Urlmanager Show Title Instead Of Id

Hello Yii!

I've been trying to make my url more clean. What I have is:

site/projects/projects/id/3.html

or

site/projects/projects/update/id/3.html when i am updating..

I need to show the title of my project, not the id. Like that, only showing the module and the title:

site/projects/title.html

This is my actual code:

'urlManager'=>array(
      'urlFormat'=>'path',
      'showScriptName'=>false,
      'urlSuffix'=>'.html',
      'rules'=>array(
            '<controller:\w+>/<id:\d+>'=>'<controller>/view',
            '<controller:\w+>/<action:\w+>/<id:\d+>'=>'<controller>/<action>',
            '<controller:\w+>/<action:\w+>'=>'<controller>/<action>',   			
			),
		),

I tried many things like changing 'd' for 'w' and also 'id' for 'name' as i read in others posts, but nothing works.

This are other things that i tried:

 'rules'=>array(
    	'<_c:(projects)>/<_a:(create|update|delete)>/<id:\d+>' => '<_c>/<_a>',
    	'<_c:(projects)>/view/' => '<_c>/<_a>',
    	'<_c:(projects)>/<id:\d+>' => '<_c>/read',
    	'<_c:(projects)>s' => '<_c>/list',
)
//also using modules rules, i have this site/projects/projects/id/3.html:

'rules'=>array(
      '<module:\w+>/<controller:\w+>/view/<id:\w+>'=>'<module>/<controller>/<title:\w+>', 
	'<module:\w+>/<controller:\w+>/<action:\w+>/<id:\w+>'=>'<module>/<controller>/<action>',
      '<module:\w+>/<controller:\w+>/<action:\w+>'=>'<module>/<controller>/<action>',

I am lose, what can i do?

Thanks everyone for your time...!!!
