我有常规的 Django User 模型和一个 UserDetails 模型(OneToOneField 和 User)，它提供作为 User 模型的扩展.(我尝试了 Django 1.5 的功能，但奇怪的是可怕的文档让我头疼，所以我坚持使用 OneToOneField 选项)
I have the regular Django User model and a UserDetails model (OneToOneField with User), which serves as an extension to the User model. (I tried Django 1.5's feature and it was a headache with strangely horrible documentation, so I stuck with the OneToOneField option)
因此，在我寻求构建一个包含 User 字段和 UserDetails 字段的注册表单的过程中，我想知道是否有从这两个相关模型中自动生成表单(及其所有验证)的方法.我知道这适用于由一个模型组成的表单:
So, in my quest to build a custom registration page that will have a registration form comprised of the User fields and the UserDetails fields, I wondered if there was a way to generate the form automatically (with all of its validations) out of these two related models. I know this works for a form made of one model:
class Meta: model = MyModel但是对于由两个相关模型组成的表单，是否有类似的功能?
But is there anyway to get a similar functionality for a form comprised of two related models?
推荐答案 from django.forms.models import model_to_dict, fields_for_model class UserDetailsForm(ModelForm): def __init__(self, instance=None, *args, **kwargs): _fields = ('first_name', 'last_name', 'email',) _initial = model_to_dict(instance.user, _fields) if instance is not None else {} super(UserDetailsForm, self).__init__(initial=_initial, instance=instance, *args, **kwargs) self.fields.update(fields_for_model(User, _fields)) class Meta: model = UserDetails exclude = ('user',) def save(self, *args, **kwargs): u = self.instance.user u.first_name = self.cleaned_data['first_name'] u.last_name = self.cleaned_data['last_name'] u.email = self.cleaned_data['email'] u.save() profile = super(UserDetailsForm, self).save(*args,**kwargs) return profile
