Automatically add entities to the DbContext Model

1. As normal, create your Entity class in the Domain layer

2. Add the Amos.Abp.EntityFrameworkCore Nuget package to your EntityFrameworkCore layer

3. Using AutoAddEntityToModelAttribute tag your DbContext interface

   [AutoAddEntityToModel(typeof(YourDomainModule))]
   public interface IYourDbContext : IEfCoreDbContext
   {
   }

4. Call the AutoAddEntityTypeToModel method in your DbContext class (Note: Call it before base.OnModelCreating)

   [ConnectionStringName(YourDbProperties.ConnectionStringName)]
   public class YourDbContext : AbpDbContext<YourDbContext>, IYourDbContext
   {
       public YourDbContext(DbContextOptions<YourDbContext> options): base(options)
       {
       }
   
       protected override void OnModelCreating(ModelBuilder builder)
       {
           builder.AutoAddEntityTypeToModel(this);//Note: Call it before base.OnModelCreating
           base.OnModelCreating(builder);
           builder.ConfigureYourModule();
       }
   }

5. Follow Volo abp modular best practices, configure the automatically add entities in your ModuleDbContextModelCreatingExtensions

   public static class YourModuleDbContextModelCreatingExtensions
   {
       public static void ConfigureYourModule(
           this ModelBuilder builder,
           Action<YourModuleModelBuilderConfigurationOptions> optionsAction = null)
       {
           Check.NotNull(builder, nameof(builder));
   
           var options = new YourModuleModelBuilderConfigurationOptions(
               YourDbProperties.DbTablePrefix,
               YourDbProperties.DbSchema
           );
   
           optionsAction?.Invoke(options);
   
           builder.ConfigureAutoAddEntityTypes<IYourDbContext>((entityType) => (b) =>
           {
               b.ToTable(options.TablePrefix + entityType.Name, options.Schema);
               b.ConfigureByConvention();
           });
   
           builder.ApplyConfigurationsFromAssembly(Assembly.GetExecutingAssembly());
       }
   }

   You are advised to configure the index, Key, etc., by implementing the EfCore IEntityTypeConfiguration interface, at your EntityFrameworkCore layer

   public class ProductConfiguration : IEntityTypeConfiguration<Product>
   {
       public void Configure(EntityTypeBuilder<Product> builder)
       {
           builder.HasIndex(h => h.Name).HasFilter("IsDeleted=0").IsUnique();
       }
   }

   Then by calling the builder.ApplyConfigurationsFromAssembly(Assembly.GetExecutingAssembly()) configuration entity, just like the example above

6. Register automatically add entities repository and DependsOn in your EntityFrameworkCoreModule, use AddAbpDbContextEx instead of AddAbpDbContext

   [DependsOn(typeof(YourDomainModule))]
   [DependsOn(typeof(AmosAbpEntityFrameworkCoreModule))]
   public class YourEntityFrameworkCoreModule : AbpModule
   {
       public override void ConfigureServices(ServiceConfigurationContext context)
       {
           context.Services.AddAbpDbContextEx<OrderManagementDbContext>(options =>{});
       }
   }

7. Finally, as normal, you can inject automatically add entity repository to use

   public class YourAppService : IYourAppService
   {
       private readonly Lazy<IRepository<XXEntity, long>> _xxRepositoryLazy;
   
       public YourAppService(Lazy<IRepository<XXEntity, long>> xxRepositoryLazy)
       {
           _xxRepositoryLazy = xxRepositoryLazy;
       }
   }

Temp Table

• What is an SQL Temp Table (https://www.databasestar.com/sql-temp-table/)
• At present, only SQL Server Temp Table is implemented. If you use other database provider, you can expand the database support by implementing ITempTableCreator, ITempTableBulkExecutor interfaces

1. Add the Amos.Abp.Domain Nuget package to your Domain layer
2. Create TempTable class in the Domain layer

   public class YourTempTable : ITempTable
   {
       public int Id { get; set; }
   }

3. Define a temp table repository interface in the Domain layer

   public interface IYourTempTableRepository : ITempTableRepository
   {
   }

4. Add the Amos.Abp.TempTable.SqlServer Nuget package to your EntityFrameworkCore layer
5. Using AutoAddTempTableToModelAttribute tag your DbContext interface

   [AutoAddTempTableToModel(typeof(YourDomainModule))]
   public interface IYourDbContext : IEfCoreDbContext
   {
   }

6. Call the AutoAddTempTableToModel method in your DbContext class (Note: Call it before base.OnModelCreating)

   [ConnectionStringName(YourDbProperties.ConnectionStringName)]
   public class YourDbContext : AbpDbContext<YourDbContext>, IYourDbContext
   {
       public YourDbContext(DbContextOptions<YourDbContext> options): base(options)
       {
       }
   
       protected override void OnModelCreating(ModelBuilder builder)
       {
           builder.AutoAddTempTableToModel(this);//Note: Call it before base.OnModelCreating
           base.OnModelCreating(builder);
       }
   }

7. Implement temp table repository in the EntityFrameworkCore layer

   public class YourTempTableRepository : EfCoreTempTableRepository<IYourDbContext>, IYourTempTableRepository, ITransientDependency
   {
       public YourTempTableRepository(IDbContextProvider<IYourDbContext> dbContextProvider) 
           : base(dbContextProvider)
       {
       }
   }

