How to inject dependency in class #326
Description
i have class to be injected by repositry class with DI, it looks like this:
// handler.py
class Handler: @inject def __init__(self, rating_repo: Provide[Container.repo.rating] = None): self.rating_repo = rating_repo def save_rating(self, cmd: SaveRating): runner_rating = RunnerRating() runner_rating.add_runner(cmd.runner) runner_rating.add_merchant(cmd.childMerchant) runner_rating.add_rating(cmd.rating) self.rating_repo.add(runner_rating) then i try to test the class with unittest:
import unittest from src.container import Container from src.runner_rating.service.handler import Handler from src.runner_rating.domain.commands import SaveRating from src.runner_rating.domain.models import Rating, Runner, ChildMerchant class HandlerTest(unittest.TestCase): def setUp(self): self.container = Container() self.container.config.from_ini('env.dev.ini') self.container.wire(modules=[Handler]) rating = Rating(**{ "value": 5, "tags": [ "ketepatan waktu pengiriman", "kondisi barang", "keramahan pengirim" ] }) runner = Runner(**{ "id": "25b1c252-104c-4ebe-804d-ab6e63007ca1", "employeeNumber": "916452", "name": 'namarunner' }) merchant = ChildMerchant(**{ "id": "96cc8d00-f48f-4731-a477-52dbe82a3e15", "code": "3412409", "mor": "3", "name": "SPBU 3412409", }) self.data = SaveRating(id='tes', runner=runner, rating=rating, childMerchant=merchant) def test_save_rating(self): handler = Handler() handler.save_rating(self.data) but the repo_rating is None/ empty? how to do DI in class?
if i remove None default param, the test show error thant Handler class need 1 argument in initializaiton
thank you
