Hi there, Its not a fringe use, but its a 3rd party dependency. So I don't see how it can be done in the scope of the library. But you're welcome to see if you do find a way to do.this neatly. To extend the providers map you simply need to subclass ModelFactory, override the method and extend the base value. This should resolve you issue I hope. |
[Roguelynn tutorial](https://www.roguelynn.com/words/asyncio-we-did-it-wrong/) feat(feedparser#issues): Add issue when using `updated_parser` [Deprecation warning when using `updated_parsed`](kurtmckee/feedparser#151) fix(pytest): update the tmpdir_factory type hints You should now use `TempPathFactory` instead of `TempdirFactory` fix(pytest#global-usage): Use `pytest-freezegun` globally [Most of the tests](https://medium.com/@boxed/flaky-tests-part-3-freeze-the-world-e4929a0da00e) work with frozen time, so it's better to freeze it by default and unfreeze it on the ones that actually need time to move. To do that set in your `tests/conftest.py` a globally used fixture: ```python if TYPE_CHECKING: from freezegun.api import FrozenDateTimeFactory @pytest.fixture(autouse=True) def frozen_time() -> Generator['FrozenDateTimeFactory', None, None]: """Freeze all tests time""" with freezegun.freeze_time() as freeze: yield freeze ``` feat(pytest): Ignore a warning of a specific package In the `pyproject.toml` ```toml filterwarnings = [ "error", # Until ktosiek/pytest-freezegun#35 is merged "ignore::DeprecationWarning:pytest_freezegun.*" ] ``` feat(python_snippets#How to raise a warning): How to raise a warning Warning messages are typically issued in situations where it is useful to alert the user of some condition in a program, where that condition (normally) doesn’t warrant raising an exception and terminating the program. For example, one might want to issue a warning when a program uses an obsolete module. ```python import warnings def f(): warnings.warn('Message', DeprecationWarning) ``` To test the function with pytest you can use [`pytest.warns`](https://docs.pytest.org/en/stable/how-to/capture-warnings.html#warns): ```python import warnings import pytest def test_warning(): with pytest.warns(UserWarning, match='my warning'): warnings.warn("my warning", UserWarning) ``` feat(python_snippets#Parse XML file with beautifulsoup): Parse XML file with beautifulsoup You need both `beautifulsoup4` and `lxml`: ```python bs = BeautifulSoup(requests.get(url), "lxml") ``` feat(python_snippets#Get a traceback from an exception): Get a traceback from an exception ```python import traceback traceback_str = ''.join(traceback.format_tb(e.__traceback__)) ``` feat(flakeheaven): Deprecate flakehell in favour of flakeheaven It's a fork maintained by the community, instead of an absent code dictator. feat(fastapi#Resolve the 307 error): Resolve the 307 error Probably you've introduced an ending `/` to the endpoint, so instead of asking for `/my/endpoint` you tried to do `/my/endpoint/`. feat(pdm): Version overriding now supports constrains Before you had to pin specific versions, which is not maintainable, now you can use constrains ```toml [tool.pdm.overrides] asgiref = ">=3.2.10" ``` feat(pdm#Show outdated packages): Show outdated packages ```bash pdm update --dry-run --unconstrained ``` fix(pydantic_factories): correct the type hints of the factory Use `Any` ```python class PersonFactory(ModelFactory[Any]): ... ``` feat(pydantic_factories#issues): Track issue when using with `pytest-freezegun` [Use pydantic-factories with pytest-freezegun](litestar-org/polyfactory#29) feat(python#install): Install a specific version * Install dependencies ```bash sudo apt install wget software-properties-common build-essential libnss3-dev zlib1g-dev libgdbm-dev libncurses5-dev libssl-dev libffi-dev libreadline-dev libsqlite3-dev libbz2-dev ``` * Select the version in https://www.python.org/ftp/python/ and download it ```bash wget https://www.python.org/ftp/python/3.9.2/Python-3.9.2.tgz cd Python-3.9.2/ ./configure --enable-optimizations sudo make altinstall ``` perf(regicide): fix typos fix(wallabag): Remove Wallabag rss issue as it's solved Rss feeds linked to the wallabag instance instead to the referenced article, not anymore.

Can I close this issue? Or do you intend to add a PR? |

Hi @Goldziher , sorry for the delay, what do you think if we add an optional argument to That way it would be easier for the users to extend the existent mapping without the need of subclassing and overriding the method. Furthermore, if you do that, it's difficult to stay updated with the changes in the default mapping |
|
hi @lyz-code - how is this relevant to this issue? |
|
Because then It would be easier for me to extend the from freezegun.api import FakeDatetime
class CustomModelFactory(ModelFactory):
additional_mappers = { FakeDateTime: cls._get_faker().date_time_between }And I wouldn't need to subclass |
|
Ok. Please create an issue with some examples of what you want to add, lets discuss it in a non-closed ticket. |
Hi @Goldziher, I'm having issues using
pydantic_factorieswithpytest_freezegun, the problem is that pytest_factories is not able to find the factory function for thedatetimeattributesAdding a
pdbtrace on line 339 I get the next result:If you feel it's a corner case and you don't want to support
pytest-freezegun, can you point me in the direction on how to extend the providers map locally?Thanks! :)
