Dynamic dynamic automatic formatting
1 answer
We have successfully used the following approach (with FluentNH 1.2.0.712):
public class SomeClass
{
public int Id { get; set; }
public IDictionary Properties { get; set; }
}
public class SomeClassMapping : ClassMap<SomeClass>
{
public SomeClassMapping()
{
Id(x => x.Id);
// Maps the MyEnum members to separate int columns.
DynamicComponent(x => x.Properties,
c =>
{
foreach (var name in Enum.GetNames(typeof(MyEnum)))
c.Map<int>(name);
});
}
}
Here we have mapped all members of some Enum to separate columns, where they are all of type int . I am currently working on a scenario where we use different types for dynamic columns that look like this:
// ExtendedProperties contains custom objects with Name and Type members
foreach (var property in ExtendedProperties)
{
var prop = property;
part.Map(prop.Name).CustomType(prop.Type);
}
It also works really well.
What else am I going to figure out how to use References
instead Map
to refer to other types that have their own mapping ...
UPDATE: Unfortunately, the recommendation case is more complicated, refer to this topic on Google Groups . Shortly speaking:
// This won't work
foreach (var property in ExtendedProperties)
{
var prop = property;
part.Reference(dict => dict[part.Name]);
}
// This works but is not very dynamic
foreach (var property in ExtendedProperties)
{
var prop = property;
part.Reference<PropertyType>(dict => dict["MyProperty"]);
}
That's all for now.
