is it possible to reference something created in the same mutation? i.e.:

db.updateUser({
    where {
    userid:'123'
    }
    data: {
        posts: {
            create: {
                name:'my new post'
            }
        },
        actions: {
            create:{
                actionType: 'posted',
                post: {
                    // somehow connect the above created post?
                }
            } 
        }
    }
});

No, you need to make separate calls but prisma client batches things internally so this will result in one db call in the end

@Harshit thank you!

Great :)
