So you're calling  this file from within ColdFusion directly right?

What happens if you create it using CreateObject?

cfset myCFC = CreateObject('component','cfc.filename') 
cfset user = myCFC.Read(13204721-3474-8967-4897498740174013)

Are you getting an error?

directly off the web root where I'm calling this).

The read function shows the following..

       cffunction name=Read returntype=Query access=remote
               cfargument name=UserID type=string
               cfscriptvar Data=;/cfscript
               cfquery DATASOURCE=#DS# name=Data
                       Select *
                       From Users
                       Where UserID=#UserID#
               /cfquery
               cfreturn Data
       /cffunction

Why isn't it working?

Hey Philip,

Nothing else?


If so, then, it's working... You just don't have any code to display the
result.

Add this

cfdump var=#User#


And remove those numbers from between the invoke tag, just to be safe.

Re: CFC Question


That is litterally all the code in the page. It isn't firing the invoke.

But I have good news. I have been working with fusebox on this (having
double cfc's inthe circuit directory and the root just to be sure) and
it wasn't working.

I moved it over to it's own folder with no fusebox and I'm getting
errors now. So at least I can track it down.

Thanks to all who helped. I didn't think Fusebox would remove the
error messages.

Putting CFCs in the App scope is perfectly acceptable. You just have to know
that's where they're stored. With our enterprise app, we store about 2 dozen
CFCs in various scopes. Server, App, Session, etc. Each stored in the scope
most appropriate for it's use. It's helped us save memory, processing, and
offers better performance.

RE: cfc question...

2008-06-17 Thread Jason Durham

You don't *have* to use cfinvoke.  I prefer not to.

Once you have instantiated (created an instance of it in memory) the
object like you wrote below... you can 'invoke' any of the methods by
calling them via the object instance name.

!--- Instantiate agentLibrary component ---
cfset agentLibrary =
createObject(component,components.agents.agent).init(application.dsn
) /

!--- Get a list of agents, hold in query object called 'qAgents' ---
cfset qAgents = agentLibrary.getAgents() /

!--- Loop through agents and output their names ---
cfoutput query=qAgents
Agent Name = DB_FIELD_AGENT_NAME br /
/cfoutput

Soon you will find the answer to all of your questions regarding OOP or
CFCs will be it depends.  What does your agentLibrary CFC do?  If your
agentLibrary CFC interacts with a database (as you have indicated), then
what you're doing is correct.  Set a variable to hold your DSN/DB
credentials, and reference that variable when instantiating any
components that have to access the DB.

Thanks, Jason!  I'll work on this approach.
Seems much simpler to work with once the function

Here's a question:  Would I include argument variables
in a call like this?

cfset qAgents = agentLibrary.getAgents() /

I assume the parenthesis are empty because no arguments
are involved?

However, if I wanted to get a particular agent's info:

cfset qAgent = agentLibrary.get_agent_info( url.agentid ) /
if using a url, or
cfset qAgent = agentLibrary.get_agent_info( form.agentid ) /
if using a form variable to id the agent.
Correct?

Re: cfc question...

2008-06-17 Thread Mike Kear

[A]   One of the good things about cfcs, and its also quite confusing
to the beginner, is that there are several ways to code most of the
things you want to do.

For example, to pass in variables to a method,  you can do it this way:

cfset qAgent = agentLibrary.get_agent_info( url.agentid ) /
Or
cfset qAgent = agentLibrary.get_agent_info( agentID=#url.agentid# ) /

(In the second case you have to make sure that the name of the
variable being passed in is exactty the same as the argument name at
the top of your method)

The first way of doing it, is less typing, but it requires that you
pass in the arguments in the exact order you have them listed in the
function of your cfc.

If you call the method like this:
cfset qAgent = agentLibrary.get_agent_info( ) /

then you have to make sure your method in the cfc is written so that
it doesnt fall over if there is no argument passed in.   Normally
you'd give the argument a default value like so:

cfargument name=agentID type=string default=333 /

So if you try to run the method without giving it an agentID, it'll
run using '333' as the value of agentID.

