A newbie question
greetings -
Let me start with a confession that I'm a newbie to perl and
modules although I've got truckloads of experience on Windows
ASP side. Anyway, I need a bit of wizdom on how to use
packages with Apache::ASP. Please read on.
In my httpd.conf I have
PerlSetVar UseStrict 1
PerlSetVar UniquePackages 0
then I have a script - called "Login.pl" - that goes like this:
<html>
<%
$Response->Include($Server->MapPath("/pls/Common/consts.pl"),"");
$Response->Write(blabla()."<BR>");
$Response->Write("A_VARIABLE=".$A_VARIABLE."<BR>");
%>
</html>
The contents of /pls/Common/consts.pl is
<%
our $A_VARIABLE = "whatever";
sub blabla {
"blabla";
}
%>
Now, when I execute Login.pl, I get this error in errors_log
"Variable "$A_VARIABLE" is not imported at Login.pl line 5."
I would like to get rid of this error without having
"PerlSetVar UseStrict 0" in httpd.conf. But how? Using
"no strict" in Login.pls does not help, and all perl
keywords "local", "my", and "our" are scoped to the current
file, eval or block. Using no keyword at all to declare
$A_VARIABLE gives the same error, but now in file consts.pl.
Should I really make a separate Perl package out of consts.pl
and then import the variables from package consts into Login.pl?
This seems a little absurd because per "PerlSetVar UniquePackages
0" in httpd.conf, both Login.pl and consts.pl are in the same
package, and there should be a simple way for any script in
the package to use variables declared in other scripts of the
package. Or am I wrong? Please let me know.
Thank you in advance
Constantine

Sure, the more templating engines the better! :-)
The only caveat here is that I definitely don't have the time to implement this,
and besides, I don't know ASP. Andy Wardley sent me a big patch to enable
Template Toolkit support, so if somebody wants to take a whack at this and send
me a corresponding patch, I will gladly add it. Look near the bottom of
render(), where there are some if/elsif/else statements looking for the type of
template specified. This shouldn't be too hard to slot in there.

Actually, using asp includes for the templating sounds great... I
haven't looked at the code, but I wouldn't think it would be that hard
to add. It'd be great not to have to learn yet another pseudo-language
to accomplish this (Template::Toolkit or HTML::Toolkit) when Apache::ASP
is something I already know! I'll start looking at the FormBuilder
hooks, and see how involved it is - don't know if I have the time to
actually implement it, but it's a great idea.
I'm cc'ing Nate on this too, see what he thinks.

Getting more off topic now, but thought I'd mention about FormBuilder...
I find CGI::FormBuilder really useful and have come to prefer it to
use CGI methods or HTML code directly.
To use it effectively in Apache::ASP several settings are useful:
javascript => 0,
header => 0,
Although the javascript one can sometimes be useful, I found it made
life more difficult than it was worth.
Also, with multistage forms (e.g. purchaser details on page 1,
product details page 2, card details page 3 etc) I came up with a few
tricks which I can post if anyone is interested.
Most of the time I used FormBuilder's inbuilt $form->render() method
because it was easier than doing a template; it dawned on me that it
would make sense to add another template method for FormBuilder,
something like:
$form->render( ASPInclude => 'inc_user_details.asp' )
or whatever, and instead of HTML::Template variables,
CGI::FormBuilder could just supply a hashref to the include file
allowing stuff like:
[inc_user_details.asp]
<p>User Name: <%= $cgiform->{'field_user_name'} %>
etc
This isn't existing functionality in FormBuilder, but if anyone else
thinks its a worthy idea it could be recommended to the author.

Looks like CGI::FormBuilder/Template::Toolkit combined with
DBIx::Recordset is probably my best bet. I knew about them
individually, but for some reason just didn't think to use them in
combination to achieve 95% of what I wanted... I'll still have to code,
but if I didn't have to code anything, what fun would it be! And if I
ever do find anything better I'll be sure to pass it along. FormBuilder
is pretty impressive looking so far - wish I head read over it more
thoroughly before asking the question. Though it was a good exercise, I
think.
Thanks for the virtual whack upside the head. (doh!)

I have always rolled by own application by application, but my
apps have always had to be pretty tight to the database for
high performance with mixed OLAP/OLTP environments.
If you feel that RAD does not have to be GUI RAD, I might look at these:
CGI::FormBuilder ( promises 4x code reduction )
DBIx::XHTML_Table
If you want something closer do the database, and don't mind doing your
own HTML, check out:
DBIx::Recordset
Alzabo
They at least abstract DBI slightly away from you.

phpLens looks nice. You you want something that is more of a CMS in
perl, you can try Bricolage or Mason:
http://bricolage.thepirtgroup.com/

Sorry, I don't think any of these quite hit it on the head for you, but
I thought I'd try! Best of luck, and if you find anything interesting
please share it with the rest of us, as it seems to be a fairly common

Its a good question... I haven't seen anything myself which suprised
me. It would have been really handy for me too. With DBI/DBD I
would've thought a set of classes could be designed to make it
easy(er) to browse and edit rows.
e.g.
<% # browse_books.asp #
use DBD::Forms;
### prepare a Forms RowBrowser - note that the database
### handle could be oracle, mysql, etc...
my $browser = new DBD::Forms::RowBrowser( $dbh );
### prepare the browser to look at rows from the book table
$browser->prepare(
Table => 'Book',
SelectColumns => [qw/ title isbn authorlist year/],
SortColumn => 'title',
RowsPerPage => 10
);
### format the title column as a link to book details
$browser->format(
Column => 'title',
FormatSub => sub {
my ( $title, $hashRef ) = @_;
my $isbn = $hashref->{ 'isbn' };
my $url = $Server->URL( 'details.asp', { isbn => $isbn });
return "<a href=\"$url\">$title</a>";
},
CellCSS => 'data',
);
### print 10 rows from the table... could use default layout or
### templates (a'la CGI::FormBuilder)
print $browseRows->printHTML( Template => 'table_template.html' );
%>
I had a quick go at it when I first started the current project but
the deadlines made it very hard to spend the time needed to keep it
generic and intuitive. I had to go back to doing the app-specific
version :(

This isn't specific to Apache:ASP, but I've seen a lot of good advice
here, and hopefully someone has already been through this.
I was just wondering if anyone had used/knows of anything for perl
similar to phpLens. I haven't actually used it, but it looks pretty
impressive. I'd prefer to stick with perl, though. I've searched
through CPAN, and on google, and haven't found anything obviously like
phpLens for perl, but there's a lot out there and I may have just missed
it. The closest I think I've seen so far is DBIx::HTMLView, but it's
only for mySQL and mSQL (needs some extra coding for other DBD drivers -
I think).
Basically, I'm just looking for some tools for generating things like
master/detail editing forms and backends. I'm not looking to avoid
coding entirely, just for something to make life easier. I don't need
all the bells and whistles of phpLens - though they would be nice. And
I need to be able to make updates - simply displaying data is fairly
trivial, and I wouldn't need to ask for tools to do that - they are a
dime a dozen (though not all of the same quality!).
My alternative will probably be to use Oracle Forms (since we have a
site license for nearly every Oracle product for internal use only), but
I really want stick to perl if I can - mostly so I'm not tied to
Oracle's RDBMS in the future. If you've read this far thanks. If you
have suggestions, thanks a lot!
I suppose if there's nothing like phpLens, I'll either have to use
Forms, roll my own perlLens, or switch to PHP and buy phpLens.
Thanks again,
Jim
