Django - 管理站点中OneToOne字段的内联表单 [英] Django - Inline form for OneToOne field in admin site

问题描述

这个问题已经被问了很多次，但不幸的是，我找不到一个实际可行的答案。以下是我的模型：

Hi This question has been asked many times but unfortunately I could not find an answer for it that would actually work. Below are my models:

class Person(models.Model):
    name = models.CharField(max_length=100)
    ...

class Address(models.Model):
    person = models.OneToOneField(Person)
    ...

然后在管理员中我有：

class AddressInline(admin.StackedInline):
    model = Address


class PersonAdmin(admin.ModelAdmin):
    inlines = (AddressInline)

admin.site.register(Person, PersonAdmin)

然后我得到这个臭名昭着的错误：

and then i get this infamous error:

<class 'address.models.Address'> has no ForeignKey to <class 'person.models.Person'>

我尝试过：

• django-reverse-admin。不幸的是没有使用Django 1.6，而且我没有足够的空间使其能够与1.6一起工作。


• 在使用代理模型和抽象基类并且没有工作的情况下，stackoverflow中有几个提示。

如果有人可以帮助我找到解决方法，我真的很感激。

I would really appreciate if someone could help me to find a workaround for it.

推荐答案

我没有尝试过，但这个要点似乎是基于django-reverse-admin中的代码，但更新为在Django 1.6上工作：

I have not tried it, but this gist appears to be based on the code in django-reverse-admin but updated to work on Django 1.6:

https://gist.github.com/mzbyszewska/8b6afc312b024832aa85

请注意，这部分示例代码是错误的：

Note that this part of the example code is wrong:

class AddressForm(models.Form):
    pass

...您需要从django导入表单在顶部，然后执行以下操作：

...you need to from django import forms at the top and then do something like:

class AddressForm(forms.ModelForm):
    class Meta:
        model = Address

这里的第46行示例代码中还有另一个问题：

There's another problem in the example code here line #46:

inline_reverse = ('business_addr', ('home_addr', AddressForm), ('other_addr' (
    'form': OtherForm
    'exclude': ()
)))

应该可能是：

inline_reverse = ('business_addr', ('home_addr', AddressForm), ('other_addr', {
    'form': OtherForm,
    'exclude': ()
}))

注意，它显示了三种不同的方式来指定内联...第一个只是通过字段名称'business_addr'即如果你不需要内嵌模式的自定义表单。

note that it shows you the three different ways to specify an inline... the first is just by field name 'business_addr' i.e. if you don't need a custom form for the inline model.
