Common Field Patterns

Convention Reference

Every convention-scoped entity needs:

conventionId: text("convention_id")
  .notNull()
  .references(() => conventions.id, { onDelete: "cascade" }),

Application Workflow Fields

status: applicationStatusEnum("status").default("draft").notNull(),
submittedAt: timestamp("submitted_at"),
reviewedAt: timestamp("reviewed_at"),
reviewedBy: text("reviewed_by").references(() => users.id),
reviewNotes: text("review_notes"),

Payment Integration

stripePaymentIntentId: text("stripe_payment_intent_id"),
stripeCustomerId: text("stripe_customer_id"),
paymentStatus: paymentStatusEnum("payment_status").default("pending"),
paidAt: timestamp("paid_at"),
amountPaid: decimal("amount_paid", { precision: 10, scale: 2 }),

Contact Fields

contactName: text("contact_name").notNull(),
contactEmail: text("contact_email").notNull(),
contactPhone: text("contact_phone"),

Pricing Logic

Badge Pricing

• Early bird discount before cutoff date
• Child badges free under age 6
• Group discounts for 10+ badges
• Comped badges for sponsors/volunteers

Vendor Pricing

• Base price by booth type
• Corner premium (+25%)
• Electricity add-on
• Multi-day discount

Sponsor Tiers

const SPONSOR_TIERS = {
  bronze: { price: 250, passCount: 2, tableCount: 0 },
  silver: { price: 500, passCount: 4, tableCount: 1 },
  gold: { price: 1000, passCount: 6, tableCount: 2 },
  platinum: { price: 2000, passCount: 8, tableCount: 2, hotelNights: 2 },
  diamond: { price: 3000, passCount: 10, tableCount: 3, hotelNights: 3 },
};

UI Patterns

Dashboard Layout

/(dashboard)/
├── conventions/[id]/
│   ├── overview/          # Stats, recent activity
│   ├── attendees/         # Badge management
│   ├── vendors/           # Vendor applications
│   ├── sponsors/          # Sponsor management
│   ├── panels/            # Panel scheduling
│   ├── volunteers/        # Staff management
│   ├── schedule/          # Event calendar
│   └── settings/          # Convention config

Application Review Flow

// Always include:
// 1. Application details
// 2. Review history
// 3. Action buttons (Approve/Reject/Waitlist)
// 4. Notes field for reviewer comments

Status Badges

const statusColors = {
  draft: "gray",
  submitted: "blue",
  under_review: "yellow",
  approved: "green",
  rejected: "red",
  waitlisted: "orange",
};

Business Rules

Vendor Capacity

• Maximum vendors per convention (configurable)
• Waitlist when capacity reached
• Auto-promote from waitlist on cancellation

Panel Scheduling

• No speaker double-booking
• Room capacity validation
• Time slot conflict detection

Volunteer Shifts

• Minimum shift length: 2 hours
• Maximum hours per day: 8
• Required rest between shifts: 8 hours

Sponsor Benefits

• Benefits tied to tier, not individual
• Pro-rated benefits for late sponsors
• Rollover logic for unused benefits

Error Messages

Use domain-appropriate error messages:

// Good
throw new TRPCError({
  code: "BAD_REQUEST",
  message: "Cannot submit application: required fields missing",
});

// Bad
throw new TRPCError({
  code: "BAD_REQUEST", 
  message: "Validation failed",
});

Testing Patterns

// Test data factories
const createTestConvention = () => ({
  name: "Test Con 2025",
  startDate: new Date("2025-06-15"),
  endDate: new Date("2025-06-17"),
});

const createTestVendor = (conventionId: string) => ({
  conventionId,
  businessName: "Test Vendor",
  contactEmail: "test@vendor.com",
  boothType: "standard",
});
