Doubt about charpter 8 rbac

Archives Agile Web Application Development with Yii1.1 and

Hello friends

I’m using Yii 1.1.4

I created the file RbacCommand.php:




<?php

class RbacCommand extends CConsoleCommand

{

    private $authManager;


    public function getHelp()

    {

        return <<<EOD

        USAGE

         rbac


        DESCRIPTION

         This command generates an initial RBAC authorization hierarchy.


        EOD;

    }


    /*

      Execute the action

      @param array command line paramenters specific for this command

    */

    public function run($args)

    {

        //ensure that an authManager is defined as this is mandatory for creating an auth heirarchy

        if(($this->_authManager=Yii::app()->authManager)===null)

        {

            echo "Error: an authorization manager, named, 'authManager' must be configured to use this command.\n";

            echo "If you already added 'authManager' component in application configuration, \n";

            echo "please quit an re-enter the yiic shell.\n";

            return;

        }


        //provide the oportunity for the use to abort the request

        echo "create, read, update and delete user,\n";

        echo "create, read, update and delete project,\n";

        echo "create, read, update and delete issue,\n";

        echo "Would you like to continue?[Yes][No] ";


        //check the input from the user and continue if they indicate yes ti the above question

        if(!strncasecmp(trim(fgets(STDIN)), 'y', 1))

        {

            //first we need to remove all operations, roles, child relationships andassignments

            $this->_authManager->clearAll();


            //create the lowest leveloperations for users

            $this->_authManager->createOperation("createUser","create a new user");

            $this->_authManager->createOperation("readUser", "read user profile information");

            $this->_authManager->createOperation("updateUser", "update a users information");

            $this->_authManager->createOperation("deleteUser", "remove a user from a project");


            //create the lowest level operations for projects


            $this->_authManager->createOperation("createProject", "create a new project");

            $this->_authManager->createOperation("readProject", "read project information");

            $this->_authManager->createOperation("updateProject", "update project information");

            $this->_authManager->createOperation("deleteProject", "delete a project");


            //create the lwest level operations for issues

            $this->_authManager->createOperation("createIssue", "create a new issues");

            $this->_authManager->createOperation("readIssue", "read issue information");

            $this->_authManager->createOperation("updateIssue", "update issue information");

            $this->_authManager->createOperation("deleteIssue", "delete an issue from a project");


            //create the reader role and add the appropriate permissions as children to this role

            $role=$this->_authManager->createRole("reader");

            $role->addChild("readUser");

            $role->addChild("readProject");

            $role->addChild("readIssue");


            //create the member role, and add the appropriate permissions, as well as both the reader role itself, as children

            $role->$this->_authManager->createRole("member");

            $role->addChild("reader");

            $role->addChild("createIssue");

            $role->addChild("updateIssue");

            $role->addChild("deleteIssue");


            //create the owner role, and add the appropriate permissions, as well as both the reader and member roles as children

            $role->$this->_authManager->createRole("owner");

            $role->addChild("reader");

            $role->addChild("member");

            $role->addChild("createUser");

            $role->addChild("updateUser");

            $role->addChild("deleteUser");

            $role->addChild("createProject");

            $role->addChild("updateProject");

            $role->addChild("deleteProject");


            //provide a messege indicating success


            echo "Authorization hierarchy successfully generated";

        }

    }

}

        

?>

But when I execute on the shell there is a error:

Problem solved

I wrote it wrong: private $authManager;

The correct: private $_authManager;

But I have a doubt:

But when I execute on the shell there is a error:

This the line 96:

[b]

?>

[/b]

After this line:




return <<<EOD

whole code becomes comment. Why?

The EOD; statement may not have any spaces in front of it. In other words, it must be at the far left of the line. Also, the stuff between return <<<EOD and EOD; will be printed as-is. So if you put spaces in front of those lines, it will show up in the console output as spaces too. Here is the getHelp() function with proper indentation.




    public function getHelp()

    {

        return <<<EOD

USAGE

rbac


DESCRIPTION

This command generates an initial RBAC authorization hierarchy.


EOD;


    }

I hope its okay that I capture this thread?

I have a similar problem, I guess.

Code in auth.php




class RbacCommand extends CConsoleCommand

{

   public function run($args)

   {

        $auth=Yii::app()->authManager;

       

   

        $auth->createOperation('createPost','create a post');

        $auth->createOperation('readPost','read a post');

[...]

When I use:

I dont know what I shall do now. I thought I start the shell, use this php file and than my DBs are filled with my roles. ;(

Hi Louis,

to run the RBAC script you have to add the path to your application config file as a commandline parameter.

The RBAC script needs access to your application config settings, in this case to the ‘authManager’ properties.

Here I attached my "RbacCommand.php" class which works fine with yii 1.1.9
