Question

我在django中有以下代码型号：

class Book(models.Model):
    book_id = models.CharField(max_length=10, primary_key=True)
    title = models.CharField(max_length=255)

class Author(models.Model):
    books = models.ForeignKey(Book)
    author_name = models.CharField(max_length=200)
    search_fields=['author_name']

class BookAdmin(admin.ModelAdmin):
    model = Book
    list_display=['book_id', 'title', 'get_author']
    search_fields = ['title', 'book_id']
    def get_author(self, obj):
    names = [a.author_name for a in obj.author_set.all()]
    return names

是否有其他方法可以在图书管理页面中显示作者列表。因为这个结果是以unicode输出作者姓名 [u'Zev Halevi'] [u'Kathryn Worth'，u'Dorothy Bayley']

另外，我需要提供一个单独的搜索栏来搜索作者。我无法使用author_name列，因为这是一个外键

Answer 1

使用此

def get_author(self, obj):
    names = "\n".join([a.author_name for a in obj.author_set.all()])
return names

django模型显示和搜索
