I don’t know if I understand the doubt correctly, but try to adapt your forms.py according to the fragment below:

from .models import Inscricao
# Outros imports

class InscricaoForm(forms.Form):

    # Choices
    VINCULO = [
        (u'b', u'Bolsista'),
        (u'e', u'Estagiário'),
        (u't', u'Terceiro'),
        (u's', u'Servidor'),
    ]

    SALAS = [
        (u'1', u'SysAdmin'),
        (u'2', u'Help Desk'),
    ]

    # Fields
    # Outros fields ...     
    vinculo = forms.ChoiceField(choices=(VINCULO), label='Vinculo')    
    # Outros fields ...          
    sala = forms.ChoiceField(choices=(SALAS), label='Sala')

See what cities in .models is a tuple of tuples, but for ChoiceField needs to be a list of tuples.
