最後補充monogodb data seeding，可以不用再額外裝套件

操作

1. 寫seed

public class MongoDbSeeder
{
    private readonly AppMongoDbContext _context;

    public MongoDbSeeder(AppMongoDbContext dbContext)
    {
        _context = dbContext;
    }

    public async Task SeedAsync()
    {
        bool hasData = await _context.Tags.Find(_ => true).AnyAsync();

        if (!hasData)
        {
            var seedTags = new List<Tag>
            {
                new Tag { Name = "Reading insights" },
                new Tag { Name = "Programming" },
                new Tag { Name = "Mindfulness" },
            };

            await _context.Tags.InsertManyAsync(seedTags);
        }
    }
}

2. program.cs加入

builder.Services.AddTransient<MongoDbSeeder>();

using (var scope = app.Services.CreateScope())
{
    var seeder = scope.ServiceProvider.GetRequiredService<MongoDbSeeder>();
    await seeder.SeedAsync();
}

作者的哈拉

雖然沒有到棄賽，但也是蠻偏離原本預想的了...
希望下次參加可以先把整體大綱整理好，而不是每天都在趕鴨子上架
