Need help trying to EagerLoad some data in EntityFramework
I'm trying to do some eager loading on an EF Entity.
so, if the entity is called Orders
.. then I guess i would do the following...
_someContext.Orders.Include("Whatever") ....
But the problem is, I have a method like the following ...
public IQueryable<Order> Find(Expression<Func<Order, bool>> predicate)
{
return CurrentContext.Orders.Where(predicate);
}

which works great .. but can i leverage the Expression
predicate to include the Include("whatever")
in there, instead of having to add another method parameter?
I don't think so. Since the predicate and ObjectQuery.Where Method in genral has nothing to do with eager loading by Include. You can create a extension method though, but that does not save you from having yet another parameter for specifying the include:
public IQueryable<Order> Find(Expression<Func> predicate, string include) {
return CurrentContext.Orders.Where(predicate, include);
}
public static ObjectQuery<T> Where<T>(this ObjectQuery<T> entity, Expression<Func<T, bool>> predicate, string include) {
return (ObjectQuery<T>)entity.Include(include).Where<T>(predicate);
}
