如何显示本书的 id title 列而不是" Books对象"

此屏幕截图显示了当前状态:

enter image description here

我的model.py看起来像这样:

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'

在AuthorsBooks类中,我将两个外键更改为OneToOneFields。

我的admin.py看起来像这样:

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)

在models.py中为每个模型添加一个unicode函数。

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

在您的models.py文件中,您可以在所关注的类中使用特殊的__str__方法来使您的对象更具描述性。 (通常这是大多数程序员这样做的方式)

def __str__(self):
    return self.title #if your using 'title' as the attribute to identify your objects

您可以选择任何其他属性来使您的对象具有描述性。

祝你好运!

Unicode对我不起作用,但是覆盖 str 可以有效