[B] passing in the DSN: if you put your dsn into the application
scope, as in cfset application.dsn='datasource'  then your cfc will
work, by simply calling up a query as follows:

cfquery name=qAgentQuery  datasource=#application.dsn#
SELECT whatever, whatever2, whatever3, FROM tablename
/cfquery

That will work.  But it's considered bad practice, because it is
requiring your cfc to know about the application scope.  If you move
your site around or rebuild some of it ,   you might not have the
datasouce in the application scope any more.(yes i know, I konw -
these are things that hardly ever change, but trust me, this is
definitely good advice)

Instead, you should make sure that your CFC doesnt need to know about
anything in the whole world, apart from what you tell it.  This might
seem a bit esoteric when you're talking about just a datasource name,
but i have build cfcs with 60 or 70 variables they depend on.   Making
sure those puppies are all corralled and in a nice neat row when the
cfc is called is a bugger of a job if they're called from application
scope or request scope.  I found by using that method if i changed
anything in the request scope lots of things broke all around the
place.Instead, i now use a configuration cfc and pass that into
all the cfcs that need any configuration info (one day we'll talk
about how easy it is to let ColdSpring take care of all that for you!)
 and if i change any of the configuration structure, all i have to
make sure is the configuration cfc works correctly and everything else
will work.

So in short while it's not so vital now,  it will become vital one
day.  So just get into the habit of never requiring a cfc to know
anything about its environment.   You'll tell it what it needs to know
when it's instantiated.

So therefore,  if you have your datasource name stored in an
application. variable called application.dsn,  you'd instantiate the
cfc at the top of any page that uses it like this:

cfset agentLibrary = createObject('component',
'components.agents.agent').init(application.dsn) /

[C]  multiple uses of your CFCs.

You are having multiple subdomains arent you?  One for each of your
sales agents. This screams out to me that you're going to have a lot
of similar sites.   That means you're going to be having the same code
in multiple places.  It would be good to see if you cant have the cfcs
in a central place, and available to all the subdomains.That way
you're re-using the code.  That's a good thing becuase there's less
maintenance for you in the future, easier mainetnance,  more
reliability because you dont have dozens of copies of the same
queries, functions etc all over the place.If you can manage to put
your cfcs in a common folder, and available to all the subdomains
you'll make life a LOT easier for yourself in the long run.
Remember that getAgentName() is going to be the same for one agent as
another.   also getAgentCommission() or getAgentSalesAwardBonus()
methods are going to work the same for everyone.  If you have 30
agents to build sites for, you dont want to have 30 copies of those
cfcs scattered about.   What if you make a change to something and
amend 29 of the cfcs and forget one?   If they all share the same cfc,
then change it once and it's changed on all your subdomains.

So here's a site layout i suggest you try:

e:\inetpub\webroot\c21ar\components  (-- stores al your components,
organised into subfolders if necessary.)
e:\inetpub\webroot\c21ar\components\agents
e:\inetpub\webroot\c21ar\components\admin
e:\inetpub\webroot\c21ar\components\listings
e:\inetpub\webroot\c21ar\components\utilities


e:\inetpub\webroot\c21ar\subdomain1
e:\inetpub\webroot\c21ar\subdomain2

Re: cfc question...

2008-06-16 Thread Mike Kear

I havent seen that article, but I would suggest you put your cfcs in
their own area, since you want to re-use them as easily as possible.
(Thats one of the big benefits of CFCs).

so I'd put them in
e:\inetpub\webroot\c21ar\components\sales
e:\inetpub\webroot\c21ar\components\agents
e:\inetpub\webroot\c21ar\components\properties

or whatever seems logical.That way you have all your cfcs in
logical areas of the site,  and its' easy to find them when your site
starts to grow.(And if your client is the client i think it is,
it's going to grow!! - i have the same client elsewhere in the world)

At the top of your page, you make sure the component exists on that
page with something like this:

cfif not (isdefined(agent) )
  cfset agent = createObject(component,
components.agents.agent).init(application.dsn) /
/cfif

Then further down the page, any time you want to use a function that
is inside the agent.cfc all you have to do is call it, and give it the
variables it needs to know.   (Or more properly, all you have to do is
invoke that method, and give it the arguments it needs to know).

Such as:

cfset myquery = agent.get_agent_info( url.agentid ) /

Re: cfc question...

