Thanks Matt and Peter for that extra info. It is always great to find out
what other programmers are doing in their CFCs.
Peter, when using argument collection, does it pass named-value pairs to the
method?

I always cringe when I see By or From in a method name.
For me, it looks like it could be a duplication of code.
If you have some getProducts logic, you want to be careful not to
duplicate that logic in multiple methods.
If your getProductsByCat and getProductsByFormat methods are both

Hi Aaron,
You pass in a struct and it matches the names of the keys within the struct
to the names of the arguments to the method. So

I always cringe when I see By or From in a method name.
For me, it looks like
I'm pretty sure you can do this:
cfset getProductsAndItems =
productItemGateway.getProductAndItems(arg1=#url.formatID#,
arg2=#url.catID#) /
...where arg1 and arg2 are whatever the cfargument name=arg1 value
is.
Does that make sense? My syntax might be slightly off, but it's
something pretty
Is it possible to specify which argument you are passing into
a method when creating an object? When I use the following
syntax, the method assigns the first parameter to the first
argument, the second parameter to the second argument and so on:
cfset productItemGateway =
Yeah, that makes sense. Let me give it a try and get back to you to
see if the syntax is correct.
In the meantime, I am wondering if this is even a good idea. It seems
to me like it kind of violates the principles of encapsulation and
data hiding. What do you think?

There's nothing wrong with using named notation. To call a function, you
need to know something about the data it expects
You can specify name-value pairs (named notation) in any order; the
default notation where you specify the values in order is called positional
notation.
Dave, could you give me an example of the syntax for name-value pairs?
Thanks,
Aaron
Nolan,
your syntax worked just fine. I am wondering if there is some other
way that Dave might be getting at. Also, I am still wondering if I
should even take this approach since one would have to know the exact
spelling of the arguments in the method.

Example of name/value pairs:
Say you have a method like this:
cffunction name=getFoo
cfargument name=age
cfargument name=gender
.
/cffunction
Using name/value method calling you can do this:
cfset bar = getFoo(age=26, gender=M)
-OR-
cfset bar = getFoo(gender=M,

In my gateway I have a method which accepts two arguments. The query
selects products by category (if catID NEQ 0) or by format (if
formatID NEQ 0). I originally had two methods, but I thought that with
a little conditional logic I could make one method. My thinking was
better code reuse, but

Thanks a lot everyone!
A week ago I was tearing my hair out trying to figure all this OOP and
CFC stuff out but I decided to just seperate my model into beans, DAOs
and gateways (leaving off services and facades for now) and I'm
finally writing some code again and it seems to be coming together.
Hi all,is it correct Aaron's component invocation?cfset productItemGateway = createObject(component,productItemGateway).init(Application.dsn)cfset getProductsAndItems =
productItemGateway.getProductAndItems(url.formatID,url.catID) /Looks like every time CF will instantiate that cfc right? Marco

break your code accidentally when refactoring your db schema.

Hey Peter, several of my cases have 4-5 search fields available to the user (Customer ID #, First name, last name, company name, city, ...). So I find the Uber Search function easier to use because in it I can test for values in each of these fields and include an AND FirstName LIKE

also a great solution for dynamic code where you want to call different methods

You're
