Re: Finding if a key exists in a struct based on a variable name

IIF does not short-circuit
(http://en.wikipedia.org/wiki/Short-circuit_evaluation), meaning that
your DE() gets evaluated even if the condition is FALSE. So, this will
break:
#iif(false, notFalse, false)#
since notFalse does not exist. Same here:
#iif(true, true, fols)#
since fols does not exist. And finally your code:
#iif(false, DE(x.classAssign[#y#head]), DE(''))#
breaks since x.classAssign[NAMEhead] does not exist.
DE evaluates a STRING parameter and finds double-quotes. If you pass in
a variable, it looks for the value of that variable. Since you are
passing x.classAssign[#y#head], it looks for x.classAssign[NAMEhead]
and breaks.
This will work: evaluate(DE(x.classAssign['#y#head'])) - notice the
single-quotes surrounding #y#head! This is because we don't want DE to
escape this, so we don't want to wrap it around double-quotes!
Here is the code (I used no value instead of , but it's still the
same code that you use):
cfset x.classAssign = {
NameHead = this head,
NoNameHead = that head
} /
cfoutput
cfset y = Name /
#iif(StructKeyExists(x.classAssign,#y#head),
evaluate(DE(x.classAssign['#y#head'])), DE(no value))#hr /
cfset y = NoExist /
#iif(StructKeyExists(x.classAssign,#y#head),
evaluate(DE(x.classAssign['#y#head'])), DE(no value))#hr /

#DE('x.classAssign[#y#head]')#

Creating a custom ajax error
Has anyone used cfhttp to throw an ajax error that returns a JSON object and error code 500? I'm looking for a code snippet of your onError() method. I'm using jQuery and am also trying to decide how to handle it on the client side. Specifically looking for when a session expires and when a server error occurs what to do on the client side (session expiration refreshes the page to login panel,etc). ~| 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:336898 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Creating a custom ajax error
There are a couple of ways you can do this. I'm going to do a blog
entry on this in a few minutes with a full example, but, you can have
logic like this:
(pseudo-code obviously for this part)
if I need to login:
if ajax request, throw an exception with a specific message
else redirect to login.cfm
Then in your JS code, make use of the global Ajax object to see errors:
$.ajaxSetup({
error:function(x,e){
if(x.status == 500 x.statusText ==
SessionTimeout) {
alert(Your session has timed out.);
location.href = 'index.cfm';
}
}
});

Re: Creating a custom ajax error
That's exactly what I was looking for Ray. So the $.ajaxSetup() method handles the errors and redirects expired session. I knew there was a way to do this outside of my ajax requests but wasn't sure if I needed to create a proxy method or otherwise. Also, I noticed that you are expecting a string SessionTimeout which is exactly what I am doing, just not in the same place (hence asking for some advice since I am duplicating this all over the place). So this leaves me with another thought about passing the error back to the client. If a ColdFusion error occurs, I would really like to have a structure to work with but how would you identify that it indeed is a server error? I would want an indicator and a structure at the same timeor maybe you can advise this as well?

Re: Creating a custom ajax error
You're correct if the application was something on the public end but during black box testing is when this would be useful. Before go-live I would like the user (or another client based delivery system) to catch errors and pass them back to a ticket. I can then go into my error log files and see more detail of what happened or get a little more information about how to duplicate and resolve the issue. Following, I would return something vague once black box testing is complete like 'were sorry an error has occurred' and then refresh or catch it and move on, etc. So to join the two, the real answer is yes and yes :) I would want to say whatever I want and handle it however I want based on when in the SDLC it is occurring and who is getting the error. Thanks for helping me on this. I know there are a lot of ways to do it but that's my problem.

So I plan a blog entry on this, but taking my example of ajaxSetup:
$.ajaxSetup({
error:function(x,e){
if(x.status == 500 x.statusText == SessionTimeout)
{
alert(Your session has timed out.);
location.href = 'login.cfm';

});
I'd simply add an else to the IF there to do X,where X is either the
vague handler or the more verbose one you spoke of.

