Get all articles from a specific category

Technical Questions
1

I created an blog-article model and a blog-category model. The blog-article model has a reference field to the blog-category model.

Now for a category page, I want to get all articles from a specific category.

My response when I get all articles looks like this:

       [
  {
    "lastUpdatedBy": "hLYQDfyMEueOo6257M6ol0fZ0ID2",
    "folders": [],
    "data": {
      "date": 1727384400000,
      "category": {
        "@type": "@builder.io/core:Reference",
        "model": "blog-categories",
        "id": "935f64738a504bc48e0508eb95f88882",
        "value": {
          ....
          "data": {
            "name": "Foo",
            "description": "Bar.",
            "url": "/foobar"
          },
          "modelId": "7d6e8a1e7bd64bffa3ccaf225bcb96bd",
          ....
      },
      "title": "Foo Bar Article title",
      "slug": "foo-bar-article",
      "teaser": "A short article teaser",
      "blocks": [

Since category is nested within the actual article: How would I filter for it, to get all articles from a specific category?

I’ve tried:

query: { 'data.category.value.data.url': '/' + route.params.slug },

However: since category is nested within the actual data, it’s not working. I hope it’s clear and thank you in advance.

Hi,

My name is Veronika and I am a Customer Engineer here at Builder.io.

Thank you for reaching out to our Forum and hopefully I can help answer your question. To filter articles by a specific category in your Builder setup - where the category is nested inside a reference, you’ll need to adjust your query to properly target that field. In Builder, you cannot query inside of a reference.

To recreate this locally, I made a list of categories and keyed into the ids.
This was my query:
{ "query.data.category.id": "50b344f9116e4820a020e382058146e0_2dd46c1332224acb955eeaa8243e75d8" }.

You can also use:
{ "query.data.category.category.id": { "$in": ["50b344f9116e4820a020e382058146e0_2dd46c1332224acb955eeaa8243e75d8", "50b344f9116e4820a020e382058146e0_c6ec4a2031f945999abaabce116dd8c1"] }} if you want to match any category ID in an array using the $in syntax in Mongo.

I believe the query you’re looking for in order to query into all the categories is:
"query.data.category.model" : "blog-category"

or if you’re looking to get the “type”
"query.data.category.@type": "@builder.io/core:Reference"

Let me know if that works for you and if you have any other questions,

Thank you!

To be a little more specific and recreate this locally, I created a list of categories and keyed into the ids.

This was my JSON response:

(I hope it’s not confusing that it’s a list of categories within a category - I wanted to test out further nesting) - but here, I queried all the categories using:

{query.data.category.category.id" : "50b344f9116e4820a020e382058146e0_2dd46c1332224acb955eeaa8243e75d8"}.

Another approach you can take is:
{"query.data.category.category.model": "blog-category"}
