    通过创建仅专用于与数据库交互（获取用户或项目）的函数，独立于*路径操作函数*，您可以更轻松地在多个部分中重用它们，并为它们添加单元测试。

### 创建数据

现在创建实用程序函数来创建数据。

它的步骤是：

* 使用您的数据创建一个 SQLAlchemy 模型*实例。*
* 使用`add`来将该实例对象添加到您的数据库。
* 使用`commit`来对数据库的事务提交（以便保存它们）。
* 使用`refresh`来刷新您的数据库实例（以便它包含来自数据库的任何新数据，例如生成的 ID）。

Como ele roda um comando após o outro, modificando e revertendo muitos arquivos, ele demora um pouco para concluir, então pode ser um pouco mais fácil utilizar `scripts/format.sh` frequentemente e `scripts/format-imports.sh` somente após "commitar uma branch".

## Documentação

Primeiro, tenha certeza de configurar seu ambiente como descrito acima, isso irá instalar todas as requisições.

### Don't worry about style

* Don't worry too much about things like commit message styles, I will squash and merge customizing the commit manually.

* Also don't worry about style rules, there are already automatized tools checking that.

And if there's any other style or consistency need, I'll ask directly for that, or I'll add commits on top with the needed changes.

### Check the code

* Nie przejmuj się zbytnio rzeczami takimi jak style wiadomości commitów, przy wcielaniu pull requesta łączę commity i modyfikuję opis sumarycznego commita ręcznie.

* Nie przejmuj się również stylem kodu, automatyczne narzędzia w repozytorium sprawdzają to samodzielnie.

A jeśli istnieje jakaś konkretna potrzeba dotycząca stylu lub spójności, sam poproszę o zmiany lub dodam commity z takimi zmianami.

### Sprawdź kod

## Documentation

Tout d'abord, assurez-vous que vous configurez votre environnement comme décrit ci-dessus, qui installera toutes les exigences.

* Machen Sie sich nicht zu viele Gedanken über Dinge wie den Stil von Commit-Nachrichten, ich werde den Commit manuell zusammenführen und anpassen.

* Machen Sie sich auch keine Sorgen über Stilregeln, es gibt bereits automatisierte Tools, die das überprüfen.

Und wenn es irgendeinen anderen Stil- oder Konsistenz-Bedarf gibt, bitte ich direkt darum oder füge zusätzliche Commits mit den erforderlichen Änderungen hinzu.

### Den Code überprüfen

### Create data

Now create utility functions to create data.

The steps are:

* Create a SQLAlchemy model *instance* with your data.
* `add` that instance object to your database session.
* `commit` the changes to the database (so that they are saved).
* `refresh` your instance (so that it contains any new data from the database, like the generated ID).
