Implem call to NOW()

[Nirsu]

Hello o/
This is my first open source contribution.
I wanted to implement a function to call the NOW() function in postgres.

Problem:
Try to understand how to have createdAt with a default value

Resolution:
Create this function in my server, but could be in the lib

Thank you, and congratulations on your first contribution!

The change looks good to me, but we need a test to verify that it keeps working. You could add one to this file. Tests there have access to the eval function which takes an expression and runs it on the postgres server. So you could write a test calling await eval(now()) and then verifies that the time we get back is close to DateTime.now() in Dart.

Thanks for the message,

I've tried to implement tests but I can't run the tests locally
I'm in the drift_postgres folder, run the docker run -p 5432:5432 -e POSTGRES_USER=postgres -e POSTGRES_PASSWORD=postgres postgres command in one terminal and dart test -j 1 in another.

But I got this error on all the tests

Hm I've never considered that this would be broken on Windows, sorry. I don't have a Windows machine at hand, but can you check whether replacing localhost with the IP as shown here does anything to fix this?

But also could this be a firewall or an outdated Docker desktop version? A friend using Windows tell me he can access containers via localhost just fine.

I've tried, I don't have DockerNAT when I use ipconfig
Thanks for the advice, I'll try to see and get back to you as soon as possible.

Did you have a chance to revisit this yet? I'm also happy to help with the test if you can't get the configuration to work locally.

Hey,
I've managed to run the test locally but I'd love some help with the test :)
Because unfortunately eval(now()) throws me an error on the type
