simple_form 集合标签 [英] simple_form collection labels

问题描述

我想为收藏品使用标签(例如，它们的翻译).

I want to use labels for collection items (for example, their translations).

= simple_form_for(@client) do |f|
  = f.error_notification
    .form-inputs
      = f.input :name, label: t('client.name')
      = f.input :level, collection: ['a', 'b', 'c'],
        label_method: ????
        label: t('client.level')
    .form-actions
      = f.button :submit, value: t('client.submit')

我想弄清楚，上面的 label_method 使用什么.我想让 label_method 映射到翻译，如 map {|s|t("client.#{s}")}.

I am trying to figure out, what to use for label_method above. I would like to have label_method to map to translations as in map {|s| t("client.#{s}")}.

推荐答案

如果你还没有标签方法，你可以传递一个 lambda 来得到你想要的结果

If you don't already have a label method, you can pass a lambda to get the result you want

label_method: ->(obj){ t("client.#{obj}") }