2008-06-16 Thread Mike Kear

I think you're nearly there, Rick.Just make sure you are following
the rules about how to set out paths for components:

if your component is in
e:\inetpub\webroot\c21ar\components\agents\agent.cfc   and the web
root is at e:\inetpub\webroot\c21ar,  then you would invoke the
component with the following: (Instantiate is another term that
confused me at first - how is 'instantiate' different from'invoke'?
answer:  it's the same thing)

cfset agentLibrary = createObject(component,components.agents.agent) /

Note the following:

[A] the component does not have .cfc as part of its name in the
createobject function.
[B] the path to the component is either a relative path from the page
calling it, or from the web root.Best to use the path from the web
root that way if you ever move the pages calling the components
around, they'll still work.
[C]  the path is expressed in dot notation, not using slashes.

Re: cfc question...

2008-06-16 Thread Mike Kear

Ok syntax error  forgot the closing quotes.   Make that:


cfset agentLibrary = createObject(component,components.agents.agent) /


And usually at the top of an object like that (if it's for the kinds
of things i think it is) you would have an init() functionthat you
tell the component the datasource name. That looks something like:

!--- Constructor / initialisation ---
cffunction name=init access=Public returntype=agent
output=false hint=Initialises the component
cfargument name=datasourcename required=true type=string /
cfset variables.dsn = arguments.datasourcename /
cfreturn this /
/cffunction


It seems a bit of extra typing to have that at the top of your cfc,
but for reasons of encapsulation (sorry for using the jargon!)  its
best to have the cfc so that if it needs to know something you'll tell
it, rather than have it rely on finding what it needs in application
or session scope or something.So if you have that init() function
in your component, you'd instantiate it by chaining the .init() method
when you invoke it.  ( You can chain methods one behind the other )

cfset agentLibrary =
createObject(component,components.agents.agent).init(
datasourcename ) /

Throughout your cfc, wherever any function needs to run a query on the
datasource, it will do it like so:

cfquery name=qThisQuery datasource=#variables.dsn#
   SELECT AgentID from Agents
  WHERE  GRPOffCE = cfqueryparam value=#officeid#
cfsqltype=cf_sql_varchar/
/cfquery


That way you can easily reuse the component without having to need the
datasource to exist in application scope or anywhere else for that
matter.  The cfc needs to know the datasourcename so you tell it that
when you instantiate the cfc.

RE: cfc question...

Alright... I finally got a path to work.

I put a components directory in the main subdomain folder
with a a cfc called agents.cfc

I used this path to access it:

cfinvoke component = components.agents

Whew... that was driving me nuts!

I originally wanted to use the component folder in the root
of the main app, instead of creating an additional components folder
in the agents folder (which is the root folder for all the subdomains),
but I couldn't get that to work... probably because the main app
component folder is out of the path of the subdomains.

Don't know if that correct or makes any sense, but whatever... I've got
a path working!

It's 1:23am on the east coast here in the U.S. and I'm sleepy and going to bed!
(But I'll sleep soundly now!)

Thanks, everyone!

Did you get it straightened out Rick?  Azadi gave you what you need.
You need to explicitly call the component using a path from the web root
(dot notation).

From Azadi's email...
cfinvoke component=dot.delimited.path.to.cfc.from.webroot
method=your_cfc_method_name_here ...

For your situation...
cfinvoke component=c21-ar.components.agent method=get_agent_info

A CF Admin mapping would be a reasonable approach. For example, you
might create a mapping /c21ar_cfcs (or whatever you want to name it)
that points directly to e:\inetpub\webroot\c21ar\components. Then,
anywhere you need to access the CFC, you would use c21ar_cfcs.agent.
Or in your case:

cfinvoke component='c21ar_cfcs.agent'
method='get_agent_info'
returnvariable='agent_info'
agent_id='#url.agent_id#'

RE: cfc question...

Yes, I did get it, finally, Jason.  Thanks to you and everyone
who has given advice!  I've got a lot to think about and consider
making the change from .cfm and includes to cfc's, but I'm off to
a good start, I think.  The first step for me is to get something
*simple* to work and then to build my knowledge from there.

What was complicating my path problem was the fact that the main website
has a component folder and a certain webroot.

The folder that is holding the templates for the subdomains is also the
webroot folder for those subdomains.

I was trying to use the components in the main website's folder, which is
above the subdomain folder (webroot folder for subdomains) in the folder
hierarchy.  That wasn't working.

