Entity Framework - Update entity with child properties?

You can directly click update from model in entity framework and it will automatically update the enitty with all the relationship.

The "create" statement is like this: public ActionResult Edit(FormCollection form) { Usuario usuario = new Usuario { NomeUsuario = form"Usuario. NomeUsuario", IdeUsuario = form"Usuario. IdeUsuario", NumRegistroRM = form"Usuario.

NumRegistroRM", SenUsuario = form"Usuario. SenUsuario", SituacaoUsuario = this. SituacaoUsuarioService.

GetSituacaoUsuario(x => x. ID_SituacaoUsuario == Convert. ToInt32(form"Usuario.

SituacaoUsuario"// note that I have to retrieive the entire object... the "child" }; this.UsuarioService. AddUsuario(usuario); } the edit statement should be like this: TryUpdateModel(a, "Usuario", this. GetUsuarioWhiteList(), form.ToValueProvider()); // but the form contains only the id and I can't load the child in it nor pass the object.

I had the same issue recently and I managed to solve it when I changed the cardinality ratios for my foreign keys in the child table from 1:many to 0..1:many in the Entity Designer and it worked fine.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
