Exclude Property from Automapping?

[Chris Cyvas]

Is there a way to exclude certain properties from being mapped when
using the AutoMapping functionality? For instance, I have Price and
Quantity in my partial class, but I wanted to be able to add another
partial class that has an ExtendedPrice (Price * Quantity) property in
it that will not be persisted - so I want to exclude that from the
mapping. Any help is appreciated.

Hi Chris, I faced the same problem and I noticed I would always have
to write the IgnoreProperty using the OverrideAll for each property I
would like to ignore.
So, I created a class inheriting from Attribute like this:

public class NotPersisted : Attribute
{
}

And put the attibute over the non persisted Property:

public class Product
{
[NotPersisted]
public virtual double PriceQuery {get; set;}
}

Now, to ignore all properties in your code which receive the Attribute
NotPersisted:

model.OverrideAll(p =>
{
p.IgnoreProperties(x =>
x.GetCustomAttributes(typeof(IgnoreProperty), false).Length > 0);
});

I am new using the Fluent Auto Map, but it really works for me! :-)

Cheers,
André

Hi Andre,

Thanks for this! I noticed that in the documentation and figured I'd
have to go that route, but having a solid example will be a big help -
Thanks!
