Planning Center Calendar Data Model

This document provides complete documentation of the Planning Center Calendar data model in Parable, including all tables, fields, and relationships.

Overview

The Calendar module contains 22 entity tables and 6 relationship tables supporting event management, resource booking, scheduling, and calendar synchronization.

Key Relationships Explained

Event Hierarchy:

EVENT is the master event (e.g., “Sunday Service”)
EVENT_INSTANCE is a specific occurrence (e.g., “Sunday Service on Jan 15, 2024”)
EVENT_TIME breaks instances into periods (Setup 8am-9am, Event 9am-11am, Teardown 11am-12pm)

Resource Booking:

RESOURCEs are bookable items (rooms, equipment, vehicles)
RESOURCE_FOLDERs organize resources hierarchically
RESOURCE_BOOKING links resources to event instances
ROOM_SETUP defines different configurations for room resources

Approval Workflow:

EVENT_RESOURCE_REQUEST initiates booking request
REQUIRED_APPROVAL specifies which groups must approve
RESOURCE_APPROVAL_GROUP contains approvers
RESOURCE_QUESTION collects additional information during booking

Conflict Management:

CONFLICT tracks resource double-bookings
Links winner (approved booking) and loser (rejected booking)
Resolved when winner is selected

Cross-App Connections:

EVENT_CONNECTION links calendar events to other Planning Center modules
Connected to Services (worship plans), Groups (group events), etc.
Enables unified scheduling across the platform

Generic Relationship Pattern:

Event metadata via calendar_events_relationships

Query Requirements

Schema Prefix

IMPORTANT: All tables in the Planning Center Calendar module are in the planning_center schema. You MUST prefix all table names with planning_center. in your queries. ✅ CORRECT: SELECT * FROM planning_center.calendar_events ❌ INCORRECT: SELECT * FROM calendar_events

Row Level Security (RLS)

This database uses Row Level Security (RLS) to automatically filter data based on:

tenant_organization_id: You only see data for your current organization
system_status: You only see ‘active’ records by default

DO NOT add these filters to your WHERE clause - they are applied automatically:

❌ WHERE tenant_organization_id = 1 (unnecessary)
❌ WHERE system_status = 'active' (unnecessary)

The RLS policies ensure you only access data you’re authorized to see, making these filters redundant and potentially causing performance issues.

Common Query Patterns

Getting Events with Tags

-- CORRECT: Schema prefix included, no manual RLS filters
SELECT
    e.*,
    STRING_AGG(t.name, ', ') as tags
FROM planning_center.calendar_events e
LEFT JOIN planning_center.calendar_events_relationships er
    ON e.event_id = er.event_id
    AND er.relationship_type = 'Tag'
LEFT JOIN planning_center.calendar_tags t
    ON er.relationship_id = t.tag_id
GROUP BY e.id, e.event_id;

Finding Available Resources

SELECT r.*
FROM planning_center.calendar_resources r
WHERE NOT EXISTS (
        SELECT 1
        FROM planning_center.calendar_resource_bookings rb
        WHERE rb.resource_id = r.resource_id
            AND rb.starts_at < '2024-01-15 14:00:00'
            AND rb.ends_at > '2024-01-15 12:00:00'
    );

Detecting Booking Conflicts

SELECT
    rb1.resource_booking_id as booking1,
    rb2.resource_booking_id as booking2,
    r.name as resource_name
FROM planning_center.calendar_resource_bookings rb1
JOIN planning_center.calendar_resource_bookings rb2
    ON rb1.resource_id = rb2.resource_id
    AND rb1.resource_booking_id < rb2.resource_booking_id
    AND rb1.starts_at < rb2.ends_at
    AND rb1.ends_at > rb2.starts_at
JOIN planning_center.calendar_resources r
    ON rb1.resource_id = r.resource_id
;

Today’s Schedule

SELECT
    e.name as event_name,
    ei.starts_at,
    ei.ends_at,
    ei.location
FROM planning_center.calendar_events e
JOIN planning_center.calendar_event_instances ei
    ON e.event_id = ei.event_id
    AND (
        DATE(ei.starts_at) = CURRENT_DATE
        OR (ei.all_day_event = true
            AND DATE(ei.starts_at) <= CURRENT_DATE
            AND DATE(ei.ends_at) >= CURRENT_DATE)
    )
ORDER BY ei.starts_at;

Data Integrity Rules

Schema Qualification: Always use planning_center. prefix for all table references
Row Level Security: RLS automatically handles multi-tenancy and status filtering - do not add manual filters
Monetary Values: Resource fee and cost columns are stored in cents - divide by 100.0 for display
Time Windows: Use starts_at/ends_at comparisons and the all_day_event flag rather than relying on system_status
Direct ID Columns: calendar_resource_bookings and related tables expose direct IDs for performance-sensitive joins

Common Mistakes to Avoid

Missing Schema Prefix
- ❌ FROM calendar_events
- ✅ FROM planning_center.calendar_events
Adding Redundant RLS Filters
- ❌ WHERE tenant_organization_id = 1 AND system_status = 'active'
- ✅ Trust RLS to handle this automatically
Joining Without Schema
- ❌ JOIN calendar_resource_bookings rb ON ...
- ✅ JOIN planning_center.calendar_resource_bookings rb ON ...
Misreporting Fees
- ❌ SELECT resource_fee_cents as resource_fee
- ✅ SELECT resource_fee_cents / 100.0 as resource_fee

Performance Considerations

Indexes: All tables have optimized indexes on:
- Primary keys and entity IDs
- Join columns and foreign keys
- Date columns for time-based queries
Query Optimization:
- Always use the planning_center. schema prefix
- RLS handles tenant and status filtering automatically
- Filter by approval or conflict flags when relevant
- Consider CTEs for complex hierarchical queries
- Use direct ID columns when available instead of relationship tables

Data Types and Conventions

Approval Statuses

A - Approved
P - Pending approval
R - Rejected
NULL - No approval required

Resource Types (kind)

Room - Physical spaces
Equipment - Movable items
Resource - Other bookable items

All-Day Events

all_day_event = true indicates full-day events
Check date portions of starts_at and ends_at
May span multiple days

Recurrence Patterns

Stored in iCal RRULE format in recurrence field
Human-readable in recurrence_description
Each occurrence is a separate event_instance
