Laravel declare and find composite key

Question

I am working with laravel 5.4 and my issue is how to declare a composite key in model. My composite key consists of

A_ID | S_ID

I have already research some other solutions but they weren't clear enough for me to understand.

and as the

model::find

Doesn't work with composite key, what would be the work around that?

Could you try something like this

StoreMember::where('user_id',1)->where('store_id',1)->first();
