wagtail 的现有 Django 站点实现。如何让 RichTextField 显示在管理员中？

Question

我已将 wagtail 添加到现有的 Django 站点。我希望将模型的内容部分更改为 RealTextField。我拥有的和我改变的如下所示：

class Post(models.Model):
    content = models.TextField()
    
class Meta:
        ordering = ['-date_added']
        
    def __str__(self):
        return self.title
         
Post(models.Model):
        content = RichTextField()
              
        class Meta:
            ordering = ['-date_added']
            
        content_panels = Page.content_panels + [
            FieldPanel('content', classname="full"),
        ]
            
        def __str__(self):
            return self.title
        
        class Meta:
            ordering = ['-date_added']
            
        content_panels = Page.content_panels + [
            FieldPanel('content', classname="full"),
        ]
            
        def __str__(self):
            return self.title
