Re: Best practice question for Application.cfc
Hi Azadi, Thanks for the follow up. In this case, I'm also using the listlast() function to extract the name of the containing directory. So, my guess is in that scenario, I would not need the hash because we're only dealing with a single folder name. If that seems off to you, let me know. N .

API best practice question
Hi Folks, I have a question regarding the best way to handle loading an API for the CMS side of our application. In this case, the API I am talking about not meant for remote calls but instead is meant to be for web developers creating themes and features for a web site who need to be able to make calls to the database (for example). So, it's meant to be like similar functionality in WordPress (http://codex.wordpress.org/WordPress_API's), Drupal, etc. We have these functions in a cfc and what I want to know is the best way to provide them to the user and developer. Loading them on every request seems like it would create unnecessary overhead although for all I know, that is the way other CMS' do it. Would it be better to use the onApplicationStart in Application.cfc to load this file into memory so that the functions can be called that way? If so, what would that look like? Or is there a better way? I expect that Mura, Coldbox, etc. have done this well but I haven't tracked that down. Thanks in advance, Nick .

Re: API best practice question
It sounds like you're dealing with a singleton, so instantiating it onApplicationStart() and placing it into the application scope would be perfectly reasonable. I let ColdSpring manage my singletons for me, but it's the same basic principle: Instantiate ColdSpring onApplicationStart(), and it resides in the application scope. Then when you need the bean, you ask CS for it. http://www.coldspringframework.org/coldspring/examples/quickstart/ HTH On Mon, Oct 15, 2012 at 7:45 AM, Nick Gleason n.glea...@citysoft.comwrote: Hi Folks, I have a question regarding the best way to handle loading an API for the CMS side of our application.

You can have a base Application.cfc, then use the EXTENDS attribute to create a new Application.cfc with customized settings, overridden event handlers, etc. Dave Watts, CTO, Fig Leaf Software http://www.figleaf.com/ http://training.figleaf.com/ Fig Leaf Software is a Veteran-Owned Small Business (VOSB) on GSA Schedule, and provides the highest caliber vendor-authorized instruction at our training centers, online, or onsite. ~| 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:352900 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: best practice on session variable persistence and ssl?
FYI, I found that storing the WDDX session data on disk was quicker than putting it in client scope. If your in a cluster then you most likely have a SAN or NAS anyway, so worth giving it a try and get away form using client vars. -- Russ Michaels www.bluethunderinternet.com : Business hosting services solutions www.cfmldeveloper.com: ColdFusion developer community www.michaels.me.uk : my blog www.cfsearch.com : ColdFusion search engine ** *skype me* : russmichaels ~| 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:351247 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: best practice on session variable persistence and ssl?
Hi Byron (and others), Quick follow up re: eliminating client variables (and wddx, etc.). Are you saying that you are able to maintain login persistence using sessions with the whole site in https so that you don't have to worry about logins being dropped with sessions (which is probably what we will do)? Or did you move to some other solution for login persistence? Another, related, example would be maintaining a url throughout a login. For instance, if you are on a site and click on a link to a password protected, you will be re-directed to the login screen. Once you login, we would like you to be directed automatically to the page. Sessions would be a handy way to do that. But, if we wanted to maintain the option to not have the whole site in https, then using sessions for this functionality would seemingly have the risk of sessions being dumped when you move into https and you would not be automatically redirected to the target page after login. So, again, I'd be interested in knowing alternate ways to handle that kind of scenario. (We have a way now but it may not be the most elegant).

This at one point was adding about 1.5 secs per request. We first moved to json serialization which seemed faster and smaller in size than wddx. Though, eventually we moved away from client vars all together and are just using session variables for all apps on our internal cluster. I doubt I'll every use client vars again, even in a cluster, and I've also learned to keep sessions as small as possible. One of our main issues with shared cf hosting are apps that have large sessions which hog resources. Came across a customer today with 100 sessions totalling about 45 MB, and that's just one example. High session timeouts are another factor in performance as well.

