Git Pull Error - There is no tracking information for the current branch

Usually I can just do a git pull to get the latest update from master. However, I receive the following error/warning when I try to do git pull.

To solve this, I need to do "git pull origin master"

D:\xampp\htdocs\website>git pull
remote: Counting objects: 5, done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 3 (delta 2), reused 0 (delta 0)
Unpacking objects: 100% (3/3), done.
   25bc2eb..0b66cee  master     -> origin/master
There is no tracking information for the current branch.
Please specify which branch you want to merge with.
See git-pull(1) for details

    git pull <remote> <branch>

If you wish to set tracking information for this branch you can do so with:

    git branch --set-upstream-to=origin/<branch> master

Alias "{alias}" is invalid. Make sure it points to an existing PHP file and the file is readable.

The following error occur on my Yii web app
Alias "ext.dropdown.DropDownBox" is not valid.  Make sure it points to an existing PHP file and the file is readable.
I have checked that all of the permission is readable. This error only occurs in production and not in our test environment (mac and windows).
It turns out that our prod environment is using Centos and in my code I call
"$this->widget('ext.dropdown.DropDownBox', array(..." which should have been
"$this->widget('ext.dropDown.DropDownBox', array(..." 
Centos is very strict on case sensitivity. My extension folder name is with capital D "dropDown" and therefore I should have called the extension with capital D.

Jenkins fecthing upstream git changes take forever

Fetching upstream changes from origin

It just never ends

To solve this:

1. Go to your jenkins server
2. Go to jenkins workspace and do git pull
The authenticity of host ' (' can't be established.
RSA key fingerprint is 6e:a3:e2:b5:b4:9f:02:4c:35:50:4f:8f:52:57:2b:d0.

The reason jenkins does not work is because git is asking whether you want to add the rsa key fingerprint. You need to do this once manually and after that jenkins will be able to do the git pull for you.

Yii Require Once Error Cpanel

I tried to install Yii the first time on my cpanel hosting. However, when I try to launch my website I got the following errors:

Warning: require_once(/home/user_name/public_html/yii/demos/your_app/../../YII/framework/yii.php) [function.require-once]: failed to open stream: No such file or directory in /home/user_name/public_html/yii/demos/your_app/index.php on line 12

Fatal error: require_once() [function.require]: Failed opening required '/home/user_name/public_html/yii/demos/your_app/../../YII/framework/yii.php' (include_path='.:/usr/lib/php:/usr/local/lib/php') in /home/user_name/public_html/yii/demos/your_app/index.php on line 12

However, when I try the Yii demo apps like hangman, it works.

So I copied yii/demos/hangman/index.php to your_app/index.php file and it works. The reason I got the above error is because the yii path on my cpanel is different than on my local.

My cpanel index.php (I install yii on my public_html/yii)


// change the following paths if necessary

// remove the following line when in production mode
// defined('YII_DEBUG') or define('YII_DEBUG',true);

Yii Active Records

Yii Active Record


//Assuming we have a database table with ID, title, content, category_id and user_id as a field

public function actionActiveRecord()
  //example of what Yii Active record can return
  $model = Post::model()->find('id = 1');
  echo $model->title;
  $model = Post::model()->find('category_id = 2 AND user_id = 1');
  echo $model->title;

  //alternatively you can use Yii Active record find by attributes
  $model = Post::model()->findByAttributes(array(
      'category_id' => 2,
      'user_id'     => 1,
  echo $model->title;

  //or you can use findByPk
  $model = Post::model()->findByPk(1)

  //if you need to display more than 1 data findAll
  $model = Post::model()->findAll('category_id = 2');
  foreach($model as $m){
    echo $m->title."<br/>";
    echo $m->content."<br/>";
