iwpt_compile - 2 DCR's to 1 Template

jajtiii

Greetings,

I need utilize iwpt_compile to take 3 DCR's and insert the values into one template.

I am interested in troubleshooting this, but I cannot seem to find the location where the code modifications would occur.

Would I try this with a sub-routine in the Workflow? I only want this to apply to one file in the workarea.

Thanks,

jt

Well, you're certainly going to have to modify your presentation template, to make it aware that it's dealing with multiple DCRs. The normal <iw_value name='dcr.whatever'/> tags will, by default, only pull data from the first DCR. If you wanted the same value from the second DCR, you'd need something like <iw_value name='dcr[1].whatever'/>.

I believe you could also loop over all of the DCRs with something like this:

<iw_iterate var='dcr' list='thisDCR'>
    <iw_value name='thisDCR.whatever' />
</iw_iterate>

You also need to figure out how/when iwpt_compile.ipl is going to be invoked. As you say, it could be a part of a workflow, although it sounds like this might be a "one off" in which case it might make the most sense just to do it manually from the command line.

I think you are correct, in that it should be one off.

I basically want the client to go to the DCR's to edit them. So, let's say we have bullet1.dcr, bullet2.dcr and bullet3.dcr.

Then, when ANY of these dcr's are edited (and saved through a save or generate), the output file (bullets_body.inc.html) will be created from ALL THREE of the dcr's.

I agree that changes may need to be made to the tpl, but first I need to figure out where to make the callout (I assume that I will need to make a routine for this). I can't seem to find where to configure what happens when someone selects a file and clicks EDIT (and, correspondingly, hits SAVE or GENERATE thereafter).

Thanks for your input.

I see now.

Youve got a few choices.

You could use a callServer method, invoking it in an onSaveDone event in FormAPI
You could create a workflow that gets kicked off in response to the tt_data workflow command
As you say, you could create a custom menu item that the user would invoke manually

Unfortunately, one of the limitations of the TeamSite architecture is that, while it's certainly possible for a generated page to have multiple DCR "masters," there's no way to indicate that via the linkage that TeamSite uses to tie a generated page to the DCR. Each generated page has exacty one "master" DCR. So you can't have a user edit the generated page, and then they get a choice of which DCR to edit. That would be nice, because then the user could just click "generate" no matter which DCR they chose, and iwgen could handle the magic of making it work.

Ok, for the life of me, I need some assistance.

I have only used the formapi for simple js functions.

How can I use it to actually perform intiate an iwpt_compile?

thx

Adam Stoller

The only way to do this would be through CallServer which is asynhronous and relied on calling a CGI script sitting on the server to perform the actual commands you want.

A bigger question might be: Why are you trying to do this via FormAPI?

In your presentation template within an <iw_perl> block,

use iwpt_get_dcr_name, to determine the path to your dcr's

e.g

<iw_perl><![CDATA[
my $srcDir = iwpt_get_dcr_name('dirname');
]]></iw_perl>

I'll assume you are then wanting to use all the dcr's in this folder to produce the output.

using the file path above you need to now return a list of all the dcrs in this folder.

<iw_perl><![CDATA[

my $srcDir = iwpt_get_dcr_name('dirname');

opendir(DIR, $srcDir);
my @dcrList = sort grep {!/^\.+$/} readdir(DIR);
closedir(DIR);

]]></iw_perl>

Now to open each dcr in the array using <iw_load_dcr />

<iw_perl><![CDATA[

foreach $currDCR ( @dcrList ){

]]></iw_perl><iw_load_dcr var='root' file='{iw_value name="$currDCR"/}' mode='dcrlocal'/><iw_perl><![CDATA[

my $title = iwpt_dcr_value('$root.title');

iwpt_output("Title: $title<br />");

}

]]></iw_perl>

and here it is in full.

<?xml version="1.0" encoding="UTF-8" ?>
<iw_pt name="default">
<iw_perl><![CDATA[

my $srcDir = iwpt_get_dcr_name('dirname');

opendir(DIR, $srcDir);
my @dcrList = sort grep {!/^\.+$/} readdir(DIR);
closedir(DIR);

foreach $currDCR ( @dcrList ){

]]></iw_perl><iw_load_dcr var='root' file='{iw_value name="$currDCR"/}' mode='dcrlocal'/><iw_perl><![CDATA[

my $title = iwpt_dcr_value('$root.menuTitle');

iwpt_output("Title: $title<br />");

}

]]></iw_perl>
</iw_pt>

Cheers

I agree - that using the PT makes sense (to me and you at least - though I would have done it without CDATA tags ;-) - however the original question was with regard to doing this in FormAPI... which I don't think makes as much sense.

And here it is without cdata tags

<iw_pt name="default"/>
<iw_perl>

my $srcDir = iwpt_get_dcr_name('dirname');

opendir(DIR, $srcDir);
my @dcrList = sort grep {!/^\.+$/} readdir(DIR);
closedir(DIR);

foreach $currDCR ( @dcrList ){

my $root = iwpt_load_dcr( $currDCR , 'dcrlocal');

my $title = iwpt_dcr_value('$root.menuTitle');

iwpt_output("Title: $title<br />");

}
</iw_perl>

Man....I really appreciate that assistance.

This not only helped with my current issue, but you have explained several things that I found to be completely incomprehensible in what Interwoven refers to as 'the manuals'.

Thanks a bunch,

If you can give me the pages/places that were confusing, and what seemed incorrect/misleading, we can attempt to remedy the errors.