Re: best practice on session variable persistence and ssl?
Reason we were doing the session to wddx to client var, and reverse, was we are in a multi-server environment and not using the jrun session replication from server to server because of jrun's poor performance doing session replication across a cluster. Our load balancing scheme was (at the time) non-sticky. So a user could jump from server to server, so we needed a more reliable way of transporting the sessions from one server to another, since each user request could wind up at another server. So at the end of a request, we wddx the session structure to a client variable (and into the db), on the beginning of each request, we took the client var, reversed the wddx, and set all the session variables. Thus a lot of overhead. We wound up changing the load balancing to sticky sessions, so first request from a user goes to one server, and all subsequent request go to that same server unless it goes down. At that point it wasn't necessary to replicate the sessions with the wddx methodology. If a server dies, we are ok with a session lost and having the user potentially having to login again. This is a user experience vs. performance trade off we are willing to accept. From your description it sounds like you just want a user to go from http, to https, login, and jump to the original requested page. Session vars would be the way to handle tracking that requested page through the login process and then redirecting to the correct destination. Once the user is authenticated in the ssl portion of the site, subsequent secure request (from non ssl) would bypass the login and go directly to the requested page. Basically you would have 2 sessions, one http and one https, but after logging in the transition back and forth would be seamless, unless the https session times out from inactivity and the user has to log back in. This is all based on a single server concept. If you are trying to maintain the session across server instances then you would need a mechanism to replicate the user sessions across each instance in you cluster. Like we did with the session to wddx to client var and back to session, or Jrun in memory server to server session replication. Hope this helps, I think this thread got into two different areas; although somewhat related.

best practice on session variable persistence and ssl?
Hi folks, With our CMS / CRM application, we are looking at moving from a reliance on client variables towards more reliance on session variables, including as it relates to logins. One challenging scenario happens when a client is using SSL for ecommerce transactions. If a user logs in, using session variables for persistence, then goes to a page that is not in https and then goes to a page (e.g. an ecommerce screen) that uses https, sessions are dumped when the site goes into https and the login can be lost. We are probably going to solve that problem by just requiring the whole site to go into https. However, I wanted to know if there are other good ways to solve this. We have solved that kind of problem in a related scenario (with attribute scoped variables that need to survive https) by using wddx to store variables in the client scope and then get them back from there after moving into https. That has worked pretty well, but feels a bit complex. As we look at expanding our use of sessions, it seems like a good time to look at other options. So, are there other or better ways to keep session variables alive when a logged in user goes to an https encrypted page?

Re: best practice on session variable persistence and ssl?
As you would be aware going from non SSL to SSL will be seen as a new session by the browser, the one thing that you would need to do is remember to keep your session variables to a minimum. The more you keep in here the more it may end up costing you. What I mean by that is that you will need to way up the cost of growing in relation to how much memory you waste to a user being connected, the more users the more memory. Which means that in time you may find yourself having to go to more servers (clustered) quicker than you may need too. Now you may not be in a situation where that is going to affect you, but you should take that into consideration when deciding your longer plan for the life of your application. -- Regards, Andrew Scott WebSite: http://www.andyscott.id.au/ Google+: http://plus.google.com/108193156965451149543 On Wed, May 16, 2012 at 4:43 AM, Nick Gleason n.glea...@citysoft.comwrote: Hi folks, With our CMS / CRM application, we are looking at moving from a reliance on client variables towards more reliance on session variables, including as it relates to logins.

Re: best practice on session variable persistence and ssl?
your WDDX method has always worked well for me too, and I have used the same method for saving sessions as well. Just dump the entire session scope to WDDX and save it to the users record between page loads, then load it back it in later, such as after login or when switching to https.

Re: best practice on session variable persistence and ssl?
I'm going to guess that you're dropping sessions because your HTTP cookies aren't secure, and your HTTPS cookies are, issuing a new identity to the browser every time it switches back forth. Putting your entire site in SSL mode is not a bad way to go, a lot of sites are doing that these days, but I understand not wanting to go that way if you can help it. From the way you described it, it seems like the easy way may be to give your less-secure application side its own application name and cookie domain and path, then when you go secure, you get a new cfapplication name, and new cookies for the domain and path. If they hit the insecure site it wouldn't matter because the cookies can't collide. That may or may not work depending on how the application is laid out. Still though, I think I've done things like this and I don't remember having this problem. It was a lot of years ago though. You know, back when security was job #2 (or 3...)! Actually I wonder if somewhere in your code you are issuing new cookies on HTTPS that are secure, and those wouldn't be readable from plain HTTP. It's a possible security hole (http interception, man-in-the-middle - not likely but possible) to keep your cookies insecure, but it would probably fix it. If you insist on keeping it all tight together, you might be able to pass your HTTPS sessionid over a URL link to the insecure site after the user is authenticated. That way they should have the same exact session. Again, you're passing HTTPS cookies over HTTP, so consider if this risk is ok for you. nathan strutz [www.dopefly.com] [hi.im/nathanstrutz] [about.me/nathanstrutz] On Tue, May 15, 2012 at 11:43 AM, Nick Gleason n.glea...@citysoft.comwrote: Hi folks, With our CMS / CRM application, we are looking at moving from a reliance on client variables towards more reliance on session variables, including as it relates to logins.

