Rails 4 + Devise: sign_in(user) method not working, does not set current_user

Question

I'm working on a checkout for a store. When the form is submitted, this action takes place in my controller ``` def update_billing ... if @checkout.save sign_in(guest_user) #<-- redirect_to root_path, notice: "Success!" else render 'billing' end end ``` I test this by `raise`ing inside the action and testing it out using better_errors: ``` >> sign_in(guest_user) if params[:checkout_form][:create_an_account] == "1" => # >> current_user => #

Accepted Answer

I figured it out. In my `@checkout` form object, I update the `guest_user`s attributes and save it when I call `@checkout.save`. I think devise has to sign in the most recent version of guest_user, so I had to add a `guest_user.reload` before `sign_in(guest_user)`

In short, reload your user (`user.reload`) before signing it in.
