Hey sorry to top post, but let me try to summarize:
1) You need to make URLs
Ok, perfect you should find that uri_for works in application context
MyApp-uri_for
and that should return a uri::generic object. Hobbs thought it would be easy
to add a util to Catalyst utils that takes a URI::generic and base URL and
returns a real URL. So that should work. Give it a try and let me know?
# MyApp-uri_for
returns an path.
# $c-uri_for
returns nothing useful.
creating kind of a fake request object, as written in the last email, actually
works well for me. also with the latest catalyst version.
i need to generated URLs in the TT2, and there i can't use MyApp-uri_for ...or
i'd need to change all the templates..
soo, thats fine for me as it is.
2) Calling controllers from a script, etc.
I know you probably don't want to hear it (:) ) but I would strive to have
all that business logic elsewhere (not in the controller), so that you can
make this easier.
However if you can't do that we could take a patch to make stash do something
not insane in application context or a plugin to make the stash like the old
stash for people that can't make the leap. How does that sound?
i now changed the code, so i'm not putting data in the stash anymore, works
fine; and maybe is also a better solution. so actually that thing is solved for
me.
anyway, maybe it would be good, to have a plugin that provides the old stash
logic for backward compatibility?
cheers,

Hey again,
You could fake it by giving your instance a request object.
actually in my usecase, i already do fake a request object...
but that does not help either :(
looks like this.

my $uri_path = '/';
my $uri = \$uri_path;

$c-stash-{val} = $val;
my $stash = $c-stash-{val};
print from stash: $stash\n;
I needed to have a request object to have
$c-uri_for();
working for my commandline script to be able to generate real URIs.
Do i need to add further magic while creating request object, so that stash
would also work ? tried to
But tell me more about the use case
the CLI scripts are triggering different actions from Controllers and using
the stash to passaround data from action to action or make some data
available to all actions..
i guess that did not help much ;)

when you do that you don't have a context, its an instance of your
application. Since Catalyst conflates the two this is a common thing to
think :) But you only get a context IF you have a request. So $app-stash
isn't going to work.
I'd be happy to take a patch to do something sorta correct in application
context, but I'd rather help you not use the stash like this. Its probably
going to make sad pandas down the road. That's half the reason I went this
direction (to help move us along toward the application/context split we've
talked about for years and years...)

Hey all,
i'm testing an update to the latest Catalyst version.
the web-application via FCGI works fine, but i do run Catalyst from command

likeuse MyApp;

$c-stash-{val} = $val;
my $stash = $c-stash-{val};
print from stash: $stash\n;
since the upgrade i get the following error:
You requested a stash, but one does not exist at .\site\lib\Catalyst.pm

As i read stash is now a middleware plugin; and is stored in the PSGI?
environment; for sure thats not available when running from CLI.
how to i make the good old stash working if i'm from command line ?
thanks for support,

Re: [Catalyst] Error: You requested a stash, but one does not exist
Johannes, We're going to need a ton more info to help. The likely reason is that about 9 months ago the stash was moved to the middleware layer, which makes it context bound and you are asking for the stash in application scope. We need to know stuff like what version you upgraded from and configuration info, etc. How all the log trace looks up to the error is also needed. Please review the changlog, upgrading and delta pods as well, since that might assist. jnap On Monday, February 23, 2015 3:14 AM, Johannes Kilian jo.kil...@gmx.de wrote: Hi there, I just set up a new virtual machine with WinServer 2012.
