Django多个嵌套在线表单 [英] Django Multiple Nested inline formsets

问题描述

这是否可能？

我需要存储一些要检索的文件作为json / rest。

I need to store some documents to be retrieved as json/rest.

A 文件有许多部分，而一个部分有一个标题，一个正文和许多图片。

A Document has many Sections, and a section has a heading, a body and many Images.

有没有办法可以使用这种结构的表单？

Is there a way I can make a form with this structure?

Publication
|-- Section
    |-- Image
    |-- Image
|-- Section
    |-- Image
|-- Section
    |-- Image
    |-- Image
    |-- Image

我的模型：

class Publication(models.Model):
    title = models.CharField(max_length=64)

class Section(models.Model):
    publication = models.ForeignKey(Publication)
    heading = models.CharField(max_length=128)
    body = models.TextField()

class Image(models.Model):
    section = models.ForeignKey(Section)
    image = models.ImageField(upload_to='images/')
    caption = models.CharField(max_length=64, blank=True)
    alt_text = models.CharField(max_length=64)

当 Image 与相关的出版物时，因为只有一个级别的嵌套。

I can do this relatively easy when Image is related to Publication, because there is only one level of nesting.

当 Image 属于 / code>，但是，我不知道如何构建表单。
似乎没有简单的方法来做这个内联表单。

When Image is belongs to Section, though, I'm not sure how to build the form. It seems as though there's no easy way to do this with inline formsets.

任何人都可以帮助？

推荐答案

这不能在vanilla Django中完成。我使用 django-nested-inlines ，它的效果非常好。

This can't be done in vanilla Django. I use django-nested-inlines for this and it works really well.

from django.contrib import admin
from nested_inlines.admin import NestedModelAdmin, NestedTabularInline

from my.models import Publication, Section, Image


class ImageInline(NestedTabularInline):
    model = Image


class SectionInline(NestedTabularInline):
    model = Section
    inlines = [ImageInline,]


class PublicationAdmin(NestedModelAdmin):
    inlines = [SectionInline,]


admin.site.register(Publication, PublicationAdmin)
