How do I delete a record?

Question

I'm trying to delete a database record using ASP.NET MVC, Fluent, and NHibernate. See the code below for examples of how I'm trying to accomplish this. I am able to Get, Update, and Insert records but Delete is not working. When the Delete() method gets called in the controller (top one) it throws an Exception (System.Data.SqlClient.SqlException: Invalid object name 'Styles'.).

I would like to avoid any sort of meta-SQL query because I don't want to hard code the table name into the controller if I don't have to.

Controller snippet:

// POST: /Brand/Delete/5
// Here is the handler in the controller
[HttpPost]
public ActionResult Delete(int id, FormCollection collection)
{
    try
    {
        IRepository<Brand> repo = new BrandRepository();
        repo.Delete(id);

        return RedirectToAction("Index");
    }
    catch
    {
        throw;
    }
}

Repository snippet:

//Here is the repository
//The insert/update/get/etc all work fine
void IRepository<Brand>.Delete(int id)
{
    using (ISession session = NHibernateHelper.OpenSession())
    {
        using (ITransaction transaction = session.BeginTransaction())
        {
            IRepository<Brand> repo = new BrandRepository();

            session.Delete(repo.GetById(id));
            transaction.Commit();
        }
    }
}

Mapping snippet:

//And here is the mapping for a Brand
public class BrandMap : ClassMap<Brand>
{
    public BrandMap()
    {
        Table("Brands");
        Id(x => x.Id).GeneratedBy.Identity();
        Map(x => x.Name);
        HasMany(x => x.Styles)
            .Inverse()
            .Cascade.All();
    }
}

Answer 1

It looks like the mapping of the Styles property is incorrect. Are you using a correct table name? From the exception it seems that there's no such table Styles.
