Debug Netbox-qrcode Plugin (Docker-Compose)

[LHBL2003]

I would like to help with the development of Netbox plugins like Netbox-qrcode. I myself come more from C# .Net and Visual Studio, but I would like to be able to debug and thus observe the qrcode plugin in Visual Studio code.

I get the docker-compose container started, but I don't have the experience on how to properly configure the debugging files (launch.json and tasks.json). I've tried a few things but always get error messages in the specified *.py files. Does anyone have experience with this and know what I have to select in vscode under Run --> Add Confiuration or how I have to configure the launch.json and tasks.json? Do I perhaps also need a docker-compose.debug.yml?

My Setup:
Operating system: Ubuntu
Visual Studio Code (mit Docker Extension und Python)
Github Desktop

My current process:

• GitHub Projects heruntergeladen: https://github.com/netbox-community/netbox-qrcode.git

• docker-compose.yml --> rechtsklick --> Compose UP
  

• vscode --> Docker --> Containers --> Folder Develop -->Develop-netbox --> View Logs --> Waiting for Netbox to start
  

• Create Super User via develop-netbox Container --> Attach Shell

cd /opt/netbox/netbox
python3 manage.py createsuperuser

• Login Netbox: http://localhost:8000/ (with createsuperuser)

Create some basic elements. Just click on Add and insert something into the mandatory fields. e.g. Test
For:
http://localhost:8000/dcim/sites/
http://localhost:8000/dcim/device-roles/
http://localhost:8000/dcim/device-types/

• Create a Dummy Device (So that you can see the Netbox-qrcode plugin.)
  

#To create the debugging configuration files I had done the following:

• vscode --> Menu --> Run --> Add Configuration ... --> "Docker: Debug in Container" --> Python: Django --> any py file --> 8000 (Port)--> include Docker Compose File: NO

• .dockerignore_ renamed to .dockerignore_ because otherwise it prevents me from starting the debugging.

• launch.json changed

{
    "configurations": [
        {
            "name": "Docker: Python - Django",
            "type": "docker",
            "request": "launch",
            "preLaunchTask": "docker-run: debug",
            "python": {
                "pathMappings": [
                    {
                        "localRoot": "${workspaceFolder}/netbox_qrcode",
                        "remoteRoot": "netbox_qrcode"
                    }
                ],
                "projectType": "django"
            }
        }
    ]
}

tasks.json changed

{
	"version": "2.0.0",
	"tasks": [
		{
			"type": "docker-build",
			"label": "docker-build",
			"platform": "python",
			"dockerBuild": {
				"tag": "netboxqrcode:latest",
				"dockerfile": "${workspaceFolder}/develop/Dockerfile",
				"context": "${workspaceFolder}",
				"pull": true
			}
		},
		{
			"type": "docker-run",
			"label": "docker-run: debug",
			"dependsOn": [
				"docker-build"
			],
			"python": {
				"args": [
					"runserver",
					"0.0.0.0:8000",
					"--nothreading",
					"--noreload"
				],
				"file": "/opt/netbox/netbox/netbox/urls.py"
			}
		}
	]
}

Info: I found the plugin here "/source/netbox_qrcode"

But it doesn't matter whether I take a py file from the qrcode folder or one from the Netbox folder. I can't get into a clean debug mode without an error message.

I hope someone has the experience how to debug something like this, so that I can call the device page and debug the qrcode utilitys.py file. Many thanks for any help. I have no idea what else I could do. I would like to understand it so that I can help better in the future.

Either I'm doing something wrong or I don't know which py file to start with.

No idea?

Is there no one who develops a Blugin via Docker Compose?
I've already tried a few constellations here too. But unfortunately, the creator of this plugin and the Docker Compost construct does not meet. :(

It works quite well with the Cocker Compose. But I get it started in debug because something is always missing...

I can't believe I got it :D
I'll create another empty VM and set everything up step by step so that others can also benefit from it.
I will then report here:
