Eagerload additional relations if a particular relation is included in the query

[abishekrsrikaanth]

So, I have a 2 relations added to my allowedIncludes method.

Let's say for example

$query->allowedIncludes(['products','saleableProducts']);

If the request includes saleable_products to be included, I want to load additional child relations for saleable_products but not when the products relation is included.

How do I go about doing this? Is there a way to check if the underlying query has a specific include included?

Or can I do

$query->allowedIncludes([
      'products',
      'saleableProducts.media',
      'saleableProducts.supplier',
      'saleableProducts.shops'
]);

and when saleableProducts is included in the request, then subsequently all the relations mentioned are automatically loaded?

Hi @abishekrsrikaanth! I'm not sure if there's an easy way to conditionally load relationships based on another relation being loaded in the same query.

Under the hood the query builder simply adds the relations you request the an Eloquent query. So for ?include=products we run $query->with('products'). This means there's no easy way to define a conditional include at the time of the request. There's ways around this but nothing supported by this package.

For your second question:

and when saleableProducts is included in the request, then subsequently all the relations mentioned are automatically loaded?

No, you have to manually add them to the URL as well: GET /shops?include=saleableProducts.media,saleableProducts.supplier,saleableProducts.shops.

Good luck!
