mysql - ActiveRecord SQL queries not getting logged -


i have been facing weird problem time, wherein activerecord queries not getting logged in terminal, or in rails console (using activerecord::base.logger = logger.new(stdout)).

this exception get:

could not log "sql.active_record" event. nameerror: undefined  local variable or method `s'  # activesupport::notifications::event:0x007f9ae02a60c0.

i tried out few things, including reinstalling rails, no avail.

apart wondering why happening, i’m unable check actual sql queries fired against database result.

i ran similar ways back.

i able fix adding

# config/environments/development.rb config.logger = logger.new(stdout)

and 

# config/environment.rb # prevent log buffering $stdout.sync = true
