first time user of Slim4 framework and first time even trying to use a DI. Slim4 uses PHP-DI and i'm having a hell of a time figuring out how to use it. It seems to only inject SOME of the dependencies while ignoring others. How do i debug this or troubleshoot it? I've run "composer dump-autoload" to no avail, it has the classes mapped correctly. Everything is typehinted, and explicit "use blah/blah" exist as well. any help would be appreciated

So i included the routes.php which is the next step that would run, which you saw in the bootstrap.php earlier. But unless i manually put those includes (which are commented out) it gives me the above error message. But you can see it's not throwing errors for Slim\App or anything else, but it does for \App\Action\AccountReadAction
I don't know Slim, but to me this looks more like an autoload issue than a DI issue. Are you sure you have an autoloader somewhere that's able to handle
\App classes? Otherwise if it follows PSR-4 convention (which it should) you can add it to your composer.json like so: https://getcomposer.org/doc/04-schema.md#psr-4
{
"require": {
"php": ">=7.1",
"ext-json": "*",
"monolog/monolog": "^2.0",
"php-di/php-di": "^6.0",
"selective/config": "^0.1.1",
"slim/http": "^0.8.0",
"slim/psr7": "^0.6.0",
"slim/slim": "4.*"
},
"require-dev": {
"phpunit/phpunit": "8"
},
"autoload": {
"psr-4": {
"App\\": "public/app/"
}
}
}
Sorry I won't be able to help you more for today (you know, Xmas and stuff) but I'll try to come back in a few days. In the meantime, try to use the debugger to trace how files are (auto)loaded and classes are resolved, you might figure out what's wrong more easily.
oh and yes, you are correct, that is the path of the file
The learning curve is just a bit steep
i have to say it's really tempting to just say screw it and just manually put the require lines in and be done with it
@gmariani It looks like an PSR-4 autoloader issue. Make sure that you defined the correct namespaces and paths in your composer.json file. Linux is case sensitive. For example if you have a namespace
App\Action, then your directory should be named like this: src/Action/ and not src/action/.
Hello :wave: when using the autowiring to load classes, if the class can not be instantiated because of an exception the container just returns null, is this behaviour intended (I don't know if I've changed something) and is there any way I can make these exceptions get thrown out of the container so I can handle them myself?
Hi. I have this problem, when I upload my project to a host this error activates me: Fatal error: Not captured DI \ NotFoundException: No entry or class was found for 'App \ Controllers \ AuthController' in /home/vrfctuqw/myhonsting.com/ vendor /php-di/php-di/src/Container.php:135 Stack tracking: # 0 /home/vrfctuqw/myhosting.com/vendor/php-di/php-di/src/CompiledContainer.php(64) : DI \ Container-> get ('App \ Controllers ...') # 1 /home/vrfctuqw/myhosting.com/public/index.php(474): DI \ CompiledContainer-> get ('App \ \ Controllers ...

Locally it works correctly, but in hosting I present this. I would like you to help me please
Hi I have used "mnapoli/php-di": "~4.0", "container-interop/container-interop": "^1.1", for my application and now im moving to php 7 with "php-di/php-di": "6.0.11", "psr/container": "^1.0.0", I'm getting "Entry "Idfix\Contracts\RegistryInterface" cannot be resolved: the class is not instantiable Full definition: Object ( class = #NOT INSTANTIABLE# Idfix\Contracts\RegistryInterface lazy = false )" this issue please advice
Hello! So, after doing
composer update I get a notice that the package jeremeamia/superclosure is abandoned and php-di seems to require/depend on this package. Any solutions to this problem especially that the recommendation is using opis/closure and it's not advisable to edit composer.lock directly??
Sorry, not read RTFM :)
Closed.
Thanks.
Can anyone point me in the right direction of how to debug that? @mnapoli ?
The stack trace isn't exactly helpful
I previously had an error because I was using
use ($var) in a closure, but took those out
What could be causing that?
