[Catalyst] Can't detach from root / create action object

[Craig Chant]

No the documentation isn't clear, if I could understand it I wouldn’t be asking this question.

What is $action ?  And yes I've looked at  the manual.

Chapter 3 when you search for 'detach' states..

NOTE: If you use the default template technique, you will not be able to use either the $c->forward or the $c->detach mechanisms (these are discussed in Chapter 2 and Chapter 9 of the Tutorial).

So I go back to chapter 2 and search for detach and get zero results the same when I search chapter 9?

Not sure why you seem to think the tutorial is clear, when I seem to be going round in circles?

You should tell us what you want to achieve.

"I want to pass an action to detach()" is not a proper problem description.


The documentation is pretty clear on what is expected.
https://metacpan.org/pod/Catalyst#c-detach-action-arguments

$c->detach( $action [, \@arguments ] )
$c->detach( $class, $method, [, \@arguments ] )
$c->detach()

Have you checked the Catalyst Tutorial. It should provide examples for detach() There is also the test suite which you can grep for detach.
