⚡ Energy Service API

A sample .NET 9 Web API for managing customers, products, tariffs, and orders for energy-based services (electricity, gas, etc.).

---

🧩 Overview

This project demonstrates a typical business structure for energy contract management:

Customer
 └── Order
      └── OrderDetail
           ├── Product
           └── Tariff → Unit

Each tariff can have multiple time-based prices.

🗂️ Project Structure

Folder	Description
Models/	Entity classes (Customer, Product, Tariff, Unit, Order, OrderItem)
Data/	AppDbContext and SeedData for initialization
Controllers/	API endpoints (to be extended)
Migrations/	EF Core migrations

---

⚙️ Configuration

Edit your appsettings.json to set the connection string:

"ConnectionStrings": {
  "DefaultConnection": "xxx"
}

---

🌱 Seeding Data

On first startup, the app automatically seeds demo data.

To reseed the database (for development only), use:

SeedData.Initialize(db, force: true);

This clears all tables and re-inserts demo data.

---

🧱 Migrations

Generate a new migration whenever you modify the model classes:

dotnet ef migrations add AddNewFieldName
dotnet ef database update
