CF -File import check

Posted on 2011-03-08

Last Modified: 2012-05-11
I have the following procedure where if the import file exists then the import procedure runs and the file is moved to an archive folder and then the file is deleted since another import would mess up the data.  Then a email is generated informing that it has run. There is just one import per day.  We have found out that sometimes another file is sent in error.  What I am trying to do is check the archive folder for testfile.csv and if the file date is equal to Now() then do not run the procedure since that means that it is today's file import and it has already run and also to send a email alerting that another file is trying to import.  

Any help is appreciated.
<cfif FileExists("C:\Inetpub\wwwroot\testfile.csv")>

		
		  
	   <cffile action="read" file="C:\Inetpub\wwwroot\testfile.csv" variable="csvfile"> 
		<cfloop index="record" list="#csvfile#" delimiters="#chr(10)##chr(13)#">

Import procedure


<cffile action="copy" source="C:\Inetpub\wwwroot\testfile.csv" destination="C:\Inetpub\wwwroot\dataarchive\testfile.csv">
		<cffile action = "delete" file = "C:\Inetpub\wwwroot\testfile.csv"> 

<cfmail to="DBA@company.com"
					from="webmaster@company.com"
					subject="file complete successful"
					type="text">
				file complete successful
	</cfmail>

if the file date is equal to Now()

If by you mean the file exists and has today's date, try something like this.  Or you could modify it to check the last 24 hrs instead.

<cfset isNewFile = true>
<cfset filePath = "C:\Inetpub\wwwroot\testfile.csv">
<cfif FileExists(filePath) >
    <!--- if it was uploaded today --->
    <cfif dateCompare(now(), GetFileInfo(filePath).FileLastModified, "d") eq 0>
         <cfset isNewFile = false >
     </cfif>
</cfif>

<cfif isNewFile >
     .... do processing ...
</cfif>

At this point don't I need to check if it is true or false before processing?

<cfif isNewFile >
     .... do processing ...
</cfif>

<cfdirectory

That's what it does. It's shorthand for saying

<cfif isNewFile eq true>
    it's okay to do processing
</cfif>

It has a problem with this

Element FILELASTMODIFIED is undefined in a CFML structure referenced as part of an expression.  
 
 
The error occurred in C:\Inetpub\wwwroot\: line 25
 
23 :
24 : <cfif FileExists("C:\Inetpub\wwwroot\")>
25 :     <cfif dateCompare(now(), GetFileInfo(filePath).FileLastModified, "d") eq 0>

<cfif FileExists("C:\Inetpub\wwwroot\")>

That's not a file, it's a directory.  Both functions require the CSV file path

<cfif FileExists("C:\myFileName.csv")>
   <cfif dateCompare(now(), GetFileInfo(C:\myFileName.csv).FileLastModified, "d") eq 0>
....

I removed the actual file names for security reasons, it is a valid path I am working with.

No, only moderators can do that.  But best not to post it at all.  Btw: you could always replace the path with "c:\path\to\dummyFileName.csv".

Anyway, are you running CF8+?  If you're on MX7 you'll have to use cfdirectory.  Otherwise, maybe CF8 doesn't like the direct variable access.  Try this instead


<cfset isNewFile = true>
<cfset filePath = "C:\Inetpub\wwwroot\testfile.csv">
<cfif FileExists(filePath) >
    <!--- if it was uploaded today --->
    <cfset csvInfo = GetFileInfo(filePath )>
    DEBUGGING: <cfdump var="#csvInfo#">
    <cfif dateCompare(now(), csvInfo.FileLastModified, "d") eq 0>
         <cfset isNewFile = false >
     </cfif>
</cfif>

.... rest of code

The dump showed all the file information correctly and then gave this error

      Element FILELASTMODIFIED is undefined in CSVINFO.

<cfif dateCompare(now(), csvInfo.FileLastModified, "d") eq 0>

Sorry my bad. The field name is "lastModified" not "FileLastModified".  

ie Should be
<cfif dateCompare(now(), csvInfo.LastModified, "d") eq 0>
