Yii makes it really easy for all to use their already made objects that automate everything we do. It provides also great power of flexibility and styling but hey, we programmers tend to complicate our lives and push a little more the power of our tools.
I wanted to keep all the I18N related translations in separate files, so that I would not need to modify the view files or the model files every time I need to update or fix the translations
of application's source language.
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 drop down list, which has the enum values as options.
The main code was contributed by zaccaria in the forum (see this post).
There are several methods and techniques that come handy in the case you need to call an external resource periodically or if you are waiting for a server push, but I present here an easy and straightforward one using HTML5's Server-Sent Events (SSE).
