null-ls fails to find django-stubs (mypy)

[lcfd]

Hi 👋

I'm trying to add mypy typings for Django but null-ls crashes.
If I run mypy in the console (mypy .) it works correctly.

My pyproject.toml

[tool.mypy]
python_version = "3.10"
ignore_missing_imports = true
plugins = ["mypy_django_plugin.main"]

[tool.django-stubs]
django_settings_module = "core.settings.dev"

This is the error:

[null-ls] failed to run generator: ...t/null-ls.nvim/lua/null-ls/helpers/generator_factory.lua:218: error in generator output: pyproject.toml:1:1: error: Error importing plugin "mypy_django_plugin.main": No module named 'mypy_django_plugin' [misc]

Someone has been able to make it work?
Thank you!

I had the same issue. this seems to be working for me:

null_ls.builtins.diagnostics.mypy.with{command={'python', '-m', 'mypy'}}

Wow, let me try it 🥲 I really hope that this will work for me also.
Thank you for the hint!

Developing Django applications has been a weird experience so far.
Also, the Django templates + Tailwind aren't really working together.

Developing Django applications has been a weird experience so far. Also, the Django templates + Tailwind aren't really working together.

Django is a cool tool, but for a really long time I haven't used it on any projects outside of the work and haven't written any front-end code for years.

For Tailwind, it shouldn't be a problem because at the basic level, Django templates are just glorified HTML files.

I hope it fixes for you too.

I still have the error. That's my configuration of null-ls.
Maybe the position I'm using for your snippet is wrong 🤔

    null_ls.setup({
        sources = {
            null_ls.builtins.formatting.stylua,
            null_ls.builtins.formatting.black,
            null_ls.builtins.formatting.djlint,
            null_ls.builtins.formatting.prettier,
            null_ls.builtins.code_actions.eslint_d,
            null_ls.builtins.diagnostics.flake8,
            null_ls.builtins.diagnostics.mypy
        },
        debug = true
    })

    mason_null_ls.setup({
        ensure_installed = {
            "stylua",
            "black",
            "eslint_d",
            "prettier",
            "djlint",
            "flake8",
            "mypy"
        },
        automatic_installation = true
    })

    null_ls.builtins.diagnostics.mypy.with {
        command = {
            'python',
            '-m',
            'mypy'
        }
    }

It's wrong. The line I send should be in the sources table.

null_ls.setup({
        sources = {
            null_ls.builtins.formatting.stylua,
            null_ls.builtins.formatting.black,
            null_ls.builtins.formatting.djlint,
            null_ls.builtins.formatting.prettier,
            null_ls.builtins.code_actions.eslint_d,
            null_ls.builtins.diagnostics.flake8,
            null_ls.builtins.diagnostics.mypy.with{command={'python', '-m', 'mypy'}}
        },
        debug = true
    })