I think what I had to understand is that the dot notation and paths
for the cfc's is logical, not physical.  I was trying to figure out some
way to jump back up two folder levels and down one to get into the
main website component folder...wasn't working.

I finally just created a component folder in the subdomain root folder
and then I could easily access it.

Does my newbie confusion make any sense?

 Did you get it straightened out Rick?  Azadi gave you what you need.
 You need to explicitly call the component using a path from the web root
 (dot notation).

a good start, I think.  The first step for me is to get something
*simple* to work and then to build my knowledge from there.

What was complicating my path problem was the fact that the main website
has a component folder and a certain webroot.

The folder that is holding the templates for the subdomains is also the
webroot folder for those subdomains.

I was trying to use the components in the main website's folder, which

You have to provide an _absolute_ path to a component via
cfinvoke and createObject() using dot notation.

You can get around that by doing something like this

cfset YourPathToCFCDir  = com.cf.model.

cfinvoke component=#YourPathToCFCDir#YourCFC
method=init
returnvariable=retinit
cfinvokeargument name=xslBasePath value=#someVar/
/cfinvoke


CreateObject(component, #YourPathToCFCDir#YourOtherCFC)

RE: cfc question...

Ok, let me see if I'm understanding this...

cfset agentLibrary =
createObject(component,components.agents.agent).init(
datasourcename ) /

The part above goes in the calling page before the cfinvoke
statement, right?  If so, how does this work with the cfinvoke statement?
Is agentLibrary above becoming the variable that will hold
all the data returned by the cfc function, agent?

And I've always defined my db's using
cfset dsn='datasource'
in my application.cfm file, so if I continue doing that, then
I guess the creation of the agentLibrary variable above would be:

cfset agentLibrary = createObject('component', 
'components.agents.agent').init(#dsn#) /
or something?

Or would defining the variable 'dsn' in my application.cfm become
an obsolete practice in the 'cfc era'???

Also, in your code below, I don't see the variable 'agentLibrary' being used
after creation (instantiation?)...so how does it fit into the cfc functionality?

 Subject: Re: cfc question...
 
 Ok syntax error  forgot the closing quotes.   Make that:
 
 
 cfset agentLibrary = createObject(component,components.agents.agent) /
 
 
 And usually at the top of an object like that (if it's for the kinds
 of things i think it is) you would have an init() functionthat you
 tell the component the datasource name. That looks something like:
 
 !--- Constructor / initialisation ---
 cffunction name=init access=Public returntype=agent
 output=false hint=Initialises the component
 cfargument name=datasourcename required=true type=string /
   cfset variables.dsn = arguments.datasourcename /
   cfreturn this /
 /cffunction
 
 
 It seems a bit of extra typing to have that at the top of your cfc,
 but for reasons of encapsulation (sorry for using the jargon!)  its
 best to have the cfc so that if it needs to know something you'll tell
 it, rather than have it rely on finding what it needs in application
 or session scope or something.So if you have that init() function
 in your component, you'd instantiate it by chaining the .init() method
 when you invoke it.  ( You can chain methods one behind the other )
 
 cfset agentLibrary =
 createObject(component,components.agents.agent).init(
 datasourcename ) /
 
 Throughout your cfc, wherever any function needs to run a query on the
 datasource, it will do it like so:
 
 cfquery name=qThisQuery datasource=#variables.dsn#
SELECT AgentID from Agents
   WHERE  GRPOffCE = cfqueryparam value=#officeid#
 cfsqltype=cf_sql_varchar/
 /cfquery
 
 
 That way you can easily reuse the component without having to need the
 datasource to exist in application scope or anywhere else for that
 matter.  The cfc needs to know the datasourcename so you tell it that
 when you instantiate the cfc.

 Let's say I have link on a page back to itself:

 a href='page.cfm?agent_id=20'Get Agent/a

 Then I have this in my page.cfm to invoke a cfc
 called 'agent.cfc':

 cfinvoke component='agent'
  method='get_agent_info'
  returnvariable='agent_info'
  agent_id='#url.agent_id#'


 My 'agent.cfc' looks like this:

 cffunction access='remote' name='get_agent_info' output='0'
 returntype='query'


 cfargument name='agent_id' type='string' required='1'/


 cfquery name='get_agent' datasource='x'

  select * from our_agents where agent_id = '#arguments.agent_id#'

 /cfquery

 cfif get_agent.recordcount
  cfreturn get_agent/
 cfelse
  cfreturn 0/
 /cfif

 /cffunction


You should var-scope your query variable. Also, you can't just return 0 if
the query has no data, since you have specified the return type as query
and 0 is not a query. Finally, the function doesn't need to be
access=remote unless you plan to call this as a web service or through
AMF.



