無法同步數據庫

我無法遷移我的代碼。我在MySql中創建了一個數據庫和一個表，但是由於某種原因，我不得不卸載MySql，當我再次安裝它時，我將用戶名更改爲root。現在，它口口聲聲說無法同步數據庫

（1045，「訪問被拒絕的用戶 'djanu' @ 'localhost' 的（使用密碼：NO）」）

當我嘗試遷移

。當我第一次安裝它時，我將用戶命名爲djanu，並且我嘗試向用戶root授予權限，但同樣的消息不斷彈出。

這是我在settings.py

DATABASES = { 
    'default': { 
     'ENGINE': 'django.db.backends.mysql', 
     'NAME': 'applics', 
    'USER': 'root', 
    'Password': '531010', 
    'HOST': '', 
    'PORT': '',  
    } 
}

代碼和我的代碼，當我使用Python manage.py遷移，甚至的runserver

(myproject) C:\Users\home\myproject\collapp>python manage.py migrate

您在用戶設置中使用'USER'：'root'，''而不是'USER'：'djanu'' –

請嘗試使用root用戶相同的方式 – Harsha

您的數據庫配置中也有不同的大小寫。確保它匹配文檔！ –

這與我發生過多次。可能的解決方案是刪除遷移文件夾中的所有遷移，然後運行manage.py migrate。
