just started to use the laravel framework development, or rookies ~ a lot of do not quite understand, at present to do a function, customized a form verification class file ~ ~ for example, I am now a member module, my member controller can have many ways to use this member form verification class verification file, I would like to ask this form verification class can be divided into scenarios to verify it? Just like the TP framework, it can be divided into this field in the model until I add it, and I only validate that field when I do the editing function. A scene like this?
