Customizing Validation Method

If you want to create your own validation method, you must create the validation class.

You can create your validation class via commandline.

Firstly you need to created the file named "ichi" under your project folder and use the below code in this file

And then you can create the validation class in your commandline

The default file folder is "app/Validations". So after making command, the validation class you created will be in the this default file folder. If you want to change the default folder path, you can change it in your "ichi" file.

You must set the accepted validation rules in your created validation class. Let's make to accept only over age 21 in this created class to validate.

In calling your validation class

It is the validation data field name. For the example, it is 'age'.

It is the data value. For the example, it is the value of 'age' request.

You can pass other values in the constructor.