One challenging scenario happens when a client is using SSL for ecommerce transactions. If a user logs in, using session variables for persistence, then goes to a page that is not in https and then goes to a page (e.g. an ecommerce screen) that uses https, sessions are dumped when the site goes into https and the login can be lost. We are probably going to solve that problem by just requiring the whole site to go into https. However, I wanted to know if there are other good ways to solve this. We have solved that kind of problem in a related scenario (with attribute scoped variables that need to survive https) by using wddx to store variables in the client scope and then get them back from there after moving into https. That has worked pretty well, but feels a bit complex. As we look at expanding our use of sessions, it seems like a good time to look at other options. So, are there other or better ways to keep session variables alive when a logged in user goes to an https encrypted page?

Funny you should mention high session time outs. I was given a task by a friend to look at, on something that I did many years ago. Since then they had another developer come in make some changes and the server fell over about 5 times a day, when I looked at it, the session was set to 2 days, I was like WTF...

I hear ya, since we eliminated the client variables all together and that whole wddx thing, our (internal) cf instances only go down during OS patches. Can't remember the last time I had to restart the service itself. Should also mention we are using jetty which has seemed to uptick performance all around. Now shared is another ball of wax.

Best Practice question about database access between Dev and Production Servers
Hello, I'm setting up a new environment and I would like to have the ability, through a web UI to copy objects from our production database (separate server) to a development/debugging database (separate server). My question is not about how to implement this but rather whether this is bad practice. It would involve exposing the production database on the dev server (via a datasource mapping in the cfadmin). This would mean that any developer that is using our dev server (my concern is contractors..) would be able to write a query against the production database and potentially download sensitive data. How to people handle this type of risk? One idea I had was to not hardcode the database username/password in the CFadmin and instead prompt for it when accessing this specific tool through the web UI. Does that sound like a reasonable means of protecting the data in the production database from developers working on the development server? Anybody have better ideas?

Re: Best Practice question about database access between Dev and Production Servers
Putting production data source connections on the development server is a practice you should avoid. I cringe whenever I see developers do this. Having the development DSN on the production server is less risky. Another path would be having the two databases linked at the database level and use database code to copy objects between servers, possibly triggered by a command issued by a Web UI. Database security is easier to control at the database level, and you wouldn't have to expose the production dsn on the dev Web server. I can't think of too many examples where you would want to copy production data to development using a ColdFusion Web GUI. I use specialized database tools or scripts, with no UI, when transferring database data between environments. If you really need this ability through a ColdFusion application, then having a password prompt is a bit better than using an embedded password. -Mike Chabot On Sat, Jan 28, 2012 at 4:02 PM, Brook Davies cft...@logiforms.com wrote: Hello, I'm setting up a new environment and I would like to have the ability, through a web UI to copy objects from our production database (separate server) to a development/debugging database (separate server).

RE: Best Practice question about database access between Dev and Production Servers
Generally, it is pretty bad practice to copy production data to any other network. You would most definitely not pass a SaaS 70 audit if they found that you were doing it. You would also not pass the same audit if they found that all of your developers had direct access to that data without going through permission granting hoops. That said, you may not have a need to worry about it if your data isnt really that sensitive in the first place. In which case, I think domain authentication would be the better way to govern the access. When people leave or contracts expire, the removal of their domain accounts would cover removing the DB access. Otherwise, you may find yourself managing the accounts individually for everything or changing the password every time someone leaves. Another option, which Russ mentioned, is scrubbing the data before copying it down to the dev network. Of course, you'd want to do that on the production network BEFORE copying it down to the other network. I have seen people do the scrubbing AFTER the move... which is kind of pointless. Just some things to think about. .:.:.:.:.:.:.:.:.:.:.:.

