Isso pode depender principalmente da ferramenta que você usa para **instalar** esses requisitos.

O caminho mais comum de fazer isso é ter um arquivo `requirements.txt` com os nomes dos pacotes e suas versões, um por linha.

Você, naturalmente, usaria as mesmas ideias que você leu em [Sobre Versões do FastAPI](versions.md){.internal-link target=_blank} para definir os intervalos de versões.

## CRUD utils

Now let's see the file `sql_app/crud.py`.

In this file we will have reusable functions to interact with the data in the database.

**CRUD** comes from: **C**reate, **R**ead, **U**pdate, and **D**elete.

...although in this example we are only creating and reading.

### Read data

        Optional[Sequence[str]],
        Doc(
            """
            OAuth2 scopes required for the *path operation* that uses this Security
            dependency.

            The term "scope" comes from the OAuth2 specification, it seems to be
            intentionaly vague and interpretable. It normally refers to permissions,
            in cases to roles.
