Method:

What’s the mistake? Can you please put it in your question?

I didn’t overwrite Onmodelcreating that would be what?

@Warlock, in this case it is important put to Innerexception, ie the one that actually contains useful information about the error. However when it comes to Entity Framework, I will ask you to make a Try with 2 catch, one for Dbentityvalidationexception and one for Exception.

– Tobias Mesquita

2015/02/09 at 13:27
As I see this innerexception?

– War Lock

2015/02/09 at 13:28
I put a catch for Dbentityvalidationexception, but in debug it already goes to Exception

– War Lock

2015/02/09 at 13:31
Put a breakpoint in the Exception, and expand it until you get the innermost exception.

2015/02/09 at 13:33
I will post the complete error

Cannot Insert Duplicate key in Object TEST.ARQUIVO_VERSAO'. The statement has been terminated. You are trying to insert a duplicate Key into the Bank.

In this answer teach to capture an internal context exception using Entity Framework.

that error is in the method I posted?

@Warlock What is the primary key of ArquivoVersao?

– Leonel Sanches da Silva

2015/02/09 at 13:45
@Warlock, could you reset the entity diagram?

– Tobias Mesquita

2015/02/09 at 13:46
ARQUIVO_VERSAO_GUID is the PK, posted the diagram

The error is quite clear:

System.Data.SqlClient.SqlException HResult=-2146232060 Message=Violation of PRIMARY KEY constraint 'ARQUIVO_VERSAO_PK'. Cannot insert duplicate key in object TEST.ARQUIVO_VERSAO'. The statement has been terminated.

It means that here:

            ARQUIVO_VERSAO = new ARQUIVO_VERSAO()
            {
                ARQUIVO_GUID = arquivo.ARQUIVO_GUID,
                ARQUIVO_VERSAO_GUID = versao.ARQUIVO_VERSAO_GUID, // Isto já existe no banco
                ARQUIVO = versao.ARQUIVO,
                DATAHORA = versao.DATAHORA,
                TAMANHO = versao.TAMANHO,
                USUARIO_PESSOA_GUID = versao.USUARIO_PESSOA_GUID
            },

The right thing would be for you to generate one Guid new for each new inserted version. As the column is String, still needs one more conversion:

            ARQUIVO_VERSAO = new ARQUIVO_VERSAO()
            {
                ARQUIVO_GUID = arquivo.ARQUIVO_GUID,
                ARQUIVO_VERSAO_GUID = Guid.NewGuid().ToString(),
                ARQUIVO = versao.ARQUIVO,
                DATAHORA = versao.DATAHORA,
                TAMANHO = versao.TAMANHO,
                USUARIO_PESSOA_GUID = versao.USUARIO_PESSOA_GUID
            },

ops, from conversion error to string

converted, I’ll test it

@Ciganomorrisonmendez, for some reason he saves and manipulates Guids as text, just don’t ask me why.

– Tobias Mesquita

2015/02/09 at 13:57
worked well worth ...

– War Lock

2015/02/09 at 13:59
Giving another Entity Exception, I must create another theme?

– War Lock

2015/02/09 at 14:04
@Ciganomorrisonmendez, the only problem I see in this answer, is that you are discarding the PK that is in the Archive. If this is an integration or conciliation program, this can cause many problems.

– Tobias Mesquita

2015/02/09 at 14:04
@Warlock should. It’s another problem now.

– Leonel Sanches da Silva

2015/02/09 at 14:05
I figured that out Toby, but at the time it solved, and I don’t think I’m gonna have a problem with that.

– War Lock

2015/02/09 at 14:05
@Tobymosque I do not know what makes his logic. To answer this does not seem to be important.

@Warlock, this "I think" gave me an impression that it lacks an understanding of the project as a whole, in its place would look for the architect of this system.

You are trying to insert an ARQUIVO_VERSAO object that already exists, in this case you need to check if it already exists in the Database. You can do it as follows:

using (var ctx = new TESTEntities())
{
    var versaoAux = arquivo.ArquivoVersoes[0];
    var versao = ctx.ARQUIVO_VERSAO.Find(versaoAux.ARQUIVO_VERSAO_GUID);
    if (versao == default(ARQUIVO_VERSAO)) 
    {       
        versao = new ARQUIVO_VERSAO()
        {
            ARQUIVO_GUID = arquivo.ARQUIVO_GUID,
            ARQUIVO_VERSAO_GUID = versaoAux.ARQUIVO_VERSAO_GUID,
            ARQUIVO = versaoAux.ARQUIVO,
            DATAHORA = versaoAux.DATAHORA,
            TAMANHO = versaoAux.TAMANHO,
            USUARIO_PESSOA_GUID = versaoAux.USUARIO_PESSOA_GUID
        };
    }

    ctx.ARQUIVO.Add(new ARQUIVO()
    {
        ARQUIVO_GUID = arquivo.ARQUIVO_GUID,
        ARQUIVO_VERSAO = versao,
        DIRETORIO_GUID = arquivo.DIRETORIO_GUID,
        EXTENSAO = arquivo.EXTENSAO,
        IS_STREAM = arquivo.IS_STREAM,
        TAG = arquivo.TAG,
        TIPO_DE_ARQUIVO_GUID = arquivo.TipoDeArquivo.TIPO_DE_ARQUIVO_GUID,
        ULT_ARQUIVO_VERSAO_GUID = arquivo.ULT_ARQUIVO_VERSAO_GUID,
        URL = arquivo.URL,
        XARQUIVO = arquivo.XARQUIVO
    });
    ctx.SaveChanges();
}
