将 url 添加到 Django admin 中 TabularInline 中的字段

Question

问题不是真实的

如何为 TabularInline 创建来自字段作者的链接？现在我实现了这个（来源：https://stackoverflow.com/a/10011307/9112151）：

class Post(models.Model):
    title = models.CharField(max_lenght=100)
    author = models.ForeignKey('User', on_delete=models.CASCADE)


def add_link_field(target_model = None, field = '', link_text = unicode):
    def add_link(cls):
        reverse_name = target_model or cls.model.__name__.lower()
        def link(self, instance):
            app_name = instance._meta.app_label
            reverse_path = "admin:%s_%s_change" % (app_name, reverse_name)
            link_obj = getattr(instance, field, None) or instance
            url = reverse(reverse_path, args = (link_obj.id,))
            return mark_safe("<a href='%s'>%s</a>" % (url, link_text(link_obj)))
        link.allow_tags = True
        link.short_description = reverse_name + ' link'
        cls.link = link
        cls.readonly_fields = list(getattr(cls, 'readonly_fields', [])) + ['link']
        return cls
    return add_link


@add_link_field('author')
class PostInline(admin.TabularInline):
    model = Post

也许有内置的决定？

Set show_change_link = True 显示内联对象的管理员更改表单的链接

class PostInline(admin.TabularInline):
    model = Post
    show_change_link = True
