我在座各位反对隔离墙。 我想用<代码>f.select<>/code>标签做简单选择,但我没有做任何工作。 我举了一个例子:
<%= f.select(:object_field, [ Item 1 , Item 2 , Item 3 , Item 4 , Item 4 ], :class => my_style_class )%>
因此,奥基基本上只是一份简单清单,一旦提交表格,该表格就将价值列入<条码>目标_field<>。 并非所有工作,但从页面来源看,都不包括打字器。 它没有犯错,只是一刀切。
如果有人提出任何建议,我将非常赞赏。
采用这种方式:
<%= f.select(:object_field, [ Item 1 , ...], {}, { :class => my_style_class }) %>
http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#method-i-select
你们也可以增加这样的迅速选择。
<%= f.select(:object_field, [ Item 1 , Item 2 ], {include_blank: "Select something"}, { :class => my_style_class }) %>
我的工作
<%= f.select :status, [["Single", "single"], ["Married", "married"], ["Engaged", "engaged"], ["In a Relationship", "relationship"]], {}, {class: "form-control"} %>

选择标签最多可达到4名grument,最后一种grument是html办法,意味着你可以在此提出等级、要求和选择。
