❔ Access a DB property from a not mapped property
I have 2 models, A and B.
A includes a property X that I want to store in property Y in B.
Property X is stored in a DB, property Y is not mapped.
How can I achieve this? Simply doing
get => A.X does not seem to work in property Y11 Replies

Just realized I totally messed up the question.
Class A has this property
[ForeignKey("ArticleID")]
public ArticleModel Foo {
get => Get(ref article);
set => Set(value, ref article);
}
private ArticleModel article = null;
Which references this property in class B:
[ForeignKey("KindID")]
public KindModel Bar {
get => Get(ref kind);
set => Set(value, ref kind);
}
private KindModel kind = null;
Now in class A I want another property of type KindModel that stores the value of Bar, which is the same type.Unknown User•12mo ago

Yeah so that is the issue I think, those are self written methods for lazy loading:
protected virtual T Get<T>(ref T backingField, [CallerMemberName] string name = null) where T : LazyLoaderModel {TeBeCo
what library are you using to access the data

EF Core is used to access sqlite db, we use lazy loading because what our data models is only usefull in its entirety

If you use all the data... load all the data, eagerly
Why have 7142 round trips to the database when 1 trip will do?
Or use graphql + EF core, if your system cannot have a stable set of required data
