Am I correct in concluding that the template to generate a Data Transfer Object (DTO) for EntityFramework doesn't contain Navigation properties of an entity that are inherited from its base?
I've been trying to solve this issue myself in the template but the 'cls.RelationProperties' that is used in the GetActiveRelationProperties appears to be lacking relations that come from a base class (the base of the somewhat confusingly named baseClass actually).
Could this be retrieved somewhere, or should the RelationProperties property simply contain those and did I mess it up configuration wise or some other way?

That is correct.PeterM wrote:Am I correct in concluding that the template to generate a Data Transfer Object (DTO) for EntityFramework doesn't contain Navigation properties of an entity that are inherited from its base?
You can modify a predefined Data Transfer Object template by adding the following code in the private List<RelationProperty> GetActiveRelationProperties(BaseClass baseClass) method to add Navigation properties to an entity that is inherited from its base:PeterM wrote:Could this be retrieved somewhere [...]?
Code: Select all
var relationProperties = cls.RelationProperties
.Where(rp => rp.Generate &&
(bool)rp.GetProperty("GenerateDTO") &&
(bool)rp.Association.GetProperty("GenerateDTO")).ToList();
while(cls.BaseClass != null) {
cls = cls.BaseClass;
relationProperties.AddRange(cls.RelationProperties
.Where(rp => rp.Generate &&
(bool)rp.GetProperty("GenerateDTO") &&
(bool)rp.Association.GetProperty("GenerateDTO")));
}Code: Select all
