Insert some value into a result of a find in a db.

Hi, I'm trying to insert a string component into what was found by a find search. E.g. do a @version = Version.find("270") @path = "somestring" And I would like to stick the @path string into @version then later do a render :xml => @version in order to produce <versions>     <version>         <id>"270"</id>         .         .         .         <path>"somestring"</path>     </version>     <version/> </versions>

Is this possible? The value of @path is not necessarily a result from a search in the db so I can't combine two searches via something like a find_by_sql or include.

Should be no problem. You can add an attribute to @version and it will be emitted when you render.

Try it in the console.

@version = Version.find(...) @version['path'] = 'somestring' @version.to_xml

Hey that's great! Simple and sweet. Can I set the type? As it stands it's coming out as type=\"NilClass\" On the flip side, can I also remove the type info? thanks
