问题描述
我正在使用引导CCS设置我的Rails 4应用程序的样式，但是在使用form_for辅助程序时无法弄清楚如何向表单添加类.我没有在其他几个线程上遵循建议.两个这样的线程...
I'm using bootstrap CCS to style my Rails 4 app, but cannot figure out how to add a class to the form when using the form_for helper. I have followed the suggestions on several other threads without success. Two such threads...
- How do you override the class name in the form_for helper?
- adding (not overwriting a class) for a form generated by the form_for helper
该应用程序按照说明应能正常工作，但我也希望它看起来也不错.这是工作代码，并注释掉了第一行，因为它没有按我的需要向表单中添加其他类.
The app works as it should per the instructions, but I want it to look good too. Here is the working code and have commented out the first line as it does not add the additional class to the form as I need it to.
有人可以帮助解决这一挑战吗?希望今天有一些聪明的Rails开发人员可以为您提供帮助.

form_for，其类名称为haml:
form_for with class name in haml:
= form_for @patient, :html => {:class => "form-horizontal"} do |f|
它也可以写为
= form_for @patient, {:html => {:class => "form-horizontal"}} do |f|
但是不能写成
- form_for @patient, :html => {:class => "form-horizontal"} do |f| #it gives error.
