[Petal] Implementation question

[William McKee]

Hi folks,

Looking for some advice. I'm building a template that will display a list 
of names and phone numbers in a series of rows. If the users selects one 
of the rows (identified by an id), I want to make that row appear in a 
form so that the user can update the information. So, I need to have a way 
to check whether the current row show be put into a form or displayed 
normally.

My initial thoughts are to check whether the id given to the script is the 
same as the id of the current row. However, Petal doesn't support this 
kind of evaluation (yet?). My next thought was to add a new element to my 
list which could be evaluated true/false. Ok, that sounds good. How can I 
do it?

Option A:
	In my Perl script, loop over each element, test whether its id equals the 
id passed to the script and set a value.

Option B:
	Write an anonymous subroutine that compares the value of the id passed to 
the script with the id of the current row (as passed to the subroutine by 
the template). Will this become a closure (is that the right term)? Will 
the values get updated as I continue to use the script (I ask because I 
know that Petal is caching these templates)? I have not tested this idea.

So my question for you, if you're still with me, is what's the most 
efficient way to do this? Option A or Option B?

Thanks,
William

PS: Here's what the template would theoretically look like if I used 
Option A (I ran into the bug I submitted when trying to actually use this 
format):

<?petal:repeat="rater raters"?>
<tr petal:if="false: rater.edit">
	<td petal:content="rater.first_name">First Name</td>
	<td petal:content="rater.last_name">Last Name</td>
	<td petal:content="rater.relation">Relation</td>
	<td petal:content="rater.phone">Phone</td>
	<td petal:content="rater.email">Email</td>
</tr>
<tr petal:if="true: rater.edit">
	<td><input petal:attr="name string:first_name" petal:attr="value 
rater.first_name" type="string" size="15" /></td>
	<td><input petal:attr="name string:last_name" petal:attr="value 
rater.last_name" type="string" size="15" /></td>
	<td><input petal:attr="name string:relation" petal:attr="value 
rater.relation" type="string" size="18" /></td>
	<td><input petal:attr="name string:phone" petal:attr="value rater.phone" 
type="string" size="11" /></td>
	<td><input petal:attr="name string:email" petal:attr="value rater.email" 
type="string" size="35" /></td>
</tr>
<?end?>
