任務是為兩個相關欄位制作驗證器。如果MCC不為空，那么您需要檢查OUTSIDE是否在型別欄位中傳遞。反之亦然。如果MCC為空，INSIDE則應在型別欄位中傳遞。
我寫了這段代碼，但它不起作用。有人可以告訴我最好的方法嗎

我嘗試了各種選擇。我已閱讀檔案，但找不到問題的答案。我使用 pydantic 進行自動化 api 測驗
uj5u.com熱心網友回復：
我想你正在尋找這個，驗證器MCC將不得不處理你的兩個案例。
@validator("MCC")
def check_passwords_match(cls, v, values):
if "type" not in values:
raise ValueError("TYPE VALIDATION FAILED")
if (v is not None and values["type"] != "OUTSIDE") or (
v is None and values["type"] != "INSIDE"
):
raise ValueError("MCC NOT EQUAL TYPE OPERATION")
return v
