I’ve got a site with 750+ categories and need to change the text in the “About this category” post to "Blah. Category Name. Blah’.
I’ve tried doing something like this:
```ruby
desc='Blah. %s Blah.'
c = Category.where("name like '%whatever%'").first
p = Post.where(topic_id: c.topic_id).first
t = Topic.find(c.topic_id)
p.raw = desc % c.name
p.cooked=p.cook(p.raw)
p.save
```
but it doesn’t change the text in the post, much less the excerpt for the topic or the category description.
What am I missing?

Did you try editing the post? I’d replace the last 3 lines of your code snippet with
```ruby
p.revise(Discourse.system_user, { raw: desc % c.name }, bypass_bump: true)
```

That looks like what I was looking for! I tried to figure out `Post.revise`, but couldn’t quite get the parameters. Thanks, @gerhard!
And Rails will magically fix up the Topic excerpt and the Category description? (I suppose I’ll know soon enough when I test it tomorrow).
