Question

我有以下date_select助手。我想添加一个类，但它不生成HTML。

<%= date_select :recipient, :birthday, :order => [:day, :month, :year], :start_year => 1920, :end_year => 2013, :class => "input-mini" %>

我也尝试过使用哈希，因为有些解决方案建议但我得到语法错误：

<%= date_select :recipient, :birthday, :order => [:day, :month, :year], :start_year => 1920, :end_year => 2013, {:class => "input-mini"} %>

不确定我是否真的了解何时以及如何使用哈希格式化它。

Answer 1

经验证的答案对我不起作用，有效的是：

<%= date_select
    :recipient,
    :birthday,
    {:order => [:day, :month, :year], :start_year => 1920, :end_year => 2013},
    {:class => "input-mini"}
%>

根据docs：

更有意义

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

Answer 2

这应该有效：

<%= date_select :recipient, :birthday, 
:order => [:day, :month, :year], 
:start_year => 1920, 
:end_year => 2013, 
:html=>{:class => "input-mini"} 
%>

更新：适用于Rails 5

<%= date_select :recipient, :birthday, 
               {
                :order => [:day, :month, :year], 
                :start_year => 1920, 
                :end_year => 2013
               }, 
               {:class => "input-mini"}  %>

Answer 3

试

在像:html=>{:class=>'input-mini'}

这样的html哈希中进行分类

<%= date_select :recipient, :birthday, :order => [:day, :month, :year], :start_year => 1920, :end_year => 2013, :html=>{:class => "input-mini"} %>

Answer 4

正如我们在docs上看到的那样，date_select帮助器需要特定的参数：

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

对我来说，不要添加方法选项，并将选项hash {}空置完美：

datetime_select(:recipient, {}, {:class => 'custom-select'})

或者，如果您想使用:birthday param，您只需使用：

datetime_select(:recipient, :birthday, {}, {:class => 'custom-select'})

将一个CSS类添加到date_select
