How to add word to jq filter output?

Question

linux

The filter collects new json:

jq '.comments[] | {comment:{url_slug:.post.url_slug, post_id:.post.id}}'

as:

{
  "comment": {
    "url_slug": "post-solar-system",
    "post_id": 555555
  }

How can I add a given constant word in front of the url, and substitute post_id at the end so that the filter output looks like this?

{
  "comment": {
    "url_slug": "post-solar-system",
    "post_id": 555555
    "full_url": "https://экзампл.ком/post-solar-system-555555/"
  }

Answer 1

Something like this

full_url:("https://example.com/" + .post.url_slug + "-" + (.post.id | tostring))
