🛠️ Issue

• Closes [FEAT]: Implement Orders Module (GraphQL API) #242

📖 Description

This pull request implements a full-featured GraphQL Order module using NestJS and Prisma. It includes all key CRUD operations and a robust order status update flow using enum-based validation.

• ✅ Created Order entity with GraphQL schema and Prisma model
• ✅ Implemented CreateOrderInput, UpdateOrderStatusInput, and enum OrderStatus
• ✅ Added query resolvers: getOrdersByBuyer, getOrdersBySeller, getOrder
• ✅ Added mutation resolvers: createOrder, updateOrderStatus
• ✅ Integrated GraphQL enum registration for OrderStatus
• ✅ Fully tested mutations and queries via Postman
• ✅ Implemented error handling and enum compatibility fixes

🧪 Testing Summary

All GraphQL queries and mutations were tested using Postman with variable-based requests, ensuring type safety and correct enum resolution in the schema.

To keep consistency with the rest of the Prisma schema, the Order model should follow the same style:

• Use camelCase field names in Prisma (productId, buyerAddress, etc.).
• Use @map() to map to snake_case database columns (product_id, buyer_address, etc.).

Example:

model Order {
  id            String   @id @default(uuid())
  productId     String   @map("product_id")
  buyerAddress  String   @map("buyer_address")
  sellerAddress String   @map("seller_address")
  escrowId      String   @map("escrow_id")
  status        OrderStatus @default(PENDING)
  createdAt     DateTime @default(now()) @map("created_at")
  updatedAt     DateTime @updatedAt @map("updated_at")
  messages Message[]

  product        Product     @relation(fields: [productId], references: [id])

  @@map("orders")
}

This will match the style used in other models like Product and User.

Update the entity, service and tests to match the new field names.
