Ruby link_to options

I need to add an id element into a session array in my rails application. I have the id when I bring up this view, product.id, and i have my session, called session[:cart], waiting for input.

I want to push that id into the session when I click on the link below.

<%= link_to "Add to Cart", controller: "my_cart" %>

Is there more to this link I add? i have been looking all over the internet and have not come up with exactly what I'm looking for.

Please help

Solution

  • You need to pass your product.id to some controller/action where that controller/action will add the product id to the session. It cant be done on the browser side as Sessions are server driven

    <%= link_to "Add to Cart", add_product_to_cart_path(:product_id => product.id) %>

    and method would be something like

    def add_product_to_cart

    session[:cart] << params[:product_id]

    end
