I've wanted to add an automatic remember_me for Devise by default (without a checkbox). First I've tried to do something like this:
def create params[:user].merge!(remember_me: true) super end
Unfortunately it doesn't seem to work. I have a rememberable strategy included in my User model, but still, remember_user_token cookie was not created. I don't know why, even with remember_me option provided, it sets it to false. The easiest (and working) way to fix this, is to overwrite remember_me method, so it will always return true value.
# User of our portal class User < ActiveRecord::Base devise :database_authenticatable, :trackable, :encryptable, :confirmable, :recoverable, :registerable, :validatable, :lockable, :rememberable # @return [Boolean] user should be remembered when he logs in (with cookie) # so he won't be asked to login again def remember_me true end end
To be honest I didn't have time to investigate it more deeply, so maybe there's a better solution but this one works. After that, remember_user_token cookie is created and the session isn't lost after user closes his browser.
