如何在保存前更改 wagtail 页面标签?

我可以像这样覆盖 save() 来更改标题-

class ProductPageTag(TaggedItemBase):
    content_object = ParentalKey('product.ProductPage',related_name='tagged_items')

class ProductPage(Page):
    body = StreamField(BodyStreamBlock)
    tags = ClusterTaggableManager(through=ProductPageTag, blank=True)
    def save(self, *args, **kwargs):
      self.title = "my title" # work
      self.tags = "test,test2,test3" #not work
      super(ProductPage, self).save()

但我不知道如何更改标签列表。

我找到了答案:D

刚好需要改变

self.tags = "test,test2,test3"

self.tags.add('test',"test2","test3")

最终代码

class ProductPageTag(TaggedItemBase):
    content_object =ParentalKey('product.ProductPage',related_name='tagged_items')

class ProductPage(Page):
    body = StreamField(BodyStreamBlock)
    tags = ClusterTaggableManager(through=ProductPageTag, blank=True)

    def save(self, *args, **kwargs):
      self.title = "my title" # work
      self.tags.add('test',"test2","test3") #work
      super().save(*args, **kwargs)

(或者,在使用旧的 Python 2.7 时,super(ProductPage, self).save(*args, **kwargs)
