问题背景：
使用pycharm创建完成django项目（项目名称为：mydjangopro，app名称为my_blog）
,
本想登录后台直接输入地址：http://127.0.0.1:8000/admin后，登录页面出现了，随便（username:admin,password:admin）输入了账户名和密码却进入了错误黄页：
从错误代码中我们也发现说是数据没有找到表相关问题，从程序工程上此时查看多了一个sqllite的数据库，这说明默认django使用的数据库是sqllite。
解决上边问题的方案：
1）在pycharm的tools->"Run manage.py task...'：
直接点击，会在pycharm右侧代码栏下边弹出一个“manage.py@mydjangopro”命令运行窗口。
2）在“manage.py@mydjangopro”命令运行窗口中输入:makemigrations
manage.py@mydjangoapro > makemigrations"E:\Program Files\JetBrains\PyCharm .2.3\bin\runnerw.exe" C:\Python27\python.exe "E:\Program Files\JetBrains\PyCharm .2.3\helpers\pycharm\django_manage.py" makemigrations E:/Work/django/mydjangoaproNo changes detected
3）在“manage.py@mydjangopro”命令运行窗口中输入:migrate
manage.py@mydjangoapro > migrate"E:\Program Files\JetBrains\PyCharm .2.3\bin\runnerw.exe" C:\Python27\python.exe "E:\Program Files\JetBrains\PyCharm .2.3\helpers\pycharm\django_manage.py" migrate E:/Work/django/mydjangoaproOperations to perform:Apply all migrations: admin, auth, contenttypes, sessionsRunning migrations:Applying contenttypes.0001_initial...

4）在“manage.py@mydjangopro”命令运行窗口中输入:createsuperuser
manage.py@mydjangoapro > createsuperuser"E:\Program Files\JetBrains\PyCharm .2.3\bin\runnerw.exe" C:\Python27\python.exe "E:\Program Files\JetBrains\PyCharm .2.3\helpers\pycharm\django_manage.py" createsuperuser E:/Work/django/mydjangoaproUsername (leave blank to use 'administrator'): adminEmail address: admin@Warning: Password input may be echoed.Password: adminWarning: Password input may be echoed.Password (again): adminThe password is too similar to the email address.This password is too short.

5）重新进入登录页面：http://127.0.0.1:8000/admin，在username中输入admin，密码输入：new.1234，点击登录之后成功跳转到了后台管理页面：
