## Use the instance as a dependency { #use-the-instance-as-a-dependency }

Then, we could use this `checker` in a `Depends(checker)`, instead of `Depends(FixedContentQueryChecker)`, because the dependency is the instance, `checker`, not the class itself.

And when solving the dependency, **FastAPI** will call this `checker` like:

```Python

            c[0] = '.';
            c[1] = '.';
            c[14] = '.';
            n = new String(c);
        }

        sb.append(n).append("<").append(Hexdump.toHexString(this.hexCode, 2)).append(">");
        if (this.scope != null) {
            sb.append(".").append(this.scope);
        }
        return sb.toString();
    }

		// string "Totals"
		o = append(o, 0x82, 0xa6, 0x54, 0x6f, 0x74, 0x61, 0x6c, 0x73)
		o = msgp.AppendArrayHeader(o, uint32(60))
		for za0002 := range z[za0001].Totals {
			// map header, size 3
			// string "Total"
			o = append(o, 0x83, 0xa5, 0x54, 0x6f, 0x74, 0x61, 0x6c)
			o = msgp.AppendInt64(o, z[za0001].Totals[za0002].Total)
			// string "Size"
			o = append(o, 0xa4, 0x53, 0x69, 0x7a, 0x65)

## 현재 유저 주입하기

이제 *경로 작동*에서 `get_current_user`와 동일한 `Depends`를 사용할 수 있습니다.

{* ../../docs_src/security/tutorial002.py hl[31] *}

Pydantic 모델인 `User`로 `current_user`의 타입을 선언하는 것을 알아야 합니다.

이것은 모든 완료 및 타입 검사를 통해 함수 내부에서 우리를 도울 것입니다.

/// tip | 팁

요청 본문도 Pydantic 모델로 선언된다는 것을 기억할 것입니다.

여기서 **FastAPI**는 `Depends`를 사용하고 있기 때문에 혼동되지 않습니다.
