I do not know if it is a bug or has already been commented # models.py class State(models.Model): name = models.CharField(_('name'), max_length=60)
class Meta: verbose_name = _('state') verbose_name_plural = _('states') def __str__(self): return self.name class City(models.Model): name = models.CharField(_('name'), max_length=60) state = models.ForeignKey('State', verbose_name=_('state'), related_name ='cities') class Meta: verbose_name = _('city') verbose_name_plural = _('cities') def __str__(self): return '{} - {}'.format(self.name, self.state.name) # forms.py class AnythingForm(forms.ModelForm): class Meta: model = Anything fields = ['city'] # template.html {{form.city}} I have 5565 records in model City. Django==1.11.1 execute 5565 queries to render select Django==1.10.7 only 2 If replace return '{} - {}'.format(self.name, self.state.name) to self.name in __str__ of city model, it works.
