假设我有一个这样的模型类:

class Shoebox < ActiveRecord::Base
  validates_inclusion_of :description, :in => ["small", "medium"],
    :message => I18n.t("activerecord.errors.models.shoebox.with_name",
                     :name => name)
end

还有一些yaml:
en:
 activerecord:
  errors:
   models:
    shoebox:
     with_name: "the description of %{name} is not in the approved list"

我创建了一个新的鞋盒:
   s = Shoebox.new(:description => "large", :name => "Bob")
   s.valid?

但是当我查看错误(s.errors.first.message)时,我看到:



并不是:



我试过 :name => name:name => :name:name => lambda{name}:name => lambda{:name}

我试过创建一个辅助方法
 def shoebox_name
   name
 end

并传递 :name => shoebox_name:name => :shoebox_name:name => lambda{shoebox_name}:name => lambda {:shoebox_name}

如何将名称的 ivar 值插入到字符串中?

最佳答案

尝试删除验证中的消息选项,并将您的 yaml 更改为:

en:
 activerecord:
  errors:
   models:
    shoebox:
     description:
       inclusion: "the description of %{name} is not in the approved list"
