??? GII is a visual code generation module of YII, which is much easier and quicker than using the command line.

??? The latest YII comes with the GII module, so you do not have to install it. It is not enabled by default. You only need to configure it.

??? Still the pretected/config/main. php file

??? 'Modules' => array (
??????? // Uncomment the following to enable the Gii tool
??
?? ???? 'Giii '=> array (
?????? ? 'Class' => 'System. gii. GiiModule ',
?????? ? 'Password' => '000000 ′,
?????? ? // If removed, Gii defaults to localhost only. Edit carefully to taste.
?????? ? 'Ipfilters '=> array ('127. 0.0.1', ': 1 ′),
???? ),

??? ? You can remove the comment to use gii. The password is the password, and the ipFilters is the IP address restriction. if you remove the comment, the local machine is restricted. At the time of release, you can change this IP address to the IP address of the local machine to ensure security. However, in China, most of them are dynamic IP addresses. It is better to disable GII directly if you change the IP address frequently.

???? Create a table in the database for testing. You can directly import protected/data/schema. mysql. SQL, including a tb_user table and test data.

????? Openhttp://localhost/index.php?r=gii??? Enter the password to generate the code.
