I have embedded discourse on my site ([Embed Discourse comments on another website via Javascript - #309 by eviltrout](https://meta.discourse.org/t/embedding-discourse-comments-via-javascript/31963/309)). Discourse creates posts containing a preview of my site. How can I recreate / refetch such an embedded post as I changed the crawler parameters and I’d like to refetch the preview of the page where discourse is embedded?

Would rebaking help? Is there a command in the console?

I found that

`TopicEmbed.find_remote(url)`

seems to be useful to show what would be fetched.

Looking through the source I found this to be a working solution:

```
username = SiteSetting.embed_by_username.downcase
user = User.where(username_lower: username.downcase).first
embed_url = "http://www.example.org" # or use the url from topic as shown below
TopicEmbed.import_remote(user, embed_url)

```

taken from **TopicRetriever.fetch\_http** ([discourse/lib/topic\_retriever.rb at 888e68a1637ca784a7bf51a6bbb524dcf7413b13 · discourse/discourse · GitHub](https://github.com/discourse/discourse/blob/888e68a1637ca784a7bf51a6bbb524dcf7413b13/lib/topic_retriever.rb#L48))

where embed\_url is the url of the site where discourse is embedded, coming from the topic with the number topic\_id this may be

```
embed_url = TopicEmbed.where(topic: topic_id)[0].embed_url

```

This seems a bit complicated to just refetch. Is it correct anyway? Is there a simpler possibility?
