Hello. I'm in the process of learning Umbraco, and i've run into an issue that i can't figure out how to handle correctly.

What i'm a trying to do

• Find and ancestor of a specific type
• Use the ancestor to filter a query to find items that contains a specifik value.

My query

var uddannelse = Model.Ancestors().OfTypes("uddannelse").FirstOrDefault();
var medarbejdere = Umbraco.Content(Guid.Parse("e7ab5690-bb1b-48e7-900e-521a22e2c2d2"))
.ChildrenOfType("medarbejder")
.Where(x => x.IsVisible()).Where((x => x.Value<bool>("isVejleder") && x.Value<IPublishedContent>("uddannelse").Id == uddannelse.Id));

My current solution where i just wrap everything in an if(), this works but seems clumsy.

@if(Model.Ancestors().OfTypes("uddannelse").FirstOrDefault() != null){

var uddannelse = Model.Ancestors().OfTypes("uddannelse").FirstOrDefault();
var medarbejdere = Umbraco.Content(Guid.Parse("e7ab5690-bb1b-48e7-900e-521a22e2c2d2"))
.ChildrenOfType("medarbejder")
.Where(x => x.IsVisible()).Where((x => x.Value<bool>("isVejleder") && x.Value<IPublishedContent>("uddannelse").Id == uddannelse.Id));


@if(medarbejdere.Any()){
    //do this
}
}else{
    //do this
}

What would be the correct way to do this, and is that a general way to handle possible 'Null' when querying.
