    Get all products by custom property in array

    Hi all

     

    I'm trying to get all products in my catalog where the value of a custom property is in a predefined array.

     

     

    
    var eansstr = "4019238560824;4019238560825";
    var eans = eansstr.Split(';');
    var products = Product.All().Where(x => x.GetProperty("EAN").GetValue() == eans[0]);
    foreach (var p in products) {

    @p.Name
    
}

     

    But I get the error message System.NotSupportedException: System.Object GetValue()

     

    How to fix?

    Took some advice from another thread and changed it to this:

     

    Product.All().Where(x => x.ProductProperties.Any(y => y.ProductDefinitionField.Name == "EAN" && eans.Contains(y.Value)));

     

    Now it works :)

    Hi Søren

    The problem is that NHibernate can't translate "GetValue()" to SQL.

    The solution is quering from the productproperty entity like this:

    ProductProperty.All()
            .Where(pp => pp.ProductDefinitionField.Name == "EAN" && pp.Value == "ABC")
            .Select(pp => pp.Product);

    or like this

    Product.All().Where(p => p.ProductProperties.Any(pp => pp.ProductDefinitionField.Name == "EAN" && pp.Value == "abc"));

    (Not tested - hope it points you in the right direction)
