包含数据库主键的表单中的下拉菜单

In a framework like Django or Pylons you can set up function to handle form submissions. If your form involves a dropdown menu (i.e. a select tag) populated with objects from a database you can set the values equal to the primary key for the record like:

在像Django或Pylons这样的框架中,您可以设置函数来处理表单提交。如果您的表单涉及使用数据库中的对象填充的下拉菜单(即选择标记),则可以将值设置为等于记录的主键,如:

<select>
  <option value="1">Volvo</option>
  <option value="2">Saab</option>
  <option value="3">Mercedes</option>
  <option value="4">Audi</option>
</select>

Is this a safe practice? Is there anything wrong with using a primary key? If you were not to use the primary key for the value how else can you make this form?

这是安全的做法吗?使用主键有什么问题吗?如果您不使用主键作为值,您还可以制作此表单吗?

Using the primary key is fine. What exactly are you concerned with? This is an implementation detail that won't show up to the user in the actual rendered page.

使用主键很好。你究竟在关注什么?这是一个实现细节,不会在实际呈现的页面中显示给用户。
