如何在Rails日志中包含devise用户名（使用graylog2）

Question

Is there a way to include the logged in user in rails logs? I am using devise and graylog2, the latter of which I assume is inconsequential to the answer.

Answer 1

Devise provides a current_user helper in the controller which can be used to access the currently signed-in user.

Assuming the user model has a name attribute, you can do the following:

::Rails.logger.info "The currently logged-in user is #{current_user.name}"
