在使用

教程时,遇到如题目描述的问题,本来准备在文章下面评论做笔记的,发现“连接被重置”,开代理去评论,发现代理IP在blacklist上,于是只好写在这里


And now I want to record some problem I met when I learn, and also I will offer my solusion.
When I created the database My_manage_01, and then went to the http://localhost/yiitestapp/index.php/gii to click the Model Generator, it turn to be wrong, and it says like this:

CDbConnection failed to open the DB connection: SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO)

After suffering for one night, I finally find the answer. It's in the C:\xampp\htdocs\yiitestapp\protected\config\main.php, line 55. You need to add the database you created manually and so as the code.

Then everthing is OK.
