Instance Method Details

#validates_formatting_of(attribute, options = {}) ⇒ Object

Using validates_formatting_of is as simple as using Rails’ built-in validation methods in models.

class User < ActiveRecord::Base

validates_formatting_of :email, :using => :email

end

If your column name is idencital to any of the built-in methods, you may leave off the ‘:using` option and validates_formatting_of will automatically use the validation with the matching name.

class User < ActiveRecord::Base

validates_formatting_of :email

end

You can also pass conditions and options for Rails to use

  • :if

  • :unless

  • :allow_nil

  • :allow_blank

  • :on
