ruby-on-rails - rails date_select 类不会生效

Question

我有以下使用 date_select..

<%= f.date_select :birthday, :order => [:month, :day], :prompt => { :day => 'Select day', :month => 'Select month' }, :html => {:class => "select birthday"} %>

但是该类没有显示在 html 中..

<select id="profile_birthday_2i" name="profile[birthday(2i)]">
<select id="profile_birthday_3i" name="profile[birthday(3i)]">

我也试过了。。

<%= f.date_select :birthday, :order => [:month, :day], :prompt => { :day => 'Select day', :month => 'Select month' }, :class => "select birthday" %>

那也没有用。有任何想法吗？

Answer 1

HTML 选项是 date_select 的第四个参数。方法，而不是第三个参数中的键。

来自 documentation :

date_select(object_name, method, options = {}, html_options = {})

所以你会想要:

f.date_select :birthday, { :order => [:month, :day], :prompt => { :day => 'Select day', :month => 'Select month' } }, {:class => "select birthday"}
