* Reparametrize managers without explicit type parameters
This extracts the reparametrization logic from #1030 in addition to
removing the codepath that copied methods from querysets to managers.
That code path seems to not be needed with this change.
* Use typevars from parent instead of base
* Use typevars from parent manager instead of base manager
This removes warnings when subclassing from something other than the
base manager class, where the typevar has been restricted.
* Remove unused imports
* Fix failed test
* Only reparametrize if generics are omitted
* Fix docstring
* Add test with disallow_any_generics=True
* Add an FAQ section and document disallow_any_generics behaviour
* Implement support for `<QuerySet>.as_manager()`

* Add support for inline from_queryset in model classes
This adds support for calling <Manager>.from_queryset(<QuerySet>)()
inline in models, for example like this:
class MyModel(models.Model):
objects = MyManager.from_queryset(MyQuerySet)()
This is done by inspecting the class body in the transform_class_hook
* Fix missing methods on copied manager
* Add test and other minor tweaks
* Always create manager at module level
When the manager is added at the class level, which happened when it was
created inline in the model body, it's not possible to retrieve the
manager again based on fullname. That lead to problems with inheritance
and the default manager.
* Fix manager types scope
* Restore incremental mode and mention in developer docs
* Separate dev mypy config and regular one
* Document config files usage
Instead of copying methods over from a QuerySet passed to a basemanager
when invoking '<BaseManager>.from_queryset', any QuerySet methods are
declared as attributes on the manager.
This allows us to properly lookup any QuerySet method types via a
'get_attribute_hook' and will thus remove disorienting phantom errors
occuring from mypy trying to resolve types only existing in the module
where the _original_ (and real) queryset method was declared.
* Fix `MyModel.objects.filter(...).my_method()`
* Fix regression: `MyModel.objects.filter(...).my_method()` no longer worked when using from_queryset
This also fixes the self-type of the copied-over methods of the manager generated by from_queryset.
Previously it was not parameterized by the model class, but used Any.
The handling of unbound types is not tested here as I have not been able to
find a way to create a test case for it. It has been manually tested
against an internal codebase.
* Remove unneeded defer.
* 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.
* Adds support for pyproject.toml files
Since mypy 0.900 the pyproject.toml files are supported.
This PR adds a support for it. It searchs for a `tool.django-stubs` section. This is an example configuration:
```
[tool.django-stubs]
django_settings_module = "config.settings.local"
```
Fixes#638
* Added TOML tests
* Use textwrap.dedent instead of trying to manually replace spaces
* additional defer() to offset the effect of using the type before declaring
* linter fix
* linter fix
* linter fix
* test case
