Queries Watch

An overview of the number of queries is output to the log and browser console.

log/development.log:

Queries total_count: 5, cached_count: 0, exec_count: 5, total_duration: 4.4ms

Browser console:

In app/views/layout/application.html.haml:

!!!
%html
  %head
    %title MyAPP
    = favicon_link_tag '/favicon.ico'
  %body
    = yield
    - if Rails.env.development?
      = queries_watch_summary

Add this line to your application's Gemfile:

gem 'queries_watch', group: 'development'

And then execute:

$ bundle

In config/initializers/queries_watch.rb, you can configure the following values.

if Rails.env.development?
  QueriesWatch.configure do |config|
    config.warn_threshold = 30 # default: nil
    config.error_threshold = 100  # default: nil
  end
end
