問題背景：
使用pycharm創建完成django項目（項目名稱為：mydjangopro，app名稱為my_blog）
,
本想登錄后台直接輸入地址：http://127.0.0.1:8000/admin后，登錄頁面出現了，隨便（username:admin,password:admin）輸入了賬戶名和密碼卻進入了錯誤黃頁：
從錯誤代碼中我們也發現說是數據沒有找到表相關問題，從程序工程上此時查看多了一個sqllite的數據庫，這說明默認django使用的數據庫是sqllite。
解決上邊問題的方案：
1）在pycharm的tools->"Run manage.py task...'：
直接點擊，會在pycharm右側代碼欄下邊彈出一個“manage.py@mydjangopro”命令運行窗口。
2）在“manage.py@mydjangopro”命令運行窗口中輸入:makemigrations
manage.py@mydjangoapro > makemigrations "E:\Program Files\JetBrains\PyCharm 2017.2.3\bin\runnerw.exe" C:\Python27\python.exe "E:\Program Files\JetBrains\PyCharm 2017.2.3\helpers\pycharm\django_manage.py" makemigrations E:/Work/django/mydjangoapro No changes detected
3）在“manage.py@mydjangopro”命令運行窗口中輸入:migrate
manage.py@mydjangoapro > migrate "E:\Program Files\JetBrains\PyCharm 2017.2.3\bin\runnerw.exe" C:\Python27\python.exe "E:\Program Files\JetBrains\PyCharm 2017.2.3\helpers\pycharm\django_manage.py" migrate E:/Work/django/mydjangoapro Operations to perform: Apply all migrations: admin, auth, contenttypes, sessions Running migrations: Applying contenttypes.0001_initial...

4）在“manage.py@mydjangopro”命令運行窗口中輸入:createsuperuser
manage.py@mydjangoapro > createsuperuser "E:\Program Files\JetBrains\PyCharm 2017.2.3\bin\runnerw.exe" C:\Python27\python.exe "E:\Program Files\JetBrains\PyCharm 2017.2.3\helpers\pycharm\django_manage.py" createsuperuser E:/Work/django/mydjangoapro Username (leave blank to use 'administrator'): admin Email address: admin@admin.com Warning: Password input may be echoed.

Following files were affected E:\Work\django\mydjangoapro\db.sqlite3 Process finished with exit code 0
5）重新進入登錄頁面：http://127.0.0.1:8000/admin，在username中輸入admin，密碼輸入：new.1234，點擊登錄之后成功跳轉到了后台管理頁面：
