在为Devise中的用户做手动sign_in时，你怎么设置记住我是？

Question

In Devise , I'm signing in my user like this:

sign_in_and_redirect(:user, user)

In the default sign in page, there's a checkbox that the user can select so that they don't have to sign in again when they return to the site. But when you do the sign in with the sign_in_and_redirect(:user, user) line, I can't work out how to set that parameter to yes. Does anyone know how? Thanks for reading.

Answer 1

Did some testing. Presenting the findings for others.

The simplest solution, assuming the user object has the rememberable module defined on the devise declarable, is to set remember_me to true on the user before sign in and redirect:

@user.remember_me = true
sign_in_and_redirect(@user, :event => :authentication)

Answer 2

current_user.remember_me!
