WindowsXP + RadRails + MySQL scaffold error fix tip.

In case of  using the RadRails IDE on WindowsXP with mysql. If you got an error message like this 'uninnitialize constant Mysql' when command with 'ruby script/generate scaffold Xxxx'.

I don't know exactly why occured this type of error. 

To fix it, you must do the following:

1. Goto your mysql home\bin directory : C:\mysql\bin 

2. There is only one DLL file. File name is libmySQL.dll. 

3. Copy libmySQL.dll file to C:\Windows directory. 

All done. Happy Rails ~~