!---if the request is ajax, throw an error that can be returned

StructFind(requestHeaders,X-Requested-With) eq XMLHttpRequest
cfthrow errorcode=500 message=ColdFusion Error
cfelse
cfdump var=#arguments.exception#
/cfif
/cffunction
Client side script:
$.ajaxSetup({

alert(Your session has timed out.);
location.href = 'login.cfm';
}
else if(x.status == 500 x.statusText == ColdFusion Error){
alert(x.statusText);//test for coldfusion error
}
}
});

Re: WHERE Left(str,5) = 'string' VS WHERE str LIKE 'string%'
In SQL Server go with like str%. The reason is that like str% is sargable and functions are not. Functions also have overhead that native set-based SQL does not. I would assume the same is true with mySQL. Native SQL is usually faster than functions as a general rule, unless the equivalent SQL is wildly complex relative to what the function is doing for you. -Mike Chabot On Wed, Sep 8, 2010 at 1:27 PM, Michael Grant mgr...@modus.bz wrote: What about mySQL?

Re: WHERE Left(str,5) = 'string' VS WHERE str LIKE 'string%'
mike, Please let us know what you find out. I'm very curious of this myself. As the document clearly states, mysql will use an index when you use a like but don't start the string with a wildcard. So we know that Left(str,5) = 'string' VS WHERE str LIKE 'string%'both will use an index. The question now becomes the cost of using LEFT vs using the LIKE. BTW, I assume you meant where left(str, 6) = 'string'. ~| 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:336918 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm

Re: Preserve HTML format when inserting into HTML
But like I said earlier, I created a workaround so I'm not stressing about it. It's just odd. I have found the same problem with a different XML file. I am going to try to put together a proof of concept to see if other people besides me can recreate this issue. ~| 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:336920 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Preserve HTML format when inserting into HTML
Ok, guys, I have a working proof of concept. At least on my server, this simple 4 line code example illustrates the problem. To recreate, dowload this file: http://techfeed.net/xmlHTMLTest.zip And then follow these steps. 1. Extract the zip to your ColdFusion sites directory. 2. BEFORE RUNNING THE .CFM, open up parkRegions.xml and note how the first region has normal (not escaped) HTML tags. 3. Run xmlHTMLTest.cfm (no output is generated, so you'll just see a blank page). 4. Open parkRegions.xml again and note how the first region now contains escaped HTML. At least, for me on my servers it does (I tried this code on two different servers). Can you see what I'm doing wrong? ~| 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:336921 Subscription: http://www.houseoffusion.com/groups/cf-talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/groups/cf-talk/unsubscribe.cfm
Re: Preserve HTML format when inserting into HTML
Ray,
In addition to my previous email with proof of concept code, I am able to
reproduce my problem using your code below by adding this cffile tag to the end
of your code:
cffile action=write file=#expandPath('foo.xml')# output=#toString(x)#
Weird. I can't reproduce this:
cfset s = font color=redbfoo/b/font
cfxml variable=x
root
child name=one /
/root
/cfxml
cfset x.root.child[1].xmlText = s
cfoutput
#x.root.child[1].xmltext#
p
#s#
/cfoutput
The value is NOT escaped in the XML, nor in the original variable.

Problem opening a CF created .XLS in OpenOffice.
I have created a cfc that you pass in queries and get back an xls with multiple worksheets. This seems to work great and opens perfectly in Microsoft Excel. However if I open it in OpenOffice I get a screen telling me it's importing text and asks me to choose the language. Then the content of the document is actually just the XML markup as plain text within two cells.

Re: WHERE Left(str,5) = 'string' VS WHERE str LIKE 'string%'
I ran a quick test
CREATE TABLE HoF (
ID INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
LastName VARCHAR(100)
) ENGINE = InnoDB;
insert into HoF (LastName) values ('Smith');
insert into HoF (LastName) values ('Smithville');
insert into HoF (LastName) values ('Jones');
insert into HoF (LastName) values ('Smithy');
insert into HoF (LastName) values ('Smit');
select lastname from HoF where left(lastname, 5) = 'smith';
select lastname from HoF where lastname like 'smith%';
explain extended select lastname from HoF where left(lastname, 5) = 'smith';
explain extended select lastname from HoF where lastname like 'smith%';
create index lname_index on HoF (lastname(100));
explain extended select lastname from HoF where left(lastname, 5) = 'smith';
explain extended select lastname from HoF where lastname like 'smith%';
Conclusion, which seems pretty obvious now, is that Like is the better
route. LEFT will have to read every row so it can execute the LEFT function
against it while the LIKE column will filter out columns that it doesn't
meet the condition.
It's really late and I had a tough day at work so please correct me if
anyone sees anything wrong with my analysis.
