Hello.

Where to look for a solution to this problem (The "dataProvider" property cannot be empty.) in project files ?

Usually you have to look in the action called in the controller, and you have to have something like this:




//for example: action is index and model is Menus

public function actionIndex()

{

	$dataProvider=new CActiveDataProvider('Menus');

	$dataProvider->setPagination(false);

	$this->render('index',array(

		'dataProvider'=>$dataProvider,

	));

}

hmm very interesting

in actionView() have




public function actionView() {

        $issueDataProvider = new CActiveDataProvider('Issue', array(

            'criteria' => array(

                'condition' => 'project_id=:projectId',

                'params' => array(':projectId' => $this->loadModel()->id),

            ),

            'pagination' => array(

                'pageSize' => 1

            ),

        ));


        $this->render('view', array(

            'model' => $this->loadModel(),

            'issueDataProvider' => $issueDataProvider,

        ));

    }

in actionIndex() have




public function actionIndex() {

        $dataProvider = new CActiveDataProvider('Project');

        $this->render('index', array(

            'dataProvider' => $dataProvider,

        ));

    }

What i do bad in rbac

firstly i created tables from example.

second change in config/main.php in modules




'authManager' => array(

            'class' => 'CDbAuthManager',

            'connectionID' => 'db',

        ),

then in commands create shell/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.

    }


    /**

     */

    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 con-figured to use this command.\n";

            echo "If you already added 'authManager' component in application con-figuration,\n";

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

            return;

        }


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

        echo "This command will create three roles: Owner, Member, and Reader and the following premissions:\n";

        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 indicated yes to the above question

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

            //first we need to remove all operations, roles, child relationship and as-signments

            $this->_authManager->clearAll();


            //create the lowest level operations for users

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

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

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

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

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

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


            //create the lowest level operations for issues

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

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

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

            $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 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 message indicating success

            echo "Authorization hierarchy successfully generated.";

        }

    }


}


?>

and then get shell

rbac -> Yes

get Authorization hierarchy successfully generated.

But tables empty :( What i do wrong ?

I think you should have created a new topic cause you are veering off from the original problem.
