主/详细页面的 Django 管理应用程序

考虑 Django 中的这个简化模型：

class Item(models.Model):
    title = models.CharField(max_length=200)
    pub_date = models.DateTimeField()

class ItemDetail(models.Model):
    item = models.ForeignKey(Item)
    name = models.CharField(max_length=200)
    value = models.CharField(max_length=200)
    display_order = models.IntegerField()

有没有一种方法可以使用 admin 在同一页面上编辑项目及其详细信息，其表单如下所示

title:    <       >
pub_date: <       >
details:
+-----------------+----------------------+-------------------------+
|       name      |        value         |      diplay order       |
+-----------------+----------------------+-------------------------+
|<               >|<                    >|<                       >|
|<               >|<                    >|<                       >|
|<               >|<                    >|<                       >|
|<               >|<                    >|<                       >|
|<               >|<                    >|<                       >|
+-----------------+----------------------+-------------------------+

： > 将是数据输入的输入类型的占位符。

所以，我的问题是：我可以使用 admin 从父级的角度编辑外键关系吗？如果没有办法用 Django 的 admin 来编辑数据，那么尝试扩展/自定义 admin 来做到这一点是个好主意吗？有关如何执行此操作的任何指示？

谢谢！

Consider this simplified model in Django:

class Item(models.Model):
    title = models.CharField(max_length=200)
    pub_date = models.DateTimeField()

class ItemDetail(models.Model):
    item = models.ForeignKey(Item)
    name = models.CharField(max_length=200)
    value = models.CharField(max_length=200)
    display_order = models.IntegerField()

Is there a way to use admin to edit an Item with its details on the same page with a form that looks something like:

title:    <       >
pub_date: <       >
details:
+-----------------+----------------------+-------------------------+
|       name      |        value         |      diplay order       |
+-----------------+----------------------+-------------------------+
|<               >|<                    >|<                       >|
|<               >|<                    >|<                       >|
|<               >|<                    >|<                       >|
|<               >|<                    >|<                       >|
|<               >|<                    >|<                       >|
+-----------------+----------------------+-------------------------+

Where < > would be placeholder for input types for data entry.

So, my question: can I use admin to edit a foreign key relationship from parent's perspective? If there isn't a way to edit data with Django's admin this way, would it be a good idea to try to extend/customize admin to do this? Any directions on how to do this?

Thanks!

这实际上是 django 擅长处理关系的唯一方向——反之则更困难（直接编辑子级的相关父级）。

要获得您想要的格式，请查看 ModelAdmin 内联：
http://docs.djangoproject.com/ en/dev/ref/contrib/admin/#django.contrib.admin.InlineModelAdmin

class ItemDetailInline(admin.TabularInline):
    model = ItemDetail

class ItemAdmin(admin.ModelAdmin):
    inlines = [
        ItemDetailInline,
    ]

That's actually the only direction django is good at dealing with relationships for -- the other way around is harder (directly editing the related parent from the child).

To get the format you want, look into ModelAdmin inlines:
http://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.InlineModelAdmin

class ItemDetailInline(admin.TabularInline):
    model = ItemDetail

class ItemAdmin(admin.ModelAdmin):
    inlines = [
        ItemDetailInline,
    ]
