Django中預設使用sqlite3資料庫,今天研究了下如何將它換成常見的mysql資料庫。
由於專案用得python3,而MySQLdb沒有支援python3的版本,如果使用python3.x版本時,pip install MySQLdb時會報錯。
後來通過谷歌發現可以使用pymysql替代MySQLdb
1 在專案根目錄下的__init__.py檔案中加入如下程式碼:
import pymysql
pymysql.install_as_MySQLdb()
2 使用mysqlclient代替MySQLdb,安裝方式為:
pip install mysqlclient
3 更改專案setting.py中對資料庫的配置為:
DATABASES = {
`default`: {
`ENGINE`: `django.db.backends.mysql`,
`NAME`: `test`,
`USER`: `username`,
`PASSWORD`: `passwd`,
`HOST`: `localhost`,
`PORT`: `3306`
}
}
4 最後通過python manage.py migrate
命令,Django會在資料庫中自動建立相應的表

5 在建立admin使用者時,遇到了如下報錯
python manage.py createsuperuser
Superuser creation skipped due to not running in a TTY. You can run `manage.py createsuperuser` in your project to create one manually.
後來查了一下,是因為使用了git來執行命令,切換到Windows自帶的命令列,可以解決該問題!
