I am trying to set up an additional EF Core provider for Postgres and I am having an issue overriding the naming strategy used by OrmLite. I have the following in my ConfigureDb which will correctly INSERT records into the quay.ApiKey
table, but will not SELECT correctly:
typeof(ApiKeysFeature.ApiKey)
.AddAttributes(new SchemaAttribute("quay"));
typeof(CrudEvent)
.AddAttributes(new SchemaAttribute("quay"));
typeof(Migration)
.AddAttributes(new SchemaAttribute("quay"));
typeof(Migration1000.Booking)
.AddAttributes(new SchemaAttribute("quay"));
typeof(Migration1000.Coupon)
.AddAttributes(new SchemaAttribute("quay"));
// Reset the naming strategy to get the correct TableName casing
PostgreSqlDialect.Provider.NamingStrategy = new PostgresNamingStrategy();
services.AddSingleton<IDbConnectionFactory>(new OrmLiteConnectionFactory(
connectionString, PostgreSqlDialect.Provider));
services.AddDbContext<ApplicationDbContextPostgres>(options =>
options.UseNpgsql(connectionString, b =>
{
b.MigrationsAssembly("Quay.Hive.Core.Data.Postgres");
b.MigrationsHistoryTable("MigrationCore", "quay");
}));
The naming strategy is as below (a bit redundant, but I wanted to check the values):
public class PostgresNamingStrategy : OrmLiteNamingStrategyBase
{
public override string GetTableName(string name)
{
Console.WriteLine("table name: " + name);
return name;
}
public override string GetColumnName(string name)
{
Console.WriteLine("column name: " + name);
return name;
}
public override string GetSchemaName(string name)
{
Console.WriteLine("schema name: " + name);
return name;
}
}
The error I am getting is below:
fail: ServiceStack.ServiceStackHost[0]
42703: column "id" does not exist
POSITION: 269

Is there somewhere else I should be assigning the PostgresNamingStrategy
to ensure that it is used for the var q = db.From<ApiKeysFeature.ApiKey>()
?
Hi @bradbrowne ,
I had a go at reproducing your setup and can get the same error you are seeing, however I noticed that if I didn’t use the custom PostgresNamingStrategy
applied to PostgreSqlDialect.Provider.NamingStrategy
everything works as expected. Are you able to remove this to confirm you are seeing the same thing, so I that I know the reproduction I have is behaving the same way.
I updated the custom PostgresNamingStrategy
the following, inheriting from the default one and calling the base, logging both names, showing the difference which I think might be causing the problem.
public class PostgresNamingStrategy : PostgreSqlNamingStrategy
{
public override string GetTableName(string name)
{
Console.WriteLine("table name: " + name);
var res = base.GetTableName(name);
Console.WriteLine($"resolved table name: {res}");
return res;
}
public override string GetColumnName(string name)
{
Console.WriteLine("column name: " + name);
var res = base.GetColumnName(name);
Console.WriteLine($"resolved column name: {res}");
return res;
}
public override string GetSchemaName(string name)
{
Console.WriteLine("schema name: " + name);
var res = base.GetSchemaName(name);
Console.WriteLine($"resolved schema name: {res}");
return res;
}
}
Some of the output below when loading the Admin UI API keys page:
table name: ApiKey
resolved table name: api_key
column name: Name
resolved column name: name
schema name: quay
resolved schema name: quay
table name: ApiKey
resolved table name: api_key
column name: UserId
resolved column name: user_id
How are you initializing the ApiKeysFeature schema?
Try changing that and let me know if you are still seeing an error.
Ahh apologies, I missed this the first time. I can indeed reproduce, and think have found the root cause but still investigating.

I am initializing the ApiKeysFeature schema using the npm run migrate
task that ships by default and I am configuring it as follows:
public class ConfigureApiKeys : IHostingStartup
{
public void Configure(IWebHostBuilder builder) => builder
.ConfigureServices(services => {
services.AddPlugin(new ApiKeysFeature());
})
.ConfigureAppHost(appHost => {
using var db = appHost.Resolve<IDbConnectionFactory>().Open();
var feature = appHost.GetPlugin<ApiKeysFeature>();
feature.InitSchema(db);
});
}
Just to clarify – the table name is created successfully as quay.ApiKey
(once I override the PostgreSqlDialect.Provider.NamingStrategy
) and I would like to keep that.
It is just that OrmLite does not seem to reflect the PostgreSqlDialect.Provider.NamingStrategy
when querying the columns of the quay.ApiKey
table, i.e., it is using id
when it should be Id
.
Yeah, it looks like it was a problem with the Admin UI combined with the query service. The OrderBy
option from the Admin UI is always in a specific case since the Admin UI needs consistent casing. This has been updated to handle this in this commit and should be available in our pre-release feeds as the latest v8.3.1. If you were already using these feeds, you will need to locally clear your NuGet cache to pull the latest.

Thank you – I have referenced the 8.3.1 Nuget packages and can confirm that the issue is resolved!
I really appreciate your help ![:smiley: :smiley:](https://forums.servicestack.net/images/emoji/twitter/smiley.png?v=12)
