Does ORM scale?
Just starting to look at the CF ORM stuff, pretty nice API, Hibernate underneath, all good. But as I understand it, ORM queries return arrays of cfc objects, and I'm concerned about performance at scale. On a gut level, I'd rather be able to get a native CF query, which I could deal with in straight CF as usual, or through an IBO if I wanted object-like behavior for that whole collection. So... - Is it possible to have CF ORM return a query, when I want it to? - What's people's experience with this stuff at scale, meaning large result sets, more than departmental traffic etc? Are there any largish sites doing that?

Re: Does ORM scale?
Not so much thinking about transactions, or avoiding straight queries with stored procs, more about returning large result sets as native queries rather than collections of cfc objects. One possibility of course is to use ORM for single/composite record detail, and native cf queries for search/list etc. That would be looking at result lists as a reporting function, where you'd use different (non-ORM) techniques. Really just wondering if people are using ORM at scale, if they're running into performance/memory issues, and how they're being dealt with if so.

Instantiating objects is nowhere near as much of a bottleneck as it used to be, so it depends on your application and requirements. It is a trade off at the end of the day, ORM increases productivity and reduces complexity but at the same time you lose flexibility and control and of course performance. If performance and scalability if your big concern for your database then you should perhaps be looking at using stored procedures, I don't know how hibernate copes with these, if at all but as the SQL and logic is in the SP, I can't see benefit to using ORM to call the SP anyway. -- Russ Michaels FREE CFML hosting for developers www.cfmldeveloper.com ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:338471 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Does ORM scale?
Thanks Joe, that's pretty much where I was headed too, with the possible/probable exception of using something IBO-like to leverage objects while iterating over a query. I grew up w SQL, never wanted something to just make it go away, but clearly life should be domain-object-centric, not db-centric. Still haven't heard from anyone actually in production with a large-scale ORM app yet. Maybe there just aren't any out there, around a year after CF 9.0. Or maybe they don't read this list, at least this quickly. We'll see...

If a service is working with changing data, use ORM. 2. If an operation largely works with one item (e.g. a form or detail page), use ORM. 3. If we're going to show a list of things, especially across tables, get off our butts and write a decent SELECT statement to return a query. The common argument against using a select/vanilla query is What it the getters in my objects model formatting/custom logic? Our response to that is to factor that logic into a helper class that is a) used by the object and b) used where the query is cfoutput'd. -Joe On Fri, Oct 22, 2010 at 8:44 AM, enigment enigm...@gmail.com wrote: Just starting to look at the CF ORM stuff, pretty nice API, Hibernate underneath, all good.

Using cfsetting showdebugoutput=false does actually disable debug output. Any chance there's another call to it somewhere else with a different setting?

Re: What version-/source control are you using (if any)?
At work we use AccuRev, which is expensive, and flawed, but on the whole really great. It has a stream inheritance model that means changes in an earlier release stream automatically flow to later releases unless there are changes to the same file there already. Also has integrated issue tracking, good change tracking, decent merging (I hear great things about the Mercurial and Git merge process, no experience so I can't compare).

Positional argument collection
Say I have an array of values, arbitrary length, that I want to pass
as the arguments to a method.
For example, with this:
positionalArgs = ['foo', 'bar', 42]; // this varies, may be any length
I want to make this call:
SomeComponent.someMethod('foo', 'bar', 42);
Is there a positional equivalent to argumentCollection, or some other
language construct that I don't know about to do this? If the
arguments were in a structure, I could pass it as the
argumentCollection, but I don't know how to do this by position in a
clean way.
Only thing I thought of is a switch statement with some finite number
of cases, each of which calls the method with a specific number of
arguments, like this (partial):
case 2:
SomeComponent.someMethod(positionalArgs[1], positionalArgs[2]);
break;
case 3:
SomeComponent.someMethod(positionalArgs[1], positionalArgs[2],
positionalArgs[3]);
break;
etc...
Any thoughts? Thanks,

argument, is very different than calling it once with all three. Say
they're search fields, lastName, FirstName, ZIP; you want the search
to run with all three of them in place, not separately for each one.

the array, but it doesn't matter, not what I need to do.)