RE: Best Practice for multi-page form
Is it better to store the data for the survey in an array of structures or save each page to the database as the user moves through the form, This depends on if you require the entire survey to be filled out or if partial information is acceptable. We have done both. For most of the survey applications we've built we wanted the complete survey and throw away any that are incomplete so we uses session variables. 30-50 surveys a day is not much to be concerned about for resources as that is a relatively low volume in the scheme of things especially with session timeout of 20-30 minutes Dennis Powers UXB Internet - A website Design and Hosting Company P.O.

RE: cfc creation best practice
Russ, This use to be a huge problem in CF 6 and to a lesser extent CF 7 (probably related to Java 1.4). But as of CF 8 the penalty for instantiation is very slight once the class is compiled. So I have flip-flopped a little bit on this. I used to use a singleton approach and stuff everything in the app scope. But now I'm more judicious and only put things in there that demonstrate a slow instantiation issue. -Mark Mark A.

CFC argument best practice question
Hello, Just a quick Best Practices question. I have a CFC, I call a method and pass a slew of arguments to it. Internally it calls a private method using argumentCollection=arguments. My question is, should I repeat the argument definitions on the private method? The arguments are available regardless of whether or not the private method has the actual argument definitions. What is the best practice here? Define the arguments or just use them knowing they are the same as the public method?

Re: CFC argument best practice question
Presumably your private method is being called by multiple methods. It is definitely much better - at least in terms of documentation - to have those arguments clearly defined. :-) If, however, multiple methods do not call that private method, then there is no need for the private method to exist.

Re: CFC argument best practice question

Re: CFC argument best practice question
If you have a lot of arguments, one way to refactor that is to make a component that encompasses those arguments - essentially a bean, maybe a couple of beans if the arguments are unrelated. In your first public method, instantiate that bean with the arguments, then just pass that bean around. Follow that, and you've gone from just using components to actual object-oriented programming. nathan strutz [http://www.dopefly.com/] [http://hi.im/nathanstrutz] On Mon, Mar 7, 2011 at 10:06 AM, Brook Davies cft...@logiforms.com wrote: Hello, Just a quick Best Practices question.

CF OOP Best practice - reference tables
I have a table, members which I need to extract emails for a particular group. To get the emails I need to use reference tables. I might need to pull more information at a later date so I was going to return a query or an array of Beans to include everything from the members table. The query would look something like this.. select email, mem_id, ... from members m join members_group mg on m.mem_id = mg.mem_id join groups g on mg.group_id = g.group_id where g.group_id = 12 So in taking an OOP approach, would the best way be modifying the getAttributesByQuery function and throwing in a group_id argument in the Gateway, modifying the query to include these 2 reference tables in the argument is not null?

RE: Best practice for backup of CF Application server?
You might want to back up your web server configuration also For IIS6, here is the batch file we use to perform a scheduled backup of the metabase as well as an XML export. Hopefully it can benefit anyone else out there who isn't backing up their metabase regularly. (Note: gf-bigmama is a file server which holds our initial backups before they get shipped off-site, so replace that with a path you're comfortable with) @echo off md \\gf-bigmama\metabases\%computername% cd %SystemRoot%\system32 cscript.exe iisback.vbs /backup /b SchedBackup /v 0 /overwrite del \\gf-bigmama\metabases\%computername%\%computername%.xml cscript iiscnfg.vbs /export /f \\gf-bigmama\metabases\%computername%\%computername%.xml /sp /lm /inherited /children MOVE %SystemRoot%\system32\inetsrv\MetaBack\SchedBackup.* \\gf-bigmama\metabases\%computername% My understanding for IIS7 is that any configuration changes made to a site are written to web.config in the site's root folder, so backing up that file along with the rest of the site brings its settings along with it. I'm not familiar with where IIS7 stores its actual site listing though, I'm fairly certain they did away with the metabase itself though. I suspect there's some XML file hanging out somewhere that would just need to be copied. -Justin ~| Order the Adobe Coldfusion Anthology now! http://www.amazon.com/Adobe-Coldfusion-Anthology-Michael-Dinowitz/dp/1430272155/?tag=houseoffusion Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:338119 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

