django admin后台中如何处理外键显示？

Question

如：

    class A(models.Model):
        name = models.CharField()

    class B(models.Model):
        name = models.CharField()
        a    = models.ForeignKey(A) 

当在admin中注册A,B后，如果想要显示所有A中的b_set内容，该如何定制admin?

谢谢！

Answer 1

class BAdmin(admin.ModelAdmin):

    list_display = ['a__name', ]

---

class BInline(admin.StackedInline):
    model = B


class AAdmin(admin.ModelAdmin):
    inlines = [BInline, ]
