What's Changed

  • Multiple Annotated arguments support: 
    from typing import Annotated
from annotated_types import Ge
from pydantic.functional_validators import AfterValidator

@inject()
def f(a: Annotated[int, Ge(10), AfterValidator(lambda x: x + 10)]) -> int:
    return a

assert f(10) == 20
  • Support correct Generator annotation 
    @inject
 def simple_func(a: str) -> Iterator[int]:
     for _ in range(2):
         yield a

 for i in simple_func("1"):
     assert i == 1
  • solve async dependencies without subdependencies in parallel tasks
  • solve CustomField with async use_field in parallel

FastDepends - 2.2.6

Published by Lancetnik 10 months ago

What's Changed

Provides you with the ability to setup pydantic config using @inject

@inject(pydantic_config={"str_max_length": 8})
def limited_str(a: str):
    ...
 
limited_str("*" * 9)  # raises ValidationError

Also, added context manager method to override dependencies:

from fast_depends import Depends, dependency_provider, inject

def base_dep():
    return 1

def override_dep():
    return 2

@inject
def func(d=Depends(base_dep)):
    return d

with dependency_provider.scope(base_dep, override_dep):
    assert func() == 2

assert func() == 1

New CustomField syntax to support classes injection:

class Header(CustomField):
    def use(
        self,
        /,  # <- new thing
        **kwargs
    ):
        kwargs = super().use(**kwargs)
        kwargs[self.param_name] = kwargs["headers"][self.param_name]
        return kwargs

FastDepends - 2.2.4

Published by Lancetnik 10 months ago

What's Changed

Now you can use FastDepends to inject dependencies to your class constructors and/or methods!

from fast_depends import Depends, inject

def get_var():
    return 1

class Class:
    @inject
    def __init__(self, a = Depends(get_var)) -> None:
        self.a = a

    @inject
    def calc(self, a = Depends(get_var)) -> int:
        return a + self.a

assert Class().calc() == 2

FastDepends - 2.2.0 (2023-09-22) Generators support

Published by Lancetnik about 1 year ago

With this release, async and sync generator function support was added!

This case supports incoming and return types casting both

from fast_depends import inject

@inject
def func(a: str) -> int:
    for _ in range(3)
        yield a

for i in func(1):
    assert i ==  "1"

Also, @inject has an option to disable pydantic validation with cast=False. This way Depends and your custom fields are still working, but pydantic is not even called.

from fast_depends import inject

@inject(cast=False)
def func(a: str) -> int:
    return a

assert func(1.0) == 1.0
FastDepends - 2.1.0 (2023-07-17) Args and Kwargs supporting

Published by Lancetnik over 1 year ago

Now the package is able to validate not only a final decraled fields, but also an *args, **kwargs too!

@inject
def simple_func(
    a: int,
    *args: Tuple[float, ...],
    b: int,
    **kwargs: Dict[str, int],
):
    ...

This way, the all function variaty is supported

FastDepends - 2.0.1 (2023-06-21) PydanticV2 stable

Published by Lancetnik over 1 year ago

Stable and fulltested PydanticV2 and PydanticV1 both supporting!

FastDepends - 2.0.0b (2023-06-19) PydanticV2

Published by Lancetnik over 1 year ago

It is a totally new package with the same testcases and public interfaces!
It works with pydanticV1 and pydanticV2.0b3 both, so you can easy migrate to beta pydanticV2 Rust version and increase performance by 2-50x!

FastDepends - 1.1.0 (2023-04-18)

Published by Lancetnik over 1 year ago

Custom Field is here!

Now you are able to create your own Header, Path, BackgroundTasks or anything you wish fields with a custom behavior.
Take a look at the docs for details.
