Использование Pydantic сегодня стало нормой, и это правильно. Но иногда на ревью вижу, что используют его не всегда корректно. Например, метод BaseModel.model_dump() по умолчанию не преобразует стандартные типы, такие как datetime, UUID или Decimal, в простой сериализуемый для JSON вид. Тогда пишут кастмоный сериализатор для этих типов чтобы функция json.dump() не падала с ошибкой. import uuid from datetime import datetime from decimal import Decimal from uuid import UUID from pydantic import BaseModel class MyModel(BaseModel): id: UUID date: datetime value: Decimal obj = MyModel( id=uuid.uuid4(), date=datetime.now(), value='1.23' ) print(obj.model_dump()) # не подходит для json.dump # { # 'id': UUID('4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1'), # 'date': datetime.datetime(2025, 12, 12, 12, 12, 12, 111111), # 'value': Decimal('1.23') # } # добавляем свой кастомный сериализатор json.dumps(obj.model_dump(), cls=MySerializer) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2025-12-12T12:12:12.111111', # 'value': '1.23' # } В данном случае класс MySerializer обрабатывает datetime, UUID и Decimal. Например так: class MySerializer(json.JSONEncoder): def default(self, o): if isinstance(o, Decimal): return str(o) elif isinstance(o, datetime): return o.isoformat() elif isinstance(o, UUID): return str(o) return super().default(o) Специально для тех, кто всё еще так делает - в этом нет необходимости! Pydantic может это сделать сам, просто нужно добавить параметр mode="json". json.dumps(obj.model_dump(mode="json")) # { # 'id': '4f8c1bc4-25fd-40cd-9dbe-2c73639b0dc1', # 'date': '2012-12-12T12:12:12.111111', # 'value': '1.23' # } #pydantic#libs

🧑‍💻Review: Farmix – The Innovative Force in TON DeFi ☺️Farmix appeared relatively recently, it is a semi-finalist of #DoraHacks hackathon. In a nutshell, it is a marginal farming protocol that allows you to significantly increase the profitability of your farms by using leverage. 🪙 We have already tested their farming pools a couple of weeks ago, everything went well and without complications. At that time, the APR in the farms was very high, some pairs gave up to 9,000% APR. Below is a short guide for working with Farmix. 🐷 On average, #Farmix farms are 3-5 times higher than in #DEX pools. There are two options to earn income for providing your assets: Lending and Farms. We will look at the Farms option, because this is the most interesting: 🟡Log in to Farmix and connect your MTW wallet. 🟡 Go to the "Farmers" tab and find the pair you are interested in, for example we will use the STORM/TON pair. 🟡 First, select "Borrow asset" — this is the asset in which you will take a loan for leverage in the farm. In the case of the STORM/TON farm, only the TON loan asset is available. 🟡Enter in the $STORM/$TON fields how much STORM and TON you will provide as collateral. In #Farmix you can open a farm with one token, it is not necessary to provide both tokens, as the smart contract itself will convert the tokens into a 50/50 pair and form LP tokens. 🟡Select the leverage (Leverage slider) with which you want to open the farm. The higher the leverage, the higher the APR of the farm, but the liquidation risks also increase. 🟡Click Open position at the bottom, sign the transaction in the wallet and in a few minutes your first farm will be open. ⚠️Important: Please note that leverage is only provided for collateral in $TON , $USDT , $tsTON, $stTON, $NOT . Any position with leverage > 1 has its own health factor. HF > 1.3 is considered moderate, HF = 1 - the position is liquidated. 📊 At first glance, the guide may seem complicated, but everything is generally intuitive. If you have any questions about the work of the project, farms, etc., you can ask them 🔔in our chat. You will also receive RP points for staking and farming, more details in the "Reward activities" tab. And as usual #NFR#DYOR Farmix | Channel | Project documentation
