新的Django/python用戶有__init__問題我已經定義了幾個類，並且想用另一個類作爲另一個字段

Question

我是一個新的Django用戶，並且被一些繼承和實例化的特性所困惑，特別是創建一個用戶定義的類型類的字段。

當我嘗試從管理頁面添加藝術家，我得到 蟒蛇類型錯誤：初始化（）失蹤5個所需的位置參數：「姓名」，「FIRST_NAME」，「姓氏」，「網站」和「 Instagram的」 [18 /月/ 2017年21點43分28秒] 「GET /管理/ showyourwork /藝術家/添加/ HTTP/1.1」 500 110559

您不應該從django.model.Model覆蓋__init__方法。 如果您需要類似的東西，文檔可以指導您如何處理此問題： https://docs.djangoproject.com/en/1.11/ref/models/instances/#django.db.models.Model
