* 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
* Output a more clear configuration error
* Performance related improvements in config read handling
* Check python 3.6 with travis
* Revert the .travis.yml py36 inclusion
* Added tests for input error handling
* Thanks isort, isorted it out
* Make exit() function a bit more aesthetic
* Single quote -> double quote docstrings
* Whitespace removed
* Instead of using Literal types, overload QuerySet.values_list in the plugin. Fixes#43.
- Add a couple of extra type checks that Django makes:
1) 'flat' and 'named' can't be used together.
2) 'flat' is not valid when values_list is called with more than one field.
* Determine better row types for values_list/values based on fields specified.
- In the case of values_list, we use a Row type with either a single primitive, Tuple, or NamedTuple.
- In the case of values, we use a TypedDict.
- In both cases, Any is used as a fallback for individual fields if those fields cannot be resolved.
A couple other fixes I made along the way:
- Don't create reverse relation for ForeignKeys with related_name='+'
- Don't skip creating other related managers in AddRelatedManagers if a dynamic value is encountered
for related_name parameter, or if the type cannot be determined.
* Fix for TypedDict so that they are considered anonymous.
* Clean up some comments.
* Implement making TypedDict anonymous in a way that doesn't crash sometimes.
* Fix flake8 errors.
* Remove even uglier hack about making TypedDict anonymous.
* Address review comments. Write a few better comments inside tests.
* Fix crash when running with mypyc ("interpreted classes cannot inherit from compiled") due to the way I extended TypedDictType.
- Implemented the hack in another way that works on mypyc.
- Added a couple extra tests of accessing 'id' / 'pk' via values_list.
* Fix flake8 errors.
* Support annotation expressions (use type Any) for TypedDicts row types returned by values_list.
- Bonus points: handle values_list gracefully (use type Any) where Tuples are returned
where some of the fields arguments are not string literals.
- Add a couple of extra type checks that Django makes:
1) 'flat' and 'named' can't be used together.
2) 'flat' is not valid when values_list is called with more than one field.
* Support returning the correct values for the different QuerySet methods when using .values() and .values_list().
* Fix slicing on QuerySet. Fix django queries test, and remove some ignored errors that are no longer needed.
* Remove accidental change in RawQuerySet.
* Readded some still-necessary ignores to aggregation django test.
* Add more tests of first/last/earliest/last/__getitem__, per mkurnikov's comments.
- Fix .iterator()
* Re-add Iterator as base-class of QuerySet.
* Make QuerySet a Collection.
* - Fix return type for QuerySet.select_for_update().
- Use correct return type for QuerySet.dates() / QuerySet.datetimes().
- Use correct type params in return type for QuerySet.__and__ / QuerySet.__or__
- Re-add Sized as base class for QuerySet.
- Add test of .all() for all _Row types.
- Add test of .get() for all _Row types.
- Remove some redundant QuerySet method tests.
* Automatically fill in second type parameter for QuerySet.
... if second parameter is omitted.
* Fix bug where models with a class variable using a manager defined would interfere with other managers.
- Fill in the type argument for that particular instance of the manager, rather than modifying the bases of the Manager type.
- Instantiate a new Instance from determine_proper_manager_type so The code doesn't crash under mypy-mypyc.
* Use helpers.reparametrize_instance per review comment.
* Updated ignored errors in Django test for get_objects_or_404.
- For some reason, `Manager[nothing]` is now removed from expected types.
However, I think this makes sense anyway, as Manager is a subclass of QuerySet.