RE: Throttling CFMail - The reasons it's a good practice
You may have better luck just paying for SMTP services from a company who doesn't mind you sending that many emails at once. Last night I sent some code which does works to throttle email. I use it all the time. If you can't sort out how it works feel free to give me a shout off-list. It's pretty straight forward. Just so there's no confusion on the reasons to throttle the email - it may be a provider issue, but it's also a receiver issue. Even if your provider let's you send out a zillion emails at once, the ISPs of the recipients may block your mail (or block/blacklist your mail server or mail server IP) as a spam source. Many of the receiving ISPs (Yahoo, AOL, etc.) have robots that monitor the incoming mail and automatically block suspects. You can be blocked for a lot of reasons, but a couple of things that often trigger the alarm is: 1) too many concurrent connections from a mail server; or 2) to large a volume of incoming mail in a short period of time If your service providers IP or mail server get's blocked/blacklisted, then you are likely to have some real issues with your service provider. There is much reason to throttle outbound email, and the service provider is only half the equation. You also throttle email for the benefit of the receiving ISPs. Robert B.

Just wondering how others are dealing with public member signups that require an email activation? What I'm doing on a new site that I recently set up is sending out the activation as soon as someone registers. If a user tries to login with an account still in the unactivated state, they're shown an appropriate error message and given the option of having another activation email sent to them. I expire the unactivated accounts after 48 hours, deleting them completely from the books. This should allow someone to re-register using the same email address, in case their activation email was lost, overlooked, or caught by a spam filter.

Re: Best performace/practice for storing temp data
My thinking behind not using a db table was that I would need to clean it up somehow, and the fact that the client variable db was automatically cleaned out over time (imperfect assumption on my part) did that job for me. There are a lot of advantages to using the database and as a shopping cart becomes more and more complex, those become even more apparent. For instance, if your client decides at some point to track abandoned carts, this is far more easily done if that data is available directly from the database. It's a pretty simple function to just create a scheduled task that will clear out your cart tables on a regular basis, using a time stamp when you create the records to find the old ones. For my ecommerce product, pretty much everything is stored in the database, and then I just use a session variable with the cart ID, which also is saved to the user cookies and to the user table for logged in users as well. I also save a cart summary (items/total) to the session so I can display this on each page without recalculating the entire cart (which can be a LOT of calculation with a complex ecommerce app like mine). This gives you a pretty good persistent cart, with a very minimal amount of stuff needing to be kept in the session and/or cookies. So a lot depends on how simple you intend the cart to be, and the likelihood of it becoming more complex over time.

Re: Best performace/practice for storing temp data
Oops, just noticed the OP was specifically asking about shipping information. Personally, I generally use the session since if for any reason the CF server gets rebooted and it gets lost, the user is going to need to start the checkout process over again regardless. I do save their address information to a temp table, again, so it is available if I want to view that information on the merchant end, but otherwise I don't tend to use something like client scope for things like this that I don't need to persist for any length of time. But either will certainly work fine.

Re: Best performace/practice for storing temp data
Working on shopping cart app and stuck between storing shipping info in a db shipTable or in client scope. I'm hesitant to store shipping info into the db because some users might not complete the transaction and take up rows in the db. On the other hand if I store shipping info in the client scope I'm not sure if this would impact the server. Since Client variables are also typically stored in the database, I wouldn't worry too much about taking up rows. I would also not recommend using both the Session and the Client scopes - use one or the other.

You can copy the form vars to the session scope using structappend like so: cfset structappend(session, form, true) Or create another struct and store that in the session scope. cfset StrctNew() = session.myvars cfset structappend(session.myvars, form, true) Or something of that nature. I don't know if this is best practices...

