通过内联显示在Django Admin中编辑/添加外键对象 [英] Editing/Adding a Foreign Key object through inline display in the Django Admin

问题描述

我的Complete_Book模型具有Book的外键。 Book是我从已安装的应用程序（即外部应用程序）中使用的东西，我希望能够直接从Complete_Book管理员编辑/创建 Book。这可能吗？我无法使用内联，因为我的外键关系是内联所允许的后退。

My Complete_Book model has a foreign key to Book. Book is something I'm using from an installed app (so, an 'outside app') I would like to be able to edit/create a 'Book' directly from the Complete_Book admin. Is this possible? I haven't been able to use inlines, as my foreign key relationship is 'backwards' from what inline allows.

我的问题与该问题中的解释相同（ but-foreign-key-has-opposite-relation> Django内联显示，但是外键具有相反的关系），但我无法按照该答案中的建议重构模型。还有其他办法吗？谢谢您的帮助！

My problem is the same as that explained in this question (Django admin inline display but foreign key has opposite relation) but I cannot refactor my models as suggested in that answer. Is there any other way? Thank you for your help!

models.py

models.py

class Complete_Book(models.Model):
    topic = models.ForeignKey('topic')
    book = models.ForeignKey(Book)
    is_primary = models.BooleanField()
    subprogram_name = models.CharField(max_length = 256, blank=True)

class Book(models.Model):
    title = models.CharField(max_length=512)
    authors = models.CharField(max_length=2048)
    year = models.PositiveIntegerField(max_length=4)

推荐答案

django_reverse_admin 是django模块，用于解决需要内联的问题，其中关系是错误的方向。

django_reverse_admin is a django module to solve this problem of needing inlines where the relationships are the 'wrong' direction.

您需要将其添加到requirements.txt中，然后将其导入：

You'll need to add it to your requirements.txt and then import it:

admin.py

from django_reverse_admin import ReverseModelAdmin

class Complete_Book(ReverseModelAdmin):
    # usual admin stuff goes here
    inline_type = 'tabular'  # or could be 'stacked'
    inline_reverse = ['book']  # could do [('book', {'fields': ['title', 'authors'})] if you only wanted to show certain fields in the create admin

admin.site.register(Book, Complete_Book)
