From 434985b1eac385a2cd1b4196bce8f717b1501acd Mon Sep 17 00:00:00 2001 From: Javi R <4920956+rameerez@users.noreply.github.com> Date: Mon, 9 Feb 2026 23:53:01 +0000 Subject: [PATCH] =?UTF-8?q?Fix=20bugs,=20DRY=20up=20code,=20and=20optimize?= =?UTF-8?q?=20dashboard=20performance=20(~176=20=E2=86=92=2038=20queries)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Bug fixes: - Fix calculate_new_mrr_in_period using overly permissive status filter (where.not excluded+churned let through incomplete/unpaid; now uses where(status: 'active') to match MrrCalculator logic) - Fix calculate_new_subscribers inconsistency (wasn't filtering excluded statuses; now delegates to calculate_new_subscribers_in_period) - Move EXCLUDED_STATUSES/CHURNED_STATUSES to module level so MrrCalculator can reference them as Profitable::EXCLUDED_STATUSES - Use shared Profitable::EXCLUDED_STATUSES constant in MrrCalculator instead of hardcoded array DRY consolidation: - calculate_churn delegates to calculate_churn_rate_for_period - calculate_churned_customers delegates to calculate_churned_subscribers_in_period - calculate_churned_mrr delegates to calculate_churned_mrr_in_period - calculate_new_mrr delegates to calculate_new_mrr_in_period - calculate_new_subscribers delegates to calculate_new_subscribers_in_period - Add subscriptions_with_processor helper to avoid repeating .includes(:customer).select(...).joins(:customer) Dashboard performance optimization: - Batch monthly_summary: 72 queries → 5 (bulk load all subscription data for full 12-month range, group by month in Ruby) - Batch daily_summary: 60 queries → 2 (same pattern for 30 days) - Add period_data method: computes all period metrics in one pass, reusing intermediate values (9 → 6 queries per period) - Move all computation from view to controller (precompute as instance variables, eliminating duplicate mrr_growth_rate calls) - Verified on LicenseSeat: 38 queries, 2 cached, 71ms total New features: - monthly_summary(months:) and daily_summary(days:) public methods - period_data(in_the_last:) public method returning hash of NumericResult values (new_customers, churned_customers, churn, new_mrr, churned_mrr, mrr_growth, revenue) Test sync & coverage: - Full sync of test_helper.rb Profitable module with production code - 14 new tests (monthly_summary, daily_summary, period_data, new_subscribers filtering) - 249 tests, 382 assertions, 0 failures, 94.64% coverage Co-Authored-By: Claude Opus 4.6 --- .../profitable/dashboard_controller.rb | 20 +- app/views/profitable/dashboard/index.html.erb | 169 +++++++++- lib/profitable.rb | 304 +++++++++++++---- lib/profitable/mrr_calculator.rb | 2 +- test/profitable_test.rb | 245 ++++++++++++++ test/test_helper.rb | 317 ++++++++++++++---- 6 files changed, 899 insertions(+), 158 deletions(-) diff --git a/app/controllers/profitable/dashboard_controller.rb b/app/controllers/profitable/dashboard_controller.rb index 8ac1c2f..38d6efd 100644 --- a/app/controllers/profitable/dashboard_controller.rb +++ b/app/controllers/profitable/dashboard_controller.rb @@ -1,12 +1,24 @@ module Profitable class DashboardController < BaseController def index - end + @mrr = Profitable.mrr + @mrr_growth_rate = Profitable.mrr_growth_rate + @total_customers = Profitable.total_customers + @all_time_revenue = Profitable.all_time_revenue + @estimated_valuation = Profitable.estimated_valuation + @average_revenue_per_customer = Profitable.average_revenue_per_customer + @lifetime_value = Profitable.lifetime_value - private + @show_milestone = @mrr_growth_rate > 0 + @milestone_message = Profitable.time_to_next_mrr_milestone if @show_milestone - def test - end + @monthly_summary = Profitable.monthly_summary(months: 12) + @daily_summary = Profitable.daily_summary(days: 30) + @periods = [24.hours, 7.days, 30.days] + @period_data = @periods.each_with_object({}) do |period, hash| + hash[period] = Profitable.period_data(in_the_last: period) + end + end end end diff --git a/app/views/profitable/dashboard/index.html.erb b/app/views/profitable/dashboard/index.html.erb index 3ba78e9..65feff1 100644 --- a/app/views/profitable/dashboard/index.html.erb +++ b/app/views/profitable/dashboard/index.html.erb @@ -1,4 +1,9 @@ + + + + + + + + + + + + + <% @monthly_summary.reverse.each do |month_data| %> + + + + + + + + <% end %> + +
