UserSession.find returns nil after changing password

问题

I recently created a way to change the current user password, however after saving the record, my UserSession.find returns nil, I tried by writing UserSession.new({...}).save with no luck, any suggestion on how to resolve this issue?

Here is my code, notice that is run through an AJAX request (this is a method under UserSessionController):

def

 change_my_password
    #print "--------------RECORD: #{current_user_session.record.as_json}-------- #{current_user_session.user.as_json}"
    user = current_user
    user_email = user.email
    user_remember_me = user.remember_created_at
    response = {
      :success => false,
      :message_code => Extjs::MessageCodes::ERROR,
      :message => 'Si è verificato un errore',
      :total => 0,
      :root => []
    }
    if user.valid_password?(params[:old_password], true)
      user.password = params[:new_password]
      user.password_confirmation = params[:confirm_password]
      response[:message] = 'La nuova password e la conferma non coincidono o sono troppo brevi'
      if user.save
        response[:success] = true
        response[:message_code] = Extjs::MessageCodes::SUCCESS
        response[:message] = 'Password modificata con successo'
      end
    else
      response[:message] = 'La password precedente non coincide con quella attualmente in uso'
    end

    respond_to do |format|
      format.extjson { render :json => response }
    end
  end

回答1:

Ensure that you haven't set the maintain_sessions parameter to false, i.e.:

acts_as_authentic do |c|
  c.maintain_sessions = false # change this to true.
end

Update the session manually after save:

user.send(:update_sessions)

Recreate the session after the save:

UserSession.create(user)

Actually I didn't find a solution to this issue: I solved by forcing a login again after changing password (whcih is even added security, so not that bad).

I think KandadaBoggu is right with his answer, but I tested all of them and they are not working for me.

Maybe it's an issue created by something wrong in my code, I really don't know. At the moment I just consider this as the solution because it's actually working for my software.

If a better answer is found, I would be happy to mark it.

Thanks to everyone.
