为w的模型的每一页修改段塞 [英] Modify slug for every page of model on wagtail

问题描述

我试图为Wagtail上的特定Page模型的每个页面创建一个自定义标签.我一直在调查并尝试 RoutablePageMixin 示例，但这似乎修改了url结构，而不是段本身.

I am trying to create a custom slug for every page of a specific Page model on Wagtail. I have been looking into and tried the RoutablePageMixin examples, but that seems to modify the url structure, not the slug itself.

这就是我想要做的:

当前页面标题:关于Django

Current page title: About Django

当前页面提示:about-django

current page slug: about-django

我想要的页面标题:关于Django

page title I want: About Django

我想要的页面:awesome-things-about-django

page slug I want: awesome-things-about-django

我看过创建路由方法，但这似乎并没有修改.有什么办法可以将一些东西放在您的鼻涕虫上吗?我知道我可以手动执行此操作，但希望它可以自动执行.

I looked at creating route method, but that didn't seem to modify the slug. Is there any way to prepend something onto your slug? I understand I can do this manually, but would prefer for it to happen automatically.

推荐答案

保存时自动更新页面的一种可能性是覆盖 full_clean 方法:

One possibility for making automatic updates to pages on save is to override the full_clean method:

class MyPage(Page):

    # ...

    def full_clean(self, *args, **kwargs):
        # first call the built-in cleanups (including default slug generation)
        super(MyPage, self).full_clean(*args, **kwargs)

        # now make your additional modifications
        if not self.slug.startswith('awesome'):
            self.slug = "awesome-%s" % self.slug
