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

[Craig Chant]

Awesome, thanks for demystifying this for me!

# go to a string path ("/foo/bar/gorch")
    # or action object
    if (blessed($command) && $command->isa('Catalyst::Action')) {
        $action = $command;
    }
    else {
        $action = $self->_invoke_as_path( $c, "$command", \@args );
    }

I'm still at a loss why when I was using the wrong syntax, it was working for SplashScreen, but the same syntax for ComplianceUpdates wasn't!

And I still can't find where in the docs/tutorial any of this is explained? (a section and page number would be helpful!)

Regards,

Craig.

True.

It's not :) Catalyst magically converts that for you.

See this:

https://metacpan.org/source/JJNAPIORK/Catalyst-Runtime-5.90051/lib/Catalyst/Dispatcher.pm#L148

It either gets an action object, or it translates the path to an object for you.

I like the string option better. It's cleaner to read. But you should be fine with both.

Cheers,
André
