Rails选项选择：类未应用？

Question

请告诉我应该如何修复此选项/选择菜单。我糟糕的语法必须阻止:class =>"sign-pay-lm1"被应用。

<span class="signup-label-paying">
  <%= select "payments", "expiry_month", User::MONTH_NAMES.collect{|x| [x, User::MONTH_NAMES.index(x) + 1] }, :class =>"sign-pay-lm1" %>
</span>

Answer 1

尝试：

<span class="signup-label-paying"><%= select "payments", "expiry_month", User::MONTH_NAMES.collect{|x| [x, User::MONTH_NAMES.index(x) + 1] }, {}, { :class =>"sign-pay-lm1"} %>

确实html_options是最后一个哈希。 See doc
