Login Error in YII Framework

Question

I am new to the beautiful Yii Framework. So I am just going through the tutorials and documentation. So I am doing the blog tutorial from starting. So for blog application I made export the database from the blog folder which comes with Yii to MySQL. Again I decided to use Yii User module and for that I made export the user module database to MySQL. Now my problem is that when I am using login in the application it is showing some error like this

Trying to get property of non-object

I both tried index.php?r=site/login and also index.php?r=user/login both failed. So can some one tell me how to solve this. FYI in my database there are two fields like 'ia_user' which is imported from the blog folder and 'ia_users' which is imported from the Yii User module folder. So is there any thing wrong. Below I am pasting the configuration of main.php file.

<?php

// uncomment the following to define a path alias
// Yii::setPathOfAlias('local','path/to/local-folder');

// This is the main Web application configuration. Any writable
// CWebApplication properties can be configured here.
return array(
  'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
  'name'=>'My Blog Application',

  // preloading 'log' component
  'preload'=>array('log'),

  // autoloading model and component classes
  'import'=>array(
    'application.models.*',
    'application.components.*',
    /*user module starts here*/
    'application.modules.user.models.*',
    'application.modules.user.components.*',
    /*user module ends here*/
  ),

  'modules'=>array(
    // uncomment the following to enable the Gii tool
    /*

       // If removed, Gii defaults to localhost only. Edit carefully to taste.
      'ipFilters'=>array('127.0.0.1','::1'),
    ),
    */
  ),

  // application components
  'components'=>array(
    'user'=>array(
      // enable cookie-based authentication
      'allowAutoLogin'=>true,

      'loginUrl' => array('/user/login'),
      /*user module ends here*/
    ),
    // uncomment the following to enable URLs in path-format

    ),

    ),

          'levels'=>'error, warning',
        ),
        // uncomment the following to show log messages on web pages
        /*
        array(
          'class'=>'CWebLogRoute',
        ),
        */
      ),
    ),
  ),

  // application-level parameters that can be accessed
  // using Yii::app()->params['paramName']
  'params'=>array(
    // this is used in contact page
    'adminEmail'=>'webmaster@example.com',
  ),
);

Answer 1

I had to add user in array of modules just like this

'user'=>array(
         'user'
      // enable cookie-based authentication
      'allowAutoLogin'=>true,
      /*user module starts here*/
      'loginUrl' => array('/user/login'),
      /*user module ends here*/
    ),
