为什么 Rails 没有“errors.full_messages"?替换属性和消息变量? [英] Why doesn't Rails' "errors.full_messages" replace attribute and message variables?

问题描述

我刚刚创建的 Rails 模型有一个奇怪的问题.

Having a strange problem with a rails model I just created.

这是我的验证:

validates_presence_of :from_name, :message => 'Please provide a from name.'
validates_presence_of :from_email
validates_presence_of :giftition_plan_id

我在表单中使用 errors.full_messages 和 f.error_messages 时遇到问题:

I'm having issues using errors.full_messages as well as f.error_messages in my form:

g = Giftition.create
g.errors.first
=> ["from_name", "Please provide a from name."]
>> g.errors.full_messages
=> ["{{attribute}} {{message}}", "{{attribute}} {{message}}", "{{attribute}} {{message}}"]

我刚刚收到 "{{attribute}} {{message}}".有什么想法吗?

I'm just getting "{{attribute}} {{message}}". Any ideas?

更新:我已经卸载了 rails 3 和所有与它一起安装的 gem，这让问题消失了.但这不是解决办法……我仍然希望安装 rails 3.

UPDATE: I've uninstalled rails 3 and all the gems that were installed with it and that made the problem go away. It's not a fix though... I would still like to have rails 3 installed.

更新:听起来升级到 2.3.9 可以解决问题.不幸的是，我现在已经放弃了，但将来某个时候我会尝试的.

UPDATE: Sounds like upgrading to 2.3.9 fixes the problem. Unfortunately, I've given up for now, but sometime in the future I will try that.

推荐答案

升级到版本 rails 2.3.9 修复了这个问题

Upgrading to Version rails 2.3.9 fixes this problem

gem install -v 2.3.9 rails --include-dependencies

您还需要编辑 configenvironment.rb 文件以更改 RAILS_GEM_VERSION.

You also need to edit the configenvironment.rb file to change the RAILS_GEM_VERSION.

RAILS_GEM_VERSION = '2.3.9'

编辑#2:

请注意，2.3.9 版本不是 2.3.X 分支的最新版本，您应该升级可用的最新版本.

I should note that version 2.3.9 is not the latest version of the 2.3.X branch, and you should upgrade the the latest version available.
