Use uv to manage dependencies

[fyliu]

Fixes #178
Fixes #183

What changes did you make?

• Added missing doc item for ERD generating script
• Set up uv to manage dependencies + docs
• Replace pip with uv for faster installs
• Set up docker buildkit cache mounts for faster image rebuilds + docs

Why did you make the changes (we will use this info to test)?

• We needed a way to update dependencies

How to test

• verify the update script works ./scripts/update-dependencies.sh
• verify the buildrun script works ./scripts/buildrun.sh
• verify the erd script works ./scripts/erd.sh
• verify all tests still pass ./scripts/test.sh

Rebased to latest main and force pushed

Found a problem when running where nc is required. Will undo those changes and re-evaluate the apt requirements later.

@fyliu these are my observations while testing

• ./scripts/update-dependencies.sh can't be found in the branch

• ./scripts/buildrun.sh works great, as desired uv gets downloaded and we are using the djaongo version of 4.2.11

• ./scripts.test.sh also works good as well

• ./scripts/erd.sh I'm not sure what it does except, it should show and ERD diagram, but all I got as an output is

  >> ./scripts/erd.sh      
  + docker-compose exec web python manage.py graph_models --pydot -a -g -o erd.png

@fyliu Thanks for working on the changes, the script update-dependencies.sh is available and on execution make changes to requirement.txt by updating the versions.

I'm still not sure on the ./scripts/erd.sh, can't find an end.png

I'm still not sure on the ./scripts/erd.sh, can't find an end.png

@freaky4wrld It should be in app/erd.png

❯ file app/erd.png
app/erd.png: PNG image data, 5113 x 1379, 8-bit/color RGBA, non-interlaced

I also amended the erd commit with the location of the generated image.

@fyliu thanks for making the changes, here is my observations as per the new changes done:

• update-dependencies.sh produces updated version of tools in requirements.txt
• build run.sh runs successfully
• erd.sh produces erd.png in the app directory
• test.sh successfully checks for the test provided

PR approved!!!! Thanks for your contribution, really appreciate all your efforts :)
