你可以在 `pyproject.toml` 檔案中指定你的 app 位置，例如：

```toml
[tool.fastapi]
entrypoint = "main:app"
```

這個 `entrypoint` 會告訴 `fastapi` 指令應該像這樣匯入 app：

```python
from main import app
```

如果你的程式碼結構是這樣：

```
.
├── backend
│   ├── main.py
│   ├── __init__.py
```

那麼你應該把 `entrypoint` 設為：

```toml
[tool.fastapi]
entrypoint = "backend.main:app"
```

這等同於：

```python

	}, {
		SQL:    "?",
		Vars:   []interface{}{clause.Column{Table: "table", Name: "col"}},
		Result: "`table`.`col`",
	}, {
		SQL:    "?",
		Vars:   []interface{}{clause.Column{Table: "table", Name: "col", Raw: true}},
		Result: "table.col",
	}, {
		SQL:    "?",
		Vars:   []interface{}{clause.Column{Table: "table", Name: clause.PrimaryKey, Raw: true}},
		Result: "table.id",
