在Rails中将一个Bootstrap类应用于form_for

Question

我试图应用bootstrap类＆＃34; form-horizo​​ntal center＆＃34;我的rails form_for帮助如下：

<%= form_for(@customer), :html => {:class => "form-horizontal center"} do |f| %>

我收到语法错误。

我没有运气看过这个：How to add a class to the form_for helper in a Rails 4 app?

有什么想法吗？

Answer 1

<%= form_for @customer, :html => {:class => "form-horizontal center"} do |f| %>

从@customer移除括号或在do之前移动右括号：

<%= form_for(@customer, :html => {:class => "form-horizontal center"}) do |f| %>
