【问题描述】：

我有以下型号：

class AccountMovement < ActiveRecord::Base
  has_one :accounting_document
  ..
end

class AccountingDocument < ActiveRecord::Base
  belongs_to :account_movement
  ..
end

class CreditNote < AccountingDocument
  ..
end

class Invoice < AccountingDocument
  ..
end

用户可以添加信用票据

<%= form_with model: @credit |f| %>

  <%= f.fields_for :account_movement do |ff| %>
    <div>
      <%= ff.label :amount %>
      <%= ff.number_field(:amount, step: 0.01, autofocus: true) %>
    </div>
    ...
  <% end %>
  ...
<% end %>

网站只支持葡萄牙语，所以我添加了以下翻译

pt:
  activerecord:
    attributes:
      account_movement:
        amount: 'Valor'

但它无法自动翻译 account_movement 的金额属性。当表单看起来像这样时，这适用于 has_one 关系

<%= form_with model: @account_movement |f| %>

  <div>
    <%= f.label :amount %>
    <%= f.number_field(:amount, step: 0.01, autofocus: true) %>
  </div>

  <%= f.fields_for :credit_note do |ff| %>
    ...
  <% end %>

  ...
<% end %>

我已经尝试了很多方法都没有成功

pt:
  activerecord:
    attributes:
      account_movement:
        amount: 'Valor'
      credit_note/account_movement:
        amount: 'Valor'
      credit_note[account_movement]:
        amount: 'Valor'
      credit_note_account_movement:
        amount: 'Valor'

我是否遗漏了某些内容或不支持在 fields_for 中自动翻译反向 has_onde 关系？

【解决方案1】：

我发现了问题。它在AccoutingDocument 处缺少accepts_nested_attributes_for :account_movement

class AccountingDocument < ActiveRecord::Base
  belongs_to :account_movement

  accepts_nested_attributes_for :account_movement
  ..
end

不需要在本地添加额外的翻译

pt:
  activerecord:
    attributes:
      account_movement:
        amount: 'Valor'
