我正在尝试将其转换Application.cfc为脚本.原来有这个:
<cfcomponent displayname="Application" output="false">
<cfset this.name = "testing">
<cfset this.applicationTimeout = createTimeSpan(0,1,0,0)>
<cfset this.sessionManagement = true>
<cfset this.sessionTimeout = createTimeSpan(0,0,30,0)>
<cfsetting requesttimeout="20">
...

我无法弄清楚如何将cfsetting标签转换为脚本.以下尝试不起作用:
setting requesttimeout="20"; // throws a "function keyword is missing in FUNCTION declaration." error.
setting( requesttimeout="20" ); // throws a "Variable SETTING is undefined." error.

看起来Railo可能支持它(链接),但我找不到ColdFusion文档中cfsetting标签的等价物
如果可能,如何配置ColdFusion 9的ORM以使用多个DSN?
是否可以在会话范围的上下文中设置数据源而不是应用程序范围?
或者,在CF9中,您如何配置Hibernate以使用多个DSN?
看起来我应该更具体......我正在寻找一种允许根据会话指定DSN的解决方案.
这是场景.我们有一个自定义构建的应用程序,它使用多个DSN,这些DSN是从子域确定的.因此,从http://abc.domain.com访问的人将使用abc DSN,因为访问xyz.domain.com的人将使用xyz DSN.DSN的名称在创建会话时确定,并作为会话变量存储.
我想做这样的事情:
//Artists.cfc
component persistent="true" datasource="#session.dsn#"
{
property name="artistid" generator="increment";
property firstname;
property lastname;
property address;
property city;
property state;
}

// Application.cfc

THIS.applicationTimeout = createTimeSpan(0, 0, 0, 0);
THIS.clientManagement = false;
THIS.datasource = ""; // Leaving black ==> "No data source specified."
// Setting to cfbookclub ==> "ORM is not

// Setting to cfartgallery works but doesn't

你如何使用cfscript执行以下操作?
<cfmail
from="me@domain.com"
to="you@domain.com"
subject="Attachments">
<cfmailparam name="Reply-To" value="me@domain.com">
Some message goes here...
<cfmailparam file="c:\files\readme.txt">
<cfmailparam file="c:\files\logo.gif">

Run Code Online (Sandbox Code Playgroud) CFWheels具有URLFor()函数,用于根据提供的参数获取内部URL.有没有办法获得内部URL而不提供任何参数?
例如:如果用户导航到"http://somedomain.com"或"http://somedomain.com/about/"或"http://somedomain.com/contact/",则会出现类似ReWrittenURL的方法( )返回类似"/"或"/ about /"或"/ contact /"的内容?
使用不带参数的URLFor()会返回"/ home/index"或"/ about/index"或"/ contact/index".
CGI.SCRIPT_NAME返回"/rewrite.cfm"
显然使用Javascript使用document.location.href我可以得到我想要的东西.
我在尝试按照本教程操作时遇到了以下错误。奇怪的是,Google搜索此错误消息并没有带来任何有用的见解。
