django如何在视图中添加到表单？
|
我已发回表单，并在视图范围内添加一个字段。
编辑子弹字段。这是我决定将其隐藏在表单中并在视图中自动生成的子字段。如何将子弹字段附加到表单？
if form.is_valid():
form.[want_to_add_slug_field_here] = slugify(form.cleaned_data[\'title\'])
form.save()
class LinkForm(forms.ModelForm):
class Meta:
model = Link
exclude = (\'pub_date\', \'slug\', \'posted_by\',)

方法：class MyForm(forms.models.ModelForm): \"\"\" This is a form for your model. It includes all fields, but you won\'t display the slug field to the user. \"\"\" def clean(self): cleaned_data = self.cleaned_data cleaned_data[\"slug\"] = slugify(form.cleaned_data[\"title\"]) return cleaned_dataif form.is_valid(): instance = form.save(commit=False) instance.slug = slugify(form.cleaned_data[\"title\"]) instance.save()class MyModel(models.Model): def save(self, *args, **kwargs): self.slug = slugify(self.title) return super(MyModel, self).save(*args, **kwargs)绵扇寸访
用户从未输入过的默认值： 您需要在模型本身上覆盖save方法：def save(self,*args,**kwargs): self.slug_name = slugify(self.title) return super(MyModel,self).save(*args,**kwargs)仇聘发栖