Re: Best performace/practice for storing temp data
What Dave said about client scope and db rows. For my own cart I wound up using client variables. I felt they were more survivable than session vars. Restart CF and lose your session vars... bad news on a shared server where the host might have an uneven record of uptime. A cvar-based solution will typically survive a cf restart (user visits page, cf gets restarted while user reads content, next page hit is after restart and cvar cart contents persist). I haven't kept up with CF8's features but I believe they are in a struct now and much easier to work with as a result. My thinking behind not using a db table was that I would need to clean it up somehow, and the fact that the client variable db was automatically cleaned out over time (imperfect assumption on my part) did that job for me. -- -...@robertson-- Janitor, The Robertson Team mysecretbase.com ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:317426 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: Best performace/practice for storing temp data
I think a struct in a session is so much easier first you dont have to worry about cleaning up the database after the uses has finished or if the user drops out you dont have to create tasks to find redundancy data. you can have just as much hassle storing temp data in a database as in a session yes sessions can time out and you could restart the cf application but the database stuff would be unless if that happened also as there is then nothing to match the user with the database data!!! you then have to start scheduling daily, weekly or monthly tasks to delete redundancy data. ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:317430 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4
Re: Best performace/practice for storing temp data
Whatever you do, don't take ease of programming your solution as a valid way to look at the problem. You are talking about a cart checkout process. The payoff to your client's entire business model. Paramount is making something that will not step on its own you-know-what ... ever. As in fault tolerant. I'd cross session vars clean off the consideration list since they can go byebye for a variety of common causes. In my mind, we are talking about database or client vars. Only. Pick the solution that survives the most number of common, imperfect circumstances. -- -...@robertson-- Janitor, The Robertson Team mysecretbase.com ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;207172674;29440083;f Archive: http://www.houseoffusion.com/groups/cf-talk/message.cfm/messageid:317433 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

Best Practice: Looping over a query in cfscript?
So yesterday I was working in cfscript and needed to loop over a query. I
reviewed my options and decided for elegance sake that a for / in loop was
choice. Only problem is that for / in loops in cfscript can't be used with
query objects. After trying a few things, I fell back and punted with the
following code:
qGetTheme = siteGW.GetSiteThemeValuesByThemeID(ARGUMENTS.themeID);
colList = qGetTheme.columnlist;
for ( item=1;item = ListLen(colList);item++ ) {
SiteInfo.theme[ListGetAt(colList,item)] =
qGetTheme[ListGetAt(colList,item)][1];
}
I know this works, and is perfectly legit, but I'd love to see if there's a
better way of doing this in cfscript. Anyone?

Re: Best Practice: Looping over a query in cfscript?
Hm, I'd think I'd do that loop the same way with cfloop - there is no
cfloop shortcut for looping over the query columns. What you have
there is fine though I would personally use an array instead of a list
in the loop as it is generally more efficient and easier to read in my
opinion:
qGetTheme = siteGW.GetSiteThemeValuesByThemeID(ARGUMENTS.themeID);
cols = ListToArray( qGetTheme.columnlist );
nCols = ArrayLen(cols);
for ( item=1;item = nCols; item++ ) {
SiteInfo.theme[ cols[item] ] = qGetTheme[ cols[item] ][1];
}
Looping over the rows of the query would be slightly different
however. Here is a neat but undocumented way to loop a query in
cfscript:
cfscript
foo = QueryNew('');
bar = [1,2,3,4];
QueryAddColumn(foo,'bar','integer',bar);
while(foo.next()){
writeoutput(foo.bar[foo.getCurrentRow()]);
}
/cfscript
Output would be: 1234

This isn't looping over the query, though, right? It's looping over the columns in the first row only.

cfscript
// Create Query
myQry =
QueryNew(ColumnA,ColumnB,ColumnC,VarChar,VarChar,VarChar);
// Load Query With Data
for (i=1; i LTE 10; i=i+1){
QueryAddRow(myQry, 1);
QuerySetCell(myQry, ColumnA, RandRange(1, 2), i);
QuerySetCell(myQry, ColumnB, RandRange(1, 2), i);
QuerySetCell(myQry, ColumnC, RandRange(1, 2), i);
}
/cfscript
!--- Dump the Query to see what is in the recordset ---
cfdump var=#myQry#
cfscript
// Loop Over Query and write out the data
for (q=1; q LTE myQry.RecordCount; q=q+1){
writeoutput(myQry.ColumnA[q] -- );
writeoutput(myQry.ColumnB[q] -- );
writeoutput(myQry.ColumnC[q] br /);

RE: CFC Objects (Best Practice)?

