## Entity Framework Core PostgreSQL Integration
|
||
|
|
|
||
|
|
> See [Entity Framework Core Integration document](../Entity-Framework-Core.md) for the basics of the EF Core integration.
|
||
|
|
|
||
|
|
### EntityFrameworkCore Project Update
|
||
|
|
|
||
|
|
- In `Acme.BookStore.EntityFrameworkCore` project replace package `Volo.Abp.EntityFrameworkCore.SqlServer` with `Volo.Abp.EntityFrameworkCore.PostgreSql`
|
||
|
|
- Update to use PostgreSQL in `BookStoreEntityFrameworkCoreModule`. Example:
|
||
|
|
|
||
|
|
````C#
|
||
|
|
[DependsOn(
|
||
|
|
//code omitted for brevity
|
||
|
|
|
||
|
|
/* This was updated from AbpEntityFrameworkCoreSqlServerModule */
|
||
|
|
typeof(AbpEntityFrameworkCorePostgreSqlModule),
|
||
|
|
/* This was updated from AbpEntityFrameworkCoreSqlServerModule */
|
||
|
|
|
||
|
|
//code omitted for brevity
|
||
|
|
)]
|
||
|
|
public class Acme.BookStore.EntityFrameworkCoreModule : AbpModule
|
||
|
|
{
|
||
|
|
public override void ConfigureServices(ServiceConfigurationContext context)
|
||
|
|
{
|
||
|
|
context.Services.AddAbpDbContext<BookStoreDbContext>(options =>
|
||
|
|
{
|
||
|
|
options.AddDefaultRepositories(includeAllEntities: true);
|
||
|
|
});
|
||
|
|
|
||
|
|
Configure<AbpDbContextOptions>(options =>
|
||
|
|
{
|
||
|
|
/* This was updated */
|
||
|
|
options.UsePostgreSql();
|
||
|
|
/* This was updated */
|
||
|
|
});
|
||
|
|
}
|
||
|
|
}
|
||
|
|
````
|
||
|
|
|
||
|
|
### EntityFrameworkCore.DbMigrations Project Update
|
||
|
|
- **Do** update to use PostgreSQL in `BookStoreMigrationsDbContextModelSnapshot.cs`
|
||
|
|
|
||
|
|
import `Npgsql.EntityFrameworkCore.PostgreSQL.Metadata` by adding
|
||
|
|
|
||
|
|
````C#
|
||
|
|
using Npgsql.EntityFrameworkCore.PostgreSQL.Metadata;
|
||
|
|
````
|
||
|
|
|
||
|
|
replace all references
|
||
|
|
````
|
||
|
|
.HasAnnotation("SqlServer:ValueGenerationStrategy", SqlServerValueGenerationStrategy.IdentityColumn);
|
||
|
|
````
|
||
|
|
|
||
|
|
to
|
||
|
|
|
||
|
|
````C#
|
||
|
|
.HasAnnotation("Npgsql:ValueGenerationStrategy", NpgsqlValueGenerationStrategy.SerialColumn);
|
||
|
|
````
|
||
|
|
|
||
|
|

|
||
|
|
> Update the PostgreSQL connection string in all `appsettings.json` files
