我们希望在表单中添加一个新的隐藏字段，但是每次我添加一个新字段时（甚至复制并粘贴一个有效的字段并在末尾添加一个数字），我们都会收到错误消息，
ActionView::Template::Error (undefined method `hidden_gclid' for #<Wizard::Lead::Step2:0x00000004d859d8>):
请让我知道您想查看哪个代码。我尝试阅读一些文档here，并认为可能需要添加数据库列，但不确定。
感谢大家的帮助，对于造成的延迟，我深表歉意。我没收到 通知通知。我有一个新问题。创建新字段后，我们会收到此错误，

看起来我们的表单现在没有任何错误，但是我们需要将隐藏字段ID 00N1N00000PMKAo发送给salesforce，但不是。
答案 0 :(得分：0)
由于simple_form依赖于模型实例，因此这里有两个选择：
看起来您不想将值存储在数据库中，在这种情况下，只需将attr_accessor :hidden_gclid添加到模型中即可。之后，您可以像在控制器操作中的普通属性一样使用它。
