= QueryTrace plugin for Rails It's nice that ActiveRecord logs the queries that are performed when your actions are executed, since it makes it easy to see when you have serious inefficiencies in your application. The next question, though, is always, "OK, so where are those being run from?" Before QueryTrace, that question could be a real pain to answer, since you'd have to go trawling through your code looking for the culprit. Once you have QueryTrace installed, though, your logs won't just tell you that you have a problem, they will pinpoint the location of that problem for you. == Usage All you have to do is have the plugin installed - QueryTrace takes care of the rest, including: * Only displaying when at the DEBUG log level * Honoring your log colorization settings == Example Before: Schedule Load (0.023687) SELECT * FROM schedules WHERE (schedules.id = 3) LIMIT 1 Resource Load (0.001076) SELECT * FROM resources WHERE (resources.id = 328) LIMIT 1 Schedule Load (0.011488) SELECT * FROM schedules WHERE (schedules.id = 3) LIMIT 1 Resource Load (0.022471) SELECT * FROM resources WHERE (resources.id = 328) LIMIT 1 After: Schedule Load (0.023687) SELECT * FROM schedules WHERE (schedules.id = 3) LIMIT 1 app/models/available_work.rb:50:in `study_method' app/helpers/plan_helper.rb:4:in `work_description' app/views/plan/_resource_schedule.rhtml:27:in `_run_rhtml_plan__resource_schedule' app/views/plan/_resource_schedule.rhtml:24:in `_run_rhtml_plan__resource_schedule' app/views/plan/_schedule_listing.rhtml:5:in `_run_rhtml_plan__schedule_listing' app/views/plan/_schedule_listing.rhtml:3:in `_run_rhtml_plan__schedule_listing' app/views/plan/_schedule_listing.rhtml:1:in `_run_rhtml_plan__schedule_listing' app/views/plan/index.rhtml:6:in `_run_rhtml_plan_index' vendor/plugins/textmate_footnotes/lib/textmate_footnotes.rb:60:in `render' Resource Load (0.001076) SELECT * FROM resources WHERE (resources.id = 328) LIMIT 1 app/models/available_work.rb:54:in `div_type' app/helpers/plan_helper.rb:6:in `work_description' app/views/plan/_resource_schedule.rhtml:27:in `_run_rhtml_plan__resource_schedule' app/views/plan/_resource_schedule.rhtml:24:in `_run_rhtml_plan__resource_schedule' app/views/plan/_schedule_listing.rhtml:5:in `_run_rhtml_plan__schedule_listing' app/views/plan/_schedule_listing.rhtml:3:in `_run_rhtml_plan__schedule_listing' app/views/plan/_schedule_listing.rhtml:1:in `_run_rhtml_plan__schedule_listing' app/views/plan/index.rhtml:6:in `_run_rhtml_plan_index' vendor/plugins/textmate_footnotes/lib/textmate_footnotes.rb:60:in `render' Schedule Load (0.011488) SELECT * FROM schedules WHERE (schedules.id = 3) LIMIT 1 app/models/available_work.rb:50:in `study_method' app/helpers/plan_helper.rb:4:in `work_description' app/views/plan/_resource_schedule.rhtml:27:in `_run_rhtml_plan__resource_schedule' app/views/plan/_resource_schedule.rhtml:24:in `_run_rhtml_plan__resource_schedule' app/views/plan/_schedule_listing.rhtml:5:in `_run_rhtml_plan__schedule_listing' app/views/plan/_schedule_listing.rhtml:3:in `_run_rhtml_plan__schedule_listing' app/views/plan/_schedule_listing.rhtml:1:in `_run_rhtml_plan__schedule_listing' app/views/plan/index.rhtml:6:in `_run_rhtml_plan_index' vendor/plugins/textmate_footnotes/lib/textmate_footnotes.rb:60:in `render' Resource Load (0.022471) SELECT * FROM resources WHERE (resources.id = 328) LIMIT 1 app/models/available_work.rb:54:in `div_type' app/helpers/plan_helper.rb:6:in `work_description' app/views/plan/_resource_schedule.rhtml:27:in `_run_rhtml_plan__resource_schedule' app/views/plan/_resource_schedule.rhtml:24:in `_run_rhtml_plan__resource_schedule' app/views/plan/_schedule_listing.rhtml:5:in `_run_rhtml_plan__schedule_listing' app/views/plan/_schedule_listing.rhtml:3:in `_run_rhtml_plan__schedule_listing' app/views/plan/_schedule_listing.rhtml:1:in `_run_rhtml_plan__schedule_listing' app/views/plan/index.rhtml:6:in `_run_rhtml_plan_index' vendor/plugins/textmate_footnotes/lib/textmate_footnotes.rb:60:in `render' == Additional Info Author: Nathaniel Talbott (for Terralien) Contact: nathaniel@talbott.ws License: MIT Home: http://github.com/ntalbott/query_trace/ Subversion mirror: https://terralien.devguard.com/svn/projects/plugins/query_trace Copyright (c) 2006 Nathaniel Talbott.
