Intro
In this we will continue with the last one and add Ef core to our Minimal ABP module.
This is a continuation of Part 1
Create the project
dotnet new web -n MinimalEFWithAbp
Navigate to the MinimalEFWithAbp
folder and add the required packages.
Add required packages
To add the required packages use the dotnet add package
command.
dotnet add package Volo.Abp.Autofac
dotnet add package Volo.Abp.AspNetCore.Mvc
dotnet add package Volo.Abp.EntityFrameworkCore.Sqlite
dotnet add package Microsoft.EntityFrameworkCore.Design
Create Entity
We will create a simple Book
Entity.
public class Book : AuditedAggregateRoot<Guid>
{
public Book(Guid id, string name)
{
this.Id = id;
this.Name = name;
}
public string Name { get; set; }
}
Create DB Context
public class MyDbContext : AbpDbContext<MyDbContext>
{
public DbSet<Book> Books => Set<Book>();
public MyDbContext(DbContextOptions<MyDbContext> options)
: base(options)
{
}
protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
{
base.OnConfiguring(optionsBuilder);
optionsBuilder.UseSqlite();
}
protected override void OnModelCreating(ModelBuilder builder)
{
base.OnModelCreating(builder);
builder.Entity<Book>(b =>
{
b.ToTable("Books");
b.ConfigureByConvention();
b.HasData(new Book(Guid.NewGuid(),"My Book"));
});
}
}
This db context will configure the entity and also seed the database with one data.
Create the minimal module
[DependsOn(
typeof(AbpAspNetCoreMvcModule),
typeof(AbpAutofacModule),
typeof(AbpEntityFrameworkCoreSqliteModule)
)]
public class MinimalModule : AbpModule
{
public override void ConfigureServices(ServiceConfigurationContext context)
{
context.Services.AddAbpDbContext<MyDbContext>(options =>
{
options.AddDefaultRepositories(includeAllEntities: true);
});
Configure<AbpDbContextOptions>(options =>
{
options.UseSqlite();
});
}
}
Create the minimal api
var builder = WebApplication.CreateBuilder(args);
builder.Host.AddAppSettingsSecretsJson()
.UseAutofac();
builder.Services.ReplaceConfiguration(builder.Configuration);
builder.Services.AddApplication<MinimalModule>();
var app = builder.Build();
app.MapGet("/book", async ([FromServices] IRepository<Book, Guid> repository) =>
{
return await repository.GetListAsync();
});
app.InitializeApplication();
app.Run();
We have one GET
request which will return the data from the db.
Add connection string
update the appsettings.json
with the ConnectionStrings
"ConnectionStrings": {
"Default": "Filename=./db.sqlite"
}
Create migration
Now our app is ready lets create migrations for the DBcontext.
dotnet ef migrations add init
Apply migrations to DB
dotnet ef database update
Run the App
dotnet run
View the Book
Once the application is launched navigate to /book
you will see the seeded book as a json response.