That will call someMethod() for each array value. You could use a For loop

Missing the point. The method already exists and has other callers, who pass separate arguments by name or position. I'm not redesigning its API to take an array of arguments.

There are many more elegant approaches to your switch suggestion. The primary one being writing code that has structure and passes in the expected amount of arguments each time. Another one would be that since you know how many arguments you are expecting in the method perhaps write a function to loop over and pad your array with null values if they aren't defined. Then your call to the method can always pass in the expected amount of arguments.

Not to be cranky, but while there's room for debate on why I want to do this, this isn't that conversation. If there's no more elegant approach than the switch strategy I mentioned, I'll probably ditch this entire route. I first wanted to check if anyone could think of a way to accomplish this in the CFML language, out of curiosity and to maybe learn something that might be useful some day, as well to get it done -- there's lots of smart and experienced folks out there.

If it wasn't for that, you'd think the same about passing a structure of arguments -- any object you pass will be treated as a single argument. But argumentCollection trumps that. I even tried a structure with keys 1, 2, 3, and passing that as argumentCollection (unnamed arguments appear inside the function as 1, 2, and 3 if you dump arguments), no joy. @Jason: Clearly, calling a method three times, each time with one argument, is very different than calling it once with all three. Say they're search fields, lastName, FirstName, ZIP; you want the search to run with all three of them in place, not separately for each one. (Not sure why you went with an iterator rather than just indexing over the array, but it doesn't matter, not what I need to do.) Thanks for the ideas though. This just may not be possible.

Re: Positional argument collection
Hmmm, not sure what you mean by build a method call to the original method, and write the values positionally by iterating through the array. Do you mean write it out to disk or VFS? I'd thought of that, but wasn't super fond of the idea, since unless I'm missing something, you'd have to do that for every supported number of arguments for every publicly accessible method in the app. Or maybe I'm just not on your wavelength here.

How about writing a new method that takes two arguments: the name of the method you want it to call and an array of arguments. This method could then build a method call to the original method, and write the values positionally by iterating through the array. Presumably, you'd plop this method in a utility CFC, rather than in the original CFCs. Or, you could add it to the superclass so that it's present through your class hierarchy.

Re: Positional argument collection
You're right, I did misread your last post, sorry. But it's still not super practical as a generic SES-URL-to-method-call dispatcher, unless I'm still not getting what you mean. You'd need to inspect each method before you called it to find out how many args it takes, pad the array out that far, and then you'd still need a switch statement to call the method with that specific number of arguments. Keying the switch statement of the actual number of captured URL segments seems simpler and less overhead. In other words, whether the variable number of items in the array is the number of arguments for each individual method, or the number of URL segments actually captured, the problem of how to generically call a method with a variable number of arguments remains. Unless you want to find out the maximum number of arguments passed by *any* method, and always use that, but by that time I'd think this was too clunky to consider. Is there some other way you're thinking of to make the actual call? Dave On Wed, Oct 6, 2010 at 2:33 PM, Michael Grant mgr...@modus.bz wrote: Re-read my last post.

Re: Positional argument collection
No, actually not, unless I missed it. Evaluate is against my religion, but I might make an exception if there isn't any other way and I care enough. It's an odd language feature to work around, argumentCollection (args by name) exists, but there's no positional equivalent.

In this instance the application will always look in this location for files that it needs to process for the user. There's nothing built into HTML to capture a directory path. Also, browsers won't let you store a directory path for later use, for security reasons - the user always has to choose the file directly. Adobe AIR is a nice alternative here.

Re: 3 layers of validation?
IMO... - You *always* need server side validation, because as mentioned, client validation may not always run, and also so you can make an API available beyond browser front ends. - If that's true, I prefer to stay DRY and write validation in only one place, so that means on the server not the client. To work with that, you probably want to establish infrastructure and conventions to communicate server-side bus rule failures back to the client for presentation to the user. For example, our ajax layer includes the ability to specify mappings of back-end method arguments to a friendly name you can say to the user (Last name is required, not last_name), and a list of DOM IDs that should get highlighted in the UI if the data for that argument is invalid.
