Then you have to build a class with a __str__() and a __unicode__() method.
The __unicode__() method should return the string that is displayed in
the combobox and the __str__() returns the value that is put in the
field of the form at the time of submit.
class MyChoice(object):
def __init__(self,val):
self.val = unicode(val,'latin_1')
self.valstr = self.val.encode('ascii','ignore')
def __str__(self):
return self.valstr
def __unicode__(self):
return self.val
_CHOICES_FORMATION = (
MyChoice('Administração'),
MyChoice('Design Gráfico'),
MyChoice('Jornalismo'),
MyChoice('Marketing'),
MyChoice('Outras'),
)