8. Add DependsOn to your EntityFrameworkCoreModule

   [DependsOn(typeof(AmosAbpTempTableSqlServerModule))]
   public class YourEntityFrameworkCoreModule : AbpModule
   {
   }

9. Finally, you can inject temp table repository to use

   public class YourAppService : IYourAppService
   {
       private readonly Lazy<IYourTempTableRepository> _yourTempTableRepositoryLazy;
       private readonly Lazy<IRepository<XXEntity, long>> _xxRepositoryLazy;
   
       public YourAppService(Lazy<IYourTempTableRepository> yourTempTableRepositoryLazy,Lazy<IRepository<XXEntity, long>> xxRepositoryLazy)
       {
           _yourTempTableRepositoryLazy = yourTempTableRepositoryLazy;
           _xxRepositoryLazy=xxRepositoryLazy;
       }
   
       public async Task TestAsync()
       {
           var tempDatas = new List<YourTempTable> { new YourTempTable { Id = 1 }, new YourTempTable { Id = 2 } };
           var tempQuery = await _yourTempTableRepositoryLazy.Value.InsertIntoTempTableAsync(tempDatas);
   
           var query = await _xxRepositoryLazy.Value.GetQueryableAsync();
           var tempWhereQuery = query.Where(w => tempQuery.Any(a => a.Id == w.Id));
           var tempWhereResult = await _xxRepositoryLazy.Value.AsyncExecuter.ToListAsync(tempWhereQuery);
       }
   }

Sql Script

• This feature is used to perform high-performance database operations using native sql
• Centralized management of sql scripts
• Easily supports multiple different database provider(MySql, SqlServer, Oracle, etc. please see the Volo.Abp.EntityFrameworkCore.EfCoreDatabaseProvider), Reduce the impact of different database provider sql syntax differences
• Based on EFCore, Dapper makes almost no disruptive adjustments to the original configuration

1. Add the Amos.Abp.Domain Nuget package to your Domain layer
2. Define a sql script repository interface in the Domain layer

   public interface IYourSqlScriptRepository : ISqlScriptRepository
   {
   }

3. Add the Amos.Abp.SqlScript Nuget package to your EntityFrameworkCore layer
4. Create sql script resource file in the EntityFrameworkCore layer (Similar to defining multilingual resource files, Please refer to the screenshot below)
   

   • Create a SqlScript folder, and define an sql script resource empty class in this folder

     public class YourSqlScriptResource
     {
     }

   • Create a folder with the same name as the sql script resource empty class (eg: create a folder name OrderManagement for OrderManagementSqlScriptResource)

   • Create sql script xml file for your database provider, and set it as an embedded resource

     <?xml version="1.0" encoding="utf-8" ?>
     <SqlScripts Namespace="OrderManagement" DatabaseProvider="SqlServer" >
         <Item Key="SelectProductById">select * from Order where Id=@Id</Item>
         <Item Key="SoftDeleteProductById">update Order set IsDelete=1 where Id=@Id</Item>
         <Item Key="SelectDynamicTableById">select * from {{table}} where Id=@Id</Item>
         <Item Key="TestMultiline">
             select * from Order where Id=@Id;
             select * from OrderItems
         </Item>
     </SqlScripts>

     Note: [Namespace] and [DatabaseProvider] are correctly filled in the xml

   • Configure SqlScriptOptions and add DependsOn in your EntityFrameworkCoreModule

     [DependsOn(typeof(AmosAbpSqlScriptModule))]
     public class YourEntityFrameworkCoreModule : AbpModule
     {
         public override void ConfigureServices(ServiceConfigurationContext context)
         {
             Configure<SqlScriptOptions>(options =>
             {
                 options.AddResource("YourDefinedSqlScriptNamespace", typeof(YourSqlScriptResource));
             });
         }
     }

     Note: [YourDefinedSqlScriptNamespace] is same as xml file [Namespace]

5. Implement sql script repository in the EntityFrameworkCore layer

   public class YourSqlScriptRepository : SqlScriptRepository<IYourDbContext>, IYourSqlScriptRepository, ITransientDependency
   {
       public YourSqlScriptRepository(IDbContextProvider<IProductManagementDbContext> dbContextProvider, ISqlScriptProvider sqlScriptProvider) 
           : base(dbContextProvider, sqlScriptProvider)
       {
       }
   }

6. Finally, you can inject temp table repository to use

   public class YourAppService : IYourAppService
   {
       private readonly Lazy<IYourSqlScriptRepository> _yourSqlScriptRepositoryLazy;
   
       public YourAppService(Lazy<IYourSqlScriptRepository> yourSqlScriptRepositoryLazy)
       {
           _yourSqlScriptRepositoryLazy = yourSqlScriptRepositoryLazy;
       }
   
       public async Task TestAsync()
       {
           var ds = await _yourSqlScriptRepositoryLazy.Value.QueryAsDataSetAsync("OrderManagement:TestMultiline", sqlParam: new { Id = 1 });
           var dt = await _yourSqlScriptRepositoryLazy.Value
           .QueryAsDataTableAsync("OrderManagement:SelectDynamicTableById",new { table= "Order" }, new { Id = 1 });        
       }
   }

   Note: sql scirpt depends on the database provider you set in DbContext (Get database provider : ((EfCoreDatabaseProvider)dbContext.Model["_Abp_DatabaseProvider"], if your DbContext setting uses SqlServer, sql scirpt in SqlServer.xml will be used, if your DbContext setting uses MySql, sql scirpt in MySql.xml will be used)
