Are you sure the idmercadoria is not None on that idproduto record?
{{ form.instance.idproduto.**idmercadoria }} Does this display anything?
How about {{ form.instance.idproduto }}?
If these don't display, verify the records in your database. In Django
templates, if something is None or does not exist, it will not raise an
exception, it just ignores it and remains blank. Also verify the referencia
field is not empty. If the field is 'NOT NULL' then it will be an empty
string if it is blank.
