As we know Using crud generator creates menu items in view files (for each view file have a varius menu items)

Just thought I would share this bash script I wrote to help automate a base install of YII on an Ubuntu server. This script does the following:

So you want to use CForm (form builder), but need to preload dropdowns in a form? It's simpler than it seems.
You got your CFormModel, CForm and the actual Form, right?
Let's say you have the typical State -> City dependent dropdowns, so you would want to load the from with the State and City selected.

It can happen that you work in development environment and you make changes to database tables structures, adding tables, or changing fields.

namespace app\components;

1. Create an Active Record Behavior that builds the criteria for the search() method and attach it to your model
2. Modify the search() method of the model to merge the behavior's criteria in with the rest of the searchable attributes

} ` V. The Order model would start with:

class Order extends CActiveRecord
{
	const STATUS_INITIATED = 1;
	const STATUS_CANCELED = 2;
	const STATUS_EXPIRED = 3;
	const STATUS_PAID = 4;
	public $statuses = array(
		self::STATUS_INITIATED => 'Initiated',
		self::STATUS_CANCELED => 'Canceled',
		self::STATUS_EXPIRED => 'Expired',
		self::STATUS_PAID => 'Paid',
	);
// more cod...

$this->render('index', array( 'dataProvider' => $dataProvider, )); `

Taking futher the idea from Piotr Masełkowski - http://www.yiiframework.com/extension/elipsum/ here's how to generate multilanguage Lorem Ipsum text. This example uses English and Bulgarian sample paragraphs. Create a class in /protected/components/LoremIpsum.php. Wall of text incoming wohoo...

Yii 2.0 comes with a formatter component to format dates, numbers, and other values for international users according to their locale. This is very useful for displaying data. When working with incoming data or when using enhanced input methods like the [MaskedInput widget](https://www.yiiframework.com/doc/api/2.0/yii-widgets-maskedinp...

Example settings when using Gettext for i18n.

When one needs to select a record in a table that do not have related records through a relation, it is generally suggested to use a subquery. Personnaly, I prefer a high level approach, and I have a method to do it with scopes.

Note: Before reading this wiki you should have read the caching part in the Yii guide

in model add the following code:

yii rights some tips..

According to below wiki we could migrate database schema to another database

Suppose we want to set a category to product (or an item in general term), Also suppose categories has sub-categories (multi-level)

If you have two datepicker in one form and you want that a date of from date shold be minimum date of todate then put following code in Cjuidatepicker widget options array:

'onSelect'=>'js:function(selected) {
$("#HostelRoomStatusMaster_room_status_master_end_date").datepicker("option","minDate",selected);
				}',

The problem is not new: after setting some filters in a grid (typically in admin view), and gone to another page, returning in the grid's page I would like to find the filters with previous setting mantained.
