如何本地化表单对象上的错误消息

Question

Rails 7 中是否可以本地化表单对象中的属性，包括

ActiveModel::Model

？

我有以下内容

class  ProductionDataForm
  include ActiveModel::Model

  attr_accessor :monitorable_type

  validates :monitorable_type,  presence: true
end

当

monitorable_type

丢失时，我想显示

Post can't be blank

而不是

Monitorable type can't be blank

。

因此，正如我对继承自

ApplicationRecord

的对象所做的那样，我尝试定义

en:
  activerecord:
    attributes:
      production_data_form:
        monitorable_type: "post"

但是不起作用。

Answer 1

class ProductionDataForm
  include ActiveModel::Model
  include ActiveModel::Attributes
  attribute :monitorable_type, :string # ?
  validates :monitorable_type, presence: true
end

en:
  activemodel:
    attributes:
      production_data_form:
        monitorable_type: "post"
