C# – Fluent NHibernate: How to map an entire class as ReadOnly

cfluent-nhibernatenhibernate

I have a few classes that read from very delicate tables, which is why I want them to be used by NHibernate as "ReadOnly". Establishing .ReadOnly() on each field map is really sloppy, and I'm not sure I trust it. How do I setup a class to be entirely readonly, as I can easily do with traditional XML mappings?

Edit: The answer does work. I expected it to throw an exception if I tried to save over a ReadOnly() object, but it just silently does so.

Thanks.

With Fluent NHibernate, it's as simple as:

class EntityMap : ClassMap<Entity>
{
    public EntityMap()
    {
        ReadOnly();

        // Mappings
    }
}

How to map an enum as an int value with fluent NHibernate

The way to define this convention changed sometimes ago, it's now :

public class EnumConvention : IUserTypeConvention
{
    public void Accept(IAcceptanceCriteria<IPropertyInspector> criteria)
    {
        criteria.Expect(x => x.Property.PropertyType.IsEnum);
    }

    public void Apply(IPropertyInstance target)
    {
        target.CustomType(target.Property.PropertyType);
    }
}

C# – Fluent NHibernate Inheritance Issue

figured it out

i had to change my HasMany mapping to include the DataItem type so that it knew to pull the field parentId from the DataItem table instead of my email table (where the field doesn't exist)

HasMany<DataItem>(user => user.Emails).KeyColumn("parentid").Cascade.All();

then in my User class change the method AddEmail to

public virtual void AddEmail(Email email)
{
    email.Parent = this;  //forgot to set it's parent..
    Emails.Add(email);
}

awesome tool.. very powerful!
