How to save self tracking entities in entity framework?

Question

This is my database structure I have four tables. Table LocalArea and Lanungaue have master data and which refered by the tables Address and AddressTranslated

Now I want to add rows in Address and AddressTranslated table I used following code store Address table row

Address.localarea = new localarea() { LocalAreaID = 1 };

        using (var context = new en_Entities())
        {

            context.Address.Attach(Address);
            context.ObjectStateManager.ChangeObjectState(Address.LocalArea, EntityState.Unchanged);
            context.ObjectStateManager.ChangeObjectState(Address, EntityState.Added);

            context.SaveChanges();
        }

The code working fine and adds row in Address table.

How do i add row in AddressTranslated ?? what changes/line of code do i need to add data in AddressTranslate table.

Answer 1

My AddressTranslated table was not having any primary key column thats why couldnt add row to childtable.

After adding a primary key column all records got saved to DB.
