替换 'collection_select, :multiple =>真"，在 Rails 中有多个“check_box"选项 [英] Replace 'collection_select, :multiple => true' with multiple 'check_box' options in Rails

问题描述

如何用 check_box 选项列表替换 collection_select(使用 :multiple => true)，这样就有集合中每个对象的 check_box 选项?

How do you replace a collection_select (with :multiple => true) with a list of check_box options, such that there is a check_box option for each object in the collection?

是否有一种优雅的方式来使用表单构建器(即不使用 *_tag 助手)来实现这一点?我想尽可能多地依赖 ActiveRecord 的内置功能...

Is there an elegant way to implement this using form builders (i.e. without using *_tag helpers)? I'd like to lean on ActiveRecord's built in functionality as much as possible...

推荐答案

我不认为有一种内置的优雅"方式可以做到这一点.

I don't think there's a built-in "elegant" way to do this.

这个 railscast 应该能让你继续前进:
