* Type the return value of lazy translation functions as Promise.
The return value of the lazy translation functions is a proxied
`Promise` object.

* Add proxied functions for Promise.
Although there is nothing defined in `Promise` itself, the only
instances of `Promise` are created by the `lazy` function, with magic
methods defined on it.

* Add _StrPromise as a special type for Promise objects for str.
This allows the user to access methods defined on lazy strings while
still letting mypy be aware of that they are not instances of `str`.
The definitions for some of the magic methods are pulled from typeshed. We need
those definitions in the stubs so that `_StrPromise` objects will work properly
with operators, as refining operator types is tricky with the mypy
plugins API.
The rest of the methods will be covered by an attribute hook.

* Implement _StrPromise attribute hook.
This implements an attribute hook that provides type information for
methods that are available on `builtins.str` for `_StrPromise` except
the supported operators. This allows us to avoid copying stubs from the
builtins for all supported methods on `str`.

* Allow message being a _StrPromise object for RegexValidator.
One intended usage of lazystr is to postpone the translation of the
error message of a validation error. It is possible that we pass a
Promise (specifically _StrPromise) and only evaluate it when a
ValidationError is raised.

* Fix stubs related to `(Async)RequestFactory` and `(Async)Client`
* Revert incorrect removal.
* Allow set as `unique_together`, use shared type alias.
* Revert `Q.__init__` to use only `*args, **kwargs` to remove false-positive with `Q(**{...})`
* Add abstract methods to `HttpResponseBase` to create common interface.
* Remove monkey-patched attributes from `HttpResponseBase` subclasses.
* Add QueryDict mutability checks (+ plugin support)
* Fix lint
* Return back GenericForeignKey to `Options.get_fields`
* Minor fixup
* Make plugin code typecheck with `--warn-unreachable`, minor performance increase.
* Better types for `{unique, index}_together` and Options.
* Fix odd type of `URLResolver.urlconf_name` which isn't a str actually.
* Better types for field migration operations.
* Revert form.files to `MultiValueDict[str, UploadedFile]`
* Compatibility fix (#916)
* Do not assume that `Annotated` is always related to django-stubs (fixes#893)
* Restrict `FormView.get_form` return type to `_FormT` (class type argument). Now it is resolved to `form_class` argument if present, but also errors if it is not subclass of _FormT
* Fix CI (make test runnable on 3.8)
* Fix CI (make test runnable on 3.8 _again_)
* 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.
