# model.py 

class ModelA(models.Model): 
    id = models.AutoField(primary_key=True) 
    fielda = models.ForeignKey('ModelB', blank=True, null=True,) 


class ModelB(models.Model): 
    id = models.AutoField(primary_key=True) # In select option is value 
    name = models.CharField(max_length=254) # In select option is data 
    link = models.Integer() # I would like a new attribute in select option link

class ModelAInlinesForm(forms.ModelForm): 
    fielda = forms.ModelChoiceField(
     queryset=ModelB.objects.all(), 
     widget=forms.Select(attrs={'test': 'test1'}))

私はhttps://djangosnippets.org/snippets/2453/

class ModelAInlinesFormSelect(forms.Select): 

    def create_option(self, name, value, label, selected, index, subindex=None, attrs=None): 

     option_dict = super(SemisInlinesFormSelect, self).create_option(name, value, label, selected, index, 
                    subindex=subindex, attrs=attrs) 
     if option_dict['value']: 
      option_dict['attrs']['link'] = ModelB.objects.values().get(
       id=option_dict['value'])['link_id'] 
     return option_dict 


class ModelAInlinesForm(forms.ModelForm): 
    fielda = forms.ModelChoiceField(
     queryset=ModelB.objects.all(), 
     widget=ModelAInlinesFormSelect())
