到位'id'想要放置一些链接是否可以在rails中
我正在尝试下面的代码没有得到，请帮帮我。

<%= select_tag "profile", options_from_collection_for_select(@profile, "profile/publications",'profile_blip'),:onchange => "window.location.replace('/'+this.value);" %>

Answer 1

options_from_collection_for_select创建一个这样的erb代码：

<option value="#{profile.id}">#{profile.profile_blip}</option>

在模型类中编写方法＆＃34; Profile＆＃34;返回你想要的东西。然后将select_tag更改为：

<%= select_tag "profile", options_from_collection_for_select(@profile, "new_method_name",'profile_blip'),:onchange => "window.location.replace('/'+this.value);" %>
