GodelTech.Database.EntityFrameworkCore

Description

GodelTech.Database.EntityFrameworkCore is a .NET library designed to work with databases, apply migrations, and manage data using Entity Framework Core. It simplifies the process of creating console applications with database migrations and data operations.

Overview

Using this library you can create console app with database migrations and data.

DatabaseService.cs

public class DatabaseService : DatabaseServiceBase
{
    public DatabaseService(
        BaseContext baseContext,
        WeatherContext weatherContext,
        IHostEnvironment hostEnvironment,
        ILogger<DatabaseService> logger)
        : base(logger, baseContext, weatherContext)
    {
        RegisterDataService(
            new DataService<WeatherEntity, Guid>(
                new ConfigurationBuilder(),
                hostEnvironment,
                @"Data\Weather",
                weatherContext,
                false,
                x => x.Id,
                logger
            )
        );
    }
}

Worker.cs

public class Worker : BackgroundService
{
    private readonly IServiceProvider _serviceProvider;
    private readonly ILogger<Worker> _logger;

    public Worker(IServiceProvider serviceProvider, ILogger<Worker> logger)
    {
        _serviceProvider = serviceProvider;
        _logger = logger;
    }

    private static readonly Action<ILogger, Exception> LogExecuteAsyncApplyDatabaseMigrationsInformation =
        LoggerMessage.Define(
            LogLevel.Information,
            new EventId(0, nameof(ExecuteAsync)),
            "Apply database migrations"
        );

    private static readonly Action<ILogger, Exception> LogExecuteAsyncApplyDatabaseDataInformation =
        LoggerMessage.Define(
            LogLevel.Information,
            new EventId(0, nameof(ExecuteAsync)),
            "Apply database data"
        );

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        using var scope = _serviceProvider.CreateScope();
        var databaseService = scope.ServiceProvider.GetRequiredService<DatabaseService>();

        LogExecuteAsyncApplyDatabaseMigrationsInformation(_logger, null);
        await databaseService.ApplyMigrationsAsync();

        LogExecuteAsyncApplyDatabaseDataInformation(_logger, null);
        await databaseService.ApplyDataAsync();
    }
}
