Seed Data Corrections

Problem Identified

The "Schedule Experiment" component was showing "undefined" for soaking duration in the top right panel. This was caused by a mismatch between the database schema and frontend expectations:

• Database: Used soaking_duration_hours column
• Frontend: Expected soaking_duration_minutes field
• Seed Files: Were trying to insert into non-existent soaking_duration_minutes column

Root Cause

1. The migration 20250101000004_data_entry_tables.sql created the soaking table with soaking_duration_hours column
2. The frontend TypeScript interfaces and UI code expected soaking_duration_minutes
3. The seed files were updated to use soaking_duration_minutes but the database schema wasn't updated accordingly
4. This caused the frontend to receive undefined when trying to access soaking.soaking_duration_minutes

Solution Implemented

1. Database Schema Fix

File: supabase/migrations/20250103000001_fix_soaking_duration_column.sql

• Added soaking_duration_minutes INTEGER column
• Backfilled data from soaking_duration_hours * 60
• Updated trigger function to use minutes
• Dropped the old soaking_duration_hours column

2. Views Update

File: supabase/migrations/20250103000002_update_views_for_soaking_minutes.sql

• Updated experiments_with_phases view to use soaking_duration_minutes
• Updated repetitions_with_phases view to use soaking_duration_minutes

3. Corrected Seed Files

Phase 2 JC Experiments

File: supabase/seed_04_phase2_jc_experiments_corrected.sql

• Experiment Numbers: 0-19 (matching CSV data, not 1-20)
• Soaking Duration: Converted from hours to minutes (e.g., 34 hours = 2040 minutes)
• Air Drying Duration: Used exact values from CSV (19-60 minutes)
• JC Cracker Parameters: All parameters match CSV data exactly
• Repetitions: Each experiment has 3 repetitions as specified

Meyer Experiments

File: supabase/seed_05_meyer_experiments_corrected.sql

• Experiment Numbers: 1-40 (matching CSV data)
• Soaking Duration: Converted from hours to minutes (e.g., 27 hours = 1620 minutes)
• Air Drying Duration: Used exact values from CSV (11-56 minutes)
• Meyer Cracker Parameters: All parameters match CSV data exactly
• Repetitions: Each experiment has 1 repetition as specified

Data Mapping from CSV

Phase 2 JC Experiments (phase_2_JC_experimental_run_sheet.csv)

• Unique Experiments: 20 (numbers 0-19)
• Repetitions per Experiment: 3
• Soaking Duration Range: 10-38 hours (600-2280 minutes)
• Air Drying Duration Range: 10-60 minutes
• Machine Type: JC Cracker

Meyer Experiments (post_workshop_meyer_experiments.csv)

• Unique Experiments: 40 (numbers 1-40)
• Repetitions per Experiment: 1
• Soaking Duration Range: 10-54 hours (600-3240 minutes)
• Air Drying Duration Range: 11-56 minutes
• Machine Type: Meyer Cracker

Files Created/Modified

New Migration Files

1. supabase/migrations/20250103000001_fix_soaking_duration_column.sql
2. supabase/migrations/20250103000002_update_views_for_soaking_minutes.sql

New Seed Files

1. supabase/seed_04_phase2_jc_experiments_corrected.sql
2. supabase/seed_05_meyer_experiments_corrected.sql

Deployment Instructions

1. Run the migrations in order:

   -- First fix the column
   \i supabase/migrations/20250103000001_fix_soaking_duration_column.sql
   
   -- Then update the views
   \i supabase/migrations/20250103000002_update_views_for_soaking_minutes.sql
   

2. Clear existing data and run corrected seeds:

   -- Clear existing data (optional, use with caution)
   DELETE FROM public.experiment_repetitions;
   DELETE FROM public.jc_cracker_parameters;
   DELETE FROM public.meyer_cracker_parameters;
   DELETE FROM public.cracking;
   DELETE FROM public.airdrying;
   DELETE FROM public.soaking;
   DELETE FROM public.experiments;
   
   -- Run corrected seed files
   \i supabase/seed_04_phase2_jc_experiments_corrected.sql
   \i supabase/seed_05_meyer_experiments_corrected.sql
   

Expected Result

After applying these changes:

• The "Schedule Experiment" component will show correct soaking durations in minutes
• All experiment data will match the CSV source files exactly
• The database schema will be consistent with frontend expectations
• Phase timing calculations will work correctly

Verification

To verify the fix:

1. Check that soaking.soaking_duration_minutes is populated in the database
2. Verify the Schedule Experiment UI shows durations like "2040min" instead of "undefined"
3. Confirm experiment numbers match the CSV files (0-19 for JC, 1-40 for Meyer)
4. Validate that all machine parameters match the CSV data
