There are scenarios when you work with DVCS (like [Mercurial]( http://mercurial.selenic.com/) or [Git]( http://git-scm.com/)) and CDbMessageSource. To my experience keeping the development database and production database in sync can be very...

Yesterday I've written a module for myself. Just an experiment. When I was feeling satisfied, I've created a repository on github, and pushed my code. My module and yii are on github. So I'll show you a "new" way to start our yii projects.

Here is my experiment inspired by my own question and others from the forum.

For those who feel, the Controller->accessRules() or RBAC (Role-Based Access Control) is too complicated or doesn't want the username(s) to be hard-coded in accessRules(), here is a very simple, easy-to-implement solution.

Say, you want to write a test for a component which provides a caching feature. How would you know, that some method of your component returns a cached result? With the solution described here you can inspect all log outputs. So you could search the logs for accesses to the DB to really make sure, that the result was served from cache.

In this mini howto I would like to show how to add a required captcha field in the login form, after a defined number of unsuccessfull attempts. To do this, I will use the blog demo that you have in default Yii download package (path/to/yii/demos/blog).

I needed a csv export function for my cgridview and I wanted to export the entire result set of the sorted and filtered cgridview the user was viewing via ajax.

This article discusses the installation/configuration of the YiiBash project (https://github.com/dsoprea/YiiBash).

Let's say our table 'mug' has a column named 'color' of the type ENUM('red','green','blue').
We want to replace the textfield for the attribute color in the create and update forms of a 'mug' with a Radio Button List, which has the enum values as options.
This is a rewrite of c@cba in the wiki article of [enumDropdownList](http://www...

To use this "how-to", you need to install phing in your machine.

He im giving you a very simple example ie how you can store an image to your blob field in a table.Hope you already familiar with the normal image upload.

This is a simple example of how we can display images in CGridviews.Imagine that you have an image field in your table ie either a location field or a blob type field used to store the images.

This tutorial assumes some basic knowledge of Yii and a functional development environment.

Let's say you have an internal messaging system in your webapp, and you want to display messages dynamically and real-time to the relevant recipients.

If you need simple Role based access control without the long RBAC process then this article is just for you. Lets jump to the point.

Let's see what exactly are the events in Yii!

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

Remember-filters-gridview is one of the must-use extension on all of my project. However, it lacks of storing the page and sort variables of the grid view.

Many desktop programmers are used to having dynamic forms, where clicking on a record in a parent sub-form, updates another sub-form with the child records. While having many levels of nested sub-forms in a single view might not be such a good idea for a web application, I thought doing it one level deep might be interesting and useful. But, instead of sub-forms I used CGridViews.
