Question

I get the below error when running a custom command from the yiic shell.
I am using the latest MAMP 2.0.2 on OS X 10.7.2

I am not sure what the error means by reader or member does not exist?

Line 56 is: $role->addChild("reader"); and the full code of the custom command and and terminal output is below:

users-MacBook-Air:protected user$ ./yiic shell ../index.php
Yii Interactive Tool v1.1 (based on Yii v1.1.2)
Please type 'help' for help. Type 'exit' to quit.

I think you need to create the “reader” operation (or task, or role) before you can add it to the “member” role with addChild(). Something like this:

<?php
// define reader role
$role=$this->_authManager->createRole("reader");
// add some operations
$role->addChild("readIssue");
// NOW create the member role
$role=$this->_authManager->createRole("member");
// and now that reader is defined, we can add it to member
$role->addChild("reader");
?>

I’m sure you have already found this, but there are more details on the Yii Guide page for Role-based ACL.
