Much of the Django code you remember is from 2.x–4.x,\nand Django has removed a lot since then: `url()`, `ugettext`, `force_text`, `is_ajax()`, `index_together`,\n`NullBooleanField`, and in 6.0 and 6.1 `CheckConstraint(check=)`, positional `Model.save()` arguments and more.\n\n## Version facts\n- Check the pin first: `uv run python -m django --version`.\n- Django 6.0 needs Python 3.12+, defaults `DEFAULT_AUTO_FIELD` to `BigAutoField`, and assumes `https` in\n `forms.URLField`. It also adds built-in CSP support, template partials and a background Tasks framework (`django.tasks`).\n- Django 6.1 removes the 5.2 deprecations, for example `finders.find(all=)` → `find_all=`, and\n `ArrayAgg(ordering=)` → `order_by=`. `login(request, None)` no longer falls back to `request.user`.\n- Django 6.1 deprecates the `EMAIL_*` connection settings: configure mail in `MAILERS`\n (`{\"default\": {\"BACKEND\": ..., \"OPTIONS\": {...}}}`), in the same style as `DATABASES` and `CACHES`.\n- Django 6.1 adds fetch modes: `Order.objects.fetch_mode(models.FETCH_RAISE)` turns a lazy load (an N+1) into an\n error, and `FETCH_PEERS` loads the field for every instance from the same query at once.\n- Deprecation warnings for the next removals are `RemovedInDjango70Warning`, then `RemovedInDjango2028Warning`\n (the class name says which release removes them).\n- If you're not sure an API exists, check the docs for this version (https://docs.djangoproject.com/en/6.1/) and\n the release notes, not old tutorials.\n\n## Rules\n- Write Django 6 code only. The `django-6-guard` skill has the full table. The common ones are: `path()` /\n `re_path()`, `gettext_lazy`, `force_str`, `CheckConstraint(condition=)`, `save(update_fields=[...])` with keywords,\n `Meta.indexes`, `BooleanField(null=True)`, `{% load static %}`, `datetime.UTC` / `zoneinfo`.\n- Run `django-upgrade --target-version 6.1` on files you change. It rewrites many old forms safely.\n- Every model change comes with a migration made by `makemigrations`. Never write or edit migrations by hand to \"fix\" a check.\n- For simple background jobs, look at `django.tasks` before adding Celery, and ask the human.\n- Don't change the Django version or `DEFAULT_AUTO_FIELD` in an existing project without asking.\n\n## Before you say \"done\"\n1. Run the `django-6-guard` scanner on the apps and templates you touched. It must report `0 error(s)`.\n2. Run `django-upgrade --check --target-version 6.1` on the changed `.py` files. It must report nothing to rewrite.\n3. Run `python manage.py check` and `python manage.py makemigrations --check --dry-run`.\n4. Run the tests with next-version deprecations as errors:\n `python -W error::django.utils.deprecation.RemovedInDjango70Warning -W error::django.utils.deprecation.RemovedInDjango2028Warning manage.py test`.\n" }, { "path": "CLAUDE.md", "role": "adapter", "description": "Imports AGENTS.md for Claude Code.", "skill": null, "agent": "claude-code", "install_to": { "claude-code": "CLAUDE.md", "codex": null, "cursor": null, "gemini-cli": null, "antigravity-cli": null, "copilot": null }, "raw_url": "https://setupbay.com/raw/django-6-upgrade-guard/1.0.0/CLAUDE.md", "raw_latest_url": "https://setupbay.com/raw/django-6-upgrade-guard/latest/CLAUDE.md", "bytes": 393, "lang": "markdown", "content": "# CLAUDE.md\n\n@AGENTS.md\n\n## Claude Code notes\n\n- Skills from this loadout live in `.claude/skills/`: `django-6-guard`.

All of those are gone. Django 6.0 and 6.1 removed more, including\n`CheckConstraint(check=)`, positional `Model.save()` arguments, `format_html()` without arguments,\n`finders.find(all=)` and the Postgres aggregates' `ordering=`. This skill finds them, lets `django-upgrade` rewrite\nwhat it can, then lets Django check the rest.\n\n## 1. Confirm the version\n- `uv run python -m django --version` should print `6.1.x`. If it doesn't, ask before changing code for a different version.\n\n## 2. Scan\n```bash\npython3 .agents/skills/django-6-guard/scripts/django6_guard.py shop templates\n```\n(Use the path the skill was installed to: `.claude/skills/...` for Claude Code, `.agents/skills/...` for the others.)\n\n- Every `error` line is a removed API. Fix it with the replacement on the line. `references/removals.md` says which\n release removed each one.\n- `warn` lines are behaviour changes to decide on: `login(request, None)`, an explicit `AutoField` default,\n positional mail arguments, `EMAIL_*` settings that now belong in `MAILERS`, or Celery added where `django.tasks` might do.\n\n## 3. Let django-upgrade rewrite what it safely can\n```bash\nuvx --from django-upgrade==1.33.0 django-upgrade --target-version 6.1 shop/*.py\n```\n- Then run it again with `--check`. It must print nothing. Review its diff like any other change.\n- It doesn't cover everything the scanner does (for example `NullBooleanField` or `CheckConstraint(check=)`),\n so run both.\n\n## 4. Let Django check it\n```bash\npython manage.py check\npython manage.py makemigrations --check --dry-run\npython -W error::django.utils.deprecation.RemovedInDjango70Warning \\\n -W error::django.utils.deprecation.RemovedInDjango2028Warning manage.py test\n```\n- `check` reports removed fields as system-check errors (for example `fields.E903` for `NullBooleanField`).\n- If `makemigrations --check` wants a migration, create it with `makemigrations` and include it in the change.\n\n## 5. Report\nSay which removed APIs you replaced, what django-upgrade rewrote, any migration you added, and that the scanner,\n`check`, `makemigrations --check` and the tests were clean.\n" }, { "path": "skills/django-6-guard/scripts/django6_guard.py", "role": "reference", "description": "Read-only scanner for removed Django APIs and Django 6 behaviour changes.", "skill": "django-6-guard", "agent": null, "install_to": { "claude-code": ".claude/skills/django-6-guard/scripts/django6_guard.py", "codex": ".agents/skills/django-6-guard/scripts/django6_guard.py", "cursor": ".agents/skills/django-6-guard/scripts/django6_guard.py", "gemini-cli": ".agents/skills/django-6-guard/scripts/django6_guard.py", "antigravity-cli": ".agents/skills/django-6-guard/scripts/django6_guard.py", "copilot": ".agents/skills/django-6-guard/scripts/django6_guard.py" }, "raw_url": "https://setupbay.com/raw/django-6-upgrade-guard/1.0.0/skills/django-6-guard/scripts/django6_guard.py", "raw_latest_url": "https://setupbay.com/raw/django-6-upgrade-guard/latest/skills/django-6-guard/scripts/django6_guard.py", "bytes": 7783, "lang": "markdown", "content": "#!/usr/bin/env python3\n\"\"\"Find Django code removed by 6.0 and 6.1 (and older removals agents still write) in a Django 6 project.\n\nUsage: python3 django6_guard.py [PATH ...] (default: the current folder)\n python3 django6_guard.py --list (print every rule)\n\nA \"guard: ok\" comment on a line silences its warnings (never its errors).\nPrints one line per finding: path:line: level [rule] what is wrong -> what to use\nExit 0 when nothing at \"error\" level is found, 1 when something is, 2 on bad usage.\nStandard library only.
