Вопрос подписчика

Задает @FieryDruid:

«Генерировал ли кто-нибудь индексы для моделей sqlalchemy в рантайме?

Так сложилось, что индексов надо достаточно много и генерируются они по определенному принципу, из-за чего вручную их описывать в модели очень не удобно.

Написали генератор, который за нас заполняет __tableargs__ модели

Но из-за такого генератора появилось странное поведение alembic

Теперь, при каждой новой миграции, он в upgrade сначала удаляет все старые индексы, а потом добавляет их же (первая генерация нормальная, но каждая последующая сопровождается такими вот артефактами)

Может кто сталкивался или есть мысли из-за чего такое поведение может быть? Порядок генерируется один и тот же, нейминги, типы и т.д тоже».

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

Telegram is a messaging app with a focus on speed and security, it’s super-fast, simple and free. You can use Telegram on all your devices at the same time — your messages sync seamlessly across any number of your phones, tablets or computers.

As a result, you can access your messages from several devices at once, including tablets and computers, and share an unlimited number of photos, videos and files (doc, zip, mp3, etc.) of up to 2 GB each. And if you don't want to store all that data on your device, you can always keep it in the cloud.Thanks to our multi-data center infrastructure and encryption, Telegram is faster and way more secure.
