anzeigen Spalten der referenzierten Tabelle anstelle des Objekts in django Admin

Question

Wie kann ich zeigen die Spalten id, Titel und das Jahre des Buches statt „Bücher Objekt“?

Dieser Screenshot zeigt den aktuellen Status:

Meine model.py wie folgt aussieht:

from __future__ import unicode_literals 
from django.db import models 


class Authors(models.Model): 
    name = models.CharField(max_length=45, blank=True, null=True) 
    birthday = models.DateField(blank=True, null=True) 

    class Meta: 
     managed = True 
     db_table = 'authors' 


class AuthorsBooks(models.Model): 
    author_id = models.OneToOneField('Authors', models.DO_NOTHING, db_column='author_id', primary_key=True) 
    book_id = models.OneToOneField('Books', models.DO_NOTHING, db_column='book_id', primary_key=True) 

    class Meta: 
     managed = True 
     db_table = 'authors_books' 
     unique_together = (('author_id', 'book_id'),) 


class Awards(models.Model): 
    author = models.OneToOneField('Authors', models.DO_NOTHING, db_column='author', primary_key=True) 
    award_name = models.CharField(max_length=45) 
    year = models.IntegerField(blank=True, null=True) 

    class Meta: 
     managed = True 
     db_table = 'awards' 
     unique_together = (('author', 'award_name'),) 


class Books(models.Model): 
    titel = models.CharField(max_length=45, blank=True, null=True) 
    year = models.IntegerField(blank=True, null=True) 

    class Meta: 
     managed = True 
     db_table = 'books' 

In der Klasse AuthorsBooks ich die beiden Fremdschlüssel OneToOneFields geändert haben.

Mein admin.py sieht wie folgt aus:

from django.contrib import admin 
from myapp.models import Authors 
... 

class AwardsInline(admin.TabularInline): 
    model = Awards 

class AuthorsBooksInline(admin.TabularInline): 
    model = AuthorsBooks 

class AuthorsAdmin(admin.ModelAdmin): 
    list_display = ("name", "birthday") 
    inlines = (AwardsInline, AuthorsBooksInline) 


admin.site.register(Authors, AuthorsAdmin)

eine Unicode-Funktion in Ihrem models.py pro Modell hinzufügen.

class Authors(models.Model): 
    name = models.CharField(max_length=45, blank=True, null=True) 
    birthday = models.DateField(blank=True, null=True) 

    class Meta: 
     managed = True 
     db_table = 'authors' 

    def __unicode__(self): 
     return self.name
