encoding - Django admin UnicodeDecodeError when adding -

i'm having problems when adding elements in django interface. have 2 definitions:

# -*- coding: utf-8 -*- class visittype(models.model):     name=models.charfield(max_length=50,db_index=true,verbose_name="nombre del tipo de visita")     is_basal=models.booleanfield(default=false,verbose_name="es basal")      def __unicode__(self):         if self.is_basal:             s="%s [basal]" % (self.name)         else:             s="%s" % (self.name)         return s  class visit(models.model):     type=models.foreignkey(visittype,null=true,on_delete=models.set(visittype.get_sentinel_visit_type),db_index=false,verbose_name="tipo de visita")      def __unicode__(self):         return "tipo de visita %s" % (self.type) 

when adding visittype object in admin site, there no problem. adding_visittype

but, when adding visit in admin: adding_visit

i unicodedecodeerror hint: "the string not encoded/decoded analtica" (notice used "analítica" visit type in form.

i'm using django 1.5.1, mysql-python 1.2.4.

the mysql using tables utf8_general_ci collation.

the database mysql 5.5.30.

regards.

neither of __unicode__ methods return unicode strings. both return byte strings. recipe disaster. when inside functions you're interpolating unicode byte strings.

do instead:

def __unicode__(self):     if self.is_basal:         s = u"%s [basal]" % (self.name)     else:         s = self.name     return s 

and:

return u"tipo de visita %s" % (self.type)
