Question

假设我有以下模型定义：

.Parse()

现在让我们假设我想在管理站点注册模型，使用内联模型管理员允许在编辑比萨饼时添加浇头：

class Topping(models.Model):
    name = models.CharField(max_length=40)

class Pizza(models.Model):
    toppings = models.ManyToManyField(Topping)

这导致了一个相当明显的问题：

ValueType

如您所见，标签很难看。有没有办法定制它？

Answer 1

You would control what displays for an object using the __str__ or __unicode__ method.

You could manage the many to many yourself定义此属性，如下所示：

...

class Pizza(models.Model):
    toppings = models.ManyToManyField(Topping, through="PizzaToppingRelationship")


class PizzaToppingRelationship(models.Model):
    pizza = models.ForeignKey(Pizza)
    topping = models.ForeignKey(Topping)

    def __str__(self):
        return 'Pizza Topping - {}'.format(self.topping.name)

Answer 2

为关系定义模型类的更快更脏的方法是重新定义__str__或__unicode__方法：

class ToppingInline(admin.TabularInline):
    ...
    Pizza.toppings.through.__str__ = lambda self: 'Topping'

如何在内联模型管理中自定义为ManyToManyField显示的标签？
