嘗試使用Django設置mysql時出錯

Question

我是django的新手，正在嘗試將其與mysql連接。 我之前從未使用過設置環境變量的方法，當我運行django-admin dbshel​​l時，對於這個錯誤我有點困惑

(venv) dhcp-ccc-12919:project user$ django-admin dbshell
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/3.5/bin/django-admin", line 11, in <module>

django.core.exceptions.ImproperlyConfigured: Requested setting USE_I18N, but settings are not configured. You must either define the environment v
ariable DJANGO_SETTINGS_MODULE or call settings.configure() before accessing settings.

我的數據庫設置是

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'todo',
        'USER': 'root',
        'PASSWORD': 'password'
    }
}

Answer 1

以下可以幫助我使用Mysql設置Django。

步驟1：如果尚未安裝pymysql，請安裝。 對於Windows，請使用以下命令：

easy_install.exe pymysql

步驟2：在頂部的settings.py中編寫以下命令

import  pymysql

pymyql.install_as_MySQLdb()

然后在settings.py中按如下所示更改數據庫設置，

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': '<database_name>',
        'USER': '<mysql_username>',
        'PASSWORD' : '<password>',
        'HOST' : 'localhost',
        'PORT' : '3306',
    }
}

您可以通過以下方式測試來自django shell的mysql連接，

python manage.py shell
>>>from django.db import connection
>>> cursor = connection.cursor()

如果上面沒有輸出，則表明mysql安裝正確。

希望它對您有用。 讓我知道您是否需要其他幫助。

Answer 2

您應該使用manage.py而不是django-admin ，因為這會為您設置DJANGO_SETTINGS_MODULE變量。
