I have this classes (after removing redundant information from them):
public class Category : BaseEntity
{
public virtual Category ContainingCategory { get; set; }
public virtual IList<CategoryProperty> Properties { get; set; }
}
public class CategoryProperty : BaseEntity
{
public virtual string Name { get; set; }
public virtual IList<CategoryPropertyValue> Values { get; set; }
}
public class CategoryPropertyValue : BaseEntity
{
public virtual string Name { get; set; }
}
public class CategoryPropertyValueCollection : BaseEntity
{
public virtual IList<CategoryPropertyValue> Values { get; set; }
}
public class Product : BaseEntity
{
public virtual string Name { get; set; }
public virtual Category ContainingCategory { get; set; }
public virtual IDictionary<CategoryProperty, CategoryPropertyValueCollection> Properties { get; set; }
}
And those are my mapping (after removing redundant information again):
public class CategoryMap : BaseMap<Category>
{
public CategoryMap()
{
Map(x => x.Name);
HasMany(x => x.Properties);
}
}
public class CategoryPropertyMap : BaseMap<CategoryProperty>
{
public CategoryPropertyMap()
{
Map(x => x.Name);
HasMany(x => x.Values);
}
}
public class CategoryPropertyValueMap : BaseMap<CategoryPropertyValue>
{
public CategoryPropertyValueMap()
{
Map(x => x.Name);
}
}
public class CategoryPropertyValueCollectionMap : BaseMap<CategoryPropertyValueCollection>
{
public CategoryPropertyValueCollectionMap()
{
HasMany(x => x.Values).Cascade.None();
}
}
public class ProductMap : BaseMap<Product>
{
public ProductMap()
{
Map(x => x.Name);
HasMany(x => x.Properties).AsEntityMap();
}
}
Something is wrong with my mappings, it's easy to see what I'm trying to accomplish (ebay will be a good example of that logic - products from categories that has properties that varies and possible values to filter by). This is that tables I'm getting (which aren't good):
create table Categories (
Id INT IDENTITY NOT NULL,
Name NVARCHAR(255) null,
ContainingCategoryId INT null,
primary key (Id)
)
create table CategoryProperties (
Id INT IDENTITY NOT NULL,
Name NVARCHAR(255) null,
CategoryId INT null,
primary key (Id)
)
create table CategoryPropertyValueCollections (
Id INT IDENTITY NOT NULL,
ProductId INT null,
CategoryProperty_id INT null,
primary key (Id)
)
create table CategoryPropertyValues (
Id INT IDENTITY NOT NULL,
Name NVARCHAR(255) null,
CategoryPropertyId INT null,
CategoryPropertyValueCollectionId INT null,
OrderItemId INT null,
CategoryProperty_id INT null,
primary key (Id)
)
Why does 'CategoryPropertyValues' is created with a 'CategoryPropertyValueCollectionId' column? What am I doing wrong in the mapping?
Found out my problem was the usage of HasMany instead of HasManyToMany.
