不应该是空白的。我在 index.html.erb 上屏蔽了用户的密码(我不呈现 swiftinfo.password 值,而只是显示“*****”。为了测试,我显示了密码值(swiftinfo.password)< %= swiftinfo.password %> 确实有密码。所以当我再次编辑该记录(或记录)时,密码有一个值。所以,如果我不编辑该字段,而是编辑另一个字段,或没有字段,更新应将当前值(已编辑或原始值)保存到表中。
更新:
好的,我已将问题隔离为:
<%= f.password_field :password %> - Browser displays blank, record is saved with a blank value
%= f.text_field :password %>
显示密码明文,但记录将正确的值(当前或更改)保存到表中。
