对于传统的MySQL 5.1数据库,哪个ORM最适合使用新的Rails 3应用程序?我不希望对这个数据库进行迁移(尽管模式可能会不时发生变化),但我一定会写信给它.
我试图在一台机器上找到一个奇怪行为的底部.我有一个简单的控制台应用程序,它将以交互方式运行,但是当我通过WMI调用它时,它将立即启动并退出.
我启用了Fusion日志,因为Procmon没有发布.我看到以下错误:
*** Assembly Binder Log Entry (31-01-2015 @ 19:22:51) ***

"功能不正常"的原因是什么?我还能看到什么来确定此应用程序通过WMI在启动时有效死亡的原因?
我的意思是微不足道的 ......

我的UsersControllerTest当前失败,因为我在UsersController #create中使用verify_recaptcha.如何编写我的测试,以便使用params [:user]传递已知良好的CAPTCHA响应?我正在使用reCAPTCHA,但我想这个问题适用于任何CAPTCHA实现.
这是我的UsersController #create

@user = User.new(params[:user])
if verify_recaptcha(@user) && @user.save
flash[:notice] = "Account registered!"
redirect_to new_order_url
else
flash.now[:error] = "Account not registered!"

有些情况下我必须在运行时动态更改此查询,因此我执行以下操作:
SqlDataSource1.SelectCommand = sql; // 'sql' is the new query
GridView1.PageIndex = 0;
GridView1.EditIndex = -1;
GridView1.SelectedIndex = -1;
GridView1.DataBind();
updatePanel.Update();

实际上这很好用,但是当我单击分页控件时,结果集默认返回到中SelectCommand定义的SqlDataSource1.
有什么方法吗?

我有一个使用表单身份验证的ASP.NET应用程序,并将凭据存储在表中 - 非常香草.既然我知道如何对密码进行哈希处理,我可以以某种方式与Rails共享表单auth cookie,从而有效地创建单点登录吗?这两个网络应用都将位于同一个域中.

我使用 aFileSystemWatcher来通知文件更改,然后创建该文件的副本:
$watcher = New-Object System.IO.FileSystemWatcher
$watcher.Path = "C:\Orders\"
$watcher.IncludeSubdirectories = $false
$watcher.EnableRaisingEvents = $true
$changed = Register-ObjectEvent $watcher "Changed" -Action {
write-host "Changed: $($eventArgs.FullPath)"
$datestamp = get-date -uformat "%Y%m%d%H%M%S"
write-host $datestamp
copy-item $eventArgs.FullPath "$(watcher.Path)backup-$datestamp"
}

因此,如果C:\Orders\orders.xml发生更改,则C:\Orders\backup-20131125121004应该创建。但是,这不起作用,并且不会产生错误。通知确实有效,只是副本不起作用:

我正在使用Devise进行身份验证,因此我在遗留数据库中使用了几列别名来适应它,如下所示:
class User < ActiveRecord::Base
set_table_name 'my_legacy_user_table'
set_primary_key 'UserId'

alias_attribute :username, :LoginId
alias_attribute :encrypted_password, :PasswordSHA1Hash

alias_attribute :last_name, :Surname
