CHtml::ajaxLink(), CHtml::ajaxSubmitButton() and similar methods are great, but if they are located inside a portion of the page that is already loaded via ajax something bad will happen, something you may even not notice if you are not using tools like firebugs...
I've seen many tickets regarding how to show friendly delete confirmation using CGridView's CButtonColumn in ajax request. If you are using relational database, after producing CRUD functionality when you try to delete a record in ajax mode which has child record it can't be deleted and you can see the ajax loader forever. By this way you can't show the users if a record has been successfully dele...
First param in CActiveDataProvider could be a string with model name or instance of class. So, you may use CActiveRecord::cache() for cache, but you need set third param to 2, because you should cache 2 queries: counting and get data.
For best experience,use Chrome.Other browsers may complain here and there.Sorry,no patience to make happy every freaking browser out there!
Here are all wiki articles from "Understanding" series by Yii wiki contributors:
I've found useful to have a step by step reference guide to work with Git with most used commands, feel free to update it with useful information you may find interesting too.
With Yii you can use one CActiveForm for collecting data for two or more models with ajax validation and client validation.
The popular [CListView] and [CGridView] widgets each take a data provider and iterate over each data object produced, calling the user's code to render each row one at a time, and most are familiar with the use of the $data variable to represent the current model object or array.
There are situations in which Active Record will generate nonsense queries from what a nieve Yii user might think is reasonable code. One such situation is a CActiveDataProvider using CDbCriteria to get data from parent and 1:n child table with a condition on the child table.
Application configuration determines how an Yii application should behave, because it is the only parameter passed in the entry script. An application, on the other hand, needs to behave differently under different circumstances. For example, an application may need different configurations when running in production mode, development mode and testing mode; In a team development environment, each...
If you like the things to be short and clear, then you can skip right to a short summary of instructions at the end of this article.

In this article, we introduce an approach that allows automatic hyphenation of the route part in URLs.
Update: This wiki has been rewritten to be in line with Yii 1.1.14. Since many of the detailed complexities are now handled by Yii, the article focuses on how the crypt() built-in function works and why it's important to use it correctly.
So here is my complete solution - note that I'm using the 'short' date format throughout.
This is second article with my tutorial. I had to add it, because Wiki article has limited length and as I was extending it's text, older paragraphs were disappearing. So here I am starting from chapter 6.
This tutorial will show you how to create Ajax dialog which allows to create new model, update or delete existing model. It works with simple links, CGridView button column links, adds a minimal amount of code and degrades gracefully with JavaScript turned off.
