Thanks! This is lookng good. I'm updating Django versions in #189 so we properly test this on < 3.2 (via 2.2.*) and 3.2+ (via 3.2.*) on CI.

[syth0le]

Great! That's would be a nice idea to test it on different django versions on CI

[florimondmanca]

@syth0le The versions updates got merged, feel free to rebase to see how this behaves against 2.2 and 3.2 :-)

@florimondmanca
I think that all checks have been passed, but to be honest I dont know what to do with tests coverage (for 2 files). is it normal?
Or do you need to more than 95 percent of tests coverage for each file?

[florimondmanca]

Thanks!

I found recently that you can add a global .gitignore config to your machine like this:

touch ~/.gitignore
git config --global core.excludesfile ~/.gitignore

Helps prevent conflicts with developer dotfiles/dotdirs like these :) No problem including this though.

@syth0le I think codecov requires not reducing the coverage by default. We do have a code branch that's not run here (the one that's for < 3.2), and so the coverage decreased slightly. Not a problem, we can merge. I might look at if there's a way to have Codecov not fail a build for this reason…
