问题标签 [vestal-versions]

我对在 Rails 3 中使用 Vestal 版本非常感兴趣。有谁知道 Rails 3 是否适用于 Vestal 版本？我听说一些用户遇到了问题：

ActiveRecord::DangerousAttributeError: changes is defined by ActiveRecord" 它使用模型中称为更改的字段。不确定是否有计划修复该问题。

但我猜有人已经找到了解决办法。愿意分享吗？

谢谢

我在这里使用 Vestal 版本叉来支持 Rails 3：http: //github.com/adamcooper/vestal_versions/

我遇到的问题是 updated_by => current_user 在更新时没有存储在版本表中。

我检查了日志，没有错误，Rails 在数据库中为用户字段插入空值，我需要填充的是 user_id

想法？

谢谢

我期待它是 2 个版本之间所有更改的结合。（使用 Vestal 版本 1.0.2）

如您所见，8 和 12 之间没有变化，但其中一些之间发生了变化。

奇怪的是我发誓这是昨天的工作！

这是vestal使用的方法，我不确定问题是什么：

我现在设置它以将图像保存到我的 rails 文件系统并将文件的旧版本保存在 /images/:id/:version/:filename 之类的路径中

如何使用 vestal_versions 获取旧文件路径的 url？

使用 .revert_to!(1) 会增加实际的版本号，因此 @image.version 的 2 然后恢复为 1，变为版本 3，这完全让我无法获取旧文件的 url。

使用 reset_to 会删除所有以后的修订。

我该怎么做呢？你需要澄清吗？

我正在使用 Rails 3 Vestal 版本 gem：https ://github.com/lailsonbm/vestal_versions

我想创建一些逻辑来确定是否/何时在模型更新上创建新版本。根据规格，我做了：

但这不起作用，我收到以下错误：

有什么建议或想法吗？谢谢

更新

有条件的版本创建。版本化方法现在接受 :if 和 :unless 选项。每个都需要一个表示实例方法或过程的符号，该符号将被评估以确定是否在更新后创建新版本。也可以给出包含符号和 procs 的任意组合的数组。class User < ActiveRecord::Base versioned :if => :really_create_a_version? 结尾

我正在观看 railscasts 第 177 集，因为我需要在我的应用程序中实现一些版本控制。但是这一集并没有在 Rails 3 中完成。所以我去了 gem 本身的站点。

https://github.com/laserlemon/vestal_versions

现在，它说它已经用 Rails 3 进行了测试，但即使将该行放在 gemfile 中也不允许我安装它。我刚刚使用 gem install 等安装。

现在甚至生成迁移都是一个问题，因为我得到了错误

有没有人成功使用可以给我建议的宝石？

非常感谢！

我正在尝试将vestal_versions (1.2.2) 添加到使用globalize3 (0.0.11) 进行模型本地化的站点。

当我尝试像这样显示模型的版本时：

我得到：

查看器中的类型错误#show

显示 /home/florian/spzwww3/app/views/viewer/show.html.erb 其中第 50 行提出：

无法访问条件

第 50 行是与@page.version

在控制台中显示版本工作正常：

任何想法“无法访问条件”条件意味着什么？

我以前从未见过这条消息，谷歌只返回一个与该短语无关的结果。

提前感谢您的任何提示。

这是完整的跟踪：

我收到此错误，我不知道如何调试它。它似乎出现在我的控制器的创建操作中的“保存”方法中：

我想我在部署vestal_versions 时开始遇到问题：

如何将带有原始版本的 user_id、user_name、user_type 插入到版本表中？

我们计划在我们的 Rails3 应用程序中启用一些表审计。我们确实查看了 paper_trail ，它似乎存储了所有版本，但我不确定是否有一种机制可以发现连续版本中字段更改的区别。是否可以使用 paper_trail gem 或者我应该使用类似 vestal_versions 的东西来实现此功能？
