summer-boot
After spring it comes the summer.
Installation
pip install python-summer-bootInversion of control
summer-boot provides an easy dependency injection by splitting classes between services and injectors. A service is a dependency and an injector is a class that consumes dependencies.
You can discover services with the disvover_services function.
It is recommended to create a setup file located in your sources root and call discover services function there, once.
Here you have an example:
import os
from summer.inversion_of_control.service_locator import get_executable_parent_path, discover_services
executable_parent_path = get_executable_parent_path(os.getcwd())
def setup():
discover_services(executable_parent_path)You can define services using the @service decorator at class level.
from summer.inversion_of_control.dependencies import service
from src.mock_entity.core.i_repository import IRepository
@service()
class PostgreRepository(IRepository):
def custom_method(self):
return "Postgre repository"Here the code of IRepository:
from abc import ABC, abstractmethod
class IRepository(ABC):
@abstractmethod
def custom_method(self) -> str:
raise NotImplementedErrorFinally, you can consume injected dependencies with the @autowired decorator, upside the function that needs
dependencies. In most of the cases it will be the __init__ function:
from summer.inversion_of_control.dependencies import autowired
from src.mock_entity.core.i_repository import IRepository
class UseCase:
@autowired
def __init__(self, repository: IRepository):
self.repository = repository
def my_use_case(self) -> str:
return self.repository.custom_method()Models
SummerBoot implements some models using inheritance from pydantic.
CamelModel
A model which every attribute is represented as camelCase perhaps is coded as snake_case. I.e.:
from summer.models.camel.camel_model import CamelModel
class MockCamelModel(CamelModel):
mock_attribute: str = "mock"
