Rails Get Multiple by ID

ruby-on-rails

Solution

I don't think you should need to change the routes at all. You should just have to parse them in your controller/model.

def show
  @products = Product.find params[:id].split(',')
end

If you then send a request to `http://localhost/products/1,3,9,24`, @products should return 4 records.

Problem

In Rails, I have a `Product` model. Sometimes I need to get multiple `products` at the same time (but the list is completely dynamic, so it can't be done on the Rails side). So, let's say for this call I need to get products 1, 3, 9, 24 in one call. Is this possible? If so, do I need a custom route for this and what do I put in my controller? i.e. does something like this work? `/products/1,3,9,24`
