Auditing EF8 Core Complex Properties

[NickNightingale]

I am a new user of Audit.EntityFramework.Core. I am auditing quite a simple database using AuditTypeNameMapper and mostly everything is working really well. I have a few complex properties (e.g. a struct with X and Y properties) and while I can see these in the EntityFrameworkEvent separated out into their generated column names (e.g. Element_X and Element_Y), they do not get copied automatically into the matching audit record. Is this a limitation of the column matching? If so is there a better way to handle this type of property?

I assume you're referring to an audit log entity where the column names of complex properties correspond directly to the audit entity properties.

[ComplexType]
class Element 
{ 
  public int X { get; set; } 
  public int Y { get; set; } 
}

// Entity to audit
class Foo
{
    [Key]
    public int Id { get; set; }
    public string Name { get; set; }
    public Element Element { get; set; }
}

// Audit entity with 'matching' properties
class FooAuditLog
{
    [Key]
    public int AuditId { get; set; }

    public string Name { get; set; }

    [Required]
    public Element Element { get; set; } // <--- Is this what you're asking about?
}

If that's what you're referring to, then yes, currently the library will not automatically match complex properties.

This line only returns scalar properties, excluding complex ones.

I'll examine this further, as I believe the issue can be fixed by adding the mapping of the complex properties from the entity to the audit entity.

This was fixed in version 27.0.3. Kindly update your references to the latest version and re-test. If the issue persists, feel free to leave a comment below

Thank you for the really fast, detailed response and apologies for not including a code sample. This was exactly my question and after updating to 27.0.3 it works perfectly. Thank you for the excellent library!
