我正在尝试在django Admin中自定义多个内联,但是我无法显示底层模型的字段.

这是一个简化的例子.也许你可以告诉我如何引用它们？

这是我的模特:

class Clown(models.Model):
    name = models.CharField(max_length=255)
    def edit_link(self):
        return ...

class Circus(models.Model):
    clowns = models.ManyToManyField(Clown, blank=True, through='WorkedAt')
    name = models.CharField(max_length=255)

class WorkedAt(models.Model):
    clown = models.ForeignKey(Clown)
    circus = models.ForeignKey(Circus)

和我的管理员:

class ClownInline(admin.TabularInline):
    model = WorkedAt
    fields = ['clown__name','clown__edit_link']


class CircusAdmin(admin.ModelAdmin):
    inlines = [
        ClownInline,
    ]
    exclude = ('clowns',)

但是我收到此错误:

Unknown field(s) (clown__name) specified for WorkedAt

(我在Django 1.6上)

更新: 为什么这不起作用.(通过模型添加计算字段.)

class Clown(models.Model):
    name = models.CharField(max_length=255)
    def edit_link(self):
        return ...

class Circus(models.Model):
    clowns = models.ManyToManyField(Clown, blank=True, through='WorkedAt')
    name = models.CharField(max_length=255) …
