How to Format References with Types of Posts

2 replies
Last updated: Apr 1, 2021
Hey guys, got a question.
I have an array which has references to different types of documents; for example, there’s a 
Posts
array which contains references to different types of posts such as 
merchPost
, 
classPost
, 
announcementPost
, etc. I want to query for this 
Posts
array, and then follow the references for each of the elements so that I can get expanded content for all these different types of posts. The issue I’m having trouble figuring out is how can I format each type of reference individually?
For example, this query gives me the following output:


----- QUERY
*[
  _type == "collectionFeedPosts"
  && slug.current == "feed-posts"
][0] {
  title,
  "pinnedPosts": pinnedPosts[]->
}

----- RESULT
{
  "pinnedPosts": [
    {
      "_createdAt": "2021-04-01T16:33:37Z",
      "_id": "aea7a497-7d50-45b4-af77-5f3091e570b7",
      "_rev": "p5oiLzuoOfR9bp21r2Rtt7",
      "_type": "merchContentPosts",
      "_updatedAt": "2021-04-01T16:33:37Z",
      "body": [{...}],
      "merchLink": "<http://www.url.com|www.url.com>",
      "slug": {
        "_type": "slug",
        "current": "test-merch-1"
      },
      "title": "test merch 1"
    },
    {
      "_createdAt": "2021-04-01T16:32:52Z",
      "_id": "20c66c4c-2ba9-4786-a923-4ccd19958a1a",
      "_rev": "TDo1Nq1xkiZakmRW4o2VqB",
      "_type": "mashupClassPosts",
      "_updatedAt": "2021-04-01T16:32:52Z",
      "body": [{...}],
      "slug": {
        "_type": "slug",
        "current": "test-class-1"
      },
      "title": "test class 1",
      "video": {...}
    },
    {
      "_createdAt": "2021-03-31T22:26:24Z",
      "_id": "5c723ad4-4ee9-4eeb-9cb5-c96195f9ad92",
      "_rev": "p5oiLzuoOfR9bp21r1YQuj",
      "_type": "featureAnnouncementPosts",
      "_updatedAt": "2021-03-31T22:26:24Z",
      "launchedOn": "2021-03-31T22:00:00.000Z",
      "slug": {
        "_type": "slug",
        "current": "test-1"
      },
      "title": "test 1"
    }
  ],
  "title": "Feed Posts"
}
This is just a straight output of all the references being followed. If I want to format references with 
_type == "featureAnnouncementPosts"
differently than references with 
_type == "merchContentPosts"
(f.e maybe 
merchContentPosts
should have the “slug” under a different key name), how would I go about doing this?
Thanks!

Hi Mannan. If you look at Conditionals on the Query Cheat Sheet, the bottom example (with the comment 
// Specify sets of projections for different content types …
) sounds like it might be what you’re after.

Awesome, I think that’s it. Thanks!
