Question

我是rails的新手，今天我使用验证创建了我的第一个Web应用程序，我只是将这些行放入模型中：

class ClientWorkout < ActiveRecord::Base

  validates_numericality_of :paid_amount
  validates_presence_of :client_name

end

这是视图部分：

<% form_for(@client_workout) do |f| %>
  <%= f.error_messages %>
      etc etc

一切正常，价值存储在数据库中，成功案例＆lt;如果出现错误，则会以下面这种奇怪的方式在视图上显示此错误：

{{count}} errors prohibited this {{model}} from being saved

There were problems with the following fields:
{{attribute}} {{message}}
{{attribute}} {{message}}

（示例显示当表单的2个参数错误时发生了什么，但这种情况在每种情况下都会发生）
它不会设法用真实价值取代“计数，模型，属性和信息”。任何人都可以弄清楚发生了什么？我使用Ror 2.3.8和rails 1.8.7

Answer 1

Rails在2.3中引入了内置国际化。你的问题是一些已知的错误，有一些rails和i18n gem的组合。如果你有i18n gem版本0.5.0，请尝试降级到0.4.2。如果你正在使用系统宝石：

sudo gem uninstall i18n
sudo gem install i18n -v 0.4.2

如果您使用RVM管理宝石，则不需要sudo命令。

Answer 2

如果您对更改i18n版本不感兴趣，可以执行以下操作在config/locales/en.ym

中添加以下代码

如果en:已经可以从ActiveRecord复制并粘贴

之后停止服务器并再次启动，应正确显示错误消息...
