How to get category details for each up_sell product ?

I need to get up_sell products' categories while fetching the given product details. Currently, the given product details object contains a up_sells array with only id and product_id and I'm able to expand the product object also for each upsell by the following query.

But inside the product object for each up_sell item, I'm not able to get its category details and I can't also expand its category by using expand: [ 'up_sells.product.category']

  • @Gaurav Pandey Brilliant question and nice attempt.

    You should have tried 'up_sells.product.categories'Β to expand the categories for each up_sell item.

    Hope this answers your question. If not, please reply to this thread and I am happy to answer you.

  • @Logesh_Dinakaran I had tried this also, but it didn't work. Throws the permission error.

    @Gaurav Pandey Sorry, I assumed that you were testing in swell-node and the previous answer would work with backend APIs and not in swell-js (or frontend APIs)

    You cannot fetch more than 1-level deep using swell-js. But, there's a workaround for this and please let me know whether this works for you.

    response = await swell.categories.list({
      "id": {
        "$in": ["category_id_1", "category_id_2"]
      }
    });
    

    I guess that you may already explore this option as well, but this is the only option available at the moment for swell-js. I would also like to understand your use case for this requirement so that I can check with my product team whether we could include this pattern in the query permissions.

  • hey @Logesh_Dinakaran this only fetches a list of categories. I am looking for category details while expanding the up_sells products list in a given product object.

    My use-case is pretty straightforward - I want category details to appear in up_sells products because, in the UI, I am showing up_sell products cards (as related products).

    My product details page URL has category_slug for SEO purposes.

    Now each up_sell product card links to its details page and this link is broken now due to missing category details.

  • @Gaurav Pandey Thanks for sharing your use case. So, you want to fetch a list of upsell products for a given product and each upsell product should navigate to a URL generated using upsell product's category slug.

    If my understanding is correct, please follow the below steps:

    1. Fetch a list of upsell products for a given product

    let productDetail = await swell.products.get('product_id', {
      expand: 'up_sells.product'
    })
    

    2. Load category details for the available upsell products.

    // Fetch the unique category_ids for the available upsell products.
    let categories = new Set();
    productDetail.upSells.forEach(upSell => {
      upSell.product.categoryIndex.id.forEach(categoryId => categories.add(categoryId))
    })
    
    // Lookup category details for those unique category_ids via a single query
    let categoryList = await swell.categories.list({
      'id': {
        '$in': Array.from(categories)
      }
    })
    
    let categoryMapper = {}
    categoryList.results.forEach(category => {
      categoryMapper[category.id] = category
    })
    

    3. Display the upsell items with a corresponding category-slug.

    productDetail.upSells.forEach(upSell => {
      upSell.product.categoryIndex.id.forEach(categoryId => {
        let productUrl = `https://store_id.swell.store/products/${categoryMapper[categoryId].slug}`
        console.log(productUrl)
      })
    });
    

    Hope this answers your question. If not, please reply to this thread and I am happy to answer you.
