I need to bind with Ninject to database and inject them to same repository in same time

Question

Here some parts of my code class NinjectWebCommon place where I need bind dada contexts. It is just piece of the code, not complete classes.

private static void RegisterServices(IKernel kernel)
        {
            kernel.BindSharpRepository();
            RepositoryDependencyResolver.SetDependencyResolver(new NinjectDependencyResolver(kernel));

            kernel.Bind<DbContext>().To<EntitiesDbOne>().InRequestScope();

        //kernel.Bind<DbContext>().To<EntitiesDbTwo>().InRequestScope();
    }  

Category Repository class where i need to have two databases in same time

public class CategoryRepository : ConfigurationBasedRepository<CategoryData, int>, ICategoryRepository
    {
    private readonly EntitiesDbOne _ctxOne;
        private readonly EntitiesDbTwo _ctxTwo;

    public CategoryRepository(EntitiesDbOne ctxOne, EntitiesDbTwo ctxTwo)
        {
            _ctxOne= ctxOne;
            _ctxTwo= ctxTwo;
        }

    public CategoryData GetById(int Id)
        {
             //dummy data, just for usage two different dcContexts
             var category = _ctxOne.Categories.Include((string) (x => x.MetaTags)).FirstOrDefault(x => x.Id == Id);
             var categoryName = _ctxTwo.category.FirstOrDefault(x => x.Id == category.Id);

            return category;
        }

In my project I use SharpRepository(ConfigurationBasedRepository) and I use UnitOfWork. I think I can skip UnitOfWork because EntityFramework is doing all this (UnitOfWork patterns) job. Booth of databases is EntityFramework one is CodeFirst approach other (DbTwo) modelFirst

public class EntitiesDbOne : DbContext
    {
        public DbSet<CategoryData> Categories { get; set; }
}

public partial class EntitiesDbTwo: DbContext
    {
        public EntitiesDbTwo()
            : base("name=EntitiesDbTwo")
        {
        }

        public DbSet<attributenames> attributenames { get; set; }
        public DbSet<category> category { get; set; }
}

Please give me some links to examples I can use, I do not think I can manage this with simple explanation. Before I wrote this question, I had search for the answer here on the Multiple DbContexts in N-Tier Application

EF and repository pattern - ending up with multiple DbContexts in one controller - any issues (performance, data integrity)?

This question by the name is complete in my situation but the code for me, is far different. Multiple dbcontexts with Repository, UnitOfWork and Ninject

This one is multiple databases but use one per request, and I need two databases in the same request. http://blog.staticvoid.co.nz/2012/1/9/multiple_repository_data_contexts_with_my_repository_pattern site and other place.

I read about 20 suggestions, there are two close to my situation but probably not enough.

Answer 1

just as a basis for discussion:

What if you use:

kernel.Bind<EntitiesDbOne>().ToSelf().InRequestScope();
kernel.Bind<EntitiesDbTwo>().ToSelf().InRequestScope();

and use it like

public class CategoryRepository : ConfigurationBasedRepository<CategoryData, int>,    ICategoryRepository
{

    public CategoryRepository(EntitiesDbOne ctxOne, EntitiesDbTwo ctxTwo)
    {
    }
}

what's the issue then?
