How do you add validations to devise?

I would like to add validations to the info of the tables of the user. E.G. email 开发者_开发问答must be with 6..20 or whatever How do I add these to the Devise gem?

I know that the use is with :validatable, however i'm not sure what the options are.

should I add normal validations `validates

Answer are written here.

In a nutshell:

• to interact with devise columns, edit this file: /config/initalizers/devise.rb

• otherwise, just add your column as attr_accessible and write your normal validations.
