18154	Too many open files.	eltonplima@…	Gabe Jackson	"I'm doing a migration between two applications in django, everything was going normal until I got a class that has a field of type FileField. The import function normally to a given time in the system raises the following exception:

Original exception was:

That is, django is opening each file but is not closing, so I'm forced to close it manually, in theory django should not automatically close the file?

My code:


{{{
conversoes = ArquivoProtocolo.objects.using('protocolo').all()
if conversoes.count() > 0:
    for conversao in conversoes:
        ProtocoloRelatorioArquivo.objects.get_or_create(
         id=conversao.id,
         tipo_relatorio=TipoRelatorio.objects.get(id=conversao.tipo_relatorio.id),
         arquivo=conversao.arquivo,
         protocolo_relatorio=ProtocoloRelatorio.objects.get(id=conversao.protocolo_arquivo.id)
        )
        conversao.arquivo.close()# This should really be necessary?
