如何在django管理员的编辑页面中添加“预览”按钮？

Question

After long searches, I still didn't find any answers I've been able to apply.

I have in my django app a models which creates new pages in the website:

class Page(models.Model):
    name = models.CharField(max_length=255, null=False, blank=False, unique=True)
    content = HTMLField('Content')
    slug = models.CharField(max_length=255)
    background_image = models.ImageField(
        upload_to="page_background/",
        null=False,
        blank=False,
        default="default/livresse_logo.png",
    )

As you can see there's a WYSIWYG editor in it, a title and a background image.

When I go to the admin page it's like this:

I'm looking for a way to add a button 'preview' (maybe next to the save button) that would show the content of my model included in the template that will be use to display the page before saving. I'd like this button only displaying for that model. Hope i'm clear enough.

我不确定是否有一个优雅的解决方案，但你可以稍微改变一下你的问题，在模型中实现布尔参数is_published，并以这样的方式编写视图，使得只有尚未发布的文章才被看到由超级用户，所以我通常组织预览。
