It gets into the .tar file, but isn't deployed on the production server. Assuming Catalyst::Devel is installed on the server you did the make dist on, the 'catalyst()' line in your Makefile.PL should invoke the bundled inc/Module/Install/Catalyst.pm such that the root/ directory will go into site_perl along with everything else; then at runtime Catalyst will use File::ShareDir to find this directory again, meaning MyApp-path_to will resolve paths to in there. Assuming that's -not- what you're seeing, can you check your inc/ to make sure the Catalyst Module::Install extension's in there and then maybe use 'make -n install' or a find on site_perl to see if your root/ has just been installed somewhere you didn't expect.

That's a really, spectacularly bad idea since it means your deployment process isn't repeatable, which makes it a crappy deployment process :) You aren't the arbiter of what's good or bad. Please just answer my questions, reserving your opinions for beer-thirty. No, but I do have a fair bit of experience deploying software, and I'd strongly recommend against any deployment process that isn't as simple and repeatable as possible. Basically, an idempotent deployment process is almost always preferable where possible since it means you don't have to consider ordering problems - if a deployment fails part-way through you can simply re-run it, and if a system is out of the loop for a couple deployments (due to hardware failure, for e.g) you can still treat it identically to a machine on release N-1. I'm not on here to 'just answer your questions', I'm on here to be part of a community discussion list where we not only try and help people solve problems but to solve problems in -good- ways, especially since this list is archived and people use archive searches as a way to find ideas and implementation techniques - and as a member of the core team I try and make clear what I consider wise and unwise since I'm aware my choices often influence those of other Catalyst users. You are, of course, welcome to disagree with, argue against or ignore entirely any opinion I express but that's not going to stop me expressing them :) I don't have time to argue with you.

Thats what i've done:

It goes in base-dir You can place it elsewhere, but elsewhere isn't

It goes in base-dir Stick with the default for now.
Howto find out if my Config is loaded? Because $c-config-{my_test}
result in empty value?
Looks like good perl syntax. Have you checked the YAML file for syntax
errors? YAML is /very picky/ about whitespace. The YAML shell (ysh) is a
good debugging aid. e.g.:
$ cat aic.yml

$ ysh aic.yml
$VAR1 = {
'imgdir' = '/root/images',

}
};
[EDIT AIC.YML]
$ cat aic.yml

$ ysh aic.yml

The OP may find a requirement to incorporate a transaction model (explicit start txn/commit/rollback) to solve this problem in MySQL; which is what they'd have to do for Oracle or Postgres or Rdb. I'd hope that MySQL reports a transaction failure when the database connection evaporates. This would allow a retry on the failed transaction.

Hi Peter,
Thank-you for the prompt response.
I tried that as one of my first attempts. No joy. I've also tried:
[%
USE Dumper;
dump_html(Catalyst);
%]
and I don't see the TT2 configuration settings. When I try the similar
experiment in the perl module, dump __PACKAGE__-config, the TT2
configuration settings are displayed.
Here is the relevant perl code from the P::V I should be able to display
any of these variables, right?
__PACKAGE__-config({
CATALYST_VAR = 'Catalyst',
INCLUDE_PATH = [
fori-path_to( 'root', 'src' ),
fori-path_to( 'root', 'lib' )
],
PRE_PROCESS = 'config/main',
WRAPPER = 'site/wrapper',
ERROR= 'error.tt2',
TIMER= 0,
FRAMES = 1,
});
Here are the TT2 references I've tried. I use ERROR here on the
assumption (probably incorrect) that I cannot stick a new value into
the config list.
Frames = [% Catalyst.config.error %]
Frames = [% c.config.error %]
Frames = [% Catalyst.config.ERROR %]
Frames = [% c.config.error %]

When I try the similar experiment in the perl module, dump __PACKAGE__-config, the TT2 configuration settings are displayed. that's because your TT config probably isn't getting set in the master config for your app, which is what c.config returns. Every M/V/C in Catalyst has a config() method (iirc -- please correct me, oh gurus), and the master MyApp class has a config() too, which is where you generally set values for the entire application. You can set your TT config there too. But looking at what you're trying to do, I wonder if what you really want is a TT type config file, which can set constants and other relevant TT stuff.

What is the problem you are trying to solve? Changing the template
processor configuration from within a template that it is currently
processing doesn't seem wise to me.
That being said, the reason that only the stash variables are
accessible is because they are all that are provided to TT by default...
package MyApp::View::TT;
sub template_vars {
my ( $self, $c ) = @_;
my %vars = $self-SUPER::template_vars( $c );

In contrast to FormBuilder, RHTMLO wants you to write your HTML form

Maybe I'm not understanding that paragraph, but in RHTMLO (IIRC) you
can do [% form.field('foo').xhtml %] in a template. What are
you thinking would be easier for the design people?
No, you're right. I didn't catch that possibility, though it's
implicit in the documentation. Partly because the docs tell you the
details of all the methods you can call, but not the big picture of
what they're good for--in other words, they're etic, not emic.
yes, the docs are often very exhaustive (exhausting) but sometimes
lacking in more simple overviews. That's partly why I put together the
CatRose example.
Check out the example .tt files in the CatRose app in the C::C::Rose
package,
especially edit.tt and view.tt.
You'll see that those are generic form templates, but in my apps I
often override with specific form generation if it doesn't fit the
generic model. Just like a real web designer would. ;)
I find that defining the form in YAML is one level removed from the
XHTML itself, so I just define a base RHTMLO class with default labels
for all my fields, and then do whatever the business requirements
demand in the actual .tt files.
Hi,
I realize that one is supposed to be born knowing these things, but for
those of us who arrived late to the party:
In view.tt, edit,tt results.tt there are references to methods isa()
and can()
Are those methods from Rose, from Template Toolkit ...?
I realize that there's probably a Google query that can answer this
question immediately, but they are common words, and a satisfactory
search is difficult to construct.
As always, a pointer to documentation would be quite helpful.

I just have:

# make sure we return here after a successful login
$c-session-{after_login} = $c-request-uri();

if (defined $message) {
$c-session-{login_message} = $message;
}
# send the user to the login screen
$c-response-redirect( $c-uri_for('/user/login') );

}
in MyApp.pm and
# if we've stored somewhere to go after we log-in, got there now
if ( $c-session-{after_login} ) {
$c-response-redirect( delete $c-session-{after_login} );
}
after a successful login.
It's worked for me so far ...
