django.db.migrations.exceptions.NodeNotFoundError: Migration apitest.0001_initial dependencies reference nonexistent parent node ('product', '0001_initial')

問題原因：由於'product' 應用下的'0001_initial'文件不存在，而在 apitest應用下的0001_initial 文件中引用了product中的遷移記錄

問題解決：刪除 apitest->migrations下的0001_initial .py文件，再重新執行命令
