Question

I’m confused about the Yii’s AuthManager in general and the schema used for DB tables.

1. The type field in the AuthItem table can be only between 0 and 2 ( Role=2, Task=1, Operation=0 ) ?
2. Could you make me an example of what I can find stored in the bizrule and data fields using the blog used in the tutorial ?
3. The userid field must be a varchar ?

This schema ( for MySQL ) generates any conflict ?

CREATE TABLE `AuthItem` (
  `name` varchar(60) NOT NULL,
  `type` tinyint(1) unsigned NOT NULL,
  `description` varchar(255),
  `bizrule` text,
  `data` text,
  PRIMARY KEY (`name`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `AuthItemChild` (
  `parent` varchar(60) NOT NULL,
  `child` varchar(60) NOT NULL,
  PRIMARY KEY (`parent`,`child`),
  FOREIGN KEY (`parent`) REFERENCES `AuthItem` (`name`)
    ON DELETE CASCADE 
    ON UPDATE CASCADE,
  FOREIGN KEY (`child`) REFERENCES `AuthItem` (`name`)
    ON DELETE CASCADE
    ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

CREATE TABLE `AuthAssignment` (
  `itemname` varchar(60) NOT NULL,
  `userid` int(10) unsigned NOT NULL,
  `bizrule` text,
  `data` text,
  PRIMARY KEY (`itemname`,`userid`),
  FOREIGN KEY (`itemname`) REFERENCES `AuthItem` (`name`)
    ON DELETE CASCADE
    ON UPDATE CASCADE,
  FOREIGN KEY (`userid`) REFERENCES `User` (`userid`)
    ON DELETE CASCADE
    ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

THANKS IN ADVANCE!

Answer 1

1. Yes type field have to be one of those values.

   0: operation, 1: task, 2: role
   

2. bizrule can be any string that holds an executable PHP code which returns false or true and ends with a semicolon. And data should be a string contains some serialized value(s), you can use them by operating $data variable in your bizrule.

3. userid field can be of any type I think, but default varchar implementation comes from here.