Yes, if you can share them among multiple users, or multiple requests for a single user. CFCs are really no different than any other sort of variable in this way. They are more expensive to create than many other variables, though, so it's worth looking for caching opportunities for them when you might not otherwise.

RE: CFC Objects (Best Practice)?
Randy,
If your CFC is a collection of methods then this is fine.. But if you intend
on persisting the return value (say in the session scope) then you may end
up with some memory issues.
We found that storing a return query from an application cached CFC in the
session scope caused memory to be allocated on the heap that could not be
recoverred by Garbage collection. By default the pass by reference caused
the object returned from the application scoped method to live in the
application scope and be referenced by the session scope.
I wrote about it here.
http://www.coldfusionmuse.com/index.cfm/2008/2/12/leaky.heap.jvm
So.. If you understand the implications then yes... Storing in the
application scope is an option.
I have found however, that there is not a lot of overhead to the
createObject( ) call once the CFC is compiled (run for the first time) so
caching is often unnecessary.

Re: CFC Objects (Best Practice)?
The scope I used would depend on the manner in which I was using the CFC.
Something used on every request, like a user.cfc or cfc for logging I
would use the application scope, however if it's something thats used
less often but needs to exist across multiple requests I would use
session variables, if it only needs to exist for the life of the single
request, I use the request scope.

RE: CFC Objects (Best Practice)?
Where to store the object would depend on the nature of the object...
Does it have internal state (variables) that are specific to a given
user (so, maybe use session, but definitely not application), or is the
object sharable by every user (so, application might work).
I tend not to cache lite CFC objects in either session or application
scope, just to keep things simple, especially during development when
you are changing the CFC and the cached versions are old... This can
get really annoying.
One habit I found myself in is assigning CFCs to the request scope in
application.cfm... This gives every page access to them via request and
those pages don't need to know where the real object lives... It could
be session, or application, or created on-the-fly in application.cfm.
This is probably not be a good idea to do in all cases... it may some
your code read funny; using session.shopingCart probably feels better
than request.shopingCart. But for global sorts of things like you are
probably talking about, pulling the object from session or application
and assigning it to request might not be a bad idea.

Re: CFC Objects (Best Practice)?
I apprecaite all the comments.
I was considering storing lookup values in either scope for easy referencing
throughout the application.
Not everyone would be used but many are used multiple times.
Ex: Being able to call the function: application.lookup.company('some
company name');
would return the query scope qCompany and contain things like name, address,
etc...
Or something similar. This is where data may change frequently but not the
database structure.
I can see advanatages of both session and application scopes. My initial
thought was be reducing any overhead by creating the objects either
onApplicationStart or onSessionStart that way they would already exist for
the user's request.
(Mark.. I will read up on your blog after my meeting.. Thanks!)

SQL Server connection best practice?
Hi all, I'm not even sure how to pose this question, so I did a poor job of searching the archives, if this question has already been answered. We're running CFMX7 and SQL Server 2000 in Windows2003 Server. I know there are a variety of ways that one can get CF to talk to a SQL Server box: ODBC, JDBC, Named Pipes, and so on. I don't even pretend to know what all of that really means. The question is what's the best practice these days? I think at one point, ODBC was faster, but then JDBC was recommended, and now I'm no longer sure. This came up because I ran a query in SQL Server query analyzer that returned the result set in 0 milliseconds. however, running it using CFQUERY (debugging enabled) showed that the query took about 800ms to execute. The recordset returned is pretty big, so I'm assuming that the bulk of the 800ms is the transfer time, and that got me to thinking about the above question. Any guidance is appreciated.

I think at one point, ODBC was faster, but then JDBC was recommended, and now I'm no longer sure. ColdFusion only supports JDBC, so you'll be using JDBC. You can either use a pure Java JDBC driver, or you can connect to ODBC datasources using SequeLink as a JDBC proxy of sorts. I'd strongly recommend using just JDBC.

Re: SQL Server connection best practice?
Okay, that's kind of what I thought. I think the SequeLink thing is what I was thinking of wrt to the ODBC driver. Thanks, Dave. ColdFusion only supports JDBC, so you'll be using JDBC. You can either use a pure Java JDBC driver, or you can connect to ODBC datasources using SequeLink as a JDBC proxy of sorts. I'd strongly recommend using just JDBC.

