IWDCRInfo.setDCRName

Hi,

I am fiddling with IWDCRInfo.setDCRName. What I want to achieve is to save the DCR automatically for the user in a subdirectory in the data folder which may or may not exists upon save. Now this is causing problems !!

A simple IWDCRInfo.setDCRName("menu") works fine.
But if I try IWDCRInfo.setDCRName("/site/menu") and the site folder does not exist I get the error "save was unsuccessful. Invalid path". Isn't it possible to have the function create the folder if it does not exist ?
Or is it possible by javascripting to determine whether a given path exists on the server ?

Regards
Vaqas

You would need to use a callServer and a server-side script to create the directories for you. More than likely, you would need to think through the ramifications of the asynchronous nature of callServer during your Save process. Essentially, you'll probably want your save handler to return false, then the callback from your callServer could "re-start" the Save process by calling IWDatacapture.save once the directories are created.

Strictly speaking, he would have to think through the ramifications of the asynchronous nature of setDCRName to begin with.
Second parameter is a callback, default timeout is 1 min. See FormAPI Developer’s Guide

Ok, in case anyone wondering this is how I did it. Hopefully this will save a lot of people from being frustrated.

Event registry & save function:


// HANDLER
IWEventRegistry.addFormHandler( "onSaveValid", generateDCR );

// GENERATE DCR NAME & CALLSERVER
function generateDCR() {
 // set the dir
 savepath = IWDatacapture.getItem('/ARTICLE/PATH').getValue();

 // set autonaming DCR
 DCRname = IWDatacapture.getItem('/ARTICLE/TITLE').getValue();
 DCRname = DCRname.replace(/ /g,''); 

 var server = window.location.hostname;
 var parameters = new Object();
 parameters.path = "/default/main/Branchname/WORKAREA/Common/templatedata/HereHere/Datatype/data/" + savepath;

 IWDatacapture.callServer("http://"+server+"/iw-bin/createDirs.ipl",parameters, true);

}

// WILL BE CALLED BY IPL CALLBACK
function saveDCR( ){
 IWDCRInfo.setDCRName( savepath + DCRname ); 
 checkStatus();
}

// SAVING TAKES PLACE HERE
function checkStatus() {
   var status = IWDCRInfo.getStatus();

   if (status == IWDCRInfo.PENDING) {
      setTimeout("checkStatus()",2000);  // call in 2 secs
   } else if (status == IWDCRInfo.AVAILABLE || status == IWDCRInfo.UNAVAILABLE ) {
    IWDatacapture.save();  // save new DCR or override it anyway
   } else {
      // Error!! Do something here
   }
}

createDirs.ipl:
[html]
use TeamSite::CGI_lite;
use File: Smiley Tongue

ath;
use CGI qw(:standard);

my $cgi = TeamSite::CGI_lite->new();
$cgi->parse_data();

my $path = $cgi->{form}{path};

opendir(DIR, $path) || eval { mkpath([$path], 0, 0775) };

`chmod 777 $path`;
`chgrp interwvn $path`;
`chmod g+x $path`;

Not bad, just year and a half too late.
Sample of setDCRName callback Usage has been posted here, note that 'checkStatus' is method's Parameter, not a direct call
