Question

I have created two DbContexts, one is for application configuration, the second is for logging.

The reason being, I want to set a maximum size on the logging db so it doesn’t use up all free disk space and prevent other databases from working.

In my global.asax.cs file, I have the following:

        protected void Application_Start()
    {

        AreaRegistration.RegisterAllAreas();

        RegisterGlobalFilters(GlobalFilters.Filters);
        RegisterRoutes(RouteTable.Routes);

        Database.SetInitializer<AdminContext>(new AdminInitialiser());
        Database.SetInitializer<LoggingContext>(new LoggingInitialiser());
    }

The InitializeDatabase method in LoggingInitialiser is not being called. Is this because only one initializer can be set? Is there any way to have initializers for two DbContexts?

Answer 1

Set the initializer in the DbContext constructor instead.

public class AdminContext : DbContext
{
    public AdminContext()
    {
        Database.SetInitializer(new AdminInitialiser());
    }
}

public class LoggingContext : DbContext
{
    public LoggingContext()
    {
        Database.SetInitializer(new LoggingInitialiser());
    }
}
