ruby on rails - How to update model attribute from Model? -


i have method change user status inside it's model, possible use inside user model:

class user < activerecord::base  def confirm!   super   self.update_column(:status => "active") end  end

i saw these 2 examples;

rails update_attribute

how update attributes in self model rails

couldn't quite 1 go with!

it depends on whether or not want validations in model run. update_attribute not run validations, update_attributes will. here couple of examples.

using update_attributes:

class user < activerecord::base   validates :email, presence: true    def confirm!     update_attributes(status: 'active')   end end

the following return false , not update record, because not email has been set:

user = user.new user.confirm! # returns false

using update_attribute:

class user < activerecord::base   validates :email, presence: true    def confirm!     update_attribute(:status, 'active')   end end

the following update status active regardless of whether or not email has been set:

user = user.new user.confirm! # returns true
