Tournament & League Templates — Spin Up Recurring Events in 10 Seconds

Save any finished tournament or league as a reusable template. Spin up new instances with name + start date — every other config decision copies over. Personal vs. club-shared visibility, library at Programs → Templates, and a Start-from-a-template picker on New Tournament. This update is designed for club managers who want a better club operations experience — less manual work, more control, and a smoother workflow.

What's Included

Save as template button on every tournament & league admin page (show, edit) and the index 3-dots menu

Re-save flow detects an existing template from the same source and offers Update existing / Save as new — never silent duplicates

Personal templates are private to the creator; Club-shared templates are visible to every admin of the club

Templates library at /club_admin/:club_id/templates with three tabs (Tournaments / Leagues / Events) and per-card usage_count + last-used date

Click Use on any card → modal collects name + start date → POST /instantiate → redirect to the new event's edit page in seconds

Start-from-a-template picker appears at the top of New Tournament — skips the form entirely when you have at least one accessible template

Time offsets are relative — a division scheduled 2h after the earliest in the template stays 2h after the new anchor, regardless of your new start time

Caps: 100 templates per club, 50 personal templates per user — no runaway library growth

Atomic usage_count increment (DB-level UPDATE, no Ruby-side race) + last_used_at on every instantiation

Soft-fails on missing locations: instantiate without a location and let the operator pick one in the editor

Platform-owner dashboard at /platform_owner/templates_dashboard surfaces total templates, total instantiations, adopting clubs, and the top templates by usage

Demo seed mints 3 tournament + 3 league templates per club so the library has realistic content on a freshly-reset demo

Full TDD: 80+ specs across services, requests, system, and demo-seed coverage. Two end-to-end Capybara flows verify the JS glue.
