Getting resources that don't necessarily match Resources / NestedResource about shopify

[Ninigi]

Hmm, how should we do this... You think just returning a list would be appropriate?

Shopify.CollectionListing.get_product_ids(session, collection_id)
# => %{product_ids: [123123, 987786, ...]}

@lewisf It's pretty easy to implement, question is should we add a generic section for things that do not really justify a resource struct.

EDIT: What I mean is, are there any other endpoints that return something like this outside of count? If so, we should probably look into it.

returning a list is good but maybe also in the standard %Shopify.Response struct with code/data?

I just clicked through the api docs there's only one other instance of this:
https://help.shopify.com/en/api/reference/sales-channels/productlisting#product_ids

and I also need it :P lucky me I guess?

@Ninigi if you agree then we can move forward with this. so far it doesn't look like there are any other endpoints that return a list of ids, so maybe it makes sense to build a general escape hatch?

here's my quick analysis of the changes that need to be made:

since it seems like this is only local to these resources, we can manually add functions to make the right calls here:
https://github.com/nsweeting/shopify/blob/master/lib/shopify/resources/collection_listing.ex
https://github.com/nsweeting/shopify/blob/master/lib/shopify/resources/product_listing.ex

we'd also need to overload Shopify.Request.new to handle the case where resource isn't specified. Would it be sufficient to pass in nil as the resource here? https://github.com/nsweeting/shopify/blob/master/lib/shopify/request.ex#L30-L40

and change Shopify.Response to handle responses where something other than Shopify.resources are returned as data.

The one thing I think needs to be configured is the "singular" / "plural" of the returned data to handle parsing {product_ids: [...]} into the proper %Shopify.Response{code: 200, data: [...]} struct.

@lewisf If you have the time to look into it, it would be very much appreciated 👍

I think it might actually be not that different from a call to the count resources or spam in this resource

So it might actually not need many modifications, but if you want to come up with a fancy solution I'll be happy to do a review 👍
