* QuerySet.annotate returns self-type. Attribute access falls back to Any.
- QuerySets that have an annotated model do not report errors during .filter() when called with invalid fields.
- QuerySets that have an annotated model return ordinary dict rather than TypedDict for .values()
- QuerySets that have an annotated model return Any rather than typed Tuple for .values_list()
* Fix .annotate so it reuses existing annotated types. Fixes error in typechecking Django testsuite.
* Fix self-typecheck error
* Fix flake8
* Fix case of .values/.values_list before .annotate.
* Extra ignores for Django 2.2 tests (false positives due to tests assuming QuerySet.first() won't return None)
Fix mypy self-check.
* More tests + more precise typing in case annotate called before values_list.
Cleanup tests.
* Test and fix annotate in combination with values/values_list with no params.
* Remove line that does nothing :)
* Formatting fixes
* Address code review
* Fix quoting in tests after mypy changed things
* Use Final
* Use typing_extensions.Final
* Fixes after ValuesQuerySet -> _ValuesQuerySet refactor. Still not passing tests yet.
* Fix inheritance of _ValuesQuerySet and remove unneeded type ignores.
This allows the test
"annotate_values_or_values_list_before_or_after_annotate_broadens_type"
to pass.
* Make it possible to annotate user code with "annotated models", using PEP 583 Annotated type.
* Add docs
* Make QuerySet[_T] an external alias to _QuerySet[_T, _T].
This currently has the drawback that error messages display the internal type _QuerySet, with both type arguments.
See also discussion on #661 and #608.
Fixes#635: QuerySet methods on Managers (like .all()) now return QuerySets rather than Managers.
Address code review by @sobolevn.
* Support passing TypedDicts to WithAnnotations
* Add an example of an error to README regarding WithAnnotations + TypedDict.
* Fix runtime behavior of ValuesQuerySet alias (you can't extend Any, for example).
Fix some edge case with from_queryset after QuerySet changed to be an
alias to _QuerySet. Can't make a minimal test case as this only occurred
on a large internal codebase.
* Fix issue when using from_queryset in some cases when having an argument with a type annotation on the QuerySet.
The mypy docstring on anal_type says not to call defer() after it.
This addresses an obscure crash we're getting when defining a GenericForeignKey
subclass on a model.
Not sure how this slipped through type checking since
`helpers.lookup_class_typeinfo -> Optional[TypeInfo]` while
`.get_private_descriptor_type(type_info: TypeInfo)` so this should be a clear
type violation.
