How can I resolve the problem "Import "django.http" could not be resolved from source VSCode does not allow the import of the django library added to the docker container.

i got this error when i debugging. a debug stop at line in the manage.py. the error message is "Exception has occurred: OperationalError
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
psycopg2.OperationalError: could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?


The above exception was the direct cause of the following exception:

File "d:\django projects\recipe-app-api\app\manage.py", line 18, in main

File "d:\django projects\recipe-app-api\app\manage.py", line 22, in <module>
main()
could not connect to server: No such file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?"

Doesn't work for me, the debug console turns orange for like a second and stops. I wonder because I've followed all the steps

I have issue when run debug: timed out waiting for launcher to connect

[AllPsychBouldering]

This seems to fail when I'm already using postgres for my project, is there any way to fix this error:

connection to server on socket failed: No such file or directory
Is the server running locally and accepting connections on that socket?

When I check docker ps my database is in fact running on 5432 and healthy. Thanks!

Great video, thank you!
I'm using PyCharm myself, but I picked up a couple of interesting Docker nuggets from this like the user part.

I am getting the error "Debug Adapter Executable not provided" error after executing docker command. App doesn't execute in debug mode. Please help.

Helped so much on doing the same with odoo tnx

[rodionbykov]

Not seem to use docker-compose debug though, but mentioning it makes confusion.

[markera]

I have a problem:
1. Added a service "db" in docker-compose.yml with postgres image.
2. When referencing the "db" in django's settings.py, the vscode debug shows error, where it says there is no "db" host.
Do you know what it can be?

When I tried applying this to my project I got an error in VSCode 'Invalid message: "pythonPath" is not valid if "python" is specified'.

I decided to instead clone your repository to try and play about with debugging with your exact code. However, I get the same error message there too?

Any help would be great!

[alexblack]

Thanks for the video
I need to learn docker

[treerhym]

did not understand, when you click on run and stat debugging how visual studio knows where to connect ?
how it knows that I have to connect to container end point instead of starting it locally?

[eduardolucas]

Awesome! Exactly what I was looking for...

Hello, can you tell me if it is possible to work on vs code using Django modules auto-import? I assume that by entering, for example, LoginView and pressing Ctrl+Space, a suggestion will appear to import this class from internal Django modules, if, for example, I do not know where exactly in which module it is located. Please help me..

Great tutorial
I am so glad to discover this channel

[BruceCichowlas]

This is a great tutorial and the blog version is great, too. This is about the 5th of similar tutorials that i've tried. Perhaps most of them ran correctly at some time, but I couldn't follow them through to completion now. Of course, I might have misunderstood something or done something wrong, too.

But what I was really looking for was a tutorial like this using PyCharm and targeting Virtual Box. I couldn't get any of those to work for me, but I am hoping what I learned here will transfer. I can't do much about the Virtual Box requirement, but I am okay with using Code if that is the easier path.

It takes me 30 seconds to enter the debugging mode inside the contain, is there a way to speedup the startup? Thanks

Hi Mark!
I completed your course of Django Advance in udemy
How to make that exiting project to run in VS code debug mode?
and I found issue that I have to user from app.core.models import Recipe
to get auto suggestion from VS code which lead to give error in project so I need to remove app. from it how to solve that also

[damianofranco]

Thank you very usefull! but it doesn't reload the code when modified as it happen outside the docker. Is there a way to get the code reloaded during debugging?