 Now, let's say the invocation is successful and I have extracted query
 data.
 I know how to access all the query data back on the calling page (it seems
 counter-intuitive that the cfreturn variable, 'get_agent' in my example
 above,
 is referenced or 'renamed as 'agent_info' as the returnvariable in the
 cfinvoke...
 why the renaming?).


It's actually not counter-intuitive. Your calling code does not and should
not know anything about the internal implementation of your method. So
whatever variable you use within the method is not visible to anything
outside of the method. This is encapsulation, and it is the most fundamental
principle that underlies OOP. So nothing is actually renamed; when you
call the method you are explicitly assigning the result to the variable
agent_info, the same way you would with any other variable assignment.


 However, in my app I'm converting all the agent data from the query into
 session
 variables to customize my templates.

 Is there a way to do that in the .cfc or should I handle that back on my
 calling .cfm page?
 If I handle it in the .cfc, which I'd prefer in order to keep all
 processing out of the
 display page code, how would I return the session variables to the calling
 page?


This should be handled by the CFC, your views should be as agnostic as
possible about how they are used. If you want to cache this in the session
scope you could do something like:

cffunction access='remote' name='get_agent_info' output='0'
returntype='query'
cfargument name='agent_id' type='string' required='1'/
cfset var get_agent =  /

cfif not StructKeyExists(session, 'get_agent')
cfquery name='get_agent' datasource='x'
 select * from our_agents where agent_id = '#arguments.agent_id#'
/cfquery
cfset session.get_agent = get_agent /
/cfif

cfreturn session.get_agent/

/cffunction

Which will set the variable into the session scope the first time you call
this method, but will return the value from the session scope for all
subsequent requests within the same session.

Hope that helps,

Brian

my cfc's.  While learning, I've just placed the cfc in the same

Rick, I mostly initialize them in application scope in Application.cfc

Like this:

cfset APPLICATION.reportDAO = 
CreateObject(component,cfcs.reportDAO).init(dsn=APPLICATION.dsn) 

Then build a constructor in your cfc like so:

cffunction name=init access=public returntype=reportDAO output=false
 hint=Returns an instance of the CFC initialized with the correct 
settings.
  cfargument name=dsn
  cfset variables.dsn = arguments.dsn
  cfreturn this

Once you do all that, it's ready to use anywhere in the application. 

Just refer to it using the application scope:

cfset getReport = APPLICATION.reportDAO.monthEnd()

Puttin it in a cfc's directory is lame, but I'm sure more advice will roll in

 Another issue I've run into is how to help my calling page find

 folder and the calling page can't find it.
 
 Rick, I mostly initialize them in application scope in Application.cfc
 
 Like this:
 
 cfset APPLICATION.reportDAO =
CreateObject(component,cfcs.reportDAO).init(dsn=APPLICATION.dsn)
 
 Then build a constructor in your cfc like so:
 
 cffunction name=init access=public returntype=reportDAO output=false
hint=Returns an instance of the CFC initialized with the correct

   cfargument name=dsn
   cfset variables.dsn = arguments.dsn
   cfreturn this
 /cffunction
 
 Once you do all that, it's ready to use anywhere in the application.
 
 Just refer to it using the application scope:
 
 cfset getReport = APPLICATION.reportDAO.monthEnd()
 
 Puttin it in a cfc's directory is lame, but I'm sure more advice will roll in

You can do the same thing with functions too. It is pretty damn slick. I

 There is nothing lame about it (you gotta stick them somewhere). What he
 means is that you are going to want to stick them in memory (the application
 scope) cuz there is a lot of overhead with firing them up (instantiating or
 creating an instance of them) every time you need to use them. Basically you
 are caching them.

 You can do the same thing with functions too. It is pretty damn slick. I

Re: cfc question...

2008-06-15 Thread Mike Kear

Rick, I'm delighted to see you starting to work with the power of
CFCs.   I also had the same confusion as you did at first.  The
terminology for some of these OO concepts gets a bit confusing, so
perhaps i can help you by expressing some of the ideas related without
using the teminology.

Perhaps it might help to see your code with notation for the same thing. ..

cfset agent_info = agent.get_agent_info( #url.agent_id# ) /

Here you're naming a query variable agent_info, and it's being
populated with records from a function called agent.get_agent_into()
which has been given the parameter #url.agent_id#.That's exactly
equivalent to your code:

cfinvoke component='agent'
  method='get_agent_info'
  returnvariable='agent_info'
  agent_id='#url.agent_id#'

 (Although you dont need the hash signs around the url variable, so it
would more properly be expressed: cfset agent_info =
agent.get_agent_info( url.agent_id ) /  )

Compare this to something you've been using for a long time already like:

cfset variable1 = dateformat( createdate, d/mm/) /

You dont need to know how dateformat goes about its business of
transforming your variable in order to use it.  All the work is done
inside the function dateformat().  It's the same inside your function
agent.get_agent_info()

Now the function get_agent_info() has a limited number of things it
needs to know, and doesnt care about the rest of the world.   All it
wants to know is the agent_id it has to look up, and the datasource
name.It doesnt care about anything else, nor should it either.
This is the concept of 'encapsulation' which means briefly, that each
function has a specific thing it does, and it shouldnt know (or need
to know) anything except what you tell it.

That's just like the function dateformat() that you've been using
since you started with ColdFusion so long ago.  It doesnt know what
you're using the date for, where the date came from or anything else.
All it knows is you give it a date object and it gives you back a
string.

Does that help you?

 Let's say I have link on a page back to itself:

 a href='page.cfm?agent_id=20'Get Agent/a

 Then I have this in my page.cfm to invoke a cfc
 called 'agent.cfc':

 cfinvoke component='agent'
  method='get_agent_info'
  returnvariable='agent_info'
  agent_id='#url.agent_id#'


 My 'agent.cfc' looks like this:

 cffunction access='remote' name='get_agent_info' output='0' 
 returntype='query'


 cfargument name='agent_id' type='string' required='1'/


 cfquery name='get_agent' datasource='x'

  select * from our_agents where agent_id = '#arguments.agent_id#'

 /cfquery

 cfif get_agent.recordcount
  cfreturn get_agent/
 cfelse
  cfreturn 0/
 /cfif

 /cffunction

 Now, let's say the invocation is successful and I have extracted query data.
 I know how to access all the query data back on the calling page (it seems
 counter-intuitive that the cfreturn variable, 'get_agent' in my example 
 above,
 is referenced or 'renamed as 'agent_info' as the returnvariable in the 
 cfinvoke...
 why the renaming?).

 However, in my app I'm converting all the agent data from the query into 
 session
 variables to customize my templates.

 Is there a way to do that in the .cfc or should I handle that back on my 
 calling .cfm page?
 If I handle it in the .cfc, which I'd prefer in order to keep all processing 
 out of the
 display page code, how would I return the session variables to the calling 
 page?

 Thanks for any input!

 Rick

RE: cfc question...

I looked over the info and I'm sure I'll end up doing that,
but I still have to execute the code at some point, which leads
me back to the question of how to set up paths for the cfc's.

Let's say I've got a root folder of
e:\inetpub\webroot\c21ar
and a component folder path of
e:\inetpub\webroot\c21ar\components

How do I set the path when using the cfinvoke function?
All the examples I've used have the cfc in the same folder as
the calling document, so it hasn't been an issue.

Now that it is, I can't figure out how to satisfy the cfinvoke
function concerning the path to a cfc other that in the same folder
as the calling document.

I tried the source attribute in the cfinvoke function, but that
just returned an error any way I coded it.

CF Admin Mappings? IIS Mappings? Virtual Directories?
I know this is probably something simple, but I'm just not getting it.

Hints, anyone?

Thanks,

Rick

you can always use:

cfinvoke component=dot.delimited.path.to.cfc.from.webroot
method=your_cfc_method_name_here ...

same dor notation goes for createobject() function and cfobject tag

did my first comment not come through on the list yet? i do have it in