RE: SQL Server connection best practice?
Ben, Search House of fusion for a recent thread on query optimization as well... There was an interesting issue with a stored proc taking too long and it turned out to be permissions on the database (made me go hm.) -mark -Original Message- From: Ben Mueller [mailto:[EMAIL PROTECTED] Sent: Wednesday, January 02, 2008 2:17 PM To: CF-Talk Subject: SQL Server connection best practice? Hi all, I'm not even sure how to pose this question, so I did a poor job of searching the archives, if this question has already been answered. We're running CFMX7 and SQL Server 2000 in Windows2003 Server. I know there are a variety of ways that one can get CF to talk to a SQL Server box: ODBC, JDBC, Named Pipes, and so on. I don't even pretend to know what all of that really means. The question is what's the best practice these days? I think at one point, ODBC was faster, but then JDBC was recommended, and now I'm no longer sure. This came up because I ran a query in SQL Server query analyzer that returned the result set in 0 milliseconds. however, running it using CFQUERY (debugging enabled) showed that the query took about 800ms to execute. The recordset returned is pretty big, so I'm assuming that the bulk of the 800ms is the transfer time, and that got me to thinking about the above question. Any guidance is appreciated.

cfwindow best practice?
Hi,
I'm in the process of converting an older version cf app to cf8. cfwindow is a
'star' tag for the new version. Form submission/process goes to the same page.
The previous form looks like this:
form
e1, e2,
function 1 (using input type=submit name=myFunction1 value=Do A)
function 2 (using input type=submit name=myFunction2 value=Do B)
function 3 (using input type=submit name=myFunction3 value=Do C)
close form
But with cfwindow the above technique won't work, that is, even if a user
clicks on {myFuction2} button, only the first function would be recognized.
And in my experience, to send the request to the same script which uses
cfwindow one would do something like
cfform
function 1 (using input type=submit name=myFunction1 value=Do A)
onclick=javascript:ColdFusion.Ajax.submitForm()
close cfform
cfform
function 2 (using input type=submit name=myFunction2 value=Do B)
onclick=javascript:ColdFusion.Ajax.submitForm()
close cfform
But the above approach is clumsy because many shared elements would have to be
repeated for one thing. Is there a better way to do it?
Thanks.

The cfthread / version was always faster. Your environment is going to largely dictate what kind of advantages you see from threading tasks in your code. Also remember anytime you need to join the threads together, which would be the case here, your code is still going to have to wait for the slowest running thread. That means if you have a feed that on average takes 900ms to return its results, that's not a bottleneck threading your code will fix. The benefit really comes from when you have 4 processes that each takes 900ms to complete. You're going to have to wait at least 2800ms for that task to finish when run in serial. By threading the processes and running them in parallel, you'll drastically reduce the wait time since all of those tasks run at the same time. You could end up reducing the wait time by 2100ms. You'd really notice the benefits of threading the requests if you start running into network latency issues or issues with the server returning the results in timely manors. -Dan ~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;160198600;22374440;w Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:294843 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.4

This will be the main concept. Code or database organization or isolating code from languages are the main issues.

I think creating PO files and managing them is more easier than any resource bundle packages. But I will explain all possible methods including some custom ones such as XML or DB usage. - XLIFF, while i don't like XML for humans, there's no denying this standard increasing use outside the translation business. see: http://www.oasis-open.org/committees/xliff/documents/xliff-specification.htm that's old (version 1.1 from 2003) there's actually a 1.2 spec someplace but i can't find it on any public site. for some XLIFF/ICU blood guts see http://source.icu-project.org/repos/icu/icuhtml/trunk/design/locale/xliff-profile-icuresourcebundle-1.2.htm Good to know. Let me check this also. - writing systems, at least directionality when it comes to handling layouts, etc. I will present some Frameworks code also with best i18N practices. Specially layout management is an interesting approach. I also want to share layout management in FarCry for multi language applications. Because still there are lots of dilemmas on FarCry template management. non-technically maybe: - why bother? This is what I am trying to do now. Why this topic is important? Please share some more suggestions on this. :) - the importance of professional translators vs the know anybody who speaks Ethiopian? approach. Yes!
