This is a reference to be used for Model rule validation and is compiled from the Yii documentation and code. The purpose is to have all the information gathered in one place instead of scattered. This reference is not an intro. See The Definitive Guide to Yii, Declaring Validation Rules for a tutorial.
Suppose to have two models: Users and Emails. You do not want to store email in a Users model. And User can have 0 or many emails. This is the form generated to create a new user (just username).
Relational databases do not support inheritance so if we need to represent it, we have to somehow store meta info while keeping performance by minimizing JOINs. One way to solve this problem is using single table inheritance. All fields for the whole class tree are stored in a single table. Class name is stored in the type field...
In yii2 we can create form without create FormModel. Here we go
Working with scenarios, with models that can receive many modifications in their rules or structures as development evolves, can create disruptions in the rescue process.
Suppose you have an Application in Yii that manages hotels each one has many customers.
In this wiki I will show you how to save/update a model with many related model For example: How to set a product to multiple categories only in one post form ?
I ran into a problem and on irc we worked it out. Since there is a lack on information on filters in genral i thought i'd start sharing all my findings, might be usefull for other people.

This tutorial shows you how to safely remove records between relationships.
There are cases that model validators should be depended by controller/action and you couldn't manipulate on the model class or using scenarios in easy way
/*
Get class constants by token.
If you set constants with same prefix, like:
MY_STATUS_1
MY_STATUS_2
MY_STATUS_3
The yii2-field-range extension enables you to easily setup ActiveField range fields with Bootstrap styling. You basically can setup two attributes joined together like a single field with combined validation error block.
Everyone have seen a multilayer menu in several CMS
There are cases you want to update a record on CGridview directly
Note the tag {{homeUrl}} will be dynamically replaced at runtime.
I just chased my tail around for a bit today. I got lost with setting the status of all inputs, and banging my head on why the "validate" function just wasn't working.
This is a reference about model validators and user roles. In many cases we want model validators to applied only for some privileged users or not
Suppose you have Products,Categories and each product belongs in many categories
There are cases that you want to validate the file format, size, extension etc but how to do that without submit the form ?
